More Bonanza Gold Intercepts from Calandria Norte Las Calandrias Project, Southern Argentina

Mariana Resources Ltd (‘Mariana’ or ‘the Company’), the AIM quoted exploration and development company focused in Argentina and Chile, announces further encouraging results from the third drilling campaign at the Calandria Norte prospect (‘Calandria Norte’), one of
several key target areas at the Company’s 100% owned flagship Las Calandrias Gold-Silver
Project (‘Las Calandrias’), located in the prospective Deseado Massif gold-silver district in
Southern Argentina

Overview:

• Results from first 16 holes from infill and exploratory drilling campaign at Calandria Norte indicate potential for developing significant high grade gold-silver mineralisation within an extensive rhyolite dome-hosted stockwork zone;

o Four additional bonanza grade vein-breccia intersections at La Calandria Vein
o Best intersection of 11.5m @ 10.5 g/t Au and 53 g/t Ag from 85m, including 2.40m @ 43.0 g/t Au & 218 g/t Ag from 89.3m (CND125)
o Other highlights include 12m @ 8.0 g/t Au and 9 g/t Ag from 101m including 0.6m @ 123.0 g/t Au & 93 g/t Ag (CND122) and 28.6m @ 4.0 g/t Au and 17 g/t Ag from 77.4m including 0.45m @ 140.5 g/t Au & 312 g/t Ag (CND123)

• Infill and exploratory drilling planned on La Calandria Vein which extends for 400m strike and is open at depth to the WSW and ENE
• Shallow scout drilling of covered target north of La Calandria has discovered La Morena Vein with 0.8m @ 12.0 g/t Au and 32 g/t Ag from 89.7m (CND146) - follow up drilling planned
• Assays pending from 11 other Calandria Norte holes
• Two rigs currently testing new Induced Polarisation (‘IP’) targets in the El Nido Area
(6,000m minimum) – first results expected February 2011

Commenting today, Chairman John Horsburgh said, “These results indicate resource potential at Calandria Norte with further exploratory and infill drilling planned. In the meantime, two drill rigs are currently testing multiple targets in the El Nido area with initial results expected
next month.”

Mariana has drilled 53 diamond drill holes at Calandria Norte to date for a total of 7,706m
(see news release dated 15 October 2010). The last programme in 2010 consisted of 44 holes for a total of 6,175 metres. Of these, 22 were at La Calandria Vein, seven at La Morena Vein target and four at other targets. Results have been received for 20 La Calandria Vein holes and two of the seven La Morena holes, with remaining assays pending.

Hole locations, longitudinal section, cross sections are shown on the drill plans and a summary of intersections is included in the table at the bottom of the release.

La Calandria Vein

High grade gold-silver vein-breccia intersections occur within a sulphidic stockwork which
extends over a 400m strike and approximately 20-100m in width. The longitudinal gm-m Au
(gm Au x metres) section shows +10gm-m Au mineralisation commencing at 30-90m below surface, open to the WSW and ENE along 400m strike and at depth. The vein system consists
of NE trending vein-breccias (up to 1.5m wide) dipping steeply NW and sulphidic stockwork
veinlets striking ENE dipping steeply SE. Bonanza gold mineralisation occurs at the intersection of the breccias and hanging wall stockwork veinlets along the vein trend. Apart from two deeper holes (CND 149 and 150 – assays pending), La Calandria Vein trend is untested beyond a depth of 150m. Further exploratory and infill drilling of the Calandria Norte vein-breccia trends will follow drilling at El Nido (30% complete).

Subject to follow-up drilling and modelling at Calandria Norte, the scope of the preliminary
resource estimation for Calandria Sur could be expanded to include Calandria Norte. The completion of the Calandria Sur resource study is expected Q2 2011.

Central Bonanza Zone

Holes CND122 and CND123 indicate reasonable continuity in the Central Bonanza Zone, with intersections of 0.6m @ 123 g/t Au and 93 g/t Ag from 104.6m and 0.45m @ 140.5 g/t Au and 312 g/t Ag from 79.9m, respectively. A central core of five intersections of +100gmm Au mineralisation strikes 150m and occurs in a vertical range between 50m to 135m below
surface. The high grade mineralisation appears to terminate about 150m below surface in the
central zone, e.g. CND124 intersected a sulfide breccia with no significant gold mineralisation 20m below bonanza hole CND61 (0.95m @ 139.5 g/t Au and 107 g/t Ag from 120.4m). In this case, the favourable intersection of the vein-breccia with stockwork veinlets is not present. However, adjacent deeper hole CND127 with 9.9m @ 1.5 g/t Au from 141m indicates mineralisation can persist to 150m below surface in the central zone.

Central Zone intersections of interest include:

• CND122 - 12m @ 8.0 g/t Au and 9 g/t Ag from 101m including 0.6m @ 123.0 g/t Au
& 93 g/t Ag from 104.6 m
• CND123 – 28.6m @ 4.0 g/t Au and 17 g/t Ag from 77.4m including 0.45m @ 140.5
• CND125 – 11.5m @ 10.5 g/t Au and 53 g/t Ag from 85m including 2.40m @ 43.0 g/t
Au & 218 g/t Ag from 89.3
• CND126 - 17m @ 1.0 g/t Au 2.7 g/t Ag from 110m
• CND127 - 9.5m @ 1.7 g/t Au from 103m
• CND134 - 7.7m @ 4.1 g/t Au from 77.3m

Previously announced Central Zone bonanza intersections are:

• CND 45 - 4.0m @ 75.9 g/t Au and 70 g/t Ag from 92.5m
• CND 46 - 4.5m @ 101.8 g/t Au and 70 g/t Ag from 81.5m
• CND60 - 0.44m @ 30.5 g/t gold & 145 g/t silver from 91.7m
• CND61 - 5m @ 34.1 g/t Au and 32 g/t Ag from 119m.
• CND64 - 0.75m @ 33.1 g/t Au & 41 g/t Ag from 70.4m

Lateral Zones

The drilling indicates that the vein-breccia mineralisation (+25gm-m Au) is open to the WSW
(CND131 and 132) and ENE (CND137). An encouraging intersection was obtained in CND131 - 7.0m @ 5.6 g/t Au and 6 g/t Ag from 120.5m, including 1.0m @ 11.5 g/t Au and 10.3 g/t Ag from 125m. A bonanza intersection was returned for the westernmost hole, CND132 - 0.8m @ 90.2 g/t Au and 198 g/t Ag from 132.1m, 120m below surface and 50m below low grade mineralisation in CND07 (5.2m @ 0.6 g/t Au, from 87.1m). The deepest and easternmost intersection was 13.5m @ 3.0 g/t Au and 7 g/t Ag from 159m, (CND137), 150m below surface.

Lateral Zone intersections of interest:

• CND129 – 8.0m @ 2.2 g/t Au and 2 g/t Ag from 91m including 0.65m @ 21.1 g/t Au & 18 g/t Ag from 92.95m
• CND131 - 7.0m @ 5.6 g/t Au and 6 g/t Ag from 120.5m
• CND132 – 0.8m @ 90.2 g/t Au and 198 g/t Ag from 132.1m
• CND 137 - 13.5m @ 3.0 g/t Au and 7 g/t Ag from 159m including 1m @ 15.5 g/t Au & 20 g/t Ag from 168m.

La Morena Vein

La Morena is a new concealed target located in the northern part of Calandria Norte rhyolite
dome. Seven shallow scout holes tested a NE trending IP anomaly parallel to La Calandria
bonanza vein, 270m to the north. Chalcedonic silica-sulphide vein-breccia was intersected along a 350m strike with the two holes received indicating gold mineralisation:

• CND144 – 1.7m @ 1.6 g/t Au and 7 g/t Ag from 58.8m
• CND146 – 0.8m @ 12.0 g/t Au and 32 g/t Ag from 89.7m

Las Calandrias Project Background

Las Calandrias comprises multiple zones of gold mineralisation hosted by rhyolite domes over a 10.5 km2 area. In 2009, 16 scout holes (1,763m) tested the Calandria Norte veinbreccia and Calandria Sur dome breccia targets where significant gold mineralisation was discovered (see news release 28 October 2009). The Q1/Q2 2010 drill programme consisted of 4,400m in 37 holes and tested Calandria Sur (28 holes/3,212m); Calandria Norte (2 holes/299m), El Nido Este (2 holes/309m) and El Nido Norte (5 holes/580m). The Q3 2010 programme consisted of 14,004 m in 109 holes; Calandria Sur (56 holes/6,186m); Calandria Norte (43 holes/6,175m); Nido Norte (7 holes/1,054m); Nido Oeste (2 holes/421m); La Herradura (2 holes/168m).

Argentex commences 17,000-meter drill program at Pinguino, Santa Cruz, Argentina

VANCOUVER, Jan. 24 /CNW/ - Argentex Mining Corporation (TSX-V: ATX, OTCBB: AGXM) is pleased to announce that the company has commenced drilling at its Pinguino silver project in Santa Cruz, Patagonia, Argentina.

The proposed 17,000-meter drill program will initially target shallow, silver-rich mineralization discovered in late 2010 drilling. Multiple centers of this type of high-grade mineralization were discovered throughout the Pinguino property in veins including Tranquilo, Marta Norte, Tranquilo Sur and Luna. These discoveries remain wide open in all directions and have excellent potential for expansion. Previously published results in these areas include Hole P349-10, which returned an intersection of high-grade silver mineralization containing 6.0 meters of 2,428 grams per tonne (g/t) silver and 0.22 g/t gold, Hole P358-10 containing 4.6 meters of 313 g/t silver and 0.16 g/t gold, and Hole 308-10 containing 6.40 meters of 486.6 g/t silver and 1.91 g/t gold.

"We have a strong treasury and we are excited to begin this strategic phase of drilling at Pinguino, targeting the previously discovered high-grade silver intersections for expansion along strike and at depth," said Ken Hicks, President of Argentex. "We have never been in a better position to move the company forward and demonstrate the excellent geological potential at Pinguino."

Drilling will also target a potential new zone of mineralization believed to occur throughout the Pinguino district-scale mineralized vein system. This zone is represented at the transition point above the contact between oxide and primary mineralization. Management believes this zone represents an area of mineralized enrichment that has only recently been recognized. It holds potential for higher grade near-surface mineralization.

Additionally, drilling will target numerous areas with well-defined drill targets to expand the existing mineral resource at depth. Gradient IP surveys currently in progress will be used to further refine targets, expand known mineralized signatures to depth and develop new drill targets.

Surface Rights

Argentex's recent acquisition of the surface rights overlaying Pinguino solidifies the company's presence and commitment to the long-term vision for the project. Securing both the mineral and surface rights is a key combination in creating the stable environment that meets the needs of the company now and in the future.

About Pinguino

Argentex's Pinguino property is located in Argentina's Patagonia region, within the Deseado Massif of Santa Cruz province. Recent high-grade silver discoveries within the newly tested Tranquilo structure of the district-scale vein system at Pinguino show potential for the development of a significant silver resource.

The Deseado Massif is an active region of mining with four precious metal mines currently in production. Advanced and early-stage exploration projects are also widespread throughout the Deseado Massif with junior, mid-tier and senior exploration companies active in the area.

Quality Assurance

Samples selected for analysis are sent to Acme Analytical Laboratories' sample preparation lab in Mendoza, Argentina. From there sample pulps are sent to Santiago, Chile for fire assay gold analysis and to Vancouver, Canada for Group 1DX multi-element MS-ICP analysis. Samples with over-limit zinc, lead, silver and/or copper are reanalyzed using an ore-grade high detection limit 7AR analysis, also conducted in Vancouver. Acme Analytical Laboratories is an accredited ISO 9000:2001 full-service commercial laboratory with its head office in Vancouver. Referee analyses will be carried out by ALS Chemex (Argentina) in Mendoza, Argentina. Argentex, Acme and ALS Chemex all maintain comprehensive and independent Quality Control/Quality Assurance programs.

ABOUT ARGENTEX:

Argentex Mining Corporation is a Delaware corporation. It is a junior mining company in the exploration stage with significant holdings in the Patagonia region of Argentina. It holds an undivided 100% interest in the mineral rights to the Pinguino property. In total, the company owns 100% mineral rights to more than 35 properties with approximately 307,981 acres (124,636 hectares) of prospective land located in the Santa Cruz and Rio Negro provinces of Argentina. Shares of Argentex common stock trade under the symbol AGXM on the OTCBB and on the TSX Venture Exchange under the symbol ATX.

Exploration on the Pinguino property is being conducted under the supervision of Mr. Kenneth Hicks, P.Geo., Argentex's President and a Qualified Person as defined by Canada's National Instrument 43-101. Mr. Hicks has read and approved the contents of this release and as part of company management, he is not considered independent of the issuer.

Extorre Gold Mines Limited: Cerro Moro Infill Drilling for Pre-Feasibility Study Completed- Drilling Now Focussed Entirely on New Veins and Extensions

VANCOUVER, BRITISH COLUMBIA--(Marketwire - Jan. 24, 2011) - Extorre Gold Mines Limited (TSX:XG) (FRANKFURT:E1R) (OTCQX:EXGMF) ("Extorre" or the "Company") is pleased to report high gold-silver grades from the final assay batch of the infill drilling program at its 100% owned Cerro Moro Project in Santa Cruz Province, Argentina. The purpose of the infill drilling at the Gabriela and Loma Escondida vein zones was primarily to upgrade Inferred category resources to the Indicated category. Only Indicated resources will be included in the Cerro Moro Pre-Feasibility Study ("PFS"), which is due for completion in the second quarter of 2011.

Of the 46 drill holes completed, 24 returned significant results including the following exceptional intercepts:

Gabriela Vein

MD1066 intersected 4.80 metres ("m") at 12.4 grams per tonne ("g/t") gold + 1,603 g/t silver (39.1 g/t gold equivalent*)

including 0.79 m at 70.7 g/t gold + 8,935 g/t silver (219.6 g/t gold equivalent*)

Loma Escondida Vein

MD1073 intersected 2.63 m at 14.8 g/t gold + 1,208 g/t silver (35.0 g/t gold equivalent*)

including 0.30 m at 81.5 g/t gold + 6,851 g/t silver (195.7 g/t gold equivalent*)

MD1087 intersected 0.77 m at 105.3 g/t gold + 1,592 g/t silver (131.8 g/t gold equivalent*)

including 0.35 m at 224.1 g/t gold + 2,748 g/t silver (269.9 g/t gold equivalent*)

Eric Roth, Extorre´s President and CEO, stated "The infill drill program has been successful in confirming continuity of high grade gold-silver mineralization in both the Loma Escondida and Gabriela vein zones. These veins are very important as they will potentially provide high grade open pit ore to the Cerro Moro plant in the early production years. It is noteworthy that this batch of results includes the highest silver-gold grades obtained to date from the Gabriela vein.

"The completion of the infill drilling allows us to focus the four rigs on establishing the upside of the extensive Cerro Moro vein system. We expect to drill +5,000 metres per month through 2011, allowing us to test many targets that have had little or no drilling to date."

Significant results from Gabriela vein infill drilling (at a 1.0 g/t gold equivalent* cut-off grade):




















Significant results from Loma Escondida vein infill drilling (at a 1.0 g/t gold equivalent* cut-off grade):














Note: Drill hole MD1036 at Loma Escondida appears to have intersected significant mineralization but results are still pending.

The infill drill results from the Gabriela and Loma Escondida veins will form part of the database for an updated independent mineral resource estimate. The new mineral resource model will be delivered to Santiago-based NCL Ltda who will update the mining plan and ore delivery schedule for inclusion in the PFS.

The results from an additional 48 drill holes are expected to be released to the market within the next two weeks. These drill holes are part of the discovery drilling program and represent the final batch of samples from 2010 drilling. All drilling and field operations have resumed from a Christmas to New Year recess period. Acme Analytical Laboratories are expected to commence on-site sample preparation at Cerro Moro on February 1.

Marina Trasolini appointed Vice President - Corporate Development

Extorre is also pleased to announce the appointment of Ms. Marina Trasolini as Vice President - Corporate Development. Marina currently holds Bachelor of Science - Geology and Bachelor of Education - Secondary Science degrees from the University of British Columbia (UBC), and will shortly complete an MBA in Finance from the same institution. Before joining Extorre, Ms. Trasolini worked as the Senior Research Analyst for renowned newsletter writer Lawrence Roulston, editor of the Resource Opportunities Investment Newsletter. In that role she became well versed in corporate finance, equity financings, company valuations and M&A dealings in the mining sector. Prior to this, Ms. Trasolini worked for a junior exploration company as an exploration geologist.

Quality Control and Assurance

Drill widths presented above are drill intersection widths and may not represent the true widths of mineralization.

Gold assay results presented above are preliminary with no cutting of high grades. All diamond drill core samples are split on regular metre intervals or on geological contacts and represent sawn half HQ-size core. Reverse circulation drill samples are collected using a cyclone in one metre intervals. Samples were prepared at the Acme Analytical Laboratories ("AcmeLabs") preparation facility in Mendoza, Argentina and assayed by fire assay (50 gram charge) at the AcmeLabs laboratory in Chile, both ISO-9001:2000 certified laboratories.

Check assaying of all samples assaying greater than 1.0 g/t gold is completed by Acme Labs. Samples returning greater than 10 g/t gold and/or greater than 100 g/t silver are assayed using gravimetric analyses. Standard and blank samples are used throughout the sample sequence as checks for the diamond drilling reported in this release. Standard, blank and duplicate samples are used throughout the sample sequence as checks for the RC percussion drilling.

Assaying by the screen fire assay method has been implemented in conjunction with standard 50 gram fire assaying, for diamond drill cores that contain visible gold. The procedure for screen fire assaying involves crushing and sieving of a nominal 1,000 gram sample to a particle size of 100 microns. All material which does not pass through the 100 micron sieve is then assayed. Two fire assays are undertaken on the undersize material as a check on homogeneity. The total gold content is then calculated.

Matthew Williams, Extorre's Exploration Manager and a "qualified person" within the definition of that term in National Instrument 43-101, Standards of Disclosure for Mineral Projects, has supervised the preparation of the technical information contained in this news release.

Indicated Category: 357,000 oz. gold + 15.3 million oz. silver (612,000 oz. gold equivalent*), plus
Inferred Category: 190,000 oz. gold + 12.0 million oz. silver (390,000 oz. gold equivalent*)

The 612,000 ounce gold equivalent* indicated resource, has an average grade of 32.3 g/t gold equivalent*, a grade considered exceptional by industry standards. The silver contribution is high, accounting for over 40% of the metal value. Additional inferred resources of 390,000 ounces gold equivalent* are also reported from Cerro Moro.

Extorre released the results of a PEA of the Cerro Moro Project on October 19, 2010. The PEA highlighted the robust economics of a future Cerro Moro mine expected to produce an average of 133,500 gold equivalent* ounces annually during the first 5 years of operations. The cash cost per ounce (gold equivalent*) is estimated to be US$ 201 per ounce. Project CAPEX has been estimated at US$ 131 million (of which 21% is a VAT that is refundable after production commences). The project payback period is 1.8 years. The project economics were calculated using gold and silver prices of US$ 950/ounce and US$ 16/ounce, respectively.

Extorre submitted an Environmental Impact Assessment for the Cerro Moro mine development to Santa Cruz Authorities on September 16, 2010. Mining permits and approvals for the Cerro Moro mine are expected to be received by the end of Q1-2011.

U3O8 Corp. Outlines 2011 Exploration Program Aimed at Rapidly Expanding Its NI 43-101 Resource Portfolio in South America

TORONTO, ONTARIO--(Marketwire - Jan. 24, 2011) - U3O8 Corp. (TSX VENTURE:UWE), a Canadian-based company, focused on exploration and resource expansion of uranium and associated commodities in South America, today announced its planned exploration program, which aims to substantially increase its National Instrument 43-101 ("NI 43-101") resource portfolio in Colombia, Guyana and Argentina in 2011.

The primary objectives are:

* Berlin Project, Colombia: to define a potential NI 43-101 resource of an initial 20 to 25 million pounds ("mlb") uranium in part of the area on which a historic resource was estimated1;

* Kurupung Project, Guyana: to expand the current NI 43-101 resource to 20 to 25mlb2 of uranium while continuing to show further size potential of the Kurupung uranium system; and

* Laguna Salada Project, Argentina: to report a NI 43-101 resource estimate on Laguna Salada while exploring the next target with the aim of increasing the overall resource to 20 to 24mlb3 uranium on these two projects in southern Argentina.

Berlin Project1

A 10,000 metre ("m") exploration drilling program is underway in the southern part of the mineralized trend at Berlin – in the area on which a historic resource was estimated. A second drill rig is scheduled to arrive on-site in February. U3O8 Corp's trenching has demonstrated consistent mineralization over 3km along trend and drilling has intersected similar uranium grades to historic data, but over greater widths than those recorded in historic reports. In addition, potential co-products including phosphate, vanadium, yttrium, rhenium, molybdenum and silver have been identified (December 8, 2010 press release).

Preliminary metallurgical test results are expected in Q1 2011. Infill drilling is planned to start in Q2 as the Berlin Project is advanced towards a potential NI 43-101 uranium resource estimate with an initial objective of 20 to 25mlb by year-end. In addition, trenching continues in the northern part of the property to confirm historic records that show that the entire 10.5km mineralized trend is prospective, which could substantially expand the size potential of the project.

Kurupung Project2

An infill drill program of approximately 11,000m is planned to begin in March, on the first of three mineralized areas: the Aricheng West corridor, Aricheng C, and on the Accori North C structure – towards expanding the current NI 43-101 resource on the Kurupung Project (January 20, 2011 press release).

Concurrent with infill drilling, scout drilling will continue with the aim of showing that the Kurupung could be of comparable size to peer deposits that typically contain 60 to 130mlb of uranium4.

Laguna Salada Project3

Initial metallurgical test results and a NI 43-101 resource on Laguna Salada are expected in Q1 2011. U3O8 Corp. has commenced exploration of another surficial uranium target with similar size potential and grade to Laguna Salada. As with Laguna Salada, exploration of the second target is planned through mechanized trenching due to the soft and unconsolidated nature of the uranium-vanadium - bearing gravels. The goal is to have a cumulative resource estimate of 20 to 24mlb completed on the two projects in southern Argentina by the end of 2011.

"U3O8 Corp. has established a clear path to efficiently and rapidly increase its uranium resources through organic growth in the next 12 months," said Dr. Richard Spencer, U3O8 Corp's President and CEO. "In addition, we are finding potentially valuable co-products such as phosphate, vanadium, rhenium and the heavy rare earth, yttrium."

Dr. Richard Spencer (P.Geo.), CEO and President of U3O8 Corp., a Qualified Person within the definition of that term in NI 43-101 of the Canadian Securities Administrators, has overall responsibility for all aspects of the exploration program. Dr. Spencer has supervised the preparation of, and verified, the technical information in this release.

About U3O8 Corp.

U3O8 Corp. is a Toronto-based exploration company, focused on exploration and resource expansion of uranium and associated commodities in South America – a promising new frontier for exploration and development in the uranium industry. U3O8 Corp. has one of the most advanced portfolios of uranium projects in the region comprising NI 43-101 compliant resources in Guyana to significant historic resources in Colombia and near-resource and discovery potential in Argentina.

1. The Berlin Project has a historic resource of 12.9 million tonnes at an average grade of 0.13% U3O8 (38mlb U3O8) and is reported in Castano, R. (1981), Calcul provisoire des reserves geologiques de Berlin, sur la base des resultants des sondages, unpublished Minatome report, 15p. There has been insufficient exploration to verify the historic estimate and it should not be relied upon as a NI 43-101 compliant resource.

2. Scout drilling to date suggests that the Kurupung may contain a conceptual target of 13-18 million tonnes at a grade of 0.08% to 0.10% U3O8 (estimated 30 to 35mlb U3O8) including the initial NI 43-101 resource. The initial NI 43-101 resource estimate of 5.8mlb Indicated at an average grade of 0.10% (2.0 lbs/st) U3O8 and 1.3mlb Inferred at an average grade of 0.09% (1.9 lbs/st) U3O8 was reported on the Aricheng North and Aricheng South structures. Refer to the technical report dated January 14, 2009 titled "A Technical Review of the Aricheng North and Aricheng South Uranium Deposits in Western Guyana for U3O8 Corp. and Prometheus Resources (Guyana) Inc.", available on U3O8 Corp's web site at www.u3o8corp.com and on SEDAR at www.sedar.com.

3. Based on trench results reported to date on the Laguna Salada Project (press release dated October 27, 2010), two projects of similar size and grade have the potential to contain a cumulative target of 9 to 11 million tonnes at a grade of 100ppm to 150ppm U3O8 (estimated 20 to 24mlb U3O8).

4. Geologically similar albitite-hosted uranium deposits worldwide (e.g. Coles Hill (USA), the Valhalla (Australia) and Michelin (Canada)) typically host resources in the 60 to 130mlb range with typical grades of 0.06% to 0.10% U3O8. These deposits have not been independently verified by U3O8 Corp. and information regarding these deposits is drawn from publicly available information. Comparisons of U3O8 Corp's uranium resource and exploration targets with other uranium deposits are conceptual in nature. There is no certainty that further exploration of U3O8 Corp's resource or targets will result in a similar mineral resource.

Marifil Acquires K-4 Potash Project and Adds More Property to K-3

Geologic Studies Suggest Good Probability of Potash, Uranium, Lead, Zinc and Asphaltite

LAS VEGAS, NEVADA--(Marketwire - Jan. 23, 2011) - MARIFIL MINES LTD. (TSX VENTURE:MFM) ("Marifil" or "the Company") announces that an ongoing exploration program for potash in the Neuquen Basin in Argentina resulted in the identification and acquisition of a second large area highly favourable for potash in the northern portion of the basin in Mendoza Province (see news release dated December 13, 2010).

The Company has acquired by staking four cateos (claims) totalling 30,000 hectares (300 square kilometres) that it believes are highly prospective for potash. The claims, the K-4 Project, may also be prospective for uranium, biogenic sulfur (similar to the Company's Codihue sulfur project), Mississippi Valley type lead and zinc (similar to the Company's Picun Lefu lead zinc project), and for asphaltites (hard bitumens which can, through heating, be a source of petroleum).

Geologic mapping and basin analysis identified this large area as having good potential for salt horizons at depths ranging from 500 m to 2,000 m. The evaporate salt horizons are believed to range from 50 m to 350 m in thickness. Analysis of electric and gamma ray logs from abandoned oil wells is ongoing. Potash (a mineral salt with the chemical formula KCl) typically occurs near the top of thick evaporate salt horizons.

Research also identified additional area adjacent to the K-3 property. The Company staked a 10,000 hectare cateo to cover this prospective zone.

The southern part of the Company's K-3 project lies about 50 kilometers northwest of Vale's giant Potasio Rio Colorado potash mine which has a resource of 2 billion tons of potassium chloride. The K-4 project is located about ten kilometres north of the K-3 project (see attached map below).

"Our geologists have had an ongoing program in this region," stated John Hite, President of Marifil Mines. "Their work reveals that this part of the Neuquen Basin has high potential for potash, lead, zinc, uranium, and asphaltite. We are very pleased to have secured these highly prospective claims, one of four of the Company's potash properties.

The K-1 property has been sold to Allana Resources; K-2, an 80,000 ha project, is subject to a Letter of Intent with Saccharum Energy Corp.; and K-3 is subject to a Right of First Offer to Saccharum. The K-4 project is not subject to the Right of First Offer clause given to Saccharum Energy. However, in keeping with our business plan, the Company intends to farm out or joint venture this property. "

For further information regarding Marifil Mines Ltd., please refer to the Company's filings available on SEDAR (Http://www.sedar.com) or at Marifil's Website (Http://www.marifilmines.com.)

This press release has been reviewed and approved by John Hite, President of Marifil Mines Ltd. and by Richard Walters, Vice President under whose directions the exploration program is being carried out. Mr. Hite and Mr. Walters are Qualified Persons as defined by National Instrument 43-101.

TORONTO, ONTARIO--(Marketwire - Jan. 20, 2011) - Malbex Resources Inc. (TSX VENTURE:MBG) announced results today from preliminary metallurgical testing of samples from the Company's Del Carmen Norte gold-silver (Au-Ag) project in San Juan province, Argentina. Overall, test results indicate good potential for heap leach cyanidation treatment and for whole ore milling/cyanidation treatment of the materials represented by the five composite samples tested. Most encouraging are results from material crushed to 6.3 millimetres (mm) to obtain preliminary information on heap leach amenability. Four of five 6.3 mm samples had Au recoveries ranging from 78.3 to 83.1% while the fifth sample showed 61.4% recovery, with an overall average of 76.5%. Silver recoveries ranged from 15% to 65% for those samples with detectable silver (four of five) and were generally higher for milled compared to crushed material. Cyanide consumption for all samples was low with an average for all tests of 0.16 kg/t.

"We're very encouraged by the results of initial metallurgical testing, which confirm our earlier observations that the Au-Ag mineralisation at Del Carmen Norte is strongly oxidized and amenable to extraction of gold by low-cost heap leach technology," said Tim Warman, President & CEO. "Our next goal is to complete sufficient drilling to demonstrate continuity of mineralisation in the Rojo Grande area, and support an initial resource calculation. We have also commenced the first drill test of a large resistivity target at Cerro Amarillo, identified by last season's geophysical surveying."

The metallurgical samples are roughly 15 kilogram (kg) composites of previously sampled half core (i.e., quarter core) that are representative of the average grades of significant intervals of mineralisation at the Rojo Grande (samples RG1, RG2 and RG3) and Naciente Quebrada Pedregosa (samples NQP1 and NQP2) targets at Del Carmen Norte. Average measured head grades for the composites range from 0.67 to 2.21 grams per tonne (g/t) Au compared to a range of 0.57 to 2.64 g/t Au in the selected intervals. Details of each composite are available on the Malbex website by clicking the following link: metallurgical samples.

Compositing and metallurgical testing was carried out by McClelland Laboratories Inc. of Sparks, Nevada. Each composite was crushed to determine gold and silver recoveries at four feed sizes based on 80% passing (P80) 12.5 mm, 6.3 mm, 212 micron (µm) and 150 µm. The testing provides information on sensitivity of cyanidation to feed size, recovery rates, reagent requirements, and variability of potential ore at Del Carmen Norte. The crushed feeds (12.5 mm and 6.3 mm) provide preliminary information on the amenability to heap leaching. The milled feeds (212 µm and 150 µm) test the amenability of each composite to milling and agitation cyanidation treatments such as carbon-in-pulp (CIP).

Direct leaching (bottle roll) tests indicate the mineralisation intersected in previous drilling represented by five composite samples from the Rojo Grande and Naciente Quebrada Pedregosa targets at the Del Carmen Norte prospect are amenable to cyanidation processing of either crushed or milled material. Gold recoveries for each milled fraction (212 µm and 150 µm) ranged from 82% to 89% after 72 hours of leaching with comparable results for both size fractions. Gold recoveries after 96 hours of agitation were lower for crushed material compared to milled fractions and were clearly improved by the reduction from 12.5 mm to 6.3 mm. Four of five 6.3 mm samples had Au recoveries ranging from 78.3 to 83.1% while the fifth sample showed 61.4% recovery.

The complete metallurgical report can be viewed by clicking on the following link: metallurgical report. Further information about Del Carmen Norte, including maps, sections and a complete assay table may also be accessed at www.malbex.ca/Projects/Del_Carmen.

About Del Carmen Norte and the Rojo Grande and Naciente Quebrada Pedregosa targets

The Del Carmen Norte prospect consists of the roughly 3 by 3 kilometre (km) high-sulphidation hydrothermal system consisting of silicification, quartz-alunite, advanced argillic (kaolinite) and argillic (illite) alteration. Rojo Grande consists of prominent reddish weathering silicified outcrops on the northern flank of the massif of high sulphidation hydrothermal alteration. Clay (argillic and advanced argillic) and quartz-alunite alteration and silicification typically lighten the normally darker, intermediate volcanic rocks affected by the hydrothermal alteration. Diamond drilling has intersected near-surface Au-Ag mineralization at Rojo Grande over an area about 200 m by 150 m including intervals of:

* DDHC-10-017: 41 m grading 1.18 g/t Au and 31.2 g/t Ag (1.70 g/t Au-EQ)
* DDHC-10-018: 15 m grading 1.07 g/t Au and 27.3 g/t Ag (1.53 g/t Au-EQ)
* DDHC-10-020: 124.5 m grading 0.57 g/t gold (Au) and 8.8 g/t silver (Ag) (0.72 g/t Au-EQ)
* DDHC-10-031: 38 m grading 0.88 g/t Au and 12.2 g/t Ag (1.09 g/t Au-EQ)
* DDHC-10-032: 142.15 m grading 0.88 g/t Au and 13.7 g/t Ag (1.11 g/t Au-EQ), including 40.15 m grading 1.45 g/t Au and 19.6 g/t Ag (1.78 g/t Au-EQ)
* DDHC-10-034: 73 m grading 0.74 g/t Au and 17.4 g/t Ag (1.03 g/t Au-EQ)

Although fresh sulphides, mainly pyrite, occur in flanking, mainly barren clay-altered rocks, intervals of silicification and quartz-alunite alteration which host virtually all of the Au-Ag mineralisation lack visible sulphide minerals. Mineralization at Rojo Grande is hosted by vuggy silica and massive silicification with fine-grained hematite, goethite and jarosite veinlets and red-brown staining. The silicified outcrops at Rojo Grande are interpreted to be part of a sub-horizontal sheet formed by preferential silicification and quartz-alunite alteration of volcanic breccias within the altered volcanic sequence. Northeast-striking zones of hydrothermal breccias cemented by chalcedony and very fine-grained quartz locally cut pre-existing silicification. Many of the above intersections are bounded by changes in style of alteration, faults or both as altered rocks are cut by northeast-, north-northwest- and east-striking fault zones. While some faults clearly post-date the hydrothermal events (they displace and truncate silicification for example), hydrothermal feeder structures that controlled alteration and mineralization are inferred to preferentially coincide with one or more fault directions.

The Naciente Quebrada Pedregosa prospect lies within predominantly quartz-alunite alteration about 1,200 m south of the Rojo Grande target where mapping identified northeast-striking silicified structures with up to 165 g/t Au in surface samples (see PR of February 17, 2010). DDHC-10-023 contained the best results in the four-hole fan drilled to test this difficult to access target with multiple intercepts of mineralization apparently hosted by altered structures cutting dacitic volcanic rocks within the primarily andesitic sequence that includes:

* DDHC-10-023: 49 m grading 1.11 g/t Au, 21 m grading 1.69 g/t Au and 16 m grading 2.64 g/t Au and 6.08 g/t Ag

The metallurgical samples at Naciente Quebrada Pedregosa were composited from the longest zone of mineralization (NQP1) and the lowermost, slightly less silver-deficient mineralization (NQP2) in hole DDHC-10-023. The metallurgical samples at Rojo Grande were composited from the two longest intervals of Au-Ag mineralisation in holes DDHC-10-020 (RG1: entire 5.5-130m interval) and DDHC-10-032 (RG2: near-surface 34 m interval (23-57m); RG3: lowermost 40 m (124-164m)).

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 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 vertical).

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 10,000 m drill campaign will focus on defining the extent of Au-Ag mineralization at Rojo Grande, testing the large CSAMT resistivity anomalies, and follow up on previous encouraging results from Naciente Quebrada Pedregosa.

Technical Information

Diamond drill hole samples consist of HQ-3 (6.11 cm diameter) 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 Au) 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.

Minera Andes Announces Increased Silver and Gold Production for the Fourth Quarter and for the Year 2010 at the San Jose Mine

TORONTO, ONTARIO--(Marketwire - Jan. 19, 2011) - Minera Andes Inc. (the "Corporation" or "Minera Andes") (TSX:MAI)(OTCBB:MNEAF) announces the San José mine production results for the fourth quarter of 2010 and the year ended December 31, 2010. During the fourth quarter, the San José mine produced 1,871,440 ounces of silver and 26,141 ounces of gold, of which 49% is attributable to Minera Andes. For the full year of 2010 silver production was 5,323,842 ounces and gold production was 84,303 ounces.










Fourth quarter 2010 silver production was 33% higher and gold production was 19% higher compared to the third quarter of 2010. The increase in silver and gold production was the result of increased mill throughput, increased metallurgical recoveries for silver and gold, and higher grades for silver compared to the third quarter. The mill is currently operating routinely at full capacity. The increase in mill throughput was due to the development of additional production areas in the mine, and the improved silver grade was due to production from higher grade silver areas and because of incremental silver production from the Merrill Crowe circuit in the mill. Fourth quarter 2010 silver production increased 81% and gold increased 31% compared to the fourth quarter of 2009. Production in the fourth quarter of 2009 was reduced because of 15 days of labour disruptions.

Fourth quarter production cost information will be provided jointly with the financial results for the fourth quarter which are due to be filed at the end of March 2011.

Sales of silver and gold were 57% and 35% higher, respectively, in fourth quarter of 2010 compared to the third quarter as a result of increased ore production and a decrease in products inventory. Compared to the same quarter last year, sales of silver and gold in the fourth quarter of 2010 were 94% and 40% higher, respectively. This was mainly due to increases in mill throughput, metallurgical recoveries and head grades.

This news release is submitted by James K. Duff, Chief Operating Officer of Minera Andes Inc.

Argentex provides update on silver-gold exploration activities in Santa Cruz, Argentina

VANCOUVER, Jan. 19 /CNW/ - Argentex Mining Corporation (TSX-V: ATX, OTCBB: AGXM) is pleased to provide an update of its exploration activities from its three most advanced mineral properties in the prospective Deseado Massif region of Santa Cruz province, Patagonia, Argentina. The Pinguino, Cerro Contreras and Condor properties are the current focus of advanced exploration activities.

Pinguino Silver Project

In preparation for extensive new drilling scheduled to commence shortly, Argentex has completed a program of advanced exploration and drill target definition including trenching and geophysics. Approximately 275 line-kilometers of ground magnetometer surveys have been completed as well as 1,200 meters of trenching and channel sampling in key areas of precious metal mineralization.

Approximately 17,000 meters of drilling is planned in 2011 for the Pinguino property. Argentex plans to begin drill-testing the extents of previously identified high-grade silver targets. These areas 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 50 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 36,000 meters of drilling completed at Pinguino to date.

"We are focusing our exploration activities on defining and expanding previously discovered silver and gold mineralization at Pinguino," said Ken Hicks, President of Argentex. "We are fortunate to have a number of high-quality projects in Santa Cruz with excellent potential for discovery. With our strong treasury and a comprehensive exploration program in progress, we look forward to an exciting year of discovery in 2011."

The Pinguino project is unique within the Deseado Massif region of Santa Cruz province with two different and geographically distinct types of mineralization, one precious metal and the other sulphide-rich polymetallic. The company continues to evaluate the geological model of sulphide-enriched potentially mineralized intrusives at depth, forming the source for the polymetallic veins exposed on surface. In December 2010, Argentex initiated a deep gradient IP geophysical test in Pinguino's core area of sulphide-rich veins.

Cerro Contreras Gold Property

Cerro Contreras is an advancing exploration-stage epithermal gold project in the northern part of the Deseado Massif. Previous sampling has identified key areas with anomalous gold mineralization. The company recently completed detailed mapping in two areas: Main Vein (2.5 km by 2 km) and NW Dome (1.2 km by 0.5 km). A comprehensive program of geochemical sampling, including soils (544), screened samples (636) and rock channels (126), has also been recently completed. In addition, approximately 60 kilometers of gradient IP geophysics was carried out on the Main Vein target with detailed ground magnetometer surveys totaling 500 line kilometers completed on both targets. Analytical data is being compiled and integrated with geophysics.

Condor Gold Property

Follow-up exploration at Condor is focused on an updated geological model based on evidence derived from previous work. This evidence points toward a model of low-grade, large-tonnage gold mineralization composed of chalcedony and sulphide-rich hydrothermal breccias within rhyolitic domes. New work included detailed mapping covering approximately 16 square kilometers with 35 rock chip samples collected. In addition, approximately 1,600 soil and lag samples were collected for geochemical analysis. Detailed mapping revealed multiple previously unrecognized breccias zones. Several of these zones contain anomalies over 0.1 g/t gold, two returned over 0.5 g/t gold and one returned 14 g/t gold. Work is continuing.

About the Deseado Massif

The Deseado Massif is an active region of mining with four precious metal mines currently in production. Advanced and early-stage exploration projects are also widespread throughout the Deseado Massif with junior, mid-tier and senior exploration companies active in the area.

Quality Assurance

Samples selected for analysis are sent to Acme Analytical Laboratories' sample preparation lab in Mendoza, Argentina. From there sample pulps are sent to Santiago, Chile for fire assay gold analysis and to Vancouver, Canada for Group 1DX multi-element MS-ICP analysis. Samples with over-limit zinc, lead, silver and/or copper are reanalyzed using an ore-grade high detection limit 7AR analysis, also conducted in Vancouver. Acme Analytical Laboratories is an accredited ISO 9000:2001 full-service commercial laboratory with its head office in Vancouver. Referee analyses will be carried out by ALS Chemex (Argentina) in Mendoza, Argentina. Argentex, Acme and ALS Chemex all maintain comprehensive and independent Quality Control/Quality Assurance programs.
