Chilean Mining Investments – Project Portfolio 2015 -2024

DEPP 13/2015

Intellectual Property Registry © #256,643 Chilean Mining Investments – Project Portfolio 2015 -2024 1

Brief

The objective of this Assessment is to show the updated portfolio of mining projects in , the estimate of investments required to carry it out in the 2015- 2024 period, and the impact upon the production capacity which the resulting productive contribution would have from the investing processes which would be registered in the aforementioned period up to 2024. The portfolio is made up of two groups of initiatives, the first of which correspond to those projects with a greater probability of materializing in the timeframes indicated by the owning companies, which are those in a base and probable condition, a total of 24 initiatives assessed in $31,345 million USD. Furthermore, the second group of projects corresponds to those in a possible and potential condition, meaning mining investments with lesser probability of materializing in the time frames established by the owners, as well as those prone to being affected by changes in market conditions, which total 18 initiatives assessed in $45,945 million USD. The most important part of this project portfolio is not the global value thereof, rather the composition in terms of the number of initiatives, those driving them, their objectives, their location, and the efforts being made to carry them out. Upon analyzing the investments within the investment portfolio, three phases can be identified: - Investment already raised, which corresponds to $15,415 million USD, or 19.9% of the current portfolio, - The investment to be raised during the next five year period, 2015-2019, for $44,894 million USD, equaling 58.1% of the portfolio, with an average yearly investment of $8,979 million USD, - The remainder to be invested in the 2020-2024 period, during which those projects whose commissioning is anticipated to happen during that time have an investment total which reaches $16,981 million USD, equaling 22% of the investment portfolio. Within the investment to be raised during the next five year period, the project group with the base and probable conditions make up 40% of the investment, with an average rate of $3,592 million USD. Likewise the group of initiatives in possible and potential conditions make up the remaining 60%, with an annual investment average of $5,386 million USD. This investment primarily seeks to increase the productive capacity, which translates into an increase in the supply available to the international market. In the case of copper, and considering the horizon through 20261, Chile has the potential to reach a maximum copper production of 7.56 million tons of copper, 31.6% above the production registered

1 Two years after the last year of the commissioning thereof as registered in this portfolio.

in 2014, if all of the anticipated projects are carried out through 2024, wherein copper production would reach approximately 7.84 million tons, a 36.3% increase over 2014 production. It is worth noting that if only the initiatives with a base and probable condition are carried out, the copper production of the country will fall by 6.4% to around 5.4 million tons of fine copper. If, to this scenario, we add the materialization of the initiatives which are possible this would counteract the loss in production, reaching 6.6 million tons of fine copper, a 15.4% production increase with respects to 2014. This increase in production would reflect a structural change in the type of final product of the copper producing operations, as the maximum capacity of concentrate production would increase by 2.84 million tons by 2026, a 72.7% increase from 2014, the production of SxEw cathodes would diminish by 1.03 million tons, registering a decrease of 55.7% with respects to the same year. In the case of gold, it is expected that by 2026 the maximum capacity of this metal could reach 80.5 tons of gold content, a 75% increase over the 46 tons registered in 2014, while the projects included in this report with potential production of silver would reach 1,495 tpa of silver by 2026 over current production, which in 2014, reached 1,572 tons of silver. In the case of molybdenum, the principal by-product of copper mining, the maximum recovery capacity of molybdenum will reach 95.6 thousand tpa by 2026, a 96% increase with respects to the amount produced in 2014, which implies a yearly average rate of 5.3%. The projects with primary production or by-production of iron considered in this report will contribute 18.8mt of iron mineral by 2026, approximately 11.9 Mt of fine content, to reach a maximum production of around 33.3 Mt of iron ore, which is an 80% increase with respects to the quantity registered in 2014. In the case of industrial minerals, there are two initiatives in the area of saltpeter, the first of which would contribute 10,000 tpa of iodine equivalent, and around 1,293,000 tpa of NaNO3. The second initiative would produce around 2,700 tpa of iodine, and 400,000 tpa of nitrates, including 20,000 tpa of boric acid. It is interesting to point out that there is also an initiative to produce titanium dioxide (TiO2) at a capacity which is estimated at 200 ktpa of concentrate (95% of TiO2).

1. Introduction

The following report corresponds to a new update of the yearly report about investments in Chilean mining for the next decade, which is part of a line of work carried out by the Chilean Copper Commission and the Department of Studies and Public Policies for the past almost 10 years. The information herein contained is on based on public records available through June 2015, having the primary objective of providing pertinent information about the registry of mining projects which are currently valid in Chile, with the following projection of the expected investment and the potential capacity of mining production in Chile, considering the productive contribution which results from the investment process during the next ten years. The registration of the mining initiatives in this report does not assure they will materialize within the terms and timeframes planned by the companies, however it shows the interest they have to advance in their current mining activities, in the case of the companies with operations in Chile, or to begin mining in our territory, having considered the geologic potential of the available mining property as well as the economic and political perspectives in the country in the long term. This report is structured in the following manner: a) Specification of the methodological criteria used for the elaboration of this report, showing coverage, attributes which coincide with the condition that each project is in, with the purpose of measuring the level of certainty of the available information, information sources, criteria to estimate the start-up date if it is not readily available, and the estimate of the copper production capacity and of that of other minerals in the long term. b) Analysis of the investment required for the copper mining project portfolio, as well as that of gold, silver mining, iron mining, and that of some industrial minerals, with respects to the conditionality of these initiatives, the purpose of the investment, the regional distribution and the countries wherein the investments originate. The descriptive background of each of the projects considered is included in Annex 1 (copper mining), Annex 2 (gold and silver mining) and Annex 3 (industrial minerals: iodine, nitrates, potassium salts, and titanium oxide,) respectively. c) An estimate of the investment flow coming from the project profile, indicating the amounts already invested, the yearly flow during the next decade, and the amount to be invested after the next five years. It is to be noted that this projection is only referential and does not constitute a commitment with the companies which own the projects. d) Furthermore, and as a result of the investment process, the productive contribution of these projects is shown, through projections of the maximum production capacity of the copper mine, in concentrates such as SxEw cathodes, looking toward 2026 (two years after the last start-up registered in this report) and focusing on the conditionality of the initiatives. Additionally, a global estimate is given for the future production of gold, silver, molybdenum, iron and the industrial minerals considered. As in the case of the

Chilean Copper Commission

Chilean Mining Investments – Project Portfolio 2015 -2024 8

annualization of the investments, the production estimates are only referential based on the methodologies and information sources described at the beginning of this document. e) As in the previous two years, a registry is made as a form of comparison of the changes which have been registered between the current project portfolio and the previous, showing variations in investment amounts as well as in the quantity of initiatives considered. In this opportunity a vision is given on a level of the conditionality of the projects, investment purpose, and comparison on a regional level of the changes produced. Finally it concludes with the most relevant background information which can be taken from the information given.

2. Methodology

The Methodology which is used for the confection of this register is based on the following criteria:

2.1. Coverage

The project register covers the investments with productive purposes (reposition or expansion of the production or new development) anticipated by CODELCO and the private companies of the large and medium metal and non-metal mines, excluding energy minerals. Only projects with investments which surpass 90 million dollars are included, as are those which are already being carried out as well as those in which the companies are assessing and have the intention of initiating the investment process within a five year period. For the effects of the yearly distribution of the estimated investment for each project, included is the sum of the investments already in place from the beginning of the project until the end of the year prior to the present report under the concept of “Before xxxx” wherein “xxxx” corresponds to the publication year of the report. Then the estimated investment is assigned for each year of the next five year period. Similarly, for those projects which will begin operations after the next five year period, it is presented as “Investment after xxxx”, wherein “xxxx” is the year after the last year of the present five year period, for the accumulated investment which will be carried out until the operations begin. It is worth noting that the information compiled in this document is the best approximation known of the projects being considered. In some cases, without other public information, the yearly distribution of the investments are estimates of the authors and are not binding in any way for the companies who own the projects. The background information of each project includes an estimate of the production of metals which they would supply, when it corresponds to such, as well as the indication of the current state of the project.

2.2. Attributes of the projects and the conditions of carrying them out

The information about the investment projects is characterized by the uncertainty due to the quantity and quality of the background information available, which depends on the attributes of the projects up to the date in which the registry is made.

2.2.1. Conditions for the materialization

Each attribute has a degree to which it may be associated to a greater or lesser degree of certainty and the combination of which will give a perception of the conditionality in which it is found to be carried out. Therefore, there are 4 conditions defined: Basic, probable, possible, and potential, as associated with the specific attributes which are detailed in Table 1:

Chilean Copper Commission

Chilean Mining Investments – Project Portfolio 2015 -2024 10

Table 1: Conditions for carrying out a project

Condition Project type Stage of advance SEA process Implementation

BASE Any Execution RCA approved Within the period

RCA approved or in Any Execution suspended Within the period judicial claims

PROBABLE Any Feasibility RCA approved Within the period

Reposition or expansion Feasibility EIA or DIA in process Within the period

Reposition or expansion Feasibility suspended EIA or DIA in process Within the period

Reposition or expansion Feasibility EIA or DIA not presented Within the period

EIA or DIA in process or POSSIBLE New Feasibility Within the period not presented

Any Feasibility RCA approved Outside of the period

EIA or DIA in process or Reposition or expansion Feasibility Outside of the period not presented

Any Feasibility suspended Any Outside of the period

EIA or DIA in process or POTENTIAL New Feasibility Outside of the period not presented

Any Pre-Feasibility Any Any Source: Prepared by COCHILCO The attributes of a project are associated to their type, the stage of advance they are in, the status of the processing before the SEA, and the estimated date of implementation. The explanation of each is as follows:

2.2.2. Project type

This attribute gives information about the degrees of certainty of the realization of an investment project, as it relates to the strategic purpose of the Company and the lesser to higher complexities they face for the implementation to be carried out. The categories are as follows: a) Replacement projects: Those wherein the investment is to maintain the productive capacity of a current operation (brownfield) with new mining developments, to deal with a decline in ore grades and/or depletion of sectors being mined. This allows the Company to prolong the lifespan of the site and the use of the installations. b) Expansion projects: Those which seek to enlarge the current operational capacity (brownfield), with the purpose of increasing the production scale and diminishing the unitary costs, especially due to a decline in ore grades of the mining resources to be exploited. c) New projects: Those located at a new deposit (greenfield), and have to begin everything: the environmental and sector permissions, develop infrastructure, and settle into a new

Chilean Copper Commission

Chilean Mining Investments – Project Portfolio 2015 -2024 11

location. It also includes projects in current operations (brownfield), which contemplate a complete change in the productive process (For example: from leaching to concentration), which implies a practically new development of the site.

2.2.3. Stage of advance

It is possible to estimate that to the degree that a project advances the certainty that it will be carried out increases. Therefore the projects have been categorized, according to the stage they are in: a) In Execution: The investment has been approved as well as has the corresponding permissions for it to be carried out. It is already in one of the detailed engineering or construction stages from the beginning to the implementation. b) Feasibility Assessment: Those which have already begun the feasibility studies and those of environmental evaluation (EIA or DIA) or they may already have been finished, but the final decision approving the investment has not been made. c) In Pre-feasibility Assessment: Those which are in the initial stage of pre-feasibility studies until the decision is made to continue to the following stage. Most of the projects follow a normal course, notwithstanding the modifications which are seen fit to introduce, however, the advancement of a project may be affected by some type of suspension, be it from internal situations or those outside of the company’s control. Upon suspension, the project stops advancing and in some cases will return to the previous stage to redo the studies and thereby resolver the complications which have arisen be they internal or external.

2.2.4. Processing before the Environmental Evaluation Service (SEA)

No project may be carried out without having the Environmental Qualification Resolution (RCA) approved, which occurs after an exhaustive technical-administrative process which includes civic participation, which is submitted to the declaration or the studies of the corresponding environmental evaluation. Therefore, three stages are shown, from most to least certainty: a) RCA approved, b) EIA or DIA in process c) EIA or DIA nor presented

2.2.5. Implementation time frame

The level of certainty of the background information also depends on the proximity or length of time from the date set for the implementation. The following ranges indicate a greater to lesser certainty: a) Within the period: Date within the period of analysis, or within the five-year period, b) Outside of the period or Long-term: Date after the period of analysis, or outside of the five- year period.

Chilean Copper Commission

Chilean Mining Investments – Project Portfolio 2015 -2024 12

2.3. The investments of Codelco and their information sources

The information sources about the investments projected by Codelco are based on public information given by the corporation on their webpage, in presentations from the board of directors, and are compiled primarily on the whole of information available from their Business and Development Plan, and other official information of the Company received regularly by the Direction of Evaluation of Investments and Strategic Management (DEIGE) of Cochilco, which assist in supplying a better estimate. This information is to be understood as being only a prospective tool and does not bind the public entities which would intervene in the evaluation of the investment projects, which may or may not be considered in the projection2. The investments considered by Codelco, are those which are contemplated in the 2015 Business and Development Plan (PND 2015), justified as development projects or to increase the information necessary for future developments. The development projects are directly related with the productive future of the divisions and should meet profitability norms to be approved. Of these are highlighted: a) Structural projects: a select group of the development projects conceived to take an integral advantage of the mineral resources, and constitute the base for the development of the corporation in the long term. The report of each of these projects gives explicit background information of the characteristics and investment amounts for the implementation stage. b) Other developmental projects: the investment portfolio of Codelco contains diverse projects with more temporary or short term goals, whose execution are essential for the continuity of operations in the productive divisions, considering them to complement that which has been planned for the structural projects. In this report the global background of the investment amounts is considered for this concept. Furthermore, Codelco justifies as informational projects those which allow them to acquire new and relevant information for corporative development, but which are not broken down under a particular investment project. Within this concept, the investments are grouped in studies for future developmental projects (pre-feasibility, feasibility, environmental evaluation, etc.), the investment in basic and generative exploration, and investments in I&D. Given the diversity of these purposes, only a broad background of the financing requirements considered for this concept is given.

2 Before an investment can be confirmed, it is required that an “Authorization of Investment Projects” be carried out, during the evaluation of which the Chilean Copper Commission and the Social Development Department work together. It does not include those expenses which CODELCO treats as investments (Differed expenses and others) for which the aforementioned authorization is not required. The fact that they are identified in the 2014 PND does not necessarily mean that they have the established investment authorization which is required by the applicable regulations and does not bind the entities mentioned therein.

Chilean Copper Commission

Chilean Mining Investments – Project Portfolio 2015 -2024 13

Among the projects included in this report the investments from the 2014 PND are not considered which are justified with other objectives, such as the replacement of equipment, refurbishing of installations, decontamination projects, workplace safety and well-being, even though they also require an API to be carried out. This exclusion meets the purpose of making Codelco´s information comparable with the information for private investments, as this type of information from the privately owned companies is not available. Also excluded are those corporate investment which, for their nature, do not require an API and which escape being covered in the present report. However it has been found pertinent to consider the investments of Codelco in companies intending to build metallurgic plants for by-product processing, and thereby obtain final products of a higher value3. This type of investment is excluded in Codelco´s investment total, and as such are consigned as “Metallurgic Plants” in copper mining.

2.4. Investment in private mining and information sources

The information about private mining projects is gathered principally from the announcements made by the companies through the media (company web pages, newspapers, articles in specialized magazines, etc.) and through their presentations to the environmental evaluation department. It includes all of the projects which have begun construction. In the case of the projects which are still in the Assessment phase the advancement has been reviewed and investment predictions have been updated, as well as implementation date and estimated production profiles, with the most recent public information. This implies that at least the following updates are made: a) Identification of the project titleholder for projects which have changed hands. b) Production capacity and types of products of interest. c) Investment amounts, implementation date, and execution order of events. d) Inclusion of new projects. e) Elimination of projects which were recently implemented. f) New requirements, such as the incorporation of the usage of sea water, be it directly or desalinized. With respects to the investment amounts, it is assumed that the projects reflect principally the execution stage, notwithstanding that several of them may include prior investments in the Assessment phase.

3 MOLYB Ltda. is an affiliate to produce molybdenum trioxide from molybdenite. Similarly, PLANTA RECUPERADORA DE METALES, (60% LS NIKKO of Korea and 40% of Codelco), is a company which processes anodic slime to recuperate gold, silver, and other noble minerals.

Chilean Copper Commission

Chilean Mining Investments – Project Portfolio 2015 -2024 14

Due to the fact that generally only a general investment amount is known a year prior to the implementation date, the yearly distribution of the investment is estimated by assuming tentative timelines for project development, based primarily in the information given in the presentations to the environmental evaluation system or by empirical estimates of how similar projects are developed chronologically. It is worth noting that in the cases of projects which are lacking precise public data for the implementation year, Cochilco has estimated it based on the context of the available data, which does not bind the companies in any way.

2.5. Methodological criteria for estimating the implementation date

Diverse circumstances either internal and/or external may affect the development of the projects. External factors refer to the necessary of: securing the electrical supply at a lower amount than the prevailing costs, fine tuning of the environmental impact Assessment and/or obtaining permits to build infrastructure as required for the project. Furthermore, internal factors refer to the synchronization of the project with the global strategy of the company, acquiring financing, and the need of improving the cost indicators considered for investment and/or operation as determined in the project engineering studies, as well as others. In the instance of a lack of public data about the implementation date of a given project, COCHILCO applies the following methodological criteria: a) A year of delay is considered if the project is only affected by external factors, notwithstanding that the company carries out studies to improve the Feasibility Assessment considering the resolution of the pending topics, which could mean minor modifications in the Assessment. b) Two years of delay are considered if the project requires reworking to take into account the pre-feasibility or Feasibility studies, a normal time frame for this type of studies to be carried out.

In the case that there is not sufficient background information to estimate a clear implementation date for the initiatives, these are removed from the portfolio as “restructuring projects.”

2.6. Estimating the production capacity of copper mines

The maximum potential copper production capacity corresponds to the sum of the estimated individual maximum production capacity of each profile for the current mining operations which produce copper concentrates and/or SxEw cathodes, as those which correspond to the new copper projects contemplated in the present investment portfolio which will be implemented within the next decade. The figures are expressed in tons of fine copper. The future profiles of the current operations are projected over the base of the recent productive behavior and the estimate of the evolution of the mining-metallurgic parameters (ore grade and

Chilean Copper Commission

Chilean Mining Investments – Project Portfolio 2015 -2024 15

recovery capacity of the concentrating plants or the consumption of rates in acids in hydrometallurgical operations, considering maximum treatment profiles and they do not contemplate usage problems of the processing plant, all of which are according to the information which is available to Cochilco, considering a continuous operation of 360 days per year. At the same time, the projected project profiles for the projects are based in the maximum treatment capacity of the minerals described by the companies for a continuous operation of 360 days per year, and the background of the mining-metallurgical parameters which are expected for future operations. As the projects are assigned distinct materialization conditions (base, probable, possible, and potential), the production profiles are broken down according to these degrees, indicating therein the levels of certainty from most to least. For this reason the projected amounts should be understood as an estimated potential maximum capacity, beginning in the year of the publication of the present report, according to the available background information. Included as referential data is the real production registered the year after the publication of this update. It is worth noting that the production projection horizon is up to two years after the last year of the implementation which is registered in this report.

3.1. Project conditionality

Every mining initiative may be affected by certain variables which cause changes in the planned timeline, these are usually the stage of advancement in the construction or studies, obtaining permission, be it environmental or sectoral, financial strength of the Operating companies, among others. Based on this information it is possible to establish the conditions: base, probable, possible, and potential, based on the greater or less amount of certainty of which the project will come about in the time and with the aforementioned variables4. Figure 1 shows the investment distribution according to the condition, while table 3 shows how the investment is distributed per mining sector and project condition.

Therefore the investment portfolio for 2015-2024 corresponds to 42 initiatives, broken down into 31 copper mining projects, valued in US$ 67,035 million, and 11 projects belonging to gold, silver, iron, and industrial mineral mining, for a total of US$ 10,255 million.

Of this total, we will initially analyze the projects with the greatest probability of being carried out within the time frame indicated by the proprietary mining companies, which correspond to those projects in the base and probable conditions, being 23 initiatives valued in US$ 29,845 million:

- 13 initiatives are in base condition, with an investment of US$ 21,139 million, wherein CODELCO has a 63.1% participation rate of the investments in this condition. - 10 projects in a probable condition, with an investment of US$ 10,206 million, where gold and silver mining make up 43.6% of the total investment.

The second group, projects in the possible and potential category, correspond to those initiatives with a lesser probability of materializing within the time frame established by the owners as well as being those more likely to be affected by changes in market conditions, being the equivalent of 18 initiatives valued in US$ 45,945 million:

- 13 in the possible condition, valued in US$27,464 million, wherein CODELCO has a 48% participation in the investment total. - Five initiatives in the potential condition, with an investment total of US$ 18,481 million, wherein the large private copper mining has 82% participation.

Due to the complex characteristics and ease of being affected by the variables described at the beginning of this chapter, this last group requires more attention so that in the right time they may be implemented within the institutional framework of the country.

To better analyze the variables involved up to the moment of defining the condition of the projects in this registry, following is shown the investment distribution of the projects with regards to their stage of advancement and of processing before the Environmental Evaluation Service.

Source: Prepared by COCHILCO, based on information for each project taken from public sources Upon closer observation of the investment details, it can be determined that the replacement of the productive capacity corresponds to 21% of the total investment with 12 initiatives, wherein projects y CODELCO make up 79% of this segment. Furthermore, the expansion of operations which

5 See subchapter 2.2.2, “Project type”

Chilean Copper Commission

Chilean Mining Investments – Project Portfolio 2015 -2024 21

are currently in production reaches 21.3% of the total inversion in the portfolio with only eight projects, wherein CODELCO again is relevant with 55.9% of this segment. In summary, the brownfield investments of the project portfolio, replacement and expansion of current operations reaches 42.3% of the investment portfolio with CODELCO as the principal investor.

Similarly, 22 of the 42 projects considered in the investment portfolio for 2015-2024, making up 57.7% of the portfolio´s value, correspond to new projects presented by mining companies operating in the country as well as by 10 companies who would like to enter the Chilean mining market with the new projects. The principal intention of the new companies and their projects are_ one for large copper mining, one for medium copper mining, three in gold mining, two in iron, two in industrial minerals, and one metallurgical plant. These 10 initiatives make up US$ 7,438 million, or 9.6% of the total portfolio value.

3.3. Regional Investment

The third look at the mining project portfolio is that of the regional distribution of the investment, in copper mining as well as gold, silver, iron compounds, and industrial minerals, as shown in figure 3.

Source: Prepared by COCHILCO, based on information for each project taken from public sources Copper mining, with 31 projects, makes up 86.7% of the total investments in the portfolio. Most of these are found in Antofagasta, which, with 13 projects receives 42.7% of the total investment, of which 8 are in base condition and only one in potential.

In second place is the , with 6 initiatives which make up 14.4% of the total registry. This region is the one which was most affected with respect to the previous version of the investment register, due to the fact that a large percentage of the projects are in a potential condition. In the investment portfolio for 2015, Atacama has 3 initiatives in the potential condition which make up 70.8% of the total investment in copper projects in the region.

In third place we find the Valparaiso region, which receives 10.5% of the total investment in the project portfolio, specifically the CODELCO projects “Nueva Andina Phase II” and “Mine-Plant Transfer”, both from the Andina Division.

Sharing fourth places are the regions of Tarapacá and O´Higgins, each with 8.1% of the investment portfolio, with initiatives coming from companies such as Teck and BHP Billiton in Tarapacá and with the projects from El Teniente Division of CODELCO and of Valle Central of Amerigo Resources in the case of the O´Higgins region.

In Coquimbo two iron projects are being planned, one of which is on a large scale and plans to coproduce copper, which is the case of the “Dominga” project by Andes Iron, while in Antofagasta there are two initiatives to produce industrial minerals, one of which corresponds to a iodine and nitrate project, carried out by Chilean investors in the region, named “Arbiodo”.

3.4. Investment by country of origin

An interesting perspective of the investments to be carried out within the next decade is to consider the nationality of the owners of the operating companies of the projects, as well as those which only invest in the new initiatives by participating as a primary partner. Figure 4 shows the total investment in the portfolio, according to country of origin.

Investments come from 8 countries, led by Chile with 60% of total participation, coming from companies such as Codelco and Antofagasta Minerals in state and private copper mining, Pucobre and Copec in medium mining, as well as distinct international investments in gold, iron, and industrial ore mining. In second place we find Canada, with a 21.4% participation, from emblematic companies such as Teck Resources, Lundin Mining (who just acquired Candelaria), Kinross, Capstone and the Santo Domingo project, Barrick Gold and other companies focused on investing in medium copper mining and that of industrial minerals.

For a more detailed account, in Table 9 the distribution of investments in copper mine is shown for each country and the total participation in the investment in mining is considered in the registry, all contrasted with the conditionality of the investments.

4. Estimation of the yearly investment distribution in the project portfolio

The estimation of the investment flow in the 2015-2024 project portfolio allows for the observation of the short and medium term progress in the mining investment, in the amount that emerged before 2015, US$ 15,415 million, which corresponds to 19.9% of the current portfolio, the investment to be obtained during the next five-year period from 2015-2019 of US$44,894 million, equaling 58.1% of the portfolio, and the estimate of the remaining amount to be invested in the 2020-2024 period in those projects whose implementation date is set for this time frame, whose investment amount reaches US$16,981 million, equaling 22% of the investment portfolio. Figure 5 graphs the yearly investment distribution in copper mining, and of the other minerals in the 2015 to 2024 period, separated by those already obtained, the yearly amounts for the 2015-2019 period, and finally the remnant to be invested after 2019.

Source: Prepared by COCHILCO, based on information for each project taken from public sources Discounting the US$ 10,800 million invested before 2015, the investment with possibilities of implementation within the 2015 and 2024 period in copper mining reaches US$ 56,200 million, of which US$ 39.9 million will be reached in the five year period from 2015 - 2019. Analyzing the initiatives with the greatest probability of development within the timeframes estimated by their owners, these corresponds to 38% of the investment to be implemented within the next five years. Of this group, the projects in base condition make up 25.4% of the investment to be obtained between 2015 and 2019, with a yearly average of 2.28 thousand million USD, leaving an investment remained of less than one thousand million for after 2019, while the initiatives in a

probable condition only make up a yearly average of around US$ 1.06 thousand million, which corresponds to just 7% of the financing to be obtained in the short term, specifically between 2015 and 2018. Conversely, the projects with a lesser probability of being implemented within the proposed timeframes correspond to 62% of the investment between 2015 and 2019, leaving a remnant of almost US$ 16 thousand million for after 2019. In this group, the projects in possible condition correspond to 34% of the investment in the five year period, contributing a yearly average of US$ 2.7 thousand million, leaving a remnant of US$ 8.04 thousand million for later execution. Furthermore, and unlike the previous register wherein the potential group made up the greatest investment to be implemented in the five year period, this year these projects reach just 28% of the total estimated for the next five years, supplying an average of US$ 1.99 thousand million, and leaving an investment remnant for the 2020-2024 period of around US$ 7.95 thousand million dollars.

5. Estimation of the copper production capacity in Chile through 20266

One of the most important effects coming from the mining investment portfolio is the increase in the maximum production capacity, which translates to an increase in supply for the international market. Following is an estimate of the maximum copper production capacity which Chile could reach by 2026, as a result of the work in the current Operations and the contributions which will be added as the new copper projects are implemented.

5.1. Maximum copper mining capacity in Chile

The maximum productive potential of copper mining in Chile is summarized in Table 13, which indicates the yearly information from 2015 to 2026, broken down into operations and projects according to their conditionality, as an indicator of the degree of reliability of this information. The real production in 2014 is included as a means of reference and comparison. Additionally, the percentage of yearly variation in the maximum capacity of total production is indicated. Considering a horizon of 20267, Chile has the potential of reaching a copper production capacity of 7.56 million tons of copper, a 31.6% above the production registered in 2014, if all of the planned projects are carried out according to their timelines. The maximum production would be registered for this period during 2024, wherein the copper production would reach approximately 7.84 million tons, 36.3% over 2014 production.

This projection considers the natural declination in production of the current operations in 1.94 million tons, for which the greatest contribution corresponds to the impact in the investment in the projects, which depend on distinct factors internally as well as externally to reach the productive goals, which is determined through the conditionality of the projects. The following graph shows how the copper production will evolve and the growing importance of the contribution of the projects, to increase national productive capacity according to the condition of these.

Source: Prepared by COCHILCO In each table there is an opposing trend. While the production capacity in concentrates increments by 2.84 million tons by 2026, a 70.9% increase from 2014, the SxEw cathodes may decrease by 1.03 million tons, registering a 55.7% decrease from the same year.

5.1.1. Analysis of hydrometallurgy production

The hydrometallurgical processing of copper into SxEw cathodes shows in the last decade strong signs of decline since its peak in 2009, when it reached 2.12 million tons. The production of SxEw cathodes will be maintained at about 1.8 million tons until 2017, to then decline rapidly by a yearly average rate of 7.7% in the following ten years, reaching a production loss of 1.03 million tons of SxEw cathodes (figure 6). This decrease in SxEw cathode production is due mainly to the depletion of leachable resources and the closing of some copper sites towards the end of the next decade, for example, Collahuasi, Sagasca, Quebrada Blanca, Mantos Blancos, Michilla, Las Cenizas, Franke, Mantoverde and Carmen de . Likewise, it is observed that some of the operations of CODELCO, such as

Chilean Copper Commission

Chilean Mining Investments – Project Portfolio 2015 -2024 33

Chuquicamata (Hidrosur), Radomiro Tomic and Salvador, will reduce their production due to the depletion of leachable resources. With respect to the hydrometallurgy projects considered in this portfolio, these principally correspond to replacement projects and of marginal expansions of current operations, and of four new projects: El Espino, Diego de Almagro and the production of oxides coming from the operations of Distrito Centinela, by Antofagasta Minerals, and of Sierra Gorda, property of KGHM. There are not currently any potential projects for the hydrometallurgy line.

This operational decrease has a direct effect in a lesser demand for sulphuric acid, which will cause a change in the sulphuric acid market in Chile from the condition of structural deficit to an incipient condition of excess by the year 2019. It is worth mentioning that the structural change in the sulphuric market will have negative implications in the importation and exportation structure of this good in the country, as an excess would force producers to export the excess acid, with the following negative implication in the prices of this good. Another impact is the closing of several solvent or electro-winning extraction plants, with no alternative use.

5.1.2. Analysis of concentrate production

The project portfolio for 2015-2024 reaffirms that which has been observed in the past few years: the structural change in copper production turns toward copper concentrate production, due to diverse factors such as the geologic conditions of the country, the production changes from old hydrometallurgical operations, etc. This will cause an increase in the maximum production capacity of copper concentrate by 2.84 million tons of fine copper per year by 2026. With this the projected decline will be surpassed from the current operations, without whose projects in development, would decrease production by 788 thousand tons of fine copper with respects to 2014. This substantial increase in production which comes from the concentrate line has strong repercussions in two important aspects of the mining politics in general, which are the increase of the exportable supply of concentrates, without increasing the current production of ER cathodes, and the structural increase of costs in Chilean mining coming from the levels of mineral processing which this type of processing increase brings.

a) Exportable concentrate offer from Chile In 2014 2.55 million tons of copper concentrate were exported, equaling 65.3% of the concentrate production of the country, the rest should be understood to have been consumed in the Chilean foundries. Even though the production of the foundries reached 1.36 million tons of fine copper in 2014, previous years reached levels around 1.56 million tons of fine copper, which means that there

Chilean Copper Commission

Chilean Mining Investments – Project Portfolio 2015 -2024 35

is the capacity of treating the equivalent of 1.6 million tons of fine copper content in the feeder concentrates, due to the capacity expansion projects not being considered for the national foundries9. Toward 2026, the maximum copper production capacity in concentrates will reach 6.75 million tons, reaching 89% of the national copper production participation. However, under the premise that no FURE projects were to exist in the country, this increase in concentrate production would imply that the potential exportation of concentrates would reach 5.2 million tons, or76.9% of the total Chilean concentrate production.

Similarly, the volume of concentrates for exportation would surpass the current8.67 million tons to almost double by 2026, reaching 17.26 million tons.

Source: Prepared by COCHILCO This strong growth in concentrate production could affect the position of the exporters in the negotiations for the costs of treatment and refining, affecting the liquid value of the return, and the tributary utilities of the companies, leaving Chile with a lesser participation in the refined copper business on a worldwide level. Another problem related with this increase in concentrate production is the production of tailings coming from the concentrating plants. Therefore it is estimated that if during 2014 563.5 Mt of tailings were produced, by 2026 an increase of 121.8% will produced more per year, reaching 1,249.7 Mt of tailings (figure 10).

Greater consumption intensity per unit of copper recovered. c. Greater consumption of water and other inputs depending more on the volume of the material to be treated than the copper content.

Furthermore, several of the concentrate projects are considering the use of sea water, with or without desalination, as well as the impulsion system to the place of operations. For this concept the capital costs would also rise for the required installations and the operation, because of the electricity consumed. This last also requires a clear policy to define the correct manner to introduce this new “hydrological market” in the country. In summary, if currently 10,849 tpd are produced of fine copper concentrate, as a product of the processing of 1.60 Mtpd of tailings (amounts from 2014), the copper mining project portfolio for 2015-2024 will increase the fine copper concentrate to 18,741 tpd, the product of the processing of around 3.54 Mtpd of minerals in the concentration plants, which will generate around 3.47 Mtpd of tailings toward 2026. This signifies an increase in daily treatment and tailings generation of close to 121% only to increase the daily copper production by 32%.

5.2. Maximum production capacity of copper mines per region

As well as observing the global behavior of copper production in the country, it is necessary to look at how it is manifested on a regional level, where the investment process has an economic impact which is prolonged after the product of the investment is transformed into operations. The magnitude and use of the maximum production capacity is what generates the long term effect on the activities directly related with the mining, and very importantly, in the diversity of the activities indirectly provided of goods and services which is very relevant to the region where it is carried out. The following tables show the production capacity estimates of copper mining corresponding to each productive region, breaking them down for the respective profiles of maximum concentrates and SxEw cathodes.

Even though the production of concentrates will increase by 100.6%, this will only create an net increase of 50.7%, affected by the loss seen of 778.7 thousand tons of SxEw cathodes, equaling -52.3% of the production from 2014. Atacama will maintain the second place in copper production, with a high level of production increase which will be raised specifically by an increase of almost 200%, coming not only from the copper production initiatives, but also from the coproduction of the projects of gold and iron mining, which would leave available a capacity of 980 thousand tons of fine copper, over the 430.8 thousand tons produced in 2014. As in the Antofagasta region, the productive increase in concentrate will help to reduce the productive loss coming from the hydrometallurgical operations, which will fall by -56.3% by 2026. Furthermore, this region is affected by situations which will slow the development of the projects, even more if we consider that the greater part of the projects from this region have

a lesser probability of implementation within the time frames estimated by the companies (possible and potential). Valparaiso, in this report, displaces Tarapacá as the third most important region, for two important motives. The first is due to Tarapacá suffering a strong decline in production towards 2024 where four of the most important hydrometallurgical operations, Cerro Colorado, Quebrada Blanca, Collahuasi, and Sagasca, stop operating, thereby losing almost 163 thousand tons of fine copper, some of which are slightly recovered by the sulphuric operations of Collahuasi and the Quebrada Blanca Hipógeno project. Tarapacá, the third most important, bases the productive development on the potential expansion of Collahuasi, however if it is not completed within the time frame, the region will see the copper production capacity drastically reduced. The second reason that it has passed the third place of productive growth to the region of Valparaíso is the implementation within the period of the expansion of Andina, with which it will increase the production level from 290.2 thousand tons of fine copper registered in 2014 to 669.5 thousand tons by 2026, creating an increase of 130.7%, which is the greatest regional increase during the period, and slightly higher than the increase of Atacama. Coquimbo will remain in fifth place, with contributions from El Espino, Domingo and the expansion Marginal of Los Pelambres. Likewise, O´Higgins will remain in the sixth place for growth, due to the increase in production foreseen with the implementation of the “Nuevo Nivel Mina” in El Teniente, and the Metropolitan region remains with a relatively stable production because of the contribution to the Los Bronces -- Phase VII project. Finally we can deduce that the mining investment will diminish in the northern zone of the country, and stepping up in the center-south zone with the following offsetting of the productive increases to this zone.

5.3. Global estimate of production capacity of other minerals

The estimate of the contribution to the maximum production capacity thought 2026 for mineral substances such as gold, silver, molybdenum, iron and industrial minerals will only be done on a global level, and not yearly, different from what has been shown previously in the projections of copper production. For gold, molybdenum, and iron, the maximum production capacity is shown, according to the background information of the compiled projects, comparing the current situation with respects to the possible scenario toward 2026. In the case of silver, for being a co-product which depends on the gold mining activities, only the maximum estimated production of the country will be seen for each project, and the possible contribution to the maximum production capacity of the country once the projects being their operations. For industrial minerals only the contributions for each project considered in this portfolio will be shown.

The contribution of gold mining in Chile comes from two sources: directly from gold mining (primary production) and as a co-product of copper mining (secondary production). Thanks to the contribution of the registered projects, through 2026 the maximum production capacity of thus metal could reach 80.5 tons of gold content, a 75% increase over the 46 tons registered in 2014. In the case of silver, the projects in this report will reach some 1,495 tpa of silver by 2026 over the current production, which in 2014 reached 1.572 tons of silver.

5.3.2. Molybdenum production capacity

Molybdenum production in the country is a by-product of copper mining. In the last 10 years between 33.7 thousand and 48.8 thousand tpa of Mo concentrate has been recovered as

molybdenite (MoS2) wherein in 2014 reached the maximum production of the last decade. Some copper projects in the investment portfolio also contemplate the reclaiming of molybdenum:

Chilean Copper Commission

Chilean Mining Investments – Project Portfolio 2015 -2024 45

a) New projects which consider recovering molybdenum as a co-product of the future copper concentrate production. For this effect the projects considered are: Actualización de Esperanza, Spence Growth Project, Quebrada Blanca Fase II and Relincho. b) Initiatives which seek to expand or replace current concentrate production, and therefore, will permit to maintain the stable current production of molybdenum and to supply new production. Among the initiatives associated with this type of project are the structured projects of CODELCO. The total contribution of the aforementioned projects is shown in table 20.

Source: Prepared by COCHILCO Therefore it is estimated that by 2026 the maximum capacity for molybdenum recovery will reach 95.6 thousand tpa, a 96% growth rate with respects to the production from 2014, which implies an average yearly growth rate of 5.3% until 2026.

5.3.3. Iron production capacity

The production level of iron mining reached 18.87 Mt of iron ore in 2014, equaling approximately 11.1 Mt of fine Fe content.10 The primary iron production or co-production projects in this update will contribute 18.8 Mt of iron ore by 2026, making approximately 11.9 Mt of fine content iron. The details of the estimated contribution of the projects is shown in table 21.

10 Iron products have an iron content of between 58 and 65%.

Source: Prepared by COCHILCO. To summarize, due to the project portfolio with direct iron production, or associated co-production, the maximum production of the country by 2026 will be situated around 33.3 Mt of iron ore, which reflects an 80% growth with respects to that registered in 2014.

5.3.4. Industrial minerals

Among the investment projects in the area of saltpeter, is found the Pampa Blanca Expansion by SQM, displaced in the previous time frame by two years, and the Arbiodo Project by Ingenieros Asesores Ltda., linked to national capitals, which is in the process of restructuring the EIA presented in March of 2015 and then withdrawn by the company. The first plans to increase the production of iodide, by SQM to 10,000tpa of iodine equivalent and produce around 1,293,000 tpa of NaNO3. The second initiative seeks to produce around 2,700 tpa of iodine and 400,000 tpa of nitrates, including 20,000 tpa of boric acid.

In another area of non-metal mining, White Mountain Titanium with the Cerro Blanco project will produce titanium dioxide (TiO2) at an estimated capacity of 200 ktpa of concentrate (95% TiO2), by 2016. It is worth noting that this project is only waiting for the investment decision, as in May of 2015 it received the approved RCA from the Environmental Evaluation Service.

6. Comparison of the project portfolios in 2015 and 2014

The investment project portfolio in Chilean mining updated in July of 2015 contemplates 41 initiatives, versus the 53 included in the project portfolio informed in July of 201411, 12 but with a smaller investment estimated in 29,062 million dollars.

The changes registered in the condition of implementation, timeframe and value observed in the 2015 portfolio with respects to the previous correspond principally to the following: a) The implementation of 6 projects considered in the 2014 portfolio, valued in US$ 7,587 million, which are excluded in the new portfolio. b) Ten initiatives were removed from the portfolio for restructuring or because the owning companies are in the process of adjusting their assets, for which there is no clear date when they are going to reinitiate the studies or the investment decision, which reach an estimated investment in 2014 of US$ 28,223 million. Of these projects only El Morro was affected by issues related with Convenio 169 of the OIT, which translated into the approved RCA being annulled and a return to the pre-feasibility stage of engineering studies. c) Five new projects were incorporated into the portfolio with a value of US$ 5,580 million. Of these, four correspond to copper mining, one of which is an expansion of Los Bronces, a renewal project in Quebrada Blanca, which will allow for a future project of Sulphur, and the new BHP Billiton project which plans to extend the lifespan of the Spence site through a Sulphur line and the expansion of the Sulphur line and a new oxides line for the new operations at Sierra Gorda, by KGHM. The fifth project belongs to industrial minerals (Arbiodo). d) There are 10 projects which did not see any changes with respects to the report from 2014, evaluated in US$ 11,103 million. e) The Escondida OGP I is the only project which only announced a modification in the investment amount, from US$ 3,838 million estimated in 2014 to US$ 4,199 million, which is a net increase of 361 million dollars. f) Furthermore for eight projects the companies have announced a delay in the previous implementation date by one to three years, notwithstanding there not being a change in the conditions of realization, nor in the budgeted investment amount, which reaches US$ 18,416 million.

11 Considering “Other development projects” and “Information projects” of Codelco in both portfolios.

g) Finally, sixteen initiatives show modifications in their condition of materialization, value and/or timeframes for implementation. Positive cases include Encuentro Oxidos and Modifications El Tesoro from Antofagasta Minerals, which passed on to base condition, as did Chuquicamata Subterranea, however this last suffered a year´s delay with respect to the previous report. The changes in these initiatives generated an increase in the net investment by US$ 2,709 million.

The projects which are in this position are duly marked in tables 22 and 23, wherein the projects are consigned to the list of projects in the portfolio with the variations registered with regards to the previous year.

Furthermore, it is POSSIBLE to see the most important global changes between both portfolios according to the implementation condition and mining type, an association between both previous scenarios, and a regional comparison of the investment (tables 24, 25, 26 y 27).

In the previous table it is seen that the portfolio with the highest probability of completion within the timeline estimated by the owning companies (base + probable) remain almost stable, in number of investments as well as in investment amount (increase in US$ 1,628 million), however, it changes from having a 28.3% participation of the total portfolio in 2014 to being 40.6% of the portfolio in 2015. It is possible to take from this comparison that two initiatives passed from probably to base, one initiative in probable condition was removed from the portfolio for restructuring, and one is added to the probable condition, specifically the Sierra Gorda expansion, and five advance from the possible and potential conditions up to probable.

On the contrary, those initiatives with a lesser probability of maintaining the advancement terms indicated by their owners and investors (possible and potential) diminished by almost 30%, due in part to the removal of 9 initiatives from the potential category for restructuring13 and the change of five projects to probable condition. However, to this group two new initiatives were added, Arbiodo and Spence Growth Project as possible. This shows that the weakness of the investment portfolio is in this group.

Table 25 shows the comparison according to mining type, wherein it is observed that the project portfolio for copper is reduced by almost 17% due in part to the removal of the Escondida Nueva Pila de Lixiviación and Sierra Gorda, both of which have been in operation since the first trimester of 2014, mainly because of the removal from the 2014-2024 portfolio the expansion initiatives of Collahuasi and Los Pelambres.

It is to be noted that the sector most affected is gold and silver mining, where the investment portfolio was reduced by 68%, due to the removal of five initiatives, among which Cerro Casale and El Morro stand out, the first affected indirectly by the problems which Barrick has had to deal with to carry out Pascua Lama, while the second is due to problems related with communities and investment reducing policies which the company GoldCorp has had on a worldwide level. The comparison between the investment destination and the condition of the projects may be seen in table 26.

On a national level, the northern zone15 is that which has seen the greatest decline in investment, with 31.5% less than registered in the previous registry. Likewise, on a regional level, the regions with the greatest investment declines are the region of Coquimbo (-58.8%), Tarapacá (-54.2%) and Atacama (-44.7%). However the first two decreases in investment are due to the removal of an important project in each region (Ampliación IV Los Pelambres and Collahuasi Fase II, respectively), while the investment decline in the Atacama region is due to the removal of eight initiatives, which shows the difficulties that exist in the region with respects to the materialization of projects (table 27).

7. Conclusions

Chile, like the rest of the world, has been greatly affected by the weakening of the price of commodities, which has made the materialization or advance of mining initiatives difficult in the past few years. Likewise, mining has been affected by a new treatment coming from the communities wherein the projects will be installed. Currently the portfolio of mining projects to be carried out within the next decade consists of 41 initiatives which will allow Chile to maintain its worldwide leadership in copper production and increase significantly the production of gold and silver, of iron, and of some industrial minerals. The relevant elements of this portfolio are not the global value, rather the composition in terms of the number of initiatives, who is pushing them, the objectives, where they are found, and the efforts being made to carry them out. From the analysis of the background information shown in this report the following can be concluded:

 Investment origin

For the first time, CODELCO presents an investment portfolio almost equal to that coming from the private copper mines, which, beyond seeking a productive increase of the state, seeks to consolidate the sustainable development in the long term, permitting the continuity of operations for the next 30 years. This portfolio reaches US$ 28,656 million, being 43% of the copper portfolio and 37% of the total portfolio. CODELCO possesses 61% of the investments in base condition of Chilean copper mining. Only some private companies in large copper mining maintain investment plans of a similar magnitude to those of CODELCO, among which stands out Antofagasta Minerals, with the developments in Distrito Centinela in the community of Sierra Gorda, KGHM and the expansion of the new operation of Sierra Gorda, BHP Biliton with the expansion projects of Escondida and the continuity of operations in Cierro Colorado and Spence, the last with a line of sulphured minerals. Following the same example is Teck with Quebrada Blanca Hipógeno and the Relincho project in Atacama, and Freeport McMoRan, which after the sale of their assets in Atacama put all of their efforts in the El Abra Mill project. The investment in other minerals18 has been diminished with respects to the previous year, specifically with respects to the previous year, specifically to gold mining, which has fallen by 68%. The most affected is that which development potential in the Atacama region. The investments come from 8 countries, led by Chile, with a 58.9% of total participation, coming from the state and private mining. In the second place is Canada with a 21% participation, with emblematic companies such as Tech Resources, Lindin Mining, (which was just acquired by Candelaria), Barrick Gold, and other companies focused in investments in the medium copper mines

Chilean Mining Investments – Project Portfolio 2015 -2024 55 and of industrial minerals. With participation of less than 10% are countries such as Australia, the United States, Japan, the United Kingdom, Poland, China, and Korea.

 Investment purpose

On a global level, the purpose of developing greenfield initiatives reaches a 57.7% of the portfolio total with around 22 projects, being relevant for all of the classifications with exception of the investments carried out by CODELCO, being mainly brownfield. The expansion of the operations as well as that of replacing the current production are especially relevant for CODELCO, to assure its competitive position in the long term, as well as for the conditions of depletion in which some of the most emblematic sites are found. For the expansion projects 9 have been identified which make up 22.9% of the total investment, whereas for the replacement 11 projects are considered, with a 19.4% of the investment total.

 Investment Region

Antofagasta remains the principal investment destination, focused principally on copper mining, with 22.3% of the total participation in the investment portfolio. Atacama is the second investment destination, with 22.2% of the total investment participation, and is the only zone with investments in gold mining (32% of the regional investment) as well as a significant investment in copper (62% of the regional investment) as well as other minerals. Valparaíso, Tarapacá, the Metropolitana region, and O’Higgins only have copper investments, while Coquimbo has copper investments and a significant iron Project with copper coproduction.

 Investment conditionality

All mining initiatives may be affected by certain variables which affect their planned timeframe, which are mainly the stage of advancement in construction or of their studies, obtaining of permits, be it environmental or legal, financial strength of the operating companies, as well as other factors. Therefore the initiatives with the greatest probability of materializing within the timeframes indicated by the proprietary mining companies, which corresponds to the projects in base and probable condition, correspond to 24 initiatives valued in US$ 31,345 million dollars. In the group of projects which are in the possible and potential categories, which correspond to those mining investments with lesser probability of being implemented within the timeframes defined by the owners are also those most susceptible to being affected by changes in market conditions, wherein we find 18 initiatives valued in US$ 45.945 million. Conversely, the projects in execution reached 27.4% of the total portfolio with 13 initiatives, while those projects in the feasibility stage correspond to 26 initiatives wherein 62.8% of the investment total is concentrated.

Chilean Mining Investments – Project Portfolio 2015 -2024 56

There are 17 initiatives making up 27.1% of the investment total which have the RCA approved as of July 2015, which indicates the existence of 6 initiatives within the next few months which could begin implementation and change their materialization condition. Likewise, 33.1% of the investment corresponds to 11 initiatives which have not received a positive environmental qualification resolution (RCA approved) for the projects presented, and 27.5% of the investment corresponds to projects who have not yet entered their respective EIA into the system.

Upon annualizing the financing coming from the investment portfolio, it is possible to identify three periods: - Investment already received, which corresponds to US$15.380 million, or 19,9% of the current portfolio, - The investment to be concreted during the next five year period, 2015-2024, US$ 44,894 million, equaling 58.1% of the portfolio, with an average yearly investment of US$ 8.979 million, - The remainder to be invested in the 2020-2024 period being those projects whose implementation date is planned for this period, whose investment reaches US$ 16.981 million, making up 22% of the investment portfolio. Among the investments to materialize during the next five year period, the group of projects in base and probable condition make up 40% of the investment, with an average rate of US$ 3,592 million. Furthermore, the group of initiatives in the possible and potential condition make up the remaining 60%, with an average yearly investment of US$ 5,386 million.

 Structural change in copper production

Considering a horizon of 2026, Chile has the potential of reaching a copper production capacity of 7.56 million tons of copper, a 31.6% increase over the production registered in 2014, if all of the planned projects are carried out according to their timeframes, the maximum production registered within this period would be reached in 2024, wherein the copper production would reach approximately 7.84 million tons, 36.3% over the 2014 production. This increase in production shows a structural change in the type of final product of the copper operations, whereas as the production capacity in concentrates were to increase by 2.84 million tons by 2026, a 72.7% increase over 2014, the SxEw cathode production would diminish by 1.03 million tons, registering a 55.7% decrease with respects to the same year. This decrease in SxEw cathodes is principally due to the exhaustion of leachable resources and of the closure of operations of some copper sites towards the end of the next decade, such as Collahuasi, Sagasca, Quebrada Blanca, Mantos Blancos, Michilla, Las Cenizas, Franke, Mantoverde and Carmen de Andacollo. Furthermore, it is observed that some of CODELCO´s operations, such as Chuquicamata (Hidrosur), Radomiro Tomic and Salvador, will reduce their production due to the depletion of leachable resources.

Chilean Mining Investments – Project Portfolio 2015 -2024 57

However, the increase of production coming from the concentration lines has repercussions on two aspects of the strategic mining area, which are: - Increase in the exportable supply of concentrates, without increasing the current production of ER cathodes: where during 2014 2.55 million tons of copper concentrate was exported, equaling 65.3% of the concentrate production of the country, by 2026 the maximum copper concentrate production should reach 6.75 million tons, reaching 89% of the national copper participation, wherein it could potentially export 5.2 million tons of concentrate, in other words, 76.9% of the Chilean copper concentrate production.

- Increase in the levels of processing and generating of tailings: if currently 10.849 tpd of fine copper concentrate is produce, as a produce of the processing of 1.60 mtpd of sulphured ore, and generate around 1.56 Mtpd of tailings (2014 amounts), the copper mining project portfolio for 2015-2024 will increase the production of fine copper concentrate to 18.741 tpd, as a product of the processing of around 3.47 Mtpd of tailings by 2026. This means an increase in daily treatment and tailings generation of around 121% to only increase daily copper production by 32%.

1.1. Structural Projects by CODELCO - www.codelco.cl

SULFUROS RADOMIRO TOMIC PHASE II (División Radomiro Tomic)

The Radomiro Tomic Sulfuros project corresponds to the option of continuing the development of the RT open pit mine, whose oxide production will fall decisively beginning in 2018, through the exploitation of the Sulphur estimated in 2,600 million tons, with an average copper grade of 0.47%. From the mining perspective this project adds new extraction phases which take advantage of the current development of the Radomiro Tomic mine, generating a total material movement of between 600,000 and 650,000 tpd, with a mineral production of 200,000 tpd. With respects to ore processing, the project proposes the construction and operation of a new concentrator plant with a 200,000 tpd capacity, with which it would be one of the largest SAG concentration plants in the country. It is estimated that the project will contribute around 350 thousand tons of fine copper annually, as well as 7 thousand tons of molybdenum concentrates. Among the most relevant aspects is the use of desalinized sea water in the processes, and beginning in 2021, the implementation of thick tailings technology, which will allow for the optimized usage and size of the tank, to recover more water and diminish the emissions of material particles, among other environmental advantages. In 2013, project finished the feasibility studies, considering reaching 200,000 tpd of processing in two stages of 100,000 tpd each: the first in 2018 and the second in 2021. Furthermore, it advanced in the acquiring the land and services which will be required to base the future installations on. In May 2013, it entered into the Environmental Impact Assessment phase of the projects, and by the end of the year was finishing the first addendum, to later obtain the sectoral permit. Currently Codelco has responded to the second addendum of the project and the Environmental Evaluation Service (SEA) is in the process of indigenous consulting within the framework of the Convenio 169 of the OIT. Resources : 3,617 Mt @ 0.46% Cu Treatment Capacity : 200 Ktpd of sulphured ore, in two stages.

Chilean Mining Investments – Project Portfolio 2015 -2024 59

Estimated Investment : MMUS$ 5,376, including the infrastructure for desalinization and impulsion of sea water, but does not include the thick tailings plant, to be built at a later time. Sea water usage : Considers a desalinization plant with inverse osmosis technology of 1,600l/s, with an estimated investment of US$ 1,500 million, included in the total project investment.

Current Status : In process of RCA approval and of sectoral permits, with time extension requested until September 2015. Beginning of construction estimated for the beginning of 2016, to finish stage 1 of the process by the end of 2018.

NEW LEVEL MINE (División Teniente)

This development will enlarge the El Teniente mine to a deeper area of the site, located in the 1,880 level, being 100m lower than the current Teniente 8, adding to this a exploitable area of 2 million square meters. This new sector contains reserves which reach 2,020 million tons and with an average copper ore grade of 0.86% and 220ppm of molybdenum. The configuration of the project contemplates the exploitation through a panel caving system, with 100% of the area preconditioned with hydraulic fracturing and a level pattern that is typical for El Teniente mine: sinking, production, ventilation, hauling, and crushing. The difference is, in this case, the mineral will be transported to the surface through a system of transportation belts to the Colón concentrator. The project will allow the level of divisional operation to reach sustained operations in the long term at 137 ktpd, extending by more than 50 years the useful lifespan of the mine beginning in 2017. Additionally it leaves the option of reaching a treatment capacity of 180 ktpd within the next decade open. It is estimated that between 2011 and 2017 the project will carry out 98,450 meters of tunnel work (horizontal development) and 3,454 meters of vertical developments: ventilation ducts and transfer shafts.

Chilean Mining Investments – Project Portfolio 2015 -2024 60

It is worth noting that the New Level Mine (Nuevo Nivel Mina) project poses an engineering design oriented to diminishing risks. At the same time, it will greatly reduce the exposure of the workers to dangerous situations , as it considers semi-automatic operations commanded in the control rooms located in the valley, more than 50 kilometers from the work site. Resources : 3,732 Mt @ 0.86% Cu Treatment capacity : 137 Ktpd of sulphured ores, with possibilities to expansion within the next decade to 180 Ktpd of sulphured ores. Estimated investment : MMUS$ 4,920 Seawater usage : Does not apply. Labor : 3,500 workers in construction stage. Condition of materialization :

Condition Project type Stage of advance SEA permit Implementation BASE Replacement Execution EIA approved 2021

Current Status : The project has passed on to a closer review, delaying the expected implementation date and increasing the investment required for development. The aforementioned is explained by greater geotechnical complexity in the access and transportation. It is expected that it will gradually start up production in 2021.

CHUQUICAMATA SUBTERRÁNEA (División Chuquicamata)

The Corporation is currently exploring the geological resources deep in the Chuquicamata deposit, whose reserves are estimated at 1.650 million tons with a .71% copper grade. The project considers the exploitation through macro blocks, using the extraction process of “block caving”, in a subterranean mine made up of four production levels; a principal access tunnel 7.5 km long, five clean air injection ramps, two air extraction spires, and many other features. Likewise it foresees an increasing production rate from 2,700 tons of ore per day at the beginning of the operation, up unto meeting the goal of 140,000 tpd nine years later, which would mean a yearly production of 366,000 tons of fine copper and 18,000 tons of fine molybdenum.

Chilean Mining Investments – Project Portfolio 2015 -2024 61

The development would coincide with the end of the useful life of the put and would send the minerals to the current concentrators of Chuquicamata. Resources : 1,728 Mt @ 0.80% Cu Treatment Capacity : Up to 140 Ktpd of sulphured mineral. Estimated investment : MMUS$ 3,816 Seawater usage : Does not apply. Labor : 3,767 in the construction phase and a maximum of 4,837 in the operational phase, once Operations reach their peak. Condition of materialization :

Condition Project type Stage of advance SEA permit Implementation BASE Replacement Execution EIA approved 2020

Current status : The first stages have been completed, currently carrying out access tunnel and transportation tasks. A gradual development of the mine is planned, with production to commence in 2020.

NUEVA ANDINA: PHASE II - EXPANSIÓN A 244 KTPD / (División Andina)

This structural project by Codelco consists in the treatment capacity expansion of the Division Andina by 150 ktpd of mineral, passing from the 94 ktpd reached in the PDA phase 1 to 244 ktpd nominal capacity. The prior is translated for the first 30 years of operation, in an additional 343 ktpa of fine copper, which would take the Division Andina to be producing around 600 ktpa of fine copper and would extend the useful lifespan of the Division until 2085. The construction or the Expansión Andina will take 6 years due its complexity and the need to build a mineral transport system through tunnels in the high mountains. The expansion considers new unitary operations of primary crushing, mineral transportation, secondary and third crushing, collective, selective and molybdenum recovery flotation plants, as well as a filtering plant with concentrate storage, for later transportation and storage in the Quintero Bay. Among the necessary equipment, this project will include the use of HGPR technology (High Pressure Grinding Roll), in the third crushing stage, with which it is hoped to lower operation costs, by around 20%, a savings which is strongly sustained by a lower specific consumption of energy, around 25%. For these operations, the project includes work in the Valparaíso region, expansion of the pit mine and mining infrastructure, of the mineral transportation system, new concentration plant and copper concentrate storage in the Bay of Quintero, as well as in the Metropolitan region the expansion of the Ovejería tailings tank (currently in operations), a new canal for the transportation of tailings, a water recirculation system from the tank, electrical transmission lines of 22kV and 33kV, a concentration duct and a filtering plant in the Montenegro area.

NUEVO TRASPASO RAJO - PLANTA / (División Andina)

The New Primary Crushing System consists in the construction of a new crushing line, which will allow the current production capacity of División Andina to be maintained, with around 92 thousand tons of mineral per day, generating around 240 thousand tons of fine copper per year, as well as 3.9 tons of molybdenum production. In accordance with the mining plans and the advance, the current feeding lines for the Don Luis crusher will be affected by the pit growth. Therefore the División Andina will require the replacement of the infrastructure which guarantees the mineral processing capacity, fitting a new space wherein a new crushing line will be installed which allows the transfer of mineral from the mine to the plant. The work contemplates the construction of a platform in the 3.500 Nodo, an avalanche protection system, the construction of a new primary crusher, the construction of the Haulage III belt tunnel, the SAG hopper distribution and feeding system, and a new secondary crushing plant. This will allow the useful life of the pit to be extended until 2033 and allow the development of the Nueva Andina Fase II. Another of the most appealing innovations of this projects consists in the installation of an avalanche control system which will allow to guard all of the installations contemplated in the area, and of course, the personnel who work there.

Current status : The project is in the investment execution stage, as initiated in mid- 2013. The construction of all of the parts of the project will take 8 years due to the climatic conditions which impede surface work during the winter months, being completely operational not before 2022.

RAJO INCA/ (División Salvador) The Rajo Inca consists in an operational continuity project of the current installations of the El Salvador Division of CODELCO, through the open pit exploitation of the Indio Muerto deposit. This project, as well as extending the useful life of Salvador for more than 30 years from the closure of the subterranean mine, contemplates the expansion of the current treatment capacity of the Division from 2022, reaching a total of 132 ktpd in 2023. The current mining plan of the Salvador Division contemplates the usage of the sulphured resources form the Inca area through subterranean mining which will be interrupted in 2018 because of the pre-stripping work having begun for the Rajo Inca project. Furthermore the area called Campamento Antiguo will exhaust its reserves in 2017. The pre-feasibility API of the Rajo Inca project has been turned in for review. This prefeasibility Assessment contemplates flexibility in the design and extraction sequence of the Rajo Inca project, being subject to controlling with a greater level of certainty in the tonnage and ore grade feeding the plant due to the high percentage of broken mineral contemplated in the operation and to reevaluate the development strategy of the mining business, analyzing the possibility of a smaller entrance to the Rajo Inca to thereby speed up the implementation date. It is to be noted that the Corporation contemplates analyzing the feasibilty of processing marginal resources (run of mine process) with the purpose of using the Sx-Ew assets of Salvador during the transition period of the Rajo Inca, a project which could supply, beginning in 2017, leachable resources of a low ore grade.

2. Large private copper mining projects

2.1. Projects of Anglo American - www.angloamerican.com

LOS BRONCSE FASE 7 (Anglo American Sur S.A.)

The Los Bronces operation considers prioritizing the use of the mineral in those sectors with the best geological information and lowest ore burden, to be able to maintain the current production levels. In this sense, the project incorporates a modification of the mining usage denominated Fase 7 of mining development. The extension of Fase 7 contemplates an estimated 44 hectare surface, which currently is used and occupied for service infrastructure of the mining operations. From the productive point of view, it is projected to extract a total of approximately 78 million tons of material, of which 42 million tons correspond to tailings and 36 tons of mineral. As a result of the prior information, it is necessary to reposition the infrastructure which will be affected by the mining development, which will bring with it the construction, fitting and relocation of buildings and other operational service infrastructure. Given the fact that the project has the objective of sustaining the current production levels, without incorporating modifications in the mineral treatment capacity of the plants, an increase in water consumption and inputs is nor projected which would pass the authorized levels of the “Desarollo Los Bronces” project. In this same sense, to carry out the project will not require new mineral processing plant infrastructure, modification of the pulp transportation system, nor of the tailings tanks. Resources : XXXXXXXX Treatment Capacity : 160 ktpd average, with a maximum of 180 ktpd. Estimated investment : MMUS$ 112 Labor : 120 in the construction phase. Seawater usage : Not considered.

2.2. Antofagasta Minerals Projects - www.antofagasta.co.uk

ANTUCOYA (Minera Antucoya Ltda.)

A deposit located at 125 km to the northeast of Antofagasta and at 45 km in a straight line from the coast, which contains proved and probable reserves of 635.8 million tons with 0.35% copper (with a cut-off grade of 0.21% Cu). The project will produce an average of 85,000 tons of copper cathodes during the first 10 years of operation, to later reach an average of 80,000 tons of cathodes per year until completing the 20 years of useful life that is estimated for the project. Antucoya will be developed as a conventional open cast mine and the mineral will be processed through dynamic leaching pits and a SXEW plant, using untreated seawater in the operations. Although it is a greenfield type project of low grade, there are a series of compensable factors; the deposit is relatively shallow and therefore the process of pre-stripping to eliminate the 35 million tons of waste is only expected to take nine months; the sterile/mineral relationship is also low, approximately 1:1; the deposit is located within a well-developed mining zone, which permits easy access to pre-existing infrastructure, including energy, water, and human resources. Toward the end of December of 2012, the development of Antucoya was suspended to allow for a review of the project due to an increase in the current and potential costs. After the positive adaptations, the construction of the project was reactivated in the second trimester of 2013, eliminating the acids plant considered in the initial project, and increasing the average production for the first 10 years. Resources : 1,208.5 Mt @ 0.30% Cu (measured, indicated, and inferred) Treatment Capacity : High grade mineral, up to 96 ktpd; ROM (Run of Mine) mineral, up to 38 ktpd. Estimated investment : MMUS$ 1,900 Labor : Between 5,000 and 7,000 in the construction phase, and 1,400 in the operation stage. Seawater usage : Provided through an impulsion system from Esperanza.

ESPERANZA UPDATE (Minera Centinela, ex Minera Esperanza)

The Esperanza mine, located 30 km from the area of Sierra Gorda, Antofagasta region, has begun an optimization process through two environmental impact declarations (DIA) presented in 2013.

Chilean Mining Investments – Project Portfolio 2015 -2024 67

The first optimization, called “Tercera Actualización Proyecto Esperanza”, with the DIA approved in May 2012, seeks to increase the availability of critical inputs (water, inhibitors and process reactive, etc.), incorporating new oxidized minerals resources in areas to later be used as dumps, and the construction of a new molybdenum processing plant. In this first optimization, the “Planta de Molibdeno” project represents the task with the greatest reach. The location of the plant is in a sector close to the collective flotation, in the Esperanza sector next to the existing concentrator plant. The process corresponds to a standard selective flotation circuit with a treatment rate of 5.5 Ktpd, with the following stages: primary flotation, cleaning flotation, filtering, drying and storage of the Molybdenum concentrate produced. The end, or “tailing” of the process corresponds to the copper-ore concentrate which will continue its processing in the current concentration plant. The second optimization, denominated “Cuarta Actualización del Proyecto Esperanza -Optimización del Proceso”, with a DIA presented in June of 2013, concentrates on the improvement of the current crushing and floating systems, with the incorporation of a secondary and tertiary crushing plant as a complement of the current processing capacity, as well as another concentrate thickener and another of tailings. Once these improvements are concreted, Esperanza will have increased the treatment capacity of the concentration plant of 12 ktpd, reaching 105 Ktpd to be treated. This increase is translated into approximately 19 Ktpa of Cu concentrate added to the current production of the operation. Furthermore, the molybdenum plant will allow the company to produce around 2 ktpa of Mo during the useful life of the current operation, substantially increasing the value chain. Of these two initiatives, “Optimización del Proceso” is the most advanced, estimating that the increase in the output of the plant to 105 Ktpd will be complete by the end of 2015. During 2013 the project´s activities were focused on the installation of the two additional tailings thickeners. With respects to the construction of the molybdenum plant, Esperanza will continue evaluating the project, which is currently in the feasibility Assessment phase. However, if it is approved, production could begin in 2016. It is to be noted that due to the restructuring of the Distrito Centinela projects, Esperanza Sur was added to the mining plan of Esperanza, increasing the operational reserves from 731.6 Mt with ore grades of 0.50% in copper, 0.011% of molybdenum, and 0.19 gpt of gold to 1,789.2 Mt with ore grades of 0.45% in copper, 0.013% of molybdenum, and 0.16 gpt of gold. This would increase the useful lifespan of the current operations in Esperanza by an additional 30 years. Resources : 3,244.7 Mt @ 0.38% Cu; 0.005% Mo; 0.12 gpt Au (measured, indicated and inferred) Treatment Capacity : 12 ktpd of additional sulphured mineral over current capacity, plus 5.5 ktpd of treatment in the molybdenum plant. Estimated investment : MM US$ 630 (“Tercera Actualización Proyecto Esperanza” MMUS$ 200; “Cuarta Actualización del Proyecto Esperanza -Optimización del Proceso” MMUS$ 430). Seawater usage : Will be maintained from the current plant. Labor : 875 workers in the construction phase and 49 in the operational phase.

MODIFICACIONES EL TESORO (Minera Centinela, ex Minera Tesoro)

The El Tesoro mine, located 25 km to the east of the area of Sierra Gorda, Antofagasta region, and with an altitude of approximately 2,300 meters above sea level, in January of 2014 presented the DIA “Continuidad operacional: Aumento de capacidad de procesamiento y modificación Planta SX”. This project has the principal objective of maintaining the production of fine copper cathodes from El Tesoro, equivalent to 110 ktpa. This will be possible, by providing the maximum benefit of their own resources, and also by processing the copper-rich solutions provided by third parties. The project is centered on four points in particular: i. Increasing the processing capacity: Consists of crushing, agglomeration, and leaching of 2,500,000 tons of minerals, preferably stick, but eventually directly from one of more of the pits being mined in the site, in a new comminution, agglomeration, and leaching plant. This increased processing capacity will allow for the partial compensation for the decrease in the ore grade of the minerals being processed. ii. Gravel leaching: generated from minerals previously leached in a dynamic pit, but which for their remaining copper content are profitable to reprocess (re-leaching) within the same pit as the existing gravel. It will be benefitted by 3,000,000 tons yearly during the rest of the useful lifespan of El Tesoro. iii. Modification of the SX Plant and processing of solutions from third parties: in this case, the SX plant will require modification, with the objective of allowing it to process solutions, in the short term, from the Encuentro Óxidos project, and in the long term, from other oxide deposits which may exist in the area. iv. Carrying out drilling surveys: through diamond drilling and reverse airflow, in an area that was previously explored within the mining properties of the current operation, specifically the area known as Llano- Paleocanal, located directly south and southeast of the Tesoro Noreste pit. In the end of July of 2014, the project was approved by the SEA, with which the carrying out of the project should have started in the end of August 2014. Resources : 346 Mt @ 0.45% Cu Treatment Capacity : 7 ktpd of oxide minerals added to the current capacity. Estimated investment : MMUS$ 86

Current status : Projects with feasibility studies in progress and DIA approved in July of 2014. Beginning construction at the end of August of 2014, it is projected that the implementation will be in the middle of 2016.

ENCUENTRO, (Antofagasta Minerals S.A.)

The Encuentro deposit is located about 10 km to the SE of Esperanza and the immediate strategy is to develop the oxide layer in the beginning, which would be the pre-stripping for the sulphured stage, to be developed in the second stage. The development of these usage lines is linked to the Minera Cetinela operations.

i. Encuentro Óxidos:

The Encuentro Óxidos deposit is expected to produce around 50,000 tons of copper cathodes per year, using the existing capacity of El Tesoro. This initiative will permit the current Sx-Ew plant to keep producing to its full capacity, (100,00 tons per year), beginning in 2016, for around 8 years, helping to compensate the diminishing of the productive production of the decline in ore grades of the current deposit from where the mineral is being extracted. This project contemplates new crushing and heap leaching installations, with a tube which will direct the leaching solution or PLS (Pregnant Leach Solution) to the EL Tesoro plant about 15 km away, for processing. The mineral with the highest ore grades will be crushed and sent to the new heap leaching installations, while the minerals with the lesser grades will be processed in a ROM leaching heap. The feasibility Assessment should be finished during the first semester of 2014, to later begin with the pre- stripping in the end of 2014, for a period of two years, followed by primary production in 2016. Currently the Group is analyzing ways to reduce the investment costs, including considering the importation of equipment of China, and the use of a project team lead by Antofagasta Minerals instead of the EPCM contractor.

ACTUALIZACIÓN QUEBRADA BLANCA

The mining site of Quebrada Blanca in an operation which takes advantage of and benefits from a copper deposit located in the Tarapacá region, on the western edge of the Chilean highlands, at approximately 4,300 meters above sea level. The mineral is extracted from an open pit and processed in piles and leaching pits and conventional solvent extraction plants and through electro-winning. The product is cathodes of copper of high purity which are transported in trucks to the Iquique ports and to other national destinations.

The copper mineral extracted from the mine is divided into two types, high ore grade and low ore grade minerals. The high grade mineral is subjected to successive crushing stages to reduce the size and then is transported to a belt system to the agglomeration stage to be later deposited into leaching piles.

Currently, the site presents tasks, activities or parts which show some degree of deviation from the information presented to the environmental regulatory controllers, which has been defined as an Update Modification. This modifications refer principally to: the expansion of the put and of the sterile pit in the south, the enlargement and modification of the site of the leaching dumps and of gravel, the incorporation of a hipogene collection, the update of the original camp and of the treatment of waste water, the updating of the hydrological recharging and the incorporation of a water management area. These modifications have not changed the totality of the mining process described previously and have been maintained within the upper basin of Quebrada Blanca, a historical zone associated with this mining development, without affecting during normal operations the new zones in neighboring basins.

PRODUCTORA (Soc. Minera El Águila Ltda.)

The Productora project is located in the Sierra Coyiguales area, 18 km to the southeast of the city of Vallenar, in the Atacama Region. An assessment of the development reach in Productora indicates that it possesses enough resources to be able to develop an open pit mine and process the mineral obtained through a concentrating plant of 30 ktpd treated, with the purpose of producing copper concentrate with around 50 ktpa of fine content copper and 42 Koz of gold content for a useful lifespan of 20 years. A great opportunity for the project was identified during 2013, which corresponds to an area of copper oxides, which has the potential of significantly reducing the capital costs of prestripping and diminishing the ramp up time, adding another source of income for the project. It is to be noted that an estimate of the oxide mineral resources was not considered previously in the operational plans of the Company for the project.

4.1. Codelco Project - www.codelco.cl

MOLYBDENUM TREATMENT PLANT (Molyb Ltda.)

Within the past few years Codelco has shown that it needs to have an independent molybdenum concentrate processing plant available, so as to not depend critically on the “know how” and interests of a third party. Also, important current and potential clients of Codelco have suggested the convenience of a facility with minimum third party interference. This is to make of Codelco a more trustworthy and safe offering for a critical input used in the business of specialized steels. The project, located in the community of Mejillones has the feasibility Assessment finished and the investment approved by the Board of Directors of Codelco for US$ 394 million, and consists o f a molybdenum plant with an initial treatment capacity which would reach 15 ktpa of fine from toasting and 16 ktpa of fine from leaching. Also it could produce around 4,000 tpa of molybdenum content as iron-molybdenum (FeMo), with the possibility of duplicating the production to 8,000 tpa depending on the commercial demand for this product; 5.4 tpa of rhenium; 4,000 tpa of Mo in bricks and an acid plant which would produce around 32,000 tpa of sulphuric acid. This initiative will be operated through Molyb, an affiliate of Codelco, and will initiate production during the second trimester of 2015. The estimated useful lifespan is of 25 years. The first EIA of the project was favorably received in 2008, with the emission of the Environmental Qualification Resolution # 0230/08. However, due to the current project incorporating rhenium and iron-molybdenum plants, modifications to the EIA had to be made, obtaining the approval RCA in mind 2012, with resolution # 202/2012. The corporation contemplates an expansion project in 2018, with the purpose of duplicating the producing the molybdenum production capacity, of toasting as well as leaching, to be able to reach the production of 30 ktpa and 21 ktpa of fine Mo, respectively.

METAL RECOVERY PLANT / Planta Recuperadora de Metales SpA

Then Planta Recuperadora de Metales project, located in the community of Mejillones, Antofagasta region, and next to the Molybdenum Treatment Plant by Molyb, is a joint property venture between the Korean company LS- Nikko Copper (66%) and state-owned Codelco (34%). It consists in the installation and operation of a processing plant of two by-products coming from the refineries: refinery precipitate rich an copper and copper and anode slime, to recover and commercialize the precious metals contained in these products, such as tellurium, silver, gold, palladium, platinum, and selenium, as well as copper. It is worth noting that the precipitate corresponds to an intermediate product which is generated in the copper refineries, and which after a leaching process in which the copper is removed, is transformed into what is called anode slime. The precipitate possesses a high copper content (averaging over 25%) and important contents (of economic interest) of precious metals as those already mentioned. For their part, the anode slime possesses gold content of over 0.18% and/or silver content of over 17%. The production of the metals will depend on the ore grades of the by-products being processed, estimating that on average the following amounts will be produced each year: 5 tons of gold, 500 tons of silver, 150 kilograms of palladium, 10 grams of platinum, 200 tons of selenium, 20 tons of tellurium, and 1,600 tons of copper sulphide. The type of product and the quantities shows the high value of the by-products to be produced in the plant. Also, an average of 15,000 m3 per year of a copper rich solution will be produced which will be dispatched to Codelco´s processing plants, and eventually to third parties, for the production of copper cathodes from the Sx- Ew processes.

CERRO MARICUNGA (Minera Atacama Pacific Gold Chile Ltda.)

The Cerro Maricunga project, is a property of the Canadian Atacama Pacific Gold company, and is located 140 kilometers to the northeast of Copiapó, in the Atacama Region, in the extreme north of the Cinturón de Maricunga and 20 kilometers to the south of the gold and silver mine of Kinross Gold, La Coipa. This deposit contains resources measured and indicated of 248 Mt with grades of 0.42 gpt of gold, equaling more than 3,334 million ounces of gold content. Also it possesses potential resources in the inferred category which reach 226 Mt with an ore grade of 0.36 gpt, equaling 2.65 million ounces of gold content. According to the Preliminary Economic Assessment (PEA, for the initials in English) finished in March of 2013, the project contemplates extracting through pits of the oxide mineral to be processed at a rate of 80 ktpd though conventional leaching in piles, with which it will produce around 298 Koz of gold on average during the first 5 years of operation, for later maintain an average production of 220 Koz per year of gold Fuente: PEA Cerro Maricunga -Atacama Pacific Gold during the useful lifespan of the project which will last 10 years. In June 2013, Atacama Pacific Gold signed a joint venture agreement with Eton Chile, an affiliate of Exeter Resources who is developing the Caspiche project, for the exploration of potential sources of subterranean water in the shared properties of Cuenca Dos and Laguna Verde, in the Atacama Region. Also, in July of 2013, the company signed an agreement for the purchase of 2.5 million cubic meters of water per year, which represents a flow rate of 80 l/s with the company Aguas Chañar S.A, to supply the demand of water for the alternative of the processing plant of 65ktpd. However, the agreement indicates that it is possible to increase the water usage rate to meet the demands of 80 ktpd of processing, equivalent to 100 l/s. According the company declarations, in July of 2014 the feasibility Assessment was advanced in the modifications of the processing type and of the mining plan to be considered. Likewise, the company indicated that it was waiting for estimates from providers with respect to the purchase of equipment and some elements for the infrastructure. The closing of the negotiations, as the end of the feasibility, was expected for the third trimester of 2014.

2. Barrick Gold Projects- www.barrick.com

PASCUA (Cía. Minera Nevada S.A.) - www.pascualama.com

Pascua is a gold-bearing deposit located 53 km to the north of the ex-mine El Indio, at 4,600 metros above sea level, which forms a unit with the Lama deposit on the Argentine side and which is being developed with the corresponding binational treaty. The reserves are estimated in 17.1 Moz of gold and 560 Moz of silver, principally as oxides. 75% of the mineral will be extracted from Chilean territory

(Pascua) and the rest from Fuente: Barrick Chile Argentina (Lama). The mineral will be crushed at the extraction site and will be transferred to the plants located in Argentine territory. A cyanide leaching plant is being contemplated which would treat the non-impervious mineral (83% of the total), from which

Chilean Mining Investments – Project Portfolio 2015 -2024 89 the metal dore19 is obtained, and a concentration plant for the impervious mineral (17%), from which a copper concentrate rich in gold and silver is obtained. The total projected production would reach 850 koz/ year, in gold and 35,000 koz/year of silver (26 tpa of gold and 1,100 tpa of silver approximately), of which 75% would be considered Chilean production. The marginal content of copper in the concentrate is not availbale. The company suspended20 construction work on the Chilean side of the Pascua Lama project while it worked on environmental requirements and other types of regulations to satisfy Chilean authorities. Meanwile the activities considered for the environmental protection will be continued as they have been authorized. The construction activities in Argentina, wherein the greatest part of the key infrastructure of Pascua Lama is located, which includes the processing plant and tailings tank, were paralyzed also, even though they have been finished. According to the company, the reduction finishing (ramp down) is programmed for the middle of 2014. The company expects to have approximately US$ 300 million21 in costs during 2014 to carry out the ramp down and to comply with the environmental and social obligations. The remaining tasks for project implementation will be done in stages, with specific budgets and work programs, with the purpose of ease in project planning, as well as to control the costs of the same. Barrick will explore opportunities to improve the project´s economy and effective materialization, including strategic associations or payment of royalties and other agreements for the income flow. The company maintains an active option of restarting the development of this mining activity, which has a useful lifespan of 25 years. It is to be noted that in July of 2014, Barrick signed a memorandum of understanding with 15 of the 18 Diaguita communities in the Huasco valley, which considers a six month horizon for these to see, through their representatives and first hand, the main impact of the gold and copper projects, as well as the control measures and mitigation. This memorandum of understanding is aligned with the standards of the Convenio 169 of the OIT, to which Chile is subscribed. Resources : 176.95 Mt @ 1.303 gpt Au; 22.389 gpt Ag; 0.060% Cu Treatment Capacity : 33 ktpd of mineral during the first 3 years and 44 ktpd for the rest of the useful lifespan of the project.

19 Dore metal is a gold and silver alloy, of variable proportions which are molded into bar form. It is obtained from the recovery process of the noble ores present in the minerals and is one of the typical forms of commercializing mined gold. Later the alloy is submitted to a refining process wherein the gold and silver content are separated, for their respective markets.

20 This occurred after the Appeals Court of Copiapó accepted a no-innovation order (ONI) for the project, and in July of 2013 ratified the momentary suspension of the project, after a protection resource was presented by five indigenous communities from the Huasco Valley, referring to a series of environmental irregularities such as the destruction of the Toro 1, Toro 2, and Esperanza glaciers, located in the vicinity of the mine site, and the contamination of the hydrological resources, as a result pf the deposit of waste rock, without being operative the acid draining plant which would impede such. New information is expected at the end of May. It is to be noted that the project has already been fined two times for more than $160 million in March and April.

21 It is hoped to capitalize approximately 25%, related to the water management systems and finish some minor work in Argentina and Chile. The current expenses will depend on a number of factors including the environmental requirements and regulations.

CASPICHE ÓXIDOS (Minera Eton Chile)

The Caspiche project is located in the Maricunga belt, 120 km from Copiapó, between the gold and copper deposit of Cerro Casale, and the Refugio mine, at an elevation of 4,200 to 4,700 meters above sea level. The principal parameters of mining resources that the project has is estimated at 889 million tons, with 0.58 gpt of gold, 0.24% of copper, and 1.13 gpt of silver, which translates into 19.3 million ounces of gold, 41.5 million tons of silver, and 2.1 million tons of copper, which equals 30.1 million ounces of gold equivalent. According the prefeasibility Assessment published in January of 2012, an open pit operation was estimated for 19 years, with a concentration plant treating 150 ktpd, as well as a leaching plant for the oxide minerals and low grade copper. This last could treat minerals at 72ktpd during the first 5 years, to them work at only 33 ktpd during years 6 to 10, after which the oxide operation would be shut down. The average production estimated in the prefeasibility Assessment is estimated around 696 koz/y of gold, and 844 koz/y of silver (21 tpa of gold and 26 tpa of silver approx..) and 110 ktpa of fine copper in concentrate, which would contain one part of both gold and silver. However, in May 2014 Exeter published a report about the results of the Preliminary Economic Assessment (PEA), of the Caspiche project, wherein large modification of the prefeasibility Assessment from 2012 was released. In this Assessment there are three options for materialization: i. Open pit operation, 10 years of useful lifespan, to remove oxide resources and recover gold through heap leaching, at a rate of 30 ktpd;

Chilean Mining Investments – Project Portfolio 2015 -2024 91

ii. Open pit operation with an 18 year useful lifespan, to use oxide resources (years 1 to 5) at 60 ktpd to recover gold through heap leaching and sulphide resources (years 6 to 18) in a concentration plant of 27ktpd to produce copper and, later, to recover gold through cyanide leaching. iii. Mixed operation, open pit with a useful lifespan of 5 years to recover oxidized gold ore through heap leaching at 60 ktpd and subterranean operations (sublevel open stop) to extract sulphur mineral and process it in a concentrator plant of 27 ktpd to produce copper, and later, recover gold through cyanide leaching.} As declared by the company, it would opt for a “staged” development, wherein it would chose the first alternative, valued in US$ 344 million, to recover the oxidized gold ore through heap leaching at a rate of 30 ktpd for 10 years to produce 148,000 oz of Au equivalent during the first 5 years and then 122,000 oz of AU equivalent the rest of the useful lifespan. However this option does not show, with improved market conditions, what could be the most costly alternative (number three) with a value of US$ 1,968 million. Resources : 1,601.7 Mt @ 0.488 gpt Au; 0.177% Cu; 1.167 gpt Ag Treatment Capacity : 30 ktpd of oxidized ore (with the possibility of increasing to 60 ktpd and generate a sulphurs line of 27 ktpd). Estimated investment : MMUS$ 344 (could increase to MMUS$ 1,968 if the third alternative is developed to complement the project). Seawater usage : Not considered. Labor : Information not available.

NUEVA ESPERANZA (Laguna Resources Chile Ltda.)

Nueva Esperanza, previously called the “Arqueros”, Project is located in the Cinturón de Maricunga, to the east of Copiapó. The project consists of three well defined mineral deposits as well as a series of exploratory objectives which are being carried out. The principal deposits are Arqueros, Chimberos and Teterita. Arqueros has been previously mined on a limited scale through subterranean mining from the years 2000 to 2004, wherein the extraction was around 288,000 oz of gold equivalent. Also, Chimberos was developed as a strip mine, giving around 20 Fuente: Kingsgate Consolidate million ounces of silver in the years 1998-1999. These three deposits currently have combined mineral resources of 29.7 Mt with average ore grades of 0.25 gpt of gold and 79 gpt of silver, equivalent to 1.9 million ounces of gold equivalent. The project initially considered developing the remaining resources of the previous development, considering the installation of a processing plant for these minerals with a capacity of 6 ktpd, to produce 250 kg/y of gold and 100 tpa of silver during the 15 years of useful lifespan estimated for the project. At the beginning of 2013 the company established a definitive work agreement meeting the Convenio 169 of the OIT with the indigenous communities affected by the project, with the purpose of diminishing any possible impact. In July, the SEA delivered the approved RCA for the project, with which the company hoped to begin construction in September of 2013. Due to a lack of electrical supply, in the most advanced stages of engineering the project should have considered the generation of electricity, incorporating technology which required lesser consumption, changes which would be implemented within the borders of the property which is in sub-conjunction with the area already evaluated for the EIA: However, and in accordance with the current environmental codes, the changes introduced were submitted for approval to the regional authorities in the area of the Environmental Evaluation System in a new Environmental Impact Declaration (DIA) called “Modificaciones Arqueros”, entered in April of 2014. However, in May 2014 the SEA of Atacama placed an early termination to the environmental evaluation of the Environmental Impact Declaration of the Modificaciones Arqueros project, generating a new delay for the beginning of construction, foreseen for the summer period of 2014/2015. Therefore, the company, in July of 2014 resubmitted the EIA of the project, correcting the lack of information requested by authorities and meeting the requirements which where suggested during the period in which it was in the SEIA. Notwithstanding, in May of

Chilean Mining Investments – Project Portfolio 2015 -2024 93

3025, the company retracted the DIA from the environmental impact evaluation system, due to the development of new mineral reserves in the Chimberos area. The modifications considered in the project contemplate adding the Chimberos and Teterita pits, with a common dump, as well as mineral processing through cyanide leaching in a permanent heap and the addition of a thermoelectric plant. The modifications to the project also require adjustments be made in relations to the crushing plant and complementary tasks, which includes the installation of a mineral transportation belt from the plant to the cyanide leaching area. Also, as is mentioned in the Environmental Impact Declaration, and in accordance with the current identification of the mining reserves and the definition of the treatment capacity, the project will have a useful lifespan of eight years. The additional material which will be extracted and which will feed the plant during the useful lifespan will be around eight million tons, therefore the amount of additional tailings sent to the dumps will be around 27 million tons. The treatment capacity, including the processing of minerals from the Arqueros pit has already been approved environmentally, and increases by 3 million tons per year, equivalent to 78.5 ktpd, with which an average of 500kg/ y of gold and 170 tpa of silver.

LA COIPA FASE 7 (Compañía Minera Mantos de Oro)

La Coipa is a gold mining site located 1,000 kilometers north of Santiago, and 140 km to the northeast of Copiapo, in the gold district of Maricunga, Atacama region. The project denominated as the “Explotación de Minerales Coipa Fase 7” in the environmental impact Assessment has the objective of extracting gold and silver minerals from the new “Pompeya” deposit to allow the operational continuity of the current operation, due to the imminent depletion of the mineral resources in the current pits on the site. The new deposit would be developed through the conventional open pit method and the mineral transported to the current processing plant because of proximity. It is to be noted that the La Coipa site was designed to process up to 15 ktpd of ore, for which, in accordance with what is indicated by the company in the EIA of the project, it is confirmed that increasing the capacity of the plant, the equipment or the installations will be not be necessary. Also it is estimated that the average amount which would reach the processing plant from the site would be less than what has been arriving in the past two years, which will require lower amounts of inputs from the plant. On another note, no construction or expansion of any installation or area related with the camp, workshops, explosives storage, provisions supply area, and industrial or domestic waste management would be required, as all of the existing infrastructure from the La Coipa site will continue to be available for the same purposes. The Environmental Impact Assessment (EIA) presented in July of 2013 was recalled by the company, which coincides with the decision of Kinross to momentarily “freeze” their projects until the markets have stabilized. Therefore the company will concentrate their efforts in the second semester of 2014 on continuing the exploratory studies for the reopening of La Coipa. These will focus on the Pompeya deposit and on the Purén mine, as a joint venture with Codelco 65% Kinross y 35% Codelco). In July of 2015 the company represented the project to the SEA for the environmental approval.

The Dominga project, owned by the Chilean company Andes Iron, is located north of the historical EL Tofo Mine, 70 km north of La Serena and west of the Ruta 5 Norte, in the middle of the Coast Mountain Range in the community of La Higuera, Elqui province, in the north of the Coquimbo region. It consists of an open pit mine which will produce high grade iron concentrates, and as a by-product copper concentrate. The mine projects production of 12 million tons of concentrate per year for pellet feed and 150,000 tons of copper concentrate yearly during a useful lifespan of 22 years. The iron mineral will be sent through a subterranean concentration duct which will be built in the Totoralillo North sector, where it existed in the XIX century as the first mining port of the area. However the copper concentrates would be transported by truck. The operation integrates three areas:

 Sector Dominga: considers the associated installations in two zones of mineral development through strip mining called Rajo Norte and Rajo Sur; a processing plant, a gravel deposit, and a heavy tailings deposit, as well as all of the auxiliary work and installations associated with these procedures.

 Sector Lineal: considers a system of subterranean aqueducts which will transport the water from the Totoralillo sector to the Dominga sector. It also contemplates a subterranean concentrator duct which would send iron ore from the Dominga area to Totoralillo; an electricity transmission line of 66kV and a service road.

 Sector Totoralillo: corresponds to the Shipping Terminal for iron concentrate which will reunite, also, the thickening, filtering, and storage system installations, as well as the areas for collection, desalinization, and water impulsion to the Dominga Sector, and the discharge of the seawater brine. The Environmental Impact Assessment (EIA) was presented in2013, however the company began a dialogue with the la Higuera community in 2011, with the purpose of creating awareness of the project with anticipation with the communities possibly affected by the project. Resources : 2,082 Mt @ 23.3% FeT; 0.07% Cu Treatment Capacity : 95 ktpd of ores

ROMERAL FASE V

Minas El Romeral is one of the CAP Minería mining-metallurgic complexes and considers among the principal assets the iron deposit “Minas El Romeral” and other productive and infrastructure installations necessary for the benefit and management of the mineral it commercializes. The “Romeral Fase V” project, to be carried out in the Coquimbo region, consists in prolonging the extraction activities carried out in the El Romeral Mines, extending the useful lifespan for a period of 13 years. The project will develop high and low ore grade resources in addition to those contemplated in Fase IV, where the current prospections show the existence of 390 million tons of mineral as a mining resource below the current phase. To be able to access these resources it is necessary to expand, the Cerro Principal pit as well as the Norte and Sur dumps, as well as improve some of the current installations. This expansion contemplates improving and using part of the existing infrastructure, therefore only a few additions on a smaller scale will be required, such as the expansion of the mechanic shops, a new parking area for mining equipment, changing houses, lunchrooms, the relocation of powder kegs and the explosives plant. Additionally, it will carry out technological adaptations and maintenance in the existing infrastructure to reach the desired extension of the useful lifespan. It is to be noted that the project does not contemplate an increase in the extraction rates of the deposit nor of the processing capacity of the existing plant. Resources : No information available. Treatment Capacity : No information available.

1. Ingenieros Asesores Ltda. Projects

ARBIODO

The Arbiodo project corresponds to a non-metal mining project whose main objective is the production of iodine and nitrates from caliche, passing through a series of processes within the area of development and the industrial plants of the Mining area. From the territorial and analytical points of view, the project is made up of three fundamental areas, which correspond to the Coastal Area, the Pampa Area, and the Mine Area. The Costal Area is made up of the water intake for seawater at the extraction point, as well as part of the length of the duct which is 18,83 km long, in this area there are two pumping stations associated with the water flow; the Pampa Area is made up of 28.34 km of aqueduct; and the Mine Area, which corresponds to the place where the mineral extraction takes place and wherein all of the productive and industrial processes for obtaining iodine and nitrates takes place, and furthermore, where the industrial plants and installations associated with project development will be located. This area contains 14.43km of aqueduct for seawater. The section of the aqueduct for seawater will have a service road, which will be used for the installation of the pipeline as well as for maintenance. Along with the pipeline will be the electrical transmission line which will feed the pumping stations for the water source, and will also will also deliver the energy for the functioning of the Mine Area installations. Also, it contemplates the exportation of the finished product to the port of Chañaral, preferably, which is located in the town with the same name in the Atacama Region (however the use of the Antofagasta and/or Mejillones Ports area also being considered, both being in the Antofagasta Region. Resources : No information available.

Treatment Capacity : 400,000 t/year of nitrate prills, 20,000 tons/year of boric acid and 2,7800 tons/year of iodine.
