INVESTMENT IN THE CHILEAN MINING INDUSTRY 2013-­‐2021 Portfolio

Executive Summary

Investment in the Chilean mining industry stands at US$112.5 billion. Mining companies have announced 49 projects involving upwards of US$90 million each. Most are in progress or undergoing review, with investment decisions slated for no later than 2017 and start-­‐up by 2021.

The portfolio is led by copper mining, with 28 projects and two additional investment lines.1 These include Codelco’s six structural projects, expansion of megadeposits such as Escondida, Pelambres and Collahuasi, concentrate operations replacing depleted SX-­‐EW operations (El Abra, Quebrada Blanca, , etc.) and new undertakings by medium-­‐size miners . Second in line is gold mining, with ten projects accounting for 19.4 percent of investment. Three major gold projects (Caspiche, Cerro Casale, El Morro) will also produce copper while two other replacement projects will help revitalize major gold mining operations. Iron, titanium and nitrate are also attracting fresh investment. Most investment targets are in northern . While leads the way with US$43 billion or 38 percent, new large-­‐scale gold mining operations in Atacama are attracting a healthy US$34 billion or 30 percent. Fully 46 percent of all investment comes from Chilean companies , including majors such as Codelco and Antofagasta Minerals and medium-­‐size Copec and Pucobre. Accounting for the balance are eleven countries, notably Canada (27%) in gold mining and Japan with a wholly-­‐owned operation (Caserones) and a minority stake in several companies. India and China are venturing into iron mining. Due to the nature of the mining business, all investment forecasts are subject to change. In the industry, projects in progress are considered highly certain while those under review are noted for varying degrees of uncertainty. As development moves forward, projects undergo changes that tend to impact expected production capacity, investment amounts, and time frames.

This update to Cochilco’s 2012 mining investment report shows a US$8.2 billion increase in . value This is the result of a US$7.36 billion upward revision of 22 projects plus a net US$900 million gain caused by the entry of nine new projects and the start -­‐up or cancellation of seven other projects in 2012. In addition, ome s project schedules underwent changes ranging from a one-­‐year acceleration to a two-­‐year delay . Overall, shorter-­‐term investment s declined and more were shifted to beyond 2015. Additions to production capacity were also impacted as a . result Refined copper production capacity in 2021 should stand at 8.1 million tons, rising to 8.4 million once all projects start to operate at capacity. Most of the increase will come from concentrate production, which should rise from 3.7 million tons in 2012 to 6.8 million in 2021. By contrast, SX-­‐EW cathode production should decline from 2.3 million tons in 2012 to 1.4 million in 2021. One effect of increased concentrating capacity will be a sharper rise in ore volume fed to concentrating plants. Due to persistent declines in copper grades, throughput is expected to rise upwards of 180 percent, from 450 million TPY in 2012 to 1.2 billion TPY in 2021, with concentrate production capacity rising 86 percent from 3.7 to 6.8 million TPY in the same . period As a result, plants are being redesigned on a larger scale, resulting in added costs and requiring more energy, water and other inputs to produce a imilar s amount of copper, with the attendant impact on demand for these goods and services. Increased productivity is one of the new challenges facing the Chilean mining industry as it seeks to remain competitive.

I. Introduction

The Chilean Ministry of Mines considers investment a strategic pillar of long-­‐term mining growth. This is an industry that turns resources in the ground into tangible wealth that contributes decisively to the economic and social growth of all Chileans. The Chilean Copper Commission (Cochilco) systematically tracks mining investment and reviews planned projects and resulting opportunities. Findings are published annually for the benefit of interested public officials and private industry players . This report provides an update to mining industry investment in Chile, notably projected investment and production capacity potential through the next decade. It has three sections:  Inventory of copper, gold, silver, iron, and industrial mineral projects. The tally includes all projects worth upwards of US$90 million either in progress or likely to materialize no later than 2017.2 It does not include initiatives in the exploration or stage below the above amount.  Planned investment by Codelco and large and medium-­‐size copper, gold, silver, iron and industrial mineral mining companies.  A ten-­‐year projection and review of the mined (concentrate; SX-­‐EW cathode) copper production potential through 2022. Includes a global estimate of gold, silver, molybdenum, iron and industrial mineral production. Project amounts, time frames and other nformation i is gleaned from public company reports. While there is no guarantee that projects will materialize as stated, these reports stand as reliable proof of interest and company perceptions of the geological potential and economic and political conditions prevailing in Chile.

2 The methodology is explained in Annex A. Copper mining project details are provided in Annex B. Annex C describes gold and silver projects and Annex D review iron and industrial mineral ( iodine, nitrate, potassium salts, titanium oxide) projects.

Copper mining accounts for fully 77 percent of the projected US$112.5 billion investment amount, followed by gold and silver mining with 19.4 percent. The remaining 3.6 percent is destined for iron and industrial minerals mining projects . Of this amount, 12.8 percent has been materialized, 63.3 percent will be disbursed in 2013-­‐2017, and 23.8 percent will materialize in 2018-­‐2021. The methodology used to compile and project process data is shown on Annex A.

3.2 Investment Distribution by Project Status and Type

Projects often run into internal and external issues that force a revision of the original plan. Per the methodological criteria explained in Annex A (2), projects herein are classed as either greenfield (i.e., new) or brownfield (i.e., replacement or expansion of existing operations). In terms of status, they are in progress or in the feasibility or prefeasibility stages. These factors help more accurately assess the likelihood of materialization as stated. Conditions assessed are base line, probable, and possible.5

5 Baseline: In progress and highly probable. Probable: Replacement, expansion or new projects in the feasibility stage by companies operating in Chile and slated to start up through 2017. Possible: New projects Feasibility study underway by new entrants and projects in the pre feasibility stage.

Although 44.2 percent of the portfolio is expected to materialize in 2013-­‐2017, projects classed as Possible are subject to greater uncertainty. This segment includes new entrants who have yet to complete a feasibility study and others who have not secured a permit to start construction prior to 2017. Possible gold mining projects account for ¾ of planned investment and 15 percent of the portfolio. Projects in the prefeasibility stage are mainly copper projects not scheduled to come on stream before the end of the and decade therefore subject change to .

4.3 Estimate Review

By helping offset depletion, s investment reviewed here have a strong impact on overall copper production in Chile. Extent and use of maximum production capacities have a long-­‐term impact on mining and related activities , especially the supply of goods and services, an endeavor of strong local relevance . While actual production expected in the next few years will not necessarily use the full installed capacity, maximum production profiles are a valuable tool for estimating demand for related , goods services and human resources across regions and nationwide. The charts below shows the expected behavior of both concentrate and hydrometallurgical operations and projects.

4.3.1 National Forecast Chilean mined copper production should rise to a maximum of 2 8. million tons refined copper in the next decade, a 36.8 percent increase over the nearly 5.5 million tons estimated for 2012.7 The annual rate of growth for the period 3 would be .2 percent. By 2022, depletion and end of mine life will cut output from existing operations, not considering new investment amounts some of them will require, to 3.64 million tons refined copper, 2.35 million tons less than the baseline year 2012 ( ). Therein lies the importance of materializing projected investment plans, as these would add 4.55 million TPY or 56 percent of maximum production capacity estimated for 2022. Planned developments rely mainly on increasing concentrate capacity from 3.7 million tons in 2012 to 6.9 million tons in 2022, for an annual rate of growth 6.4 percent. With that, concentrate output as a share of mined copper production w ould expand from 62 percent in 2012 to 84 percent in 2022. Hydrometallurgical copper is expected to slide from over 2 million tons SX-­‐EW cathodes in recent years to some 1.9 million tons through 2018 and 1.32 million by 2022. Causes include a declining number of hydrometallurgical projects, depletion of leachable ores and closure of major operations, notably Codelco’s Salvador, Mina , Sur and Radomiro Tomic Oxides, as well as Quebrada Blanca and other private operations. That said, Codelco and other players may yet move to prolong the lifespan of some operations while others may shift to mining underlying primary sulfides.

4.3.2 Maximum Production Capacity By Likelihood While the above capacity is estimated based on all projects materializing as stated, mining projects are inherently subject to change. As such, maximum production capacity profiles are classed per the criteria in Annex A(2) in a manner similar to the corresponding investment profiles. Table 10 shows that maximum production remains subject to internal and external contingencies. The baseline profile, consisting of existing operations and projects in progress, should stand at 4.6 million tons refined copper by 2021. This is equivalent to only 77 percent of maximum production capacity in 2012 and to 57 percent of estimates for 2021, which explains the critical nature of the less advanced projects reviewed below. The probable profile, which includes projects in the feasibility study stage by companies with existing operations in Chile and slated for start-­‐up no later than 2017, should add an additional 1.8 million tons, 390,000 tons above the current maximum production . capacity The largest quantitative increase should come from possible projects, which includes those in the preliminary feasibility study stage and new entrant projects with feasibility study underway. These would add a combined 1.7 million tons or 21 percent of total maximum capacity expected in 2021.

7 Production stood at 3.40 million tons concentrate and 2.03 million tons SX-­‐EW cathodes, for a total of 5.43 million tons.

4.3.3 Regional Forecast While Chile’s overall copper production capacity is expected to expand 34.8 percent from 2012 to 2021, growth will not be equally distributed mining across districts . In Atacama, refined copper production capacity should jump 194 percent from 409,000 tons in 2012 to 1.2 million tons in 2021 due mostly to the copper output of three major gold projects and four other medium-­‐ and large-­‐scale copper mines. These projects should significantly boost mining and related activities in the region . Production in Tarapacá should expand 96 percent to some 1 million tons by 2021, driven mostly by the Collahuasi Phase III Expansion and the new Quebrada Blanca undertaking. However, most projects in Atacama and Tarapacá remain classed as Possible and thus subject to change. As an established mining district, Antofagasta is expected to retain the lead. While maximum capacity should rise 19.6 percent to about 3.95 million tons refined copper, projects are either in progress or have feasibility studies well underway. As some major operations, including RT Oxides, Chuquicamata Open Pit and Mina Sur, are being wound down, most projects new are designed recoup to capacity . The Andina expansion in Valparaíso is expected to increase output by 32.5 percent in the period. The single-­‐largest project in O’Higgins is the new El Teniente mine level, also designed to recover production capacity.

4.4 Maximum Concentrate Processing Capacity

As the roster shows, most projects are designed to increase copper concentrate production. With grades declining across the , board new plants are being designed to handle larger a throughput. As plant requirements are driven by throughput rather than output, larger, more expensive processing facilities, increased ore and overburden extraction and additional milling and flotation work translate into higher consumption of fuel s, power , water and other key inputs . Shown below is annual concentrating plant throughput from existing and new operations coming on stream.

Increases in gold production come from primary production or from production secondary to copper mining. By 2021, these projects are expected to increase maximum production capacity to 178 tons, up 256 percent over the 49.9 tons reported in 2012. At present, primary gold production contributes some 30,000 kg/yr. while production secondary to copper mining contributes an additional 19,870 kg/yr. Future contributions from both sources are estimated at 145,600 and 39,800 kg, respectively, both from existing operations and new projects coming on stream. Silver projects in this report should contribute some 1,526 TPY to maximum production capacity. Sources when fully operational 2021 in are gold mining (1,226 TPY) and copper mining (300 TPY).

17 Chilean Copper Commission -­‐ Research Department July 2013

5.2 Molybdenum

Most molybdenum produced in Chile is a byproduct of copper mining. Major copper concentrate projects in the portfolio (Caserones, Sierra Gorda, Esperanza Upgrade, Quebrada Blanca Phase II, Relincho)8 contemplate producing 36.7 kTPY molybdenum concentrate. These contributions should place the refined molybdenum production capacity at about 74 kTPY by 2021.

The Chuquicamata Underground and RT Sulfides Phase II projects should help keep the contribution to maximum production capacity of Codelco’s Chuquicamata and Radomiro Tomic Divisions stable at about 25 kTPY molybdenum concentrate.

5.3 Iron

Production in 2012 stood at 17.33 million tons iron ore or some 10.2 million tons refined iron. The project portfolio and associated output is expected to increase maximum production capacity by 111 percent to 37 million tons in 2021. At implementation, rojects p by iron concentrate, screening and pellet feed producers CAP, Minera San Fierro and Santa Fe Mining, plus secondary production from the Santo Domingo copper project (Capstone), were expected to contribute some 20.1 million tons iron ores or 11.9 million tons refined iron,9 as noted in Table 16.

8 Collahuasi, Los Pelambres and Valle Central expansions not considered due to insufficient information. 9 Iron products contain from 58% to 65% Fe.

The net result will boost Chilean production capacity to 31 million tons iron ores or better than 19 million tons refined iron content in the second half of this . decade

5.4 Industrial Minerals

Nitrate investment projects undertaken by SQM are expected to progressively increase annual production capacity by 2.5 million tons nitrate, 11,000 tons iodine and 1.55 million tons potassium chloride. In addition, White Mountain Titanium’s Cerro Blanco project will produce some 200 kTPY titanium dioxide concentrate ( 95% TiO2) with production of some 1.5 million TPY feldspar10 starting in 2016.

10 Chilean feldspar production is a modest 8 kTPY.

VI. Concluding Remarks

The overall investment portfolio includes 49 initiatives worth an overall US$112.6 billion. Leading the field is the copper industry mining , with 30 initiatives worth US$86.7 billion. Highlights include:

 The Codelco investment plan focuses on six structural projects (Ministro Hales Mine, Radomiro Tomic Sulfides Phase II, El Teniente New Mine , Level Andina Phase II, Andina Pit-­‐Plant Transfer) designed to ensure long-­‐term sustainability. Codelco has two additional investment lines covering a range of projects smaller .  Large private miners (Escondida, Los Pelambres, Collahuasi) hold reserves that stand among Chile’s and the world’s largest. They are currently expanding operations in order to raise productivity and prolong mine lifespan.  A distinctive element are copper concentrating projects taking over from fast-­‐depleting leachable surface ore operations (RT Sulfides, QB Hypogenic, El Abra Mill, Lomas Bayas Sulfides). The result will a increase net in copper production capacity.  New entrants reflect sustained interest in joining one of world’s the leading mining districts.

Second in line with ten projects and 19.4 percent of overall investment is gold mining. Highlights include:

 Three large-­‐scale projects (Caspiche, Cerro Casale, El Morro) will also produce copper, while two replacement projects will be instilling new life into major gold mining operations.  The binational Pascua-­‐Lama project is being required to ensure its activities are compatible with the law, after which construction could resume.  Atacama is the second-­‐largest investment destination, most of it going to gold mining.

The portfolio also includes five iron, four nitrate and one titanium dioxide mining project, all at widely varying stages of development. As is often the case in the industry, projects in progress are considered highly certain while those under review are noted for varying degrees of uncertainty. As development moves forward, projects undergo changes that tend to impact expected production capacity, investment amounts, and frames. time Such ariability v is reflected in this update to the mining project portfolio. This report shows a US$8.2 billion increase in value. This is the result of a US$7.36 billion upward revision of 22 projects plus a net US$900 million gain caused by the entry of nine new projects -­‐ and the start up or cancellation of seven other projects in 2012. In addition, some project schedules underwent changes -­‐ ranging from a one year acceleration to a two-­‐year delay. Overall, -­‐ shorter term investments declined and more were shifted to beyond 2015. Additions to production capacity were also impacted as a result. Refined copper production capacity in 2021 should stand at 8.1 million tons, rising to 8.4 million once all projects start to operate at capacity.

20 Chilean Copper Commission -­‐ Research Department July 2013

Most of the increase will come from concentrate production, which should rise from 3.7 million tons in 2012 to 6.8 million in 2021. By contrast, SX-­‐EW cathode production should decline from 2.3 million tons in 2012 to 1.4 million in 2021. One effect of increased concentrating capacity will be a sharper rise in ore volume fed to concentrating plants. Due to persistent declines in copper grades, throughput is expected to rise upwards of 180 percent, from 450 million TPY in 2012 to 1.2 billion TPY in 2021, with concentrate production capacity rising 86 percent from 3.7 to 6.8 million TPY in the same period. As a result, plants are being redesigned on a larger scale, resulting in added costs and requiring more energy, water and other inputs to produce a similar amount of copper, with the attendant impact on demand for these goods and services. Increased productivity is one of the new challenges facing Chilean mining industry it as seeks to remain competitive.

Annex A -­‐ Methodology

1. Scope This report covers investment in replacement, expansion or new copper, gold mining, iron and industrial minerals projects by Codelco and medium-­‐ and large-­‐scale private miners. It considers projects worth upwards of US$100 million either in progress or likely in to materialize 2013-­‐2017. The “Prior to 2013” category refers to project outlays (i.e., studies, construction) made through 2012, followed by estimated outlays through 2013-­‐2017. Projects scheduled for start-­‐up beyond 2017 are identified as . such Project particulars are complemented by estimations on copper output added, if any, plus notes on current status. Information is provided on -­‐ a best guess basis, based on data current at the time of writing. Where no such data is available, annual investment allocations are estimates not necessarily supported in . sources 2. Project Type , S tage of Development and Likelihood Investment information is qualified by project type and stage of development. Projects are ranked from most to least likely. 2.1 Project Type This classification provides information on project likelihood, which varies for existing and new operations. Categories are as : follows a) Replacement: Includes brownfield projects designed to prolong the life of the mine and maintain existing production by addressing declining grades and/or depletion . issues b) Expansion: Includes brownfield projects designed to increase operating capacity, scale up production and cut unit costs, notably as ore grades start to decline. c) New: Includes greenfield projects requiring environmental and other clearances, construction of facilities and opening up a new site. Also includes brownfield projects involving a complete change from one mode of production to another (i.e., leaching to concentrating), which often requires developing n a entirely new deposit . 2.2 Stage of Development Based on the assumption that projects in a more advanced stage of development are often more likely to materialize, these are classed follows as : a) In Progress: Investment approved and permits secured. Detail engineering and construction underway. b) Feasibility Study Stage: Undergoing feasibility and environmental (EIA or DIA) review, investment decision not yet . made c) Prefeasibility Stage: Undergoing initial review; decision to proceed to next stage not yet made.

2.3 Likelihood Projects are ranked as Baseline, Probable or Possible based on type and stage of development.

22 Chilean Copper Commission -­‐ Research Department July 2013

a) Baseline: In progress. Deemed highly probable, although start-­‐up may undergo delays. Production is added that to of existing operations. b) Deemed Probable: Includes easibility f -­‐stage replacement, expansion or new projects by companies with operations in Chile, with start-­‐up scheduled for 2013-­‐2017. While subject to significant changes or delays, they are deemed certain as they prolong the lifespan of existing operations. c) Deemed Possible: Includes easibility f -­‐stage projects by new entrants, replacement or expansion projects with start-­‐up scheduled no earlier than 2018, and all prefeasibility-­‐stage projects. Projects by new entrants often face hurdles that can cause significant changes and delays, or even cancellation. In the case of brownfield projects, a far-­‐off start-­‐up date often results in major revisions that can also significant cause changes and delays. 3. Codelco Investment Plans and Sources of Information Investment estimates11 are based on information presented in Codelco’s 2013 Business and Development Plan (PND 2013) for development and/or research projects . Development projects are directly connected to production prospects and approval requires compliance with certain return on investment standards. These include: a) Structural Projects: Selected development projects that fully leverage available mineral resources and provide a baseline for long-­‐term growth. This report provides specifics and investment amounts. b) Other Development Projects: Included in he t Codelco investment portfolio are discrete or shorter-­‐ term projects deemed complementary to structural projects and thus essential to company continuity. This report provides specifics and investment amounts. Codelco also implements research projects designed to acquire new information considered relevant to further development. While not listed as part of a specific investment project, these include prefeasibility, feasibility, and environmental assessment of prospective sites, basic and generative exploration, and R&D. Given their manifold nature, these projects are reported on the aggregate. While outlays on equipment replacement, facility , upgrades environmental cleanup, workplace safety, and employee benefits in the PND 2013 also require API approval, they are omitted in order to facilitate comparison with private firms which do not provide such information. Also omitted are investments not requiring API approval and thus outside the purview of this report. All information is gleaned public from reports provided by company officials or on the Codelco web site, complemented by data contained in the Codelco Business and Development Plan and other official reports submitted on a regular basis Investment to the Cochilco Evaluation & Enforcement and Compliance Department (DEIF). As such, the information herein should be construed as a strategic planning tool rather than as binding on the reviewing agencies. 4. Private Mining Investment and Sources of Information Sources include public reports and announcements culled from company web sites, the news media, trade publications, filings and to the environmental assessment system.

11 Spending by Codelco requires Investment Project Authorization (API), a review conducted jointly by Cochilco and the Ministry of Social Development. Disbursements considered as investments by Codelco (i.e., deferred expenses and the like) which require no authorization are not included. Inclusion in the 2013 PND does not imply authorization.

Often only global amounts and intended -­‐ start up year are known. In such cases, annual estimates are based on tentative completion time frames reported to the environmental assessment system or on empirical knowledge of like projects. The review includes all projects under construction. Projects under review were checked for progress and their investment, start-­‐up schedule and estimated production profiles were updated based on the most recent information available. Changes noted included : a) New principals following changes in ownership. b) Production capacity and products of interest. c) Investment amount, start -­‐up date and project schedules. d) Inclusion of new projects. e) Removal of recent -­‐ start ups. f) New requirements, such as the use of seawater . While projects are assumed to reflect outlays made during the construction stage, prior outlays may be included. Where no precise information is available, -­‐ start up year is estimated as shown below. 5. Estimating Start-­‐up Dates Internal and external factors may impact project development. Some of the latter include the need to cut electricity cost s, modify environmental impact statements and/or secure construction permits . The former, for their part, often encompass project timing relative to corporate goals, securing financing, and the need to enhance investment and/or operating cost indicators. Where no public start-­‐up date announcement exists , Cochilco uses the following methodology: a) A standard one-­‐year delay is deemed if a project is impacted by external , factors even if these entail only minor changes to the feasibility study. b) A standard two-­‐year delay is deemed if a project requires reformulating a prefeasibility or feasibility study. 6. Projected Mined Copper Production Capacity Maximum potential concentrate and/or SX-­‐EW production capacity is the sum of maximum production profiles by existing mining operations and projects starting up within the , decade shown as tons of refined copper. Future profiles for existing operation are based on recent production performance and estimation of key parameters, including ore grades, concentrating plant capacity, and acid consumption by hydrometallurgical operations. Assumptions are based on maximum plant capacity operating nonstop 360 days a year, based on data reviewed by Cochilco . Project production profiles are based on company descriptions of maximum processing capacities under nonstop operation 360 days and a year key expected mining and metallurgical parameters . Tracking project rankings , production profiles are also classified from most to least . likely All figures are shown estimated as maximum potential capacity relative to 2012, based on the most recent data available as of this writing.

Annex B -­‐ Copper Mining

I) STRUCTURAL CODELCO PROJECTS (www.codelco.cl) MINISTRO HALES MINE (Ministro Hales Division)

Ministro Hales stands in Antofagasta, halfway between the Chuquicamata minesite and the city of Calama. It is a copper sulfide deposit holding reserves estimated at 289 million tons with 0.96 average copper grades and high silver content. The homonymous Codelco Division was set up to develop and operate this mine.

Once in operation, the mine is expected to process up to 50 kTPD in a concentrating plant sited adjacent to the open pit. Processes handled include primary crushing, transport by conveyor belt, stockpiling, milling (one SAG mill and two ball mill s), and flotation.

High arsenic levels will require fluidized bed roasting (up to 350 kTPY) -­‐ yielding high grade concentrates (37% refined copper content) to produce some 183 kTPY refined copper and 300 TPY silver. Plant gases will be abated in a sulfuric acid plant. Due to their special characteristics, these concentrates may also be used as smelter feed or sold.

Massive pre-­‐stripping has created an opportunity to leverage a significant volume of leachable ores. As such, a complementary project now underway will convey ores to a heap leaching site, with the resulting solution fed to the Chuquicamata Division Hidrosur SX-­‐EW Plant for an expected 79,000 tons refined copper in 2014-­‐2016.

This is a deep deposit and plans include moving to underground mining in future the .

Workforce: 3,000 during construction; 450 during operation. Throughput: 50 kTPD sulfide ores.

Est. Investment Amount: US$3.43 billion.

Status: Under construction. Once concluded, dry (primary crusher, stockpile), wet (milling, flotation, tailings thickening) and roasting systems will be load-­‐tested. Start-­‐up slated for late 2013.

RADOMIRO TOMIC SULFIDES PHASE II (Radomiro Tomic Division) Phase II involves mining sulfides emerging at Radomiro Tomic as overlying oxides d. become deplete Estimated reserves stand at 2.6 billion tons with 0.48 average copper grades.

Plans are to continue mining the current open pit and process ores in a 200-­‐kTPD concentrating plant slated to come on stream in late 2017. This will add an estimated 350 kTPY refined copper and 7 kTPY molybdenum concentrate.

The project will extract and desalinate seawater at a 1,600 l/s reverse osmosis plant, then pump it 160 km to an altitude of 3,000 m. A conventional tailings dam will be through used 2021, then replaced by thickened tailings technology that will allow for optimized dam use and sizing, help reclaim more water, and reduce particulate emissions. This will require subsequent construction of a high-­‐ density thickening plant.

The Division also plans to leverage the available hydrometallurgical infrastructure to bioleach low-­‐grade sulfides.

Workforce: 12,100 during construction; 2, 200 during operation. Throughput: 200 kTPD sulfide ores.

Est. Investment Amount: US$5.43 billion, including desalination and pumping infrastructure but not the thickening plant.

ANTUCOYA (Minera Antucoya Ltda.)

Located 125 km NE agasta of Antof and 45 km from the coast, with proven and probable reserves of 642 million tons and 0.35 copper grades (0.21 cutoff grade). Expected to produce 85 kTPY copper cathodes through the first then decade, settle 80 at kTPY through the second and last decade of expected life .

Antucoya will be a conventional -­‐ open pit mine. Ores will be leached in a dynamic heap and processed in an SX-­‐EW plant using raw seawater. Albeit a low-­‐grade greenfield project, the orebody is relatively shallow and pre-­‐stripping to remove some 35 million tons of overburden should take only nine months. The overburden/ore ratio is a low 1:1 and the deposit lies within established a mining zone, which ensures ease of access to existing infrastructure, including energy, water , and human resources.

Construction was halted n i late December 2 201 to revise the project given rising current and potential costs. Following adjustments, construction restarted in Q2 2013.

Workforce: 5,000 to 7,000 during construction , 1,400 during operation . Throughput: High-­‐grade ores to 96 kTPD; run-­‐of-­‐mine to 38 kTPD. Est. Investment Amount: US$1.9 billion, not including a potential acid plant. Status: In progress after restart. Start -­‐up expected in mid-­‐2015.

ESPERANZA UPGRADE (Minera Esperanza S.A.)

Minera Esperanza, 30 km from Sierra Gorda, in Antofagasta, is optimizing its operations through two Environmental Impact Statements (DIA) filed in 2013.

Esperanza Upgrade III, the first of these, had its DIA approved in May 2012. It seeks to increase the supply of critical inputs (water, process inhibitors and reagents, etc.), process oxide ore resources in areas to be cleared for use as dumpsite s, and construction of a new molybdenum processing plant.

The leading component is a molybdenum plant to be built near the collective flotation area, next to the existing concentrating . plant This includes a standard 5.5-­‐kTPD selective flotation circuit encompassing primary flotation, cleaning flotation, filtration, drying, and concentrate storage. The resulting copper-­‐gold concentrate will be the “tailings” to be sent to the existing concentrating plant for processing.

The Esperanza Upgrade IV – Process Optimization, whose DIA was filed in June, focuses on improving existing milling and flotation systems through a secondary and tertiary crushing plant designed to complement current capacity. Plans also contemplate new concentrate and tailing thickeners.

Once completed, the Esperanza upgrades will boost concentrating plant throughput by 12 kTPD to 105 kTPD, which would translate into an additional 19 kTPY copper concentrate. The molybdenum plant will produce an estimated 11.5 kTPY during operation lifespan.

Workforce: 875 during construction; 49 during operation. Throughput: An additional 12 kTPD sulfide ores and 5.5 kTPD molybdenum. Est. Investment Amount: US$550 million (Esperanza Upgrade III: US$200 million; Esperanza Upgrade IV – Process Optimization: US$350 million).

2.1 SQM S.A. (www.sqm.cl)

PAMPA HERMOSA (SQM) The project stands south of Pozo Almonte, in the new Nueva Victoria Industrial Zone, site of SQM’s long-­‐ term iodine and nitrate production facilities. The project, designed to increase prilled iodine production from 4.5 kTPY to 11 kTPY, also calls for a new 1.2-­‐million TPY sodium/potassium nitrate . plant Some 37 million TPY of nitrates will be mined in five areas. After leaching, solutions will be transported to iodine plants and then to solar ponds for crystallization of salts and subsequent purification in the nitrate plant. Workforce: 882 to 1,438 during construction (12 months); 448 to 678 during operation . Throughput: Not available. Est. Investment Amount: US$1.03 billion. Status: In progress , RCA approved. Construction considers gradual implementation over five . years

COYA SUR POTASSIUM NITRATE PLANT (NPT4) (SQM Industrial) The plant will stand in the Coya Sur Industrial Zone, 2 km south of María Elena, 77 km SW of Tocopilla and 198 km NE of Antofagasta. The plant will include ore stockpiles, waste salt disposal sites and evaporation ponds. Salts will be processed, including by lump ore dissolution, thickening, crystallization and centrifugation, to obtain a final product in prilled or bulk form. The plant will produce 550 kTPY sodium/potassium nitrate or 450 kTPY of both, plus 40 kTPY boric acid over 40 years. Production is shipped the to Port of Tocopilla for transportation. Workforce: 380 to 570 during construction; 30 during operation. Throughput: Not available. Est. Investment Amount: US$250 million. Status: Early work in progress, awaiting DIA approval . Start -­‐up expected in 2014.

PAMPA BLANCA EXPANSION (SQM Industrial) Pampa Blanca, south of SQM’s María Elena hub, will add six new mining zones increasing the nitrate extraction rate 37.3 to million TPY over 50 years. Plans call for construction of two industrial areas to increase iodide production to 10 kTPY iodine equivalent in order to feed a new 10 kTPY iodine plant to produce 3.425 million TPY nitrate-­‐rich salts (1.293 million TPY sodium nitrate). The project will have a new power transmission system and be supplied by 500 l/s of seawater pumped from the Bay Mejillones of . Workforce: 765 during construction; 510 during operation.

2.2 White Mountain Titanium Corp (www.wmtcorp.com)

CERRO BLANCO

Cerro Blanco, named for the mountain on which it lies, is a rutile deposit near the port city of Huasco, 39 km west of Vallenar, Atacama. Recent company estimates point to reserves of 81.5 million tons with 1.97 average grades and 0.8 cutoff grades. The overburden/ore ratio is an estimated 78. 1. The project calls for conventional open-­‐pit development and processing of some 11 million TPY of ores to produce 4 million TPY of rutile over 20 years and 4 months. A ravity g concentration, flotation and magnetic concentration plant will produce some 73 kTPY rutile concentrate with 96 percent grades. Complementary feldspar production considered in the original feasibility study will be reevaluates at a later time by the company. In April 2012 the company secured seawater extraction permits for a desalination plant. The project has an estimated lifespan of 24 years, including six months for acquisitions and detail engineering, 18 months for construction, 21 years for operation , and one year for site closure. Workforce: 450 to 705 during construction ; 658 to 795 during operation. Throughput: 11.4 kTPD rutile. Est. Investment Amount: US$380 million. Status: Feasibility study underway, start -­‐up expected in 2016.
