ITEM 1: SUMMARY

This Technical Report was prepared to support the October 24, 2012 news release of Cerro Resources NL (Cerro), and details the resource estimation process and results by Cerro for its Namiquipa Silver Deposit (The Property), in the state of Chihuahua, Mexico.

The Namiquipa deposit is located adjacent to the village of El Terrero in Chihuahua, Mexico, 145 km west- northwest of the City of Chihuahua.

The deposit occurs as a low-sulphidation epithermal system transecting a suite of shallow dipping breccias and ignimbrites of andesitic and rhyolitic composition. Extensive silicification has occurred around a major north trending shear zone that is host to the epithermal veins.

Following acquisition of the property in 2010 a concerted exploration effort by Cerro during 2011-12 has enabled this maiden resource estimation.

A total of 86 diamond holes were drilled in 2011-12 for 32,151 meters to principally test the Princesa vein system at the historic La Venturosa Silver Mine. A small number of these holes were also drilled as initial evaluation of the sub-parallel America vein system as well as the Mexico and Esmeralda veins.

Drilling has been completed on nominal 50 meter sections transverse to the vein system with holes designed to test the target mineralization at 100 meter centers. Except for high grade veins that were stratigraphically sampled the drill-holes were generally sampled on one meter intervals. Drill samples were submitted to the ALS Group for sample preparation in Chihuahua and assayed by method code ME-ICP61 (a 33 element four acid ICP-AES procedure) in Vancouver. On-going analysis of QAQC data using ORE proprietary standards indicates no systematic variations that are outside of expected laboratory error of ± 10%.

The mineralization occurs as the superposition of three related mineralizing events that were rich in zinc, lead and silver. Interpretations of the broad mineralization boundaries, as defined by drill-hole intercepts, were interpreted in vertical cross-section and plan view to define the extent and geometry of the mineral system. Internal zonation of this mineral system into high grade and low grade zones for each of silver, lead and zinc was achieved using indicator kriging. Sample statistics indicate lognormal unimodal populations for silver, lead and zinc. Variograms are poorly defined due to the wide drill spacing but do indicate a cross-strike range of around 20-30 meters. Block grades for silver, lead and zinc were interpolated using Ordinary Kriging based on 2 meter composited assay data located within geologically defined, oriented and scaled search ellipsoids. Separate ellipsoids were used to match the structural orientations of the principle veins. The same search and interpolation parameters were used for all models.

Page 1

Namiquipa Silver Deposit Technical Report

The resource was calculated as the tonnage weighted sum of grades within the interpreted mineralized zones whose silver equivalent grade was in excess of the appropriate cutoff. Tonnages were estimated from a density database of 5,728 samples.

At a cutoff grade of 100 g/t AgEq the Namiquipa resource is 4.6 million tonnes grading 103 g/t silver, 0.9% lead and 1.7% zinc for an average silver equivalent grade of 154g/t (Table 1). Silver Equivalent grades were calculated using the 12 month average metal prices of US$31.50/oz Silver; US$0.89/lb Zinc; and US$0.92/lb Lead. Metal recoveries were not considered in the calculation.

As the drill density is sufficient to define the continuity and shape of the mineralization but insufficient to map meso scale grade variations within the mineralized zones the resource is classified as Inferred.

The Silver equivalent grades (“AgEq”) have been calculated using the 12 month average metal prices of US$31.50/oz Silver; US$0.89/lb Zinc; and US$0.92/lb Lead. Metal recoveries are not considered in this calculation. 4. Mineral resources which are not mineral reserves do not have demonstrated economic viability. The estimate of mineral resources may be materially affected by environmental, permitting, legal, title, taxation, socio-political, marketing, or other relevant issues.

Fieldwork can be carried out all year round.

One of the historic mine camp buildings located on the Property was converted to a site office and a large well equipped core shed was constructed with core cutting, core storage and logging areas. Three phase electrical lines were upgraded to supply stable power to the core shed and office during the latest round of exploration drilling. Satellite internet service is installed at the office.

Physiography of the area in the vicinity of El Terrero and the Property is dominated by a north trending valley with very gently rolling topography. El Terrero is at an elevation of 2,000 m. A north trending range of hills 5 km west of El Terrero reaches an altitude of 2,700 m.

ITEM 6: HISTORY

The district was discovered in 1811 by the Spaniard Marciano Mascareñas with the first mining claims staked in 1916. In 1929 the Japanese Mining Company Santo Domingo Mining Co. established a cyanidation plant with a capacity of 75 tons per day. This was modified to a flotation circuit with 75 tons per hour capacity in the 1930's. In 1936 the Company closed due to labour problems, low silver prices and a significant increase in water pumping costs.

During 1946-47 H.C. Dudley and W.N. Fink of Minera Venturosa S.A. undertook a vigorous exploration program, including diamond drilling, which resulted in the discovery of new mineralisation both in old workings and below the mined areas. In 1948 this company established a modern plant with a 450 tons-per-day capacity which operated until 1955 when, due to labour problems and water shortage, mining again ceased. Total production is recorded at 737Kt for 330t silver, 25Kt lead and 37Kt zinc (Table 3).

Namiquipa Silver Deposit Technical Report

In October 1990, Compania Minera de Namiquipa completed construction of a 50 ton-per-day oxide flotation plant. This was upgraded to 120 tons per day in 1992. During the period 1990 to 2000 production was mainly from oxide ore producing silver with low grades of lead. 341,557 tons was milled for 98,791 kg of silver and 4,892 tons of lead. Average grades were 281 g/t Ag and 1.4% Pb.

From 2000 to 2002 sulphides from the 100 meter to 150 meter level of the ‘America’ area were mined. This coincided with the construction in 2001 of a sulphide flotation plant with 250 ton per day capacity. This plant produced concentrate with average grades of 1,400 g/t Ag, 18% Pb & 42% Zn that was shipped to Pasminco’s smelter in Avonmouth, England. Mill throughput in 2001 and 2002 was 80,100 tons for 17,986 kg of silver, 2,433 tons of lead and 6,591 tons of Zinc. The silver grade was 225 g/t, plus 3% Pb and 8.2% Zn. In May 2002 the plant was shut down due to falling prices of zinc and silver plus increased water in the underground workings.

ITEM 7: GEOLOGICAL SETTING AND MINERALIZATION

7.1 Regional Geology

7.1.1 Stratigraphy

Northwest Mexico consists of translated and accreted terranes along the south-western margin of the North American craton, which have been intruded and covered by coeval and younger igneous rocks since the middle Mesozoic. Mesozoic and early Tertiary compressional tectonism was followed by several styles of extensional tectonism beginning in the middle Tertiary. These events generated distinctive lithologic sequences across the region, which are divided into the Western, Central and Eastern domains. Cross- cutting the central and eastern domains, is the northwest trending (‘SMO’); a Late Cretaceous to Early Tertiary Laramide mountain building Orogeny.

The geology of the SMO is divided into the Lower Volcanic Complex (‘LVC’) and the Upper Volcanic Supergroup (‘UVS’). The LVC is characterised by a series of andesitic volcanic and sedimentary rocks interlayered with felsic pyroclastic units deposited during the Eocene – Oligocene. Calc-alkaline granodioritic to granitic batholiths and stocks have intruded volcano-sedimentary rocks of the LVC. The LVC is unconformably overlain by the UVS, a large volume of caldera-related, pyroclastic rhyolite that was deposited during an episode of rift-type magmatism in the Middle to Late Oligocene (Masterman et al, 2006).

Page 9

Namiquipa Silver Deposit Technical Report

7.1.2 Structure

Namiquipa lies at the southern continuation of the Basin and Range extensional setting. A component of dextral movement on regional-scale basement NW trending faults has helped to develop extension on the NS structures at Namiquipa.

7.1.3 Mineralization

The Mexican epithermal deposits are Tertiary in age, generally ranging from Middle Eocene to Early Miocene, and their spatial distribution matches the distribution of the volcanism associated with the evolution of the Sierra Madre Occidental and the Sierra Madre del Sur. In northern Mexico the deposits are divisible into two distinct parallel but overlapping metallogenic belts containing Ag-Au and Ag-Pb-Zn ores (Figure 1). The Ag- Au ores are concentrated in the western belt commonly occurring in andesitic rocks that comprise the LVC. The Ag-Pb-Zn ores are concentrated in the eastern belt and are associated with the pyroclastic rocks of the UVS. Also situated in the east is a Pb-Zn-Ag-(Cu) metallogenic belt that is thought to have formed at higher temperatures (>300°C) usually close to intrusive centres and predominantly hosted by carbonate units.

The Namiquipa deposit is located in the eastern Ag-Pb-Zn belt and is hosted by volcanic rocks of the UVS.

7.2 Local Geology

7.2.1 Stratigraphy

The host rocks in the vicinity of the Namiquipa deposit are comprised of an interlayered sequence of Tertiary age felsic lapilli tuffs, welded tuffs, and andesite porphyry, all of which are silicified. The felsic rocks display strong illite (pyrite) alteration (Figures 3, 4).

Intruding the volcaniclastic package are numerous small (20-50meter wide) high level diorite stocks exhibiting marginal breccias.

The volcanic stratigraphy at Namiquipa, as defined by Corbett (2011, 2012) and Cummings (2012) is believed to contain three units with possibly intervening time gaps between formations. They are:

 a lower tuff unit at depth in the south which thickens across a growth fault.  the Namiquipa dome-breccia complex comprising overprinting andesite porphyry domes with contact breccias and cut by hydrothermal breccia pipes, all with intense silica-Kfeldspar alteration, extending in the earlier permeable tuffs.

Page 10

Namiquipa Silver Deposit Technical Report

 an upper ignimbrite unit which caps the domes to the north and becomes less altered in the uppermost portion.

The Namiquipa dome-breccia complex is interpreted to locally overlie the earlier ‘lower tuff unit’ as an endogenous dome-breccia complex, which many have vented to the surface (Corbett, 2012). This principle rock type at Namiquipa is termed the coarse andesite porphyry and is rimmed by extensive andesite porphyry breccia characterised by mainly Kfeldspar altered clasts within a chlorite matrix, although Kfeldspar flooding of these breccias with chlorite altered clasts results from continued brecciation. Increased silica-Kfeldspar alteration occurs at conformable brecciated dome contacts with the underlying earlier sequence. The host permeable tuffs have undergone pervasive silica-Kfeldspar alteration in association with dome emplacement. Several different types of andesite porphyry are recognised in drill core which include a common medium grained andesite porphyry and other fine grained and flow banded styles. While it is difficult to distinguish some tuffs from hydrothermal breccias, features such as the milled breccia character, disseminated matrix and vein sulphide, the common dome clasts, along with matrix flooded Kfeldspar alteration and faulted contacts, all suggest multiple hydrothermal breccias which have erupted from deeper level porphyry intrusions.

7.2.2 Structure

Extensional settings such as Namiquipa are characterised by listric faults which generally host the best precious metal mineralisation within flat plunging ore shoots localised in steeper dipping fault portions (Corbett, 2011). The cuspate form of veins in plan view with an east dip on the main America and Princesa veins and steep west and vertical dips on the Esmeralda and Antenna veins respectively, is consistent with a listric fault extensional vein origin with associated hanging wall splay veins. The listric faults are broken into segments by NW transfer structures, presumably parallel to regional fracture systems. These structures influence changes in dip of the listric faults or otherwise limit mineralisation. Furthermore, intersections of the listric and transfer faults appear to localise steep plunging ore shoots in the America vein at the General and Americas shafts. While horizontal ore shoots of supergene Ag has been exploited in the Princesa vein at about 100m deep and locally extending to deeper levels, the additional deeper mining at the America vein might be indicative of higher Ag grades at depth.

7.2.3 Alteration

Hydrothermal alteration is classed as silica-Kfeldspar (adularia) style, typical of higher temperatures proximal to the andesite porphyry dome source rocks. Much of the Kfeldspar may occur as the low temperature form, adularia, and grades laterally to lower temperature chlorite-dominated alteration assemblages, as prograde potassic grading to marginal propylitic alteration. This alteration is best developed in the andesite domes and

Page 11

Namiquipa Silver Deposit Technical Report contact breccias, and forms laterally extensive alteration within the permeable wall rocks and also extends along faults, commonly as a precursor to mineralisation. Illite-pyrite wall rock alteration which is more typical of epithermal Au deposits is only well recognised as an overprint in faults, or in the uppermost sequence of younger ignimbrites and within the dome sequence at the southern extension of the Namiquipa structural corridor. Green-blue clays close to locally mineralised faults may comprise celadonite which is common in poly-metallic Ag epithermal deposits.

Magnetic imagery delineates a 3 km long NS structural corridor at Namiquipa limited to the east and west by the bounding faults (Figure 5). While deep oxidation commonly in the order of 200m may account for much of the magnetite destruction in the Namiquipa corridor, this is interpreted to overprint earlier magnetite destructive illite-pyrite hydrothermal alteration. Oxidation of the pyrite within this alteration would have provided acid ground waters to promote magnetite destruction.

7.2.4 Mineralization

Mineralisation transgresses the uppermost elements of the stratigraphy and so post-dates the entire volcanic succession.

Mineralisation is hosted by steeply dipping quartz veins. The favourable andesite hosting mineralisation is overlain by a more recent andesite and rhyolite and regionally dips about 20° to the southwest. At the south end of the mined zone, the dip increases to about 60° sharply and there the bed is covered by a soft, clay like andesite tuff or ash often of a marked red colour.

Mining has clearly focused upon a set of north to north westerly trending and steep east dipping veins. Vein location can be seen from collapse and open stopes at the surface. Dump material comprised quartz varying from mostly saccharoidal to comb quartz with locally colloform banded chalcedony/opal and including late stage amethyst; plus sulphides and carbonate. Early pink K-feldspar-pyrite alteration is associated with stockwork quartz veins. Sulphides are generally coarse grained and comprise pyrite, brown sphalerite and galena and are overgrown by calcite. These mineral assemblages are interpreted to be consistent with the level of Ag ore deposition in a Fresnillo style polymetallic Ag vein system which are silver rich and probably gold poor. A valuable description of the mineralisation is contained in Shafelbine, 1955. It is quoted as follows:

“The six principal veins all strike about north 20o east at the north end of the property but at the south end the veins fan out so that the eastern most veins have a strike of north 20o west. Dips near the surface are fairly constant and vary from 70º to the east for the western most vein to vertical, and 70º to west for some of the veins further to the east. Nearly everywhere the vein

Page 12

Namiquipa Silver Deposit Technical Report dip steepens with depth until they, at 250 meters below the surface, are nearly vertical. The veins are essentially quartz replacement of breccia filled fissures in the andesite. The principal vein shows evidence of several ages of mineralisation, each with its distinct type of mineral. Chief vein constituents in the sulphide or unaltered zone are quartz, sphalerite, galena, pyrite, fluorite, chalcopyrite with silver minerals and minor gold. Chalcedony is also present in many areas. The mineralisation sequence was probably as follows; evidence supports the theory that the veins were opened several times.

 Quartz with finely crystalline galena, pyrite and chalcopyrite containing quantities of silver minerals.  Quartz, fluorite, and sphalerite, with some galena & pyrite  Chiefly fluorite with massive galena & some sphalerite, plus small quantities of gold and silver  Quartz with chalcedony, marcasite, galena & manganese minerals, all probably derived from surface leaching & redeposited in vein vugs at depth.

The veins are oxidised to about 100m below the surface. In the oxidised zone the lead and zinc minerals have been leached and the vugs resulting remain open or contain limonite as a residual constituent of the marmatitic sphalerite. The lead minerals are in the form of cerussite and rarely anglesite or wulfenite. Increased quantities of barite are formed near the surface, where the silver minerals are native silver and cerargyrite. The veins show distinct zones of silver and lead enrichment at or near the base of oxidation. A second broad zone of enrichment was found about 50 meters below the surface. In general, the transition between oxides and sulphides is made in a distance of a few meters; however, the base of oxidation is very irregular with many tongues of oxide extending tens of feet into the sulphide zone. As would be expected the richer more open vein areas in general, show greater depth of oxidation. Outcrop of the veins are obscure and no gossans as such are evident. As mentioned above, a large halo of discoloured rock surrounds the veins. Several normal faults cut the veins at nearly right angles but their displacement is not great. All the faults show that the south limb has been dropped. Dykes are few in number and are small. At the south, the ore in the vein is believed to be localised by the extensive andesite tuff bed which is almost impervious to solutions and is not competent, mechanically, to support vein openings. The evidence, therefore, supports the theory that the tuff flow acted as a solution trap. Veins have nowhere been traced into the tuff more than a few feet before being lost’.

Namiquipa Silver Deposit Technical Report

Acuna’s unpublished memo of February 1992 mentions that between the 120 and 150 meter levels in the America Vein (also known as the Venturosa Vein), there is an increase in the galena grain size, a higher sphalerite content and pyrite changes from fine to medium grained. This variation in grain size correlates with decreasing silver grades. Generally the level of oxidation at the America Vein was in the vicinity of Level 4 (approximately 100m RL), whereas in the Princesa Vein the level of oxidation (although at Level 4) is at approximately -70m RL.

ITEM 8: DEPOSIT TYPES

The Namiquipa deposit is interpreted to be consistent with the level of silver ore deposition in a Fresnillo style polymetallic vein system which is silver rich and gold poor (Fleming, 2010). Comparisons of many deposits similar to Namiquipa has facilitated the estimation of controls to Au-Ag mineralization in low sulphidation epithermal deposits, and the coincidence of several of these controls contributes towards the development of ore shoots (clavos), which host more ore, typically as wider and higher precious metal grade veins (Corbett, 2007).

Figure 8 Fluid flow path for Namiquipa mineralisation culminating in the upper level level of polymetallic Ag-Au mineralization on the mineralization classification of Corbett (2009).

Page 18

Namiquipa Silver Deposit Technical Report

G. Corbett a world renowned geologist who specializes in epithermal deposits has reviewed the drill core and geologic controls at the Namiquipa deposit and has made recommendations during the course of the project that have assisted the evaluation of the Property. Mineralization at Namiquipa is described as of the low sulphidation epithermal polymetallic Ag-Au style. Although Au is not prominent in the Namiquipa data base, the Zn equivalent is included in some resource inventories. Many polymetallic Ag-Au deposits display zonation patterns which include dominant Cu-Au at depth (typically of the initial quartz-sulphide Au + Cu style grading to higher crustal level Ag + Zn>Pb and highest level Ag-rich mineralization (Figure 8). Veins and vein- breccias commonly comprise early quartz and pyrite followed by sphalerite > galena with lesser chalcopyrite and Ag sulphosalts, and later stage carbonate. Sphalerite color provides a good indication of levels in the hydrothermal system as compositions vary from deeper level high temperature Fe-rich dark sphalerite, through brown, red and yellow, to Fe-poor white sphalerite formed under low temperature conditions at highest crustal levels. Carbonate varies with the acidity of the bicarbonate waters from which it was deposited (Corbett, 2007; Leach and Corbett, 2008), with rhodochrosite most commonly present in better mineralized systems.

Early quartz-pyrite mineralization is evident at Namiquipa commonly as fluidized fine grained silica-pyrite breccias which have penetrated to high crustal levels within the host. Many veins examined to date at Namiquipa contain red-yellow sphalerite indicative of moderate temperatures of formation. These veins contain Ag mineralization within or associated with sphalerite-galena commonly as Ag sulphosalts such as tennantite-tetrahedrite minerals such as the Ag end member, freibergite, and so there is a Zn:Ag correlation. In the northern portion of the prospect (DDH’s NAM47 & 18) the main Princesa vein displays a clear transition from initial red through to yellow sphalerite. Of greatest interest is that immediately main vein in DDH NAM47, elevated Ag (3540 g/t) is associated with the mineral assemblage pyrite-white sphalerite-argentite with local kaolin. This low temperature mineralization formed elsewhere in elevated crustal settings (Corbett, 2007), is classed as the epithermal end member of polymetallic Ag-Au veins (Figure 9), and should be targeted at Namiquipa. This low temperature mineralization overprints yellow sphalerite and barite, both typical of polymetallic Ag veins, and local kaolin. This observation has direct impact on recommendations for future exploration at the Property.

ITEM 9: EXPLORATION

Work by Cerro has included surface mapping, geochemistry, surface geophysics and drilling

9.1 Surface Mapping

Cerro undertook confirmation mapping of the project area to validate, and locate with GPS, work completed by the previous mine operators Mina Rio Tinto SA de CV.

9.2 Soil Geochemistry

A program of soil geochemistry has been initiated to trace the known mineralization to the north and explore for unknown structures. An orientation program in the central north of the drill area was successful in identifying anomalous zones of silver and lead to the east of the Princesa Vein. Samples of sieved -80 mesh

Page 20

Namiquipa Silver Deposit Technical Report soil have been collected on a 100 x 20 metre grid and submitted to ALS for assay using method MEICP-41. The program continues to target zones east and north of the known vein systems.

9.3 Geophysical Surveying

Zonge International Inc. completed Ground Magnetics over the Project Area and a Complex Resistivity Induced Polarization survey across the central portion of the Namiquipa Prospect in May 2011. The CRIP program was extended to the north and south in June 2012.

9.3.1 Magnetics

The objective of the magnetic survey was to identify concentrations of magnetic minerals in the subsurface that could be correlated with metallic mineralization and to delineate structural trends on both a local (in the vicinity of the CRIP survey) and a regional scale. The mapped mineralized veins in the CRIP survey area are located in a broad, smoothly varying area of moderately low magnetic signature. However, there are some very subtle features in the gradients in the vicinity of and in between the mapped veins. Regional structural trends over the entire survey area indicate a dominant set of N-NE trending magnetic lineaments. Other structural trends appear as NW trending and E-NE trending lineaments. Magnetic basement appears low in the central survey area and uplifted to the north and south.

The survey consisted of 119 lines of total magnetic field data collected on east-west lines ranging from 2 to 5.3km in length, with the average line length 3.6 km. Line spacing was 100 meters over most of the survey grid except the central area (in the vicinity of the CRIP survey) where line spacing was 50 meters (Figure 10).

A total of 434 line-km of ground magnetic data were collected. Magnetic data were acquired with an optically- pumped GEM-19 Overhauser magnetometer manufactured by GEM Systems. The Overhauser magnetometer is a proton-precession magnetometer that uses radio frequency signals to achieve high sensitivity and low power consumption, making it useful for minerals mapping applications. The GEM system was integrated with a Trimble GPS accurate to about 1.5 m. A similar magnetometer was used as a base station magnetometer to monitor diurnal changes during the survey. The GEM-19 Overhauser magnetometer uses less power than proton precession magnetometers, has higher sensitivity, and can withstand high magnetic gradients.

The magnetics identifies a central zone of low frequency response which corresponds with the Namiquipa alteration and mineralization (Figure 5) surrounded by zones high tenor high frequency response. The contacts between these zones are sharp suggesting faulted boundaries. Northwest and northeast discontinuities are evident throughout the magnetic patterns.

9.3.2 Complex Resistivity Induced Polarization

Zonge International Inc. completed a Complex Resistivity Induced Polarization survey across the central portion of the Namiquipa Prospect in May 2011. This program was extended to the north and south in June 2012 (Figure 12).

Pole-dipole CRIP data were collected along 7 lines for a total coverage of 10.8 km using a receiver dipole “a- spacing” of 50 m. Line separation was nominally 350 meters. Data were collected for N-spacing of N= 1 to 9 with partial coverage from N = 10 to 15. The survey was performed in the frequency domain at fundamental frequency of 0.125 Hz and utilized the 3rd and 5th harmonics in order to use a 3-pt decoupling technique. The collinear pole-dipole survey electrode array consists of an asymmetrical setup of a fixed infinite remote transmitter (TX) electrode, and on-line roving TX electrode.

The results of the CRIP survey indicate a large IP anomaly in the depth range of 100-300 meters in the central survey area that is correlated with high-angle resistive features in places, and conductive features in other. The chargeability anomaly is located on the Princesa Vein and although the surface projection of the anomaly is centred on NAM-013, 039 and 061 the core of the anomaly in Long Section (Figure 11) is located close to the southern growth fault and is intersected by drill-holes NAM-003 (33 meters containing 2.2% Zn) and NAM-059 (23 meters of 1.3% Zn).

ITEM 10: DRILLING

10.1 Cerro Resources Drilling

A total of 86 diamond drill-holes for 32,507 meters have been drilled into the Namiquipa Deposit in the period March 2011 to June 2012. Drill-holes are located on a nominal 50 line meter spacing over a strike length of 1000 meters (Figure 13). Drilling has tested the down-dip extension of the historic workings from 200 to 500 meters with a nominal toe spacing of 100 meters.

Drilling at the southern end of the field has intersected quartz veining transecting clastic sediments and andesites but with alteration features more compatible with near surface meteoric fluids.

Drilling at the northern end of the field, north of the North Shaft Fault, has intersected a comparable stratigraphic sequence of ignimbrites but with little alteration and mineralization. Stratigraphic correlations suggest a 70 meter displacement, north-block down.

Drilling was completed by Major Drilling Mexico SA de CV using track mounted top drive diamond core rigs. Holes were collared in HQ, reamed to HWT for 6 to 12 meters of casing and then continued in HQ tool till drilling conditions necessitated a reduction to NQ. Generally this occurred when old stopes were intersected.

10.2 Drill-hole Surveying

10.2.1 Hole Collar Surveying

Drill-hole collars are survey using Differential GPS with an Trimble TSC2 series recorder which has centimetre accuracy. Collar coordinates are read in Zone 13 WGS 84 UTM format.

10.2.2 Down-hole Surveying

Drill-hole loci are surveyed using a Reflex single-shot electronic instrument at 50 m intervals down hole. The down-hole survey data, including magnetic field and temperature readings, are recorded by the drillers and manually entered into the drill database. More recently the survey data was extracted directly from the survey tool in CSV format. Results are plotted and visually scanned for consistency. Values may be adjusted arbitrarily to the average of adjacent readings if the magnetic field and/or temperature value(s) indicate erroneous readings.

10.3 Data Capture

Drill data is stored in a series of EXCEL files containing drill-hole name, interval depths, and the parameters particular to that file. Geological logging data is recorded on paper and manually transferred to digital form Excel data files are routinely checked for data errors prior to importing into GEMS (Gemcom). GEMS is a modern comprehensive geological database and modeling software program utilizing Access as the database.

10.4 Logging & Sampling Protocols

10.4.1 Geological Logging

All core preparation is completed on-site at a purpose built facility by geologists assisted by trained technicians under the supervision of a senior geologist. The core is measured, metre marked, photographed (both wet and dry) and logged for basic geotechnical properties of recovery, RQD, fracture density and rock strength. Density determinations are made at five metre intervals down the hole.

Geological logging is then completed by geologists, prior to half core sawing and sampling for assay. The geological logs record all pertinent data related to lithology, alteration, structure and mineralization. Separate from-to intervals are recorded with each category of observation. Under lithology the rock is described and named; under alteration, superimposed mineral assemblages are recorded along with the nature of their occurrence; under structure, meso and macro scale structural features are identified are where possible their orientation measured; under mineralization, economic minerals are identified, their occurrence described, and volume estimated. Paper logs are scanned

10.4.2 Density Measurements

Density measurements are made at 5 m intervals along the core using the specific gravity principle. Half core samples of approximately 10cm length are weighed in air then coated in candle wax to seal voids. The samples are then re-weighed in air and water and the weights recorded automatically into the specific gravity (SG) database along with the drill-hole name and sample depth. The SG is calculated as:

SG = Wpw / { [Wa/(Wa/(Wa-Ww))] – [(Wa-Wpw)/Dw] }

Wpw weight in air pre waxing

Wa weight of the waxed sample in air

Ww weight of the waxed sample in water

Dw density of candle wax = 0.93

Page 27

Namiquipa Silver Deposit Technical Report

Weights are collected using an OHAUS Explorer Pro model EP 6101 scale with a load capacity of 6kg and a resolution of 0.1g. The unit is capable of weighing both on and below the stage. The scale is calibrated before each use using standardized weights supplied by Ohaus. Communication between the unit and a Foxpro database on the computer is controlled by Tec-IT TWedge version 2.4 programmable software.

A total of 5,728 determinations have been collected from the drill core for an average value of 2.43±0.17 t/m3 within a data range from 1.21 to 5.72.

Averaging the data by 50 meter elevation slices (Table 4) shows the gradual effect of reducing oxidation with depth as the average SG values increase from 2.31 to 2.51 t/m3.

Table 4 Analysis of SG data by Depth

Multiple regression of the SG data against assay value (specifically silver, lead and zinc) indicates a strong correlation of SG value with grade. The accuracy of the regression function improves with grade tenor such that for samples with a lead or zinc grade in excess of 0.1% the standard deviation of the estimated value is 48% of the data standard deviation whist for samples with a lead or zinc values in excess of 1% the standard deviation of the estimated value is 60% of the data standard deviation.

The equation and statistical comparison of the regression of SG against silver, lead and zinc grades for samples with lead or zinc grades in excess of 0.5% is presented in Table 5.

10.4.3 Core Cutting

The core is sawn in half using a MK® water cooled manual feed core-saws with a 14” diamond tipped blade. The core is cut to optimize the primary vein orientations where applicable.

10.4.4 Core Sampling

Drill data was generally sampled on one metre intervals except for high grade veins that were stratigraphically sampled with a minimum interval of 0.2 meters (1,058 samples in a total of 23,698). For various reasons, such as poor recovery or make-up lengths to keep sampling intervals on meter marks, 4.5% of the sample lengths were greater than 1 meter.

Although 95.5% of the sampling has been completed on standardised one metre intervals there is still a component of non-uniform volume support introduced by the variation in core size from HQ to NQ. At this stage of the evaluation this error is considered small as 88% of the assay samples were drilled by HQ tool and only 12% by NQ tool. For high grade samples (those with AgEq values in excess of 100 g/t) the ratio is 89%:11%.

10.5 Relationship of Drill Intersection to True Width

The majority of drill-holes have been drilled at angles between 55 and 65° (Figure 14). As the vein systems dip at approximately 75° this gives an intersection angle of approximately 45° which equates to a true width of approximately 70% of the quoted drill intersection. True width calculations have no impact on the resource estimation as the drill-hole data is composited to standard lengths and then treated as point data for interpolation purposes.

ITEM 11: SAMPLE PREPARATION, ANALYSES AND SECURITY

11.1 Assaying Methods

All samples were prepared and assayed by ALS Group (ALS), a wholly owned subsidiary of Campbell Brothers Ltd. Sample preparation occurred at their Sample Preparation facility in Chihuahua and assaying at the Vancouver laboratory. ALS is registered in North America under ISO 9001:2000 and ISO 17025.

At the Chihuahua facility rock samples are placed in metal trays and dried in an oven at 120ºC for 3-4 hours. The dried sample is then run through a Boyd Crusher to produce a product 70%<2mm. The sample is riffle- split to a Pulp Master (~200g) and a Coarse Reject. The Pulp Master is pulverized in a Ring Pulverizer to a product 85%<200# using a 250g bowel. A split of the pulp is dispatched to Vancouver by UPS overnight transport.

Samples are assayed using method code ME-ICP61, a four acid digest with an ICP-AES reading for 33 elements (Figure 15). Assay over-runs are repeated using method ME-OG62, an ore grade analysis using a four acid digestion and a reading using equipment suitable to the element.

11.2 QAQC

Standards and duplicate assays are routinely run by ALS as part of their internal quality control program.

In addition a structured QAQC assay program consisting of blanks, duplicates and standards is a fundamental part of the Cerro assay process. The distribution of blanks, standards and duplicates within the 2011-12 drill program is summarized in Table 6.

11.2.1 Duplicate Samples

From drill-hole NAM-061 onwards duplicate samples were routinely submitted for assay along with the standards. The duplicates are created by the laboratory at the sample preparation stage by cutting a second sample from the primary crush. This is annotated as a “D” sample and reported separately.

Four hundred and sixty nine (469) core samples were duplicated by the laboratory as a check on sample homogeneity. Summary statistics for the data are presented in Table 7. The average Relative Percentage

Error (RPE) for silver was 0.7%, 1.3% for lead and 0.6% for zinc, both with small standard deviations (Table 7). These results are well within acceptable limits for homogeneity. The data is also presented as a scatter plot with an almost perfect 45° regression line (Figure 16).

11.2.2 Standard Reference Samples

A suite of proprietary standards from ORES Pty Ltd (Melbourne, Australia) have been used throughout the drill program. These include ORE131a (low grade silver and sulphide), ORE133a (medium to high grade silver and sulphide), ORE134a (high grade silver and sulphide) and ORE36 (zinc sulphide).

Standards are submitted on a rotating basis at the rate of 1 in 40 (2.5%). Based on drill length there has been a maximum of 15 standards submitted in one drill-hole, with an average of 1 or 2 of each standard (total 4 to 8) being submitted in each hole (Figures 17, 18). Seven holes, from the first phase of drilling, did not have standards included in the submission.

Page 33

Namiquipa Silver Deposit Technical Report

As the 10g Standard sachets can be too small for routine analysis and re-analysis two sachets are generally included in the sample bag. In the case of silver 12 samples have been returned with NSS [insufficient sample], 30 for lead and 43 for zinc. There has been an increasing frequency of this happening in the latter part of the drill program.

ORE131a (Table 8, Figures 19, 20)

Silver values range from 29 to 34ppm with a mean of 31.5 ± 1.01ppm. The average grade is 102% of the expected mean. Lead values range from 1.55 to 2.03% with an average grade of 1.67 ± 0.06%, equivalent to 97% of the expected mean. Similarly, zinc values range from 2.57 to 3.37% with an average grade of 2.78 ± 0.10% which is 98% of the expected mean. RPE2 statistics confirm this close association of the standards with their product specifications.

Two anomalies occur in the Pb & Zn RPE plots corresponding with samples [131680 – NAM005 141.5m] and [151680 – NAM057 245.5m] which are over-estimated by 10 and 20% respectively. Examination of the other standards that were included in these work orders shows no consistent pattern of over-estimation and suggests that these results are random. This is confirmed by the average ratio of standard value to specification being close to 100% for lead and zinc in both work orders. The slight underestimation of silver in work order CH11257676 is not consistent with general trends as ORE134A generally assays lower than ORE131A.

1 Mean ± Standard Deviation 2 The Relative Percentage Error [RPE] is used to measure the variability between samples. An unbiased comparison has an average RPE of zero with a minimal spread about this average. The RPE is calculated as :

AVERAGEVAL UE - val1 RPE = * 100% AVERAGEVAL UE which for two samples reduces to :

val - val RPE = 2 1 * 100% val2+ val 1

The RPE is equivalent to the HARD plot (Half Average Squared Deviation) of other workers. The RPE statistic provides a measure of the precision of the data and the graph over time or sample number indicates whether there are systematic trends in the data.

11.2.3 Blanks

From drill-hole NAM-062 the original, finely pulverized Quartz blanks that had been used for the majority of the program were replaced by locally sourced rhyolite rock chips (Figure 27). The rhyolite provides a more realistic test of the inter sample contamination at the pulverizing stage of sample preparation by scouring the bowl and hence assimilating any contaminant material left from the previous sample. Although the quartz powder was pulverized the fineness of the material would have reduced its ability to scour and hence clean the bowl.

As blanks are generally submitted on every 40th sample (2.5%) the number of blanks per drill-hole obviously reflects the drill-hole depth. There are only 9 cases where blanks were not submitted with a drill-hole. In early sampling there was an attempt to submit blanks on an irregular basis following high grade material but this program lost momentum due to the number of inclusions. In general there are 3 to 4 blanks submitted with each drill-hole. Figures 29, 30 present comparisons of the blank value with the preceeding sample value for silver, lead and zinc in each of the Quartz and Rhyolite materials.

For silver in quartz there is one anomalous blank [150325 – NAM054 123.5m] of 2.4g/tAg following a 0.5ppm value. This sample is weakly anomalous in lead, 71 over 21ppm but not in zinc, 90 over 82ppm.

Blank sample [136025 – NAM018 112.6m] returned values of 2.7ppm Ag, 448ppm Pb and 7ppm Zn following an ore grade sample of value 428ppm Ag, 4.96% Pb and 592ppm Zn. This represents a contamination of approximately 1% (0.63% for silver, 0.90% for lead and 1.18% for zinc.

The presence of lead contamination in Quartz blanks follows a regular monotonic increasing pattern when plotted in logarithmic scale (Figure 29). This represents a contamination of approximately 1% regardless of sample tenor.

A similar monotonic increasing pattern occurs in Zinc when plotted in logarithmic scale; this has a gradient of approximately 1%. The group of anomalous samples on the right of the graph with Blank values of 402ppm zinc regardless of preceeding sample values are tentatively explained as a batch of contaminated blanks.

In the Rhyolite Blanks there have been no examples of silver contamination regardless of preceding sample tenor.

Lead and zinc in the Rhyolite blanks display a similar 1% contamination trend to that seen in the Quartz blanks. The one anomalous value in this grouping is sample [158268 - NAM072 201.25m] where the assay results for the Blank value and the preceeding sample have obviously been swapped around during sampling or at the laboratory as the Blank has been returned with values of 48.3ppmAg, 1.81%Pb, 7.16%Zn following a drill sample of 0.2ppmAg, 106ppmPb and 119ppmZn.

There is some variation in the material as evidenced by:

 the slight increase in tenor of copper in recent time (NAM-046 – 061),

 the presence of anomalous Zn values (all at 402ppm) in drill-holes 1 to 30,

 a U-shaped trend in lead values from early highs to lows to later highs

The tenor of these trends are not considered significant to impact on the usefulness of the Quartz Blanks. A similar analysis for the Rhyolite Blanks indicates no obvious temporal trends.

11.5 Sample Security

Drill core was collected from the drill site at the end of each 12 hour shift by Minera Tasmania staff and stacked at the Core Shed waiting processing. The Core Shed and offices are manned 24 hours per day by operating staff or night watchman. Following logging and sampling drill samples were bagged in lots of 10 with the company name and sample sequence written clearly on the bag. The bags were collected (and receipted) from site by ALS staff and driven directly to the Chihuahua facility.

11.6 Assay Database

Assay data is emailed to the project office by ALS as CSV files. These files are manually merged into a HOLEID/SN file that contains the drill-hole name, sample from-to and the unique sample number allocated to that sample. QAQC samples are also listed in the file in sample number sequence. The file is stored in EXCEL format. A check column in the worksheet contains a conditional test that the fields in the two sample number columns are identical.

The authors believe that all sampling, sample preparation, sample security and analytical procedures conform to industry best practice and are adequate to give a representative picture of the nature of the mineralized body and its host rocks. The QAQC program has not indicated any significant errors. The variation is random and is within laboratory error of ± 10%.

ITEM12: DATA VERIFICATION

All manual data entry is proofed on completion; where possible, conditional checks are built into the data entry spread-sheets to check for misallocation of data. Data merges are synchronized on a unique sample number and are checked with conditional codes. Drill-hole data is plotted in plan and section and viewed for spurious results. Recovery, Rock Quality Designation (RQD) and density data are plotted and viewed for internal consistency. Geological logs are printed and proof read by senior geologists. Page 52

Namiquipa Silver Deposit Technical Report

Further verification checks were conducted by T. Carew during and after a site visit in October. 2012. A field check of the collar locations of a number of randomly selected drill holes (5%) with a hand-held GPS unit was satisfactory. A randomly selected sample of nine drill holes (10%) from the database were checked against the original assay certificates and work orders for any miss-matches in assay data and drill hole intervals, and no errors were found. A check sample was selected at random from the core on site and independently submitted to ALS for assaying. The results were essentially identical to the original assay values for same interval sampled.

ITEM 13: MINERAL PROCESSING AND METALLURGICAL TESTING

No detailed metallurgical test work has been completed.

ITEM 14: MINERAL RESOURCE ESTIMATES

14.1 Resource Estimation Database

The database used for this study consists of 86 drill-holes as summarized in Appendix A and B. The drill data was collected solely by Minera Tasmania during 2011-2012 using diamond drilling techniques. Plan maps of the underground workings were scanned and digitized. 3D models of the workings and veins were created in GEMS (Figure 7). No underground assay data was used in the study.

14.2 Geological Modeling

Geological modelling and grade estimation was completed using MicroMODEL®, originally supplied by Pincock, Allen & Holt Inc. of Denver, Colorado and upgraded by Computer Aided Geoscience Pty Ltd.

14.2.1 Model Boundary

A three dimensional block model was defined over the project area with a southeast corner at 269,636 East, 3,229,628 North, 1,300 Elevation and an orientation of 025°TN. All survey data is in UTM format based on the WGS84 UTM Zone 13 Projection. The model dimensions are listed in Table 12.

14.2.2 Topography

A topographic mesh to cover the block model area was interpolated using a direchlet triangulation of hand- held GPS elevations collected during the ground magnetic survey. The accuracy of this data is generally ± 3 meters horizontal and 1 meter vertical. One meter contours generated from the triangulation compare well with the detailed surveying of the drill collars.

14.2.3 Geology

Assay data was manually coded with a three digit parameter to highlight changes in the style of mineralization that was being intersected by the drill-holes. The parameter used digit 1 to represent silver, digit 2 for lead and digit 3 for zinc. The nominal cut-offs applied to the parameter values of 0,1 and 2 are summarized in Table 13. These cut-off values were selected from an analysis of the sample statistics (see below). Under this system a code of 111 referred to high grade silver-lead-zinc whereas 221 indicated low grade silver-lead with high grade zinc. Code 000 was un-mineralized. Initial strict coding by assay value was manually overwritten in part to bulk out the mineralization zones based on geologic context.

Table 13 Cut-offs for Mineralization Coding

Metal Code 0 Code 2 Code 1 Ag Ag < 10 10 <= Ag < 40 Ag => 40 Pb Pb < 150 150 <= Pb < 1000 Pb => 1000 Zn Zn < 500 500 <= Zn < 2500 Zn => 2500

The interpretation of this data concluded:

1. The zinc mineralization had the most extensive geographic distribution, with lead occurring as discrete zones within the zinc, and silver superimposed on both but showing a greater preference for lead. Page 54

Namiquipa Silver Deposit Technical Report

2. A paragenetic sequence of zinc rich mineralization over-printed by lead and then by silver is suggested from the metal associations.

Figure 31 Proposed Paragenetic Sequence

3. High grade mineralization (code 111) was common close to the margins of the zinc distribution. 4. A sub-horizontal distribution of low grade silver with no lead or zinc (code 200) occurred over the top of the zinc distribution. 5. Internal mapping of the individual zones was not considered feasible at the current drill density.

A total mineralization boundary was mapped on each drill section that included all silver, lead and zinc mineralization (codes 1 or 2); this generally reflected the overall zinc distribution. Sectional interpretations of the total mineralization boundaries, as defined by drill-hole intercepts were cut by 10 meter bench slices and interpreted in plan view to define the extent and geometry of the mineralization. These plan interpretation was further zoned into conformable structural elements that matched the overall orientations of the America system - Zone 1, the Princesa North system - Zone 2, and the Princesa South system – Zone 5 (Figure 32). The rock model was then coded using a point in polygon routine to determine appropriate coding for each block in the model. Material outside the mineralization was coded as 999.

Within each of the zoned structural elements Indicator Kriging was used to map the distribution of high grades for each of silver, lead and zinc. Rock codes were then re-classified from 1, 3, 5 to 11, 13 or 15 where the indicator variable suggested that the probability of high grade material occurring was greater than 50% for silver, 60% for lead and 75% for zinc. The varying levels of confidence were based on visual validation of the indicator models against drill-hole plots.

The Indicator models were built using Ordinary Kriging working within geologically defined ellipsoids for each of the structural elements. Comparable search parameters were used for both the geologic definition as well as the grade interpolation.

14.3 Sample Statistics

A total of 20,319 samples have been assayed for the Namiquipa evaluation. The metal populations are generally log-normal and in the case of lead and zinc, distinctly multi-modal (Figure 33).

Silver has an average sample grade of 8 ± 56 g/t Ag within a data range from 0.2 to 2,500 g/t. The population is weakly bimodal with a threshold at around 150g/t Ag.

Lead is distinctly tri-modal with thresholds at approximately 35 and 65,000 ppm partitioning the population into waste (55% of data), mineralized (~45%) and anomalous (0.25%). The average grade is 938 ± 6459 ppm Pb.

Zinc is also tri-modal with thresholds at 100 and 10,000 ppm, partitioning the population into waste (45% of data), mineralized (~55%) and weakly anomalous (0.3%). In the mineralized sub-population zinc also displays a “break” in the distribution curve around 2500ppm.

Two silver samples were top cut to 1,770 g/t to force the resultant composite values into a standard log distribution. The samples were NAM-009 (211-212m) with a value of >10kg/t and NAM-047 (164.6-166) with value 3.54kg/t.

Lead and Zinc sample data were not cut as their cumulative frequency plot indicated a “lack” of anomalous results rather than the contrary.

14.4 Compositing and Statistics

The optimal composite length for this mineralization is calculated at 1.75 meters based on a Bench Height Analysis [BHA] study. The BHA progressively increases the composite length looking for the first significant reduction in variance that does not impact on the mean grade. This reduction in variance indicates that all the micro scale grade trends are incorporated into the basic sample unit (Table 16, Figure 34).

Drill data was down-hole composited to 2 meter intervals. A rock code was assigned to each composite based on its geographic location in the rock model. Summary statistics were calculated for each of the major elements (Table 17, Figure 35).

Silver is essentially a uni-modal log normal population with an arithmetic mean of 18.4 ± 60 within a data range from 0.2 to 1,335 g/t Ag. The log estimate of the mean is 16.8 g/t Ag.

Lead is also essentially uni-modal log normal. Its data range is from 2.4ppm to 11.98% and has a mean of 2,380 ± 7,015 ppm Pb. The log estimate of the mean is 2,315 ppm Pb.

Similarly, zinc is also essentially uni-modal log normal. The arithmetic average is 4,764 ± 12,922 within a data range from 3ppm to 16.27%. The log estimate of the mean is 4,403.

14.5 Variography

Total and down-hole log and linear variograms were calculated for mineralized composites of silver, lead and zinc. Although the linear variograms were poorly defined they were used to estimate the nugget effects and sills used in the Ordinary Kriging routines (Table 19). The log variograms were better defined and were useful for determining relative variances and ranges. The down-hole log variograms indicate an average down-hole width of the mineralization of around 30 meters. Indicator variograms suggest overall geologic continuity ranges of 75 to 100 meters (Table 18).

14.6 Grade Modeling

Block grades for silver, lead and zinc were interpolated using Ordinary Kriging acting within an oriented and scaled search ellipsoid. Grades were only interpolated within the interpreted mineralized outline.

The ellipsoids were defined with reference to geology and variography and scaled to suit the data distribution. A maximum search range of 125 meters was used (Table 20).

Composites were selected by sector search (6 sectors at 5 samples per sector) for a maximum of 30 samples. Blocks were interpolated using composites of comparable code. Point interpolations were made at the block centre using the same scaled ellipsoid to calculate the anisotropic distance weights. A minimum of four points was required for a determination.

14.7 Model Validation

The models were validated by visual comparison of model sections against drill-hole section plots. The tenor and orientation of the grade trends were considered to adequately reflect the original data.

This visual comparison is supported by statistical comparison of composite and model statistics (Tables 21) which show that the model grades are, on average, within 10-15% of the original data, that they have similar distributions and do not suffer too greatly from regression effects.

Visual checks were made of the block model at all stages of construction to verify that the appropriate flagging and domaining was undertaken. Visual checks comparing the drill-hole data to the estimated block grades was also undertaken. No obvious errors were noted.

14.8 Resource Classification

The resource is classified as Inferred. Although there is good continuity of the host geology and of the primary mineralized structures the grade variability is not well understood at the current drill spacing.

Within the CIM definitions an “Inferred Mineral Resource” is that part of a Mineral Resource for which quantity and grade or quality can be estimated on the basis of geological evidence and limited sampling and reasonably assumed, but not verified, geological and grade continuity. The estimate is based on limited information and sampling gathered through appropriate techniques from locations such as outcrops, trenches, pits, workings and drill-holes.

At Namiquipa the current drill spacing is sufficient to define broad geological continuity but not adequately define the grade trends and variability.

14.9 Resource Estimate

Geologic and grade continuity is inferred from similarity of geology, grade tenor and intercept thicknesses in adjacent drill-holes.

The resource summary was calculated as the tonnage weighted average of block grades whose values satisfied a variety of cutoff grade determinations. The deposit is open at depth. The resource is estimated at 4.6 million tonnes grading 103 g/t silver, 0.9% lead and 1.7% zinc at a cutoff grade of 154 g/t silver equivalent (Table 22). Silver equivalent grades were calculated using the 12 month average metal prices of US$31.50/oz Silver; US$0.89/lb Zinc; and US$0.92/lb Lead. Metal recoveries are not considered in this calculation. Sensitivity of this resource to cutoff grade is listed in Table 23.

The estimate of mineral resources may be materially affected by environmental, permitting, legal, title, taxation, socio-political, marketing, or other relevant issues.

14.10 Resource Estimate Risk

Given that sample collection and assay methods have been demonstrated to satisfy “industry best practice” the estimation risk is principally a function of the drill spacing. Macro scale geology and grade continuity is considered reasonable with broad zones of alteration and mineralization appearing in similar positions on adjacent sections. Meso scale grade continuity has yet to be substantiated.

ITEM 23: ADJACENT PROPERTIES

There are no adjacent properties.

ITEM 24: OTHER RELEVANT DATA

There is no other relevant data known by the authors

ITEM 25: INTERPRETATION AND CONCLUSIONS

Exploration methodology satisfied industry best practice.

QAQC of assay data indicates no significant concerns with grade accuracy or precision.

Modelling of the current drill distribution is a realistic approximation of the known metal distribution.

The resource of 4.6 million tonnes is a realistic estimate of the currently defined resource. This resource will change as infill drilling gives better definition of volumes and grade distribution.

ITEM 26: RECOMMENDATIONS

Future exploration at the Property should be focused in two areas:

1. Continued surface exploration by reconnaissance mapping and rock-chip sampling to identify new vein structures and mineralization elsewhere in the tenement area ;

2. Expansion of soil geochemistry grids to the north and south of the drilled area. The northern area exhibits strong characteristics for a deeper low sulphidation target capped by the upper ignimbrites. The southern area has had limited drill testing.

Estimated cost for this program is US$25,000.
