Brigadier Gold Limited (BRG-TSXV) Awaits Assay Results From Initial Drilling on the Incamayo Project in North West Argentina

TORONTO, ONTARIO--(Marketwire - March 29, 2011) - Brigadier Gold Limited (TSX VENTURE:BRG) (FRANKFURT:B7LN)

Bigadier Gold Limited's drilling contractor, Falcon Drilling (Barbados) Succursal Argentina, has, since the commencement of drilling in early March, completed approximately 641 metres of the planned 1500 metres on the Incamayo project in northwest Argentina.

An initial two holes have been completed to test the northern end of known mineralization on the property, with the first hole at -60° twinning CG97-07 (the best of nine holes drilled on the property in 1997 by Mansfield Minerals) and the second hole drilled at an angle of -50° to aid in defining further parameters to the mineralization.

The nine holes drilled by Mansfield were originally designed to test for economic grade mineralization below several well-mineralized sections encountered in trenches excavated during the previous exploration season. The Mansfield discovery hole (CG97-07), located 600 metres to the northeast of other mineralized holes, was reported in a Mansfield November 14, 1997, news release on Stockwatch (www.stockwatch.com) and is available on Sedar (www.sedar.com).

Brigadier's DDHCG11-01 has intersected massive to disseminated mineralization over a 53.0 metre interval from 106.3 metres to 159.3 metres in depth that matches the intersection as described in the original Mansfield reverse circulation hole, including a 7.0 metre interval from 106.3 to 113.3 metres containing numerous intervals of massive to semi-massive sulphide veins. Below 160 metres disseminated sulphides occur to the end of the hole at 298.5 metres with an interval of sulphide breccia from 288.35 to 289.33 metres.

The second hole completed (DDHCG11-02) was drilled at -50° to overcut DDHCG11-01, and predominantly intersected disseminated mineralization. Silicified breccia and variably silicified sandstone occur from 18.4 to 25.6 metres with strong vuggy iron oxidation. From 80.8 – 127 metres occurred variable silicification with breccias and up to 8% disseminated and massive sulphides. Vuggy goethitic oxidation is often associated with the breccias and silicification. Hole DDHCG11-02 did not cut the massive to semi-massive mineralization as seen in DDHCG11-01. This may be an indication that mineralization is improving with depth.

Results of the IP survey, which was commenced on the property by Argali Geophysica of Antofagasta, Chile in December, 2010, and was completed prior to the start of the drill program, show that the above holes are located at the southeastern edge of a large, untested chargeability anomaly.

As noted in Brigadier's February 8, 2011, news release on Stockwatch (www.stockwatch.com) and available on Sedar (www.sedar.com), a review of the 1997 drill program had determined that many of the 6 drill holes on the southern part of the property were oriented incorrectly to test the mineralized zones exposed at surface.

Hole DDHCG11-03 is located approximately 600 metres southwest of holes 1 and 2 and was drilled at -60° and designed to cut a series of mineralized (auriferous) silicified zones exposed on surface and in trenches. This style of mineralization differs markedly from that seen in DDHCG11-01 and 02 and probably represents a different mineralizing event.

DDHCG11-03 intersected several zones of mineralization comprising quartz stockworks with ubiquitous iron oxides after sulphides, the most important being from 0 to 4 metres, 17.2 to 27.6 metres, 32.4 to 40.3 metres and 69.1 to 80.0 metres. From 82.5 to 83.9 metres and from 106.5 to 109.2 metres occur numerous narrow veins of massive to semi-massive sulphides. This hole is located in an area where 4 Mansfield holes are believed to have been drilled to test surface mineralization.

Assay results on the above holes are pending and will be reported once received. Drilling is continuing apace.

Malbex Reports Additional Higher-Grade Mineralization at Del Carmen Norte, Including 46 m at 3.31 g/t Gold and 25.2 g/t Silver

TORONTO, ONTARIO--(Marketwire - March 25, 2011) - Malbex Resources Inc. (TSX VENTURE:MBG) today announced results from three drill holes, including additional higher-grade results, from the Rojo Grande target on the Company's Del Carmen gold-silver project in San Juan province, Argentina. Hole DDHC-11-046 was collared approximately 80 metres (m) southeast of hole DDHC-11-042 (103 m at 2.84 g/t gold, PR Feb. 22, 2011) and has expanded the higher-grade mineralization recently discovered in this part of the Rojo Grande silicified ledge. Two significant zones of mineralization were encountered in hole 46:


DDHC-11-046: 46 m at 3.31 g/t gold and 25.2 g/t silver

and 132.65 m at 2.10 g/t gold and 10.8 g/t silver

including 23 m at 5.51 g/t gold and 20.4 g/t silver

and including 34 m at 3.32 g/t gold and 17.6 g/t silver


The higher-grade zones at Rojo Grande occur in proximity to a dacite intrusion identified during the recent visit to the property by Dr. Richard Sillitoe, a consultant known for his expertise in epithermal and porphyry systems. While the core of the dacite intrusion is marked by barren quartz-kaolinite, the alteration grades outward into quartz-alunite alteration and silicification with hydrothermal brecciation and intense silicification affecting both the dacite margin and surrounding andesitic wall rocks. While mineralization is typically concentrated in the silicified rocks, powdery quartz-alunite altered rocks are mineralized locally at Rojo Grande.


The recent drilling has also extended the apparent depth of oxidation at Rojo Grande from surface to at least 220 m vertical depth, which is encouraging from a metallurgical standpoint. Preliminary metallurgical testing of core from Rojo Grande and Naciente Quebrada Pedregosa targets at Del Carmen Norte shows good potential for heap leach cyanidation treatment, with gold recoveries averaging 76.5% (PR Jan. 20, 2011).


"The results of holes 42 and 46 have improved our geologic model, and our ability to target higher-grade zones within the Rojo Grande ledge," said Tim Warman, President and CEO. "Rojo Grande is delivering everything we could ask for – consistent gold-silver mineralization with higher-grade, near-surface zones, generally shallow to non-existent overburden, encouraging metallurgy, and the structure remains open at depth and to the southwest. We're currently awaiting the results for the scissor hole (49) on this section in order to better understand the geometry of the higher-grade zones discovered in holes 42 and 46, and will be looking to infill this area before the end of the current drilling season."


Holes DDHC-11-043 and -044A, were completed at the northeastern margin of the Rojo Grande target, close to where the silicified ledge is truncated by erosion, approximately 220 m northeast of holes DDHC-11-042 and -046. DDHC-11-043 intersected approximately 80 m of vuggy silica, silicification and minor quartz-alunite alteration that contained several short zones (4-12 m) with >0.2 g/t gold, mainly associated with hydrothermal breccias. DDHC-11-044A passed through approximately 56 m of silicified dacite before entering quartz-kaolinite altered andesite. No significant mineralization was encountered in 44A.


With today's release, 12 holes totalling 2,264 m have been reported for the 2010/2011 field season at Del Carmen Norte (Figure 1). One drill rig continues to delineate the Rojo Grande target, which is still open at depth and to the southwest, while the second rig is attempting to test the controlled source audio-magneto-telluric (CSAMT) resistivity anomalies to the southwest of Rojo Grande at Cerro Amarillo. The drilling at Cerro Amarillo is proving challenging, and our drilling contractor is currently making a fourth attempt to reach the target depth of 500 m to test this large geophysical target.

Del Carmen results


DDHC-11-043 (azimuth 300°, dip 60°) and DDHC-11-044A (azimuth 120°, dip 60°) were drilled from the northeasternmost platform at Rojo Grande (Figures 1 and 2) close to where the silicified ledge is truncated by erosion, approximately 220 m northeast of holes DDHC-11-042 and -046. Hole 43 passed through approximately 10 m of overburden before intersecting strongly silicified dacite porphyry with local bands of hydrothermal breccia and quartz-alunite alteration which are succeeded below by silicified andesitic volcanic breccias, flows and tuffs. Vuggy silica textures and variable degrees of hematite, goethite and jarosite coating fractures are observed in the silicified zone, which ends at about 85 m depth. The silicified rocks are succeeded by clay altered (quartz-kaolinite) andesite. The hole was stopped at 158.5 m after passing through a narrow fault zone currently interpreted to strike oblique to the section.


Although drilled from the same platform as 43, hole DDHC-11-044A struggled to pass through more than 27 m of overburden. This was the second attempt to drill to the southeast on the same platform. Hole 44 was aborted at 45 m due to drill difficulties. Hole 44A intersected silicified dacite porphyry similar to that in 43 and then passed through an approximately 20 m wide fault zone before entering quartz-kaolinite altered andesite at 58 m depth. The hole was terminated at 221 m in quartz-kaolinite altered andesite.


DDHC-11-046 (azimuth 330°, dip 70°) was collared about 80 m southeast of holes 42 and 40 (on the same section) to test for the continuation to the southeast of the high grades intersected in 42. Two significant intervals of mineralization are present. The upper begins effectively at surface (below 6 m of overburden) but due to locally poor recoveries, which includes 8.5 m of zero recovery, the most reliable interval begins at 18 m depth and consists of 46 m of silicified and quartz-alunite altered dacite porphyry grading 3.31 g/t gold and 25.2 g/t silver. The hole then enters a zone of quartz-kaolinite altered porphyry lacking mineralization, before re-entering quartz-alunite altered and silicified porphyry hosting a wide zone of gold-silver mineralization (132.65 m grading 2.1 g/t gold and 10.8 g/t silver). Discrete higher-grade intervals within the longer lower intercept include 23 m grading 5.51 g/t gold and 20.4 g/t silver and 34 m grading 3.32 g/t gold and 17.6 g/t silver. The hole was terminated at 238.65m within the mineralized zone after passing through a short fault zone.


Significant mineralized intercepts in the most recent holes are tabulated below.


There has been insufficient drilling to date to reliably calculate true widths for the mineralized intercepts tabulated above.


About Del Carmen Norte and Rojo Grande


Rojo Grande consists of prominent reddish weathering silicified outcrops on the northern flank of the massif of high sulphidation hydrothermal alteration at Del Carmen Norte. Silicified outcrops combined with geophysical data identify a shallow-dipping northeast-southwest striking, near-surface silicified ledge at Rojo Grande measuring approximately 800 m long by up to 300 m wide. Previous significant intersections at Rojo Grande include:


2009/2010 Field Season


DDHC-10-017: 41 m grading 1.18 g/t gold and 31.2 g/t silver


DDHC-10-018: 15 m grading 1.07 g/t gold and 27.3 g/t silver


DDHC-10-020: 124.5 m grading 0.57 g/t gold and 8.8 g/t silver


DDHC-10-031: 35 m grading 0.94 g/t gold and 13 g/t silver


DDHC-10-032: 142.15 m grading 0.88 g/t gold and 13.7 g/t silver including 40.15 m grading 1.45 g/t gold and 19.6 g/t silver


2010/2011 Field Season


DDHC-10-033: 70 m grading 0.46 g/t gold and 12.8 g/t silver


DDHC-10-034: 73 m grading 0.74 g/t gold and 17.4 g/t silver including 16 m grading 0.97 g/t gold and 20.0 g/t silver DDHC-10-035: 49 m grading 1.41 g/t gold and 3.2 g/t silver including 8 m grading 7.08 g/t gold and 11.6 g/t silver DDHC-10-038: 22 m grading 0.41 g/t gold and 8.78 g/t silver and 24 m grading 0.90 g/t gold and 13.25 g/t silver DDHC-10-039: 86 m grading 0.77 g/t gold and 9.3 g/t silver


DDHC-10-040: 19 m grading 0.70 g/t gold and 4.1 g/t silver including 10 m grading 1.14 g/t gold and 5.1 g/t silver DDHC-10-042: 103 m grading 2.84 g/t gold and 6.4 g/t silver including 29 m grading 9.61 g/t gold and 10.1 g/t silver with 5 m grading 48.34 g/t gold and 15.4 g/t silver


Mineralization at Rojo Grande is generally hosted by vuggy silica and massive silicification with red-brown staining due to fine-grained hematite, goethite and jarosite as disseminations and veinlets. The silicified outcrops at Rojo Grande are interpreted to be part of a sub-horizontal ledge (sheet) formed by silicification and quartz-alunite alteration of andesitic and dacitic breccias within the strongly advanced argillic (kaolinite) to argillic (illite) altered tuffs and fine-grained flows that dominate the andesitic volcanic sequence. The silicification appears to be preferentially associated with a probable subvolcanic dacite porphyry and its brecciated margins.


About the Del Carmen work program


The 147 km2 Del Carmen concession package is located near the southern end of the El Indio Gold Belt, and hosts the Del Carmen Norte and Del Carmen Sur high sulphidation epithermal gold-silver systems. The Del Carmen Norte hydrothermal alteration system covers approximately 9 km2. A second, less exposed, high sulphidation epithermal system occurs at Del Carmen Sur some 5 km to the south of Del Carmen Norte.


Del Carmen Norte consists of a strongly altered, sub-horizontal sequence of andesitic volcanic rocks that is cut by numerous faults. Volcanic breccias appear to be selectively silicified with silicification hosting mineralization sandwiched between less favourable argillic altered volcanic layers. Steep faults have strongly influenced hydrothermal fluid flow within the volcanic sequence. High-sulphidation alteration is therefore zoned outward from the combination of both lithological and structural controls on silicification. Controlled source audio-magneto-telluric surveying (CSAMT) in the previous field campaign identified elevated resistivity coincident with silicified rocks at Rojo Grande. Other larger CSAMT resistivity anomalies to the southwest are directly associated with steam-heated siliceous alteration at high elevations at Cerro Amarillo but continue to the depth limits of detection of the survey (roughly 500 m vertically).


In addition to Rojo Grande, other zones of vuggy silica and other styles of silicification, and enargite-bearing quartz veins on surface were drill tested in the 2009/2010 field campaign. The current drilling campaign at Del Carmen Norte is focused on defining the extent of gold-silver mineralization at Rojo Grande, testing CSAMT resistivity anomalies (including the large anomaly between Rojo Grande and Cerro Amarillo), and following up on encouraging initial drill results from Naciente Quebrada Pedregosa south of Cerro Amarillo.


Technical information


Diamond drill hole samples consist of core that is sawn in half by electric saw on site. Core samples are sealed in new plastic bags, which are inserted into rice sacks for transport by Malbex personal or commercial trucking service to ALS Global prep lab in Mendoza. All samples are crushed and pulped and powders sent by ALS to one of their laboratories (typically La Serena, Chile or North Vancouver, BC). Fire assay for gold is conducted on 30 gram (g) pulps with atomic absorption finish. Over limits (>10 g/t gold) are fire assayed with gravimetric finish. In addition, all samples receive multi-element analysis including silver by ICP after aqua regia digestion and mercury by cold vapour atomic absorption.


Malbex's quality assurance-quality control (QA-QC) program consists of the insertion in every 20 samples of at least one certified standard of known gold content, one blank (sample known to consist of very low levels of gold to ensure adequate cleaning of the sample preparation equipment between samples) and one field duplicate. Samples of significant drill intercepts will be sent to two additional independent laboratories to verify gold and silver analyses when necessary. Metallic screen fire analyses for gold will also be run regularly on discovered mineralization as an additional QA-QC check. The half core remaining after sampling is stored in a Malbex-run facility in San Juan for verification and reference purposes.

Lumina Copper to Reorganize Into Two Companies: Lumina Copper Corp. and Lumina Royalty Corp.

VANCOUVER, BRITISH COLUMBIA--(Marketwire - March 24, 2011) - Lumina Copper Corp. (TSX VENTURE:LCC) ("Lumina" or the "Company") is pleased to announce that the Company intends to complete a strategic reorganization of its business. Lumina's royalty interests and certain non-core assets will be transferred to a newly incorporated company to be called Lumina Royalty Corp. Shareholders of the Company will receive shares in Lumina Royalty Corp. in proportion to their shareholding in Lumina.

Lumina Royalty Corp. will hold the following key assets:

A 1.5% Net Smelter Return ("NSR") royalty on Teck Resources Ltd's Relincho copper/molybdenum advance development project located in Region IV, Chile. A 1.5% NSR royalty on Los Andes Copper Limited's Vizcachitas copper/molybdenum project located in Region V, Chile. A 1.08% NSR royalty on Lumina Copper Corp.'s Taca Taca copper/gold/molybdenum project located in Salta Province, Argentina. A copper royalty, including the advance royalty payments (excluding the May 2011 US $4 million payment), on Coro Mining Corp's San Jorge copper/gold/molybdenum project located in Mendoza Province, Argentina. A 1.5% NSR royalty on all metal production, other than copper, on Coro Mining's San Jorge copper/gold/molybdenum project.

The Taca Taca copper/gold/molybdenum project will remain in Lumina Copper Corp. along with the necessary cash to fund the Company's ongoing exploration and development program.

It is intended that, as part of the reorganization, Lumina's current shareholders will receive shares of Lumina Royalty Corp. by way of a return of capital on their shares of the Company. The return of capital will require the approval of the Company's shareholders at a shareholders meeting, which the Company expects to hold by the end of May 2011. Lumina has no plans to seek a public listing for Lumina Royalty Corp.'s shares in the near term.

The Company is completing the reorganization in order to focus on the development of its Taca Taca copper/gold/molybdenum project. The Taca Taca project, comprising approximately 2,500 hectares, is located in the Puna region of north western Argentina in Salta Province, approximately 230 kilometres west of the provincial capital of Salta and 90 kilometres east of the world's largest copper mine, Escondida. In January, the Company announced that it had initiated a 43,000m drill program and a comprehensive engineering and metallurgical testing program at Taca Taca. Both programs are expected to be completed by the end of 2011.

On October 9, 2008, Lumina announced it had received an independent National Instrument 43-101 ("NI 43-101") compliant mineral resource estimate for the Taca Taca project that at a 0.4% copper equivalent cut-off contained inferred mineral resources of 841 million tonnes grading 0.64% copper equivalent, containing 8.71 billion pounds of copper, 2.97 million ounces of gold and 333.70 million pounds of molybdenum(1).

Additional information on the Taca Taca project, including the NI 43-101 technical report "Amended Taca Taca Technical Report" dated January 22, 2010 by Robert Sim, P.Geo., can be found on Lumina's website (www.luminacopper.com) and on SEDAR (www.sedar.com).

Leo Hathaway, P.Geo., Vice President, Exploration and the Qualified Person (as defined by NI 43-101) for the Taca Taca project, has reviewed and approved the content of this press release.

(1) The copper equivalent cut off grade used in the calculation of the mineral resource estimate was determined using US$1.50 / lb copper, US$600 / oz gold and US$6.00 / lb molybdenum and was not adjusted for metallurgical recoveries as these remain uncertain. The formula used in the calculation was as follows: CuEQ = Cu% + (Au g/t x 0.583) + (Mo% x 6).

Barrick Delivers Over $9 Billion in Economic Value in 2010

Positive Economic Impact Features in New Edition of Beyond Borders TORONTO, ONTARIO--(Marketwire - March 23, 2011) - Barrick Gold Corporation's role as an engine of economic development is featured in the latest edition of Beyond Borders, which documents the company's contribution of over $9 billion to the economies of its host countries in 2010. This figure includes local and regional purchases, payments to governments and employees, as well as over $31 million in community programs to improve quality of life.

"Barrick's operations are a major source of economic activity and contribute to long-term development," said Peter Sinclair, Vice-President, Corporate Social Responsibility. "In a number of countries, the positive economic and social impact has been documented, including declining poverty rates, higher literacy and education levels, and the emergence of new businesses. We also make significant social investments, which support our global strategy of ensuring the benefits of our business are shared with our host communities."

The socio-economic impact of Barrick's mines in Argentina and Peru was the subject of two recent studies conducted by Consultura Malthus, a Chilean consultancy firm. The studies described trends such as declining poverty rates, economic diversification and enhanced literacy levels. In the district of Jangas, located closest to the Pierina mine in Peru, the percentage of people living in poverty was 80 per cent in 1993, dropping to 31 per cent in 2007, well below the national average. Illiteracy rates also declined dramatically from 56 per cent to 31 per cent during the same period.

According to a second study, the Veladero mine in Argentina accounts for 23 per cent of the gross domestic product in the province of San Juan and "has created a more stable and diversified economy in the province." The study cited positive employment trends, sectoral activity and growth in local tax revenues as "clear signals of Veladero's direct and indirect impact." Social conditions in San Juan also improved significantly in such areas as poverty and infant mortality rates.

In Tanzania, African Barrick Gold (ABG) has invested over $1.6 billion of capital in the country to date. The majority of revenue generated from ABG's operations — about 70 per cent — remained in Tanzania in 2009. That year, ABG spent $69 million on goods and services procured from Tanzanian-owned companies, and a further $1 million on skills development programs.

In recession-battered Nevada, Barrick employs more than 4000 people, providing sustaining wages and job security. The company is one of the largest private employers in rural Nevada. In the last five years, Barrick has invested more than $2 billion to sustain and expand its Nevada mines. In March, Barrick prepaid $101 million in Net Proceeds of Minerals taxes to the state, based on estimated 2011 operating results from its Nevada mining properties.

This edition of Beyond Borders also profiles a $75 million investment by the Pueblo Viejo Dominicana Corporation (PVDC) to fund a large-scale environmental clean-up effort at the site of the Pueblo Viejo project in the Dominican Republic. The company is doubling its original $37.5 million contribution to the rehabilitation project, which was necessitated by the improper closure of a former mine on the property by a previous owner in 1999. PVDC, jointly owned by Barrick (60 per cent) and Goldcorp (40 per cent), is the company that operates Pueblo Viejo. Other features: Barrick named to Dow Jones Sustainability Index for third year Barrick joins Voluntary Principles on Security and Human Rights One year later: Barrick helps Chile rebuild after earthquake Sun-dried tomatoes big business for Argentina's farmers Fighting tropical diseases in the Dominican Republic Barrick supports Western Shoshone language preservation program Community relations at Australia's Super Pit mine

Beyond Borders is a report to stakeholders produced and published by Barrick Gold Corporation, featuring the latest news and updates on Barrick's social, environmental, safety and economic development programs.

Wealth Commences Discovery Drilling Campaign on Its Bororo Nuevo Uranium Property, San Jorge Basin, Argentina

VANCOUVER, BRITISH COLUMBIA--(Marketwire - March 23, 2011) - Wealth Minerals Ltd. (the "Company" or "Wealth") (TSX VENTURE:WML)(FRANKFURT:EJZ), is pleased to announce that diamond drilling has commenced on the Company's 100% owned Bororo Nuevo property ("BN") located in Chubut Province, Argentina. The diamond drill program now underway at BN will consist of a minimum of 30 holes (approximately 2,000 metres) targeting on- and near-surface uranium mineralization at several high-priority target zones - the Alpha, Beta, Gamma and Delta zones.


Bororo Nuevo Exploration Highlights


9 large mineralized zones discovered on only 12% of the overall BN property package.

Uranium values from 608 surface rock samples average 2.41 lbs/ton U3O8 (0.102% uranium)

Continuous chip sampling results of 7.33 lbs/ton U3O8 (0.311% uranium) over 10.0 metres and 4.01 lbs/ton U3O8 (0.170% uranium) over 12.5 metres. 25+ year old drill cuttings assayed 4.22 lbs/ton U3O8 (0.179% uranium)

Extensive un-explored property package in what has been described as the last and least-explored sandstone-hosted uranium district in the world.


Bororo Nuevo Property Overview


The Bororo Nuevo property is the flagship of the Company's five uranium properties in the productive San Jorge Basin, which is host to the past-producing Cerro Condor and Los Adobes deposits as well as the 10.3 million pound U3O8 Cerro Solo uranium deposit. The San Jorge Basin lies within the Patagonian Provinces of Santa Cruz and Chubut and is readily accessible via an all-season paved road and a network of well-maintained gravel roads. The Company currently owns, or has the exclusive right to acquire, 76 'minas' and 'cateos' (concessions) that total approximately 600,000 hectares (6,000 square kilometres) representing the largest land position in the San Jorge Basin.


The BN property consists of 4 minas and 6 cateos that total approximately 35,500 hectares (355 square kilometres). To date, nine large zones of mineralization have been discovered within a uranium fairway measuring 12 by 4 kilometres and less than 12% of the property has been mapped and prospected. The stratigraphy is known to be productive and the continued success of surficial exploration programs at BN clearly highlights the uranium-rich and underexplored nature of the San Jorge Basin.

ARGENTEX RECEIVES PRELIMINARY ECONOMIC ASSESSMENT RESULTS ON PINGUINO'S NEAR-SURFACE SILVER-GOLD OXIDE RESOURCE

VANCOUVER, March 22 /CNW/ - Argentex Mining Corporation ("Argentex" or "the Company") (TSXV: ATX) (OTCBB: AGXM) has received the results of a positive NI 43-101 Preliminary Economic Assessment ("PEA") report on the near-surface silver-gold oxide resource from its Pinguino project located in Santa Cruz province, Patagonia, Argentina. The portion of the mineralized system assessed in the PEA is limited to the indicated and inferred silver-gold oxide resource previously identified by Moose Mountain Technical Services in its National Instrument (NI) 43-101-compliant August 2009 report titled "Resource Estimate for the Pinguino Silver, Zinc, Indium, Lead, Gold Occurrence (the "2009 Technical Report"), a copy of which has previously been filed on SEDAR. The company had been focused on drilling the polymetallic sulphide mineralization at Pinguino through until late 2009, at which time Argentex began to focus on the property's near-surface silver-gold oxide horizon. Argentex intends to use data from silver-gold discoveries made in 2010, as well as results from the current 2011 drill program in progress, to update both the PEA and the 2009 Technical Report later this year. Additional veins that have been tested since preparation of the 2009 Technical Report contain significant intersections of high-grade silver and remain open along strike and to depth. The PEA is based upon an update of the 2009 Technical Report (see table below), which used results from only nine of the 51 veins identified to date on the Pinguino property, and is estimated to represent only seven line kilometres of vein strike length out of a combined strike length in excess of 75 line kilometres discovered to date. The update used the 2009 published interpolation parameters but divided the resource into oxide and sulphide zones. Data from 2010 and 2011 has not yet been incorporated. Summary of Estimates: Base Case using $US1,036 oz Au and $US16.96 oz Ag: ● Internal Rate of Return (IRR) 44% ● Mine Life 8 years ● Net Cash Flow US$ 29.7MM ● Net Present Value (NPV) 5% Discount Rate US$ 21.9MM ● Payback 23 months ● Average Annual Production ~657,000 oz Ag, ~6,400 oz Au ● Capital Costs US$ 20.7MM A Summary of Returns using different gold and silver prices is as follows:

"The completion of this initial PEA is an important first step for Argentex as we continue to evaluate strategic avenues of building shareholder value within the prospective Pinguino property. It confirms our belief that the shallow oxidized mineralization at Pinguino is capable of generating attractive rates of return and cash flow in support of continued mine development and resource expansion within the property's very large mineralized system," said Ken Hicks, P.Geo, President of Argentex. "In addition, we believe that the positive results from the 2010 exploration program, which are not included in the PEA, suggest that Pinguino holds the potential for a significantly larger resource. The focus of our current 2011 exploration program, which commenced on January 24, 2011, is to further evaluate the numerous extensions of known mineralization that remain open along strike and at depth and offer excellent opportunities for resource expansion. We believe 2011 will be another year of discovery and resource growth and look forward to continuing to build value for our shareholders."


The PEA covers nine of the 51 mineralized veins identified to date at Pinguino. Additional veins that have been tested since preparation of the 2009 Technical Report contain significant intersections of high-grade silver and remain open along strike and to depth. The PEA oxide Base Case relies on the Indicated and Inferred Resources shown below:


Oxide Resource: Summary of Designed Pit*1 Delineated Resource:


The above Resource and Cash Flow results (using gold and silver prices of US$1,036 per oz Au and US$16.96 per oz Ag for the base case, respectively) assume the development of an open pit mine comprised of a 3,000 tonne per day heap leach operation from the oxide portion of the deposit and would produce a silver/gold doré onsite at the Pinguino property. Discovery of additional oxide mineralization proximal to the identified resource, as well as polymetallic sulphide mineralization, represent opportunities to expand the operation and Argentex plans to make these the subject of continuing study.


The Pinguino property is host to two distinct categories of mineralization, distinguished by their differing mineralogical character and depth from surface. The first category is a thick horizon of oxide material, enriched in silver and gold, located within the first 50 meters from surface. Below this oxide material, primary unoxidized mineralization forms the second category and occurs from approximately 50 meters to a maximum tested depth of 400 meters below surface. This primary material is composed of both quartz-rich silver-gold and sulphide-rich polymetallic mineralization, as there are two different types of veins within the Pinguino property.


Polymetallic sulphide mineralization has been found within multiple veins in the core of the property, with vein thicknesses of up to 10 meters in width and extensive strike lengths. Argentex believes that these veins are open in all directions with excellent potential for expansion. This type of mineralization is considered a significant opportunity to expand the operation and will be the subject of ongoing exploration.


The mine plan envisaged would be a contract operation with initial mining within surface-exposed mineralization. Sequential mining of the separate veins in the deposit will give an opportunity for short hauls and backfilling of mined-out pits.


Moose Mountain Technical Services (MMTS), a qualified independent consultant to Argentex, prepared the NI 43-101-compliant PEA. Key recommendations from the MMTS report, with respect to the next phases of mine and metallurgical engineering, are under review and plans for implementation are being developed.

Argentex Mining Corporation is an exploration company focused on the discovery of silver, gold and polymetallic deposits on its advanced late-stage exploration projects in the Patagonia region of southern Argentina.


In 2011, through an extensive targeted exploration program, Argentex is currently advancing its highly prospective projects, specifically its 100%-controlled Pinguino project, located in Santa Cruz province. An early 2011 drill program of approximately 17,000 meters is underway at Pinguino, where Argentex plans to drill test the extents of previously identified high-grade silver targets discovered in 2010. More than 6,300 meters of the proposed 17,000-meter program have been completed to date. The new discoveries being drill tested include the Tranquilo and Luna veins at Pinguino, which returned high-grade results in previous drill programs, including 6.0 meters of over 2,400 g/t silver and 0.22 g/t gold and 6.4 meters of 486.6 g/t silver and 1.91 g/t gold. More than 51 individual veins have so far been discovered at Pinguino, with a combined strike length in excess of 75 line kilometers. Only a small percentage of veins and potential targets have been drill tested in the 42,300 meters of drilling completed at Pinguino to date.


Argentex's 10,000-hectare Pinguino property is located in Argentina's Patagonia region, within the Deseado Massif of Santa Cruz province. Pinguino is easily accessible, situated approximately 400 meters above sea level in low-relief topography. An existing system of all-weather roads provides year-round access to the property.


In total, Argentex owns 100% of the mineral rights to more than 35 projects located within approximately 307,981 acres (124,636 hectares) of highly prospective land located in the Santa Cruz and Rio Negro provinces of Argentina. Shares of Argentex common stock trade under the symbol ATX on the TSX Venture Exchange and on the OTCBB under the symbol AGXM.
