Marifil Signs Letter of Intent for the K-2 Potash Property

LAS VEGAS, NEVADA--(Marketwire - Dec. 21, 2010) - MARIFIL MINES LTD. (TSX VENTURE:MFM) ("Marifil" or "the Company") announces that it has signed a Letter of Intent of behalf of itself and Marifil's subsidiary Oxbow Holdings Corp. with Saccharum Energy Corp. (TSX VENTURE:SHM) of Calgary, AB, for the K-2 Potash property in Neuquen Province, Argentina.

Saccharum has agreed to pay $10,000 for an exclusive 60 day due diligence period to check title and further agrees to purchase all of the shares of Oxbow for a price of one cent per share. Marifil then agrees to restructure its underlying agreement with Oxbow whereby Saccharum can earn a 75% interest in the K-2 property.

Saccharum will pay Marifil US$500,000 in cash plus 2,000,000 Saccharum common shares over three years. The first year's payment to Marifil will be US$150,000 in cash and 1,000,000 shares upon Saccharum's completion of a financing.

Saccharum further agrees to spend US$4,500,000 in work over the next four years as follows: US$1,000,000 per year for the first three years and US$1,500,000 during the fourth year.

Saccharum will also pay Marifil performance bonuses of 1,500,000 shares upon completion of a positive NI 43-101 compliant resource and a further 1,500,000 shares following completion of a Feasibility Study. If Saccharum's share structure exceeds 75,000,000 shares during this agreement the shares payable to Marifil shall be adjusted upward proportionately. Upon completion of Saccharm's earn-in all furher expenditures shall be shared 75:25. If a partner fails to pay its share that partner shall be diluted to a 1.5% Net Smelter Royalty. Saccharum shall have the right to purchase Marifil's royalty for US$15,000,000.

Saccharum is also required to restructure its Board by effecting the appointment of Messrs. Todd Montgomery and Brent Walter as directors.

Mr. John Hite remarks, "We believe this is an important milestone for the Company. Mr. Montgomery was formerly President and CEO of Anglo Potash and Mr. Walter was a director of Anglo Potash. Both men guided Anglo through the discovery and development phase, brought in BHP Billiton to develop the potash deposit, and eventually sold Anglo's remaining 25% of the deposit for US$284,000,000. Bringing these gentlemen onto Saccharum's board will lend credibility to the development of this project."

Marifil also agreed to give Saccharum Right of First Offer for the Company's K-3 potash project located in neighboring Mendoza Province.

This agreement is subject to approval by the Boards of Directors of Saccharum, Marifil, and Oxbow and the TSX. A small finder's fee is payable to a third party.

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.

Renaissance Gold Inc. Announces Drill Results From the Meridiano Gold Project Santa Cruz Province Argentina

VANCOUVER, BRITISH COLUMBIA--(Marketwire - Dec. 20, 2010) - Composite results from drilling on the Meridiano Project, that was conducted by Renaissance Gold, Inc. (RenGold) (TSX VENTURE:REN), and fully funded by Agnico-Eagle (USA) Limited (a wholly-owned subsidiary of Agnico-Eagle Mines Limited) were completed in late 2010. Drill results include many intercepts of low grade gold mineralization including 39.4 feet of 0.015 opt gold (12 metres of 0.500 g/t gold) and 9.8 feet of 0.040 opt gold (3 metres of 1.376 g/t gold). Ten of the 32 holes drilled have reportable grades (at least ten feet of 0.010 opt).















These intercepts are believed to be at an angle to the steeply dipping structural zones. Most drill holes were at 60 degrees inclination and an estimate of true thickness would be roughly half than the reported intercept thickness. The zones are not entirely planar however and dips do vary, so until 3D modeling is complete the true thicknesses are unknown.

Drilling was primarily focused on recessive, low sulfidation, epithermal structural zones defined by sulfidic breccias in Jurassic age felsic volcanics. This area was discovered using proprietary TM imagery that highlighted a 200m long argillic alteration zone with breccias. Initial rock chip sampling, in this recessive zone, yielded consistent anomalous gold values. Detailed mapping exposed several kilometers strike length of crossing- cutting structural zones and follow-up surface samples of over 8 g/t Au were obtained. Prior work on the property consisted of sampling on siliceous rocks with positive relief and no previous drilling had been done.

These data show that gold mineralization has good horizontal continuity within the structural corridors. Drilling to date has only been shallow however, with the deepest penetration to 453 feet (138 metres) due to the inclination of the drill holes. Most drill holes are much less than 300' (92 metres). Results are being evaluated to consider further exploration. Drill samples were collected following standard industry practice and assayed by Alex Stewart Laboratories of Mendoza, Argentina. Gold results were determined using standard fire assay techniques on a 50 gram sample. QA/QC included the insertion of standards and blanks into the sample stream, and a check assaying program based on checks being given fictitious sample numbers and sent to the same laboratory.

Richard L. Bedell, Certified Professional Geologist, is the Company's designated Qualified Person for this news release.

Minera Andes Announces Updated Preliminaryassessment For Its Los Azules Copper Deposit


TORONTO, ONTARIO - December 16, 2010 - Minera Andes Inc. (TSX: MAI and US OTC: MNEAF) - is pleased to announce the results of an updated preliminary assessment ("PA") on its 100% owned Los Azules Copper Project (the "Project") located in the San Juan Province of western central Argentina. It is based on the updated resource estimate announced in June 2010 and higher base case metal price assumptions.

* Using a Copper price of $3.00/ lb
* Base case pre-tax Net Present Value ("NPV") is $2.8 billion and the Internal Rate of Return ("IRR") is 21.4%, at a discount rate of 8%
* Life of mine Cash Operating Costs of $0.96/lb of copper net of gold and silver by-product credits.
* Initial Capital $2.9 billion
* Capital Payback in 3 years.
* Mine life of 25 years.

Rob McEwen, Chairman and CEO of Minera Andes, said:

"We are advancing the engineering studies on Los Azules to systematically de-risk the project. The field season is just getting underway, and we are currently mobilizing the first two of five drill rigs to the project. In addition to continuing the infill and step out drilling, we will start to test some of the newly identified deeper geophysical targets this season."

The Los Azules Copper Project is an advanced-stage porphyry copper exploration project located in the cordilleran region of San Juan Province, Argentina near the border with Chile. The deposit is a typical porphyry copper system in that the upper part of the system consists of a barren leached cap, which is underlain by a high-grade secondary enrichment blanket, and the primary mineralization below the secondary enrichment zone extends to at least 650 meters, which is the depth of the deepest holes drilled to date. The deposit is approximately one kilometer wide by four kilometers long, and it is open in several directions.

Highlights of the updated Preliminary Assessment are shown below. Details may be found in an updated technical report which will be posted on SEDAR following the issuance of this news release.















Compared to the previous Preliminary Assessment released in March 2009, the NPV discounted at 8% has increased from $496 million to $2.9 billion and the IRR has increased from 10.8% to 21.4%. In addition, the payback of pre-production capital has decreased from 6.4 years to 3.1 years from the start of production.

The main driver of the improved project economics is that the base case copper price has been increased from $1.90/pound to $3.00/pound. Specifically, the higher copper price added approximately $3.2 billion to the NPV, and the increased resources added approximately $2.1 billion.

The benefits of the higher copper price and increased resources were significantly offset by increases in the estimated operating costs ($695 million), capital costs ($100 million) and export retention taxes and royalties ($3.4 billion).

The updated Preliminary Assessment also incorporates updated property status and ownership information, revised locations for the project facilities, and an updated geological interpretation.

Project Economics

The Preliminary Assessment contains a cash flow valuation model based upon the geological and engineering work completed to date and technical and cost inputs developed by Samuel Engineering, Inc., Ausenco Vector and MTB Project Management Professionals, Inc. The base case was developed using long term forecast metal prices of $3.00/lb for copper, $980/oz for gold, and $15.60/oz for silver.

The following chart shows the sensitivity of the base case's NPV and IRR to changes in the copper price: (8% real discount rate).















The following chart shows the sensitivity to metal prices, operating costs, and capital cost. The graph shows that the project NPV is much more sensitive to metal prices than to capital or operating costs.

The Corporation had $10 million USD in cash as at September 30, 2010 with no bank debt. Rob McEwen, Chairman and CEO, owns 33% of the company.

This news release has been submitted by Jim Duff, Chief Operating Officer of the Corporation. For further information, please contact Jim Duff or visit our Website: www.minandes.com.


Scientific and Technical Information:

The information presented in this press release has been reviewed and approved by the Qualified Persons responsible for the Technical Report that presents the results of the Updated Preliminary Assessment. They are: Kathleen Altman, Ph.D., PE,, Robert Sim, P.Geo,. Bruce Davis, PhD, FAusIMM, Richard Jemielita, Ph.D., MIMMM, William Rose, PE, and Scott Elfen, PE. All are independent Qualified Persons as defined by National Instrument 43-101 "Standards of Disclosure for Mineral Projects" ("NI 43-101"). Robert Sim, Bruce Davis, and William Rose are responsible for the mineral resource estimate. Bruce Davis is responsible for the quality control for the assaying of the Los Azules drill core. All samples were collected in accordance with industry standards. Splits from the drill core samples were submitted to the ACME sample preparation laboratory in Mendoza, Argentina and then transferred to ACME's laboratory in Santiago, Chile for fire assay and ICP analysis. Accuracy of results is tested through the systematic inclusion of standards, blanks and check assays. William Rose is responsible for developing the mine production schedule and participating in the resource estimate. Scott Elfen of Ausenco Vector is responsible for information about Environmental Liabilities, Environmental Permitting and for the Geotechnical designs used for the Study. Richard Jemielita is responsible for information about the Geological Setting, Deposit Types, Mineralization, Exploration, and Drilling. Kathleen Altman, Samuel Engineering, Inc., is the principal author of the Report with specific responsibility for Mineral Processing and Metallurgical Testing, the capital and operating cost estimates and the economic evaluation.

Mineral resources are generated using ordinary kriging with a nominal block size of 20x20x15m. Block grade estimates are derived from drill hole sample results and the interpretation of a geologic model which relates to the spatial distribution of copper, gold, silver and molybdenum in the deposit. There are a total of 114 drill holes in the Los Azules database with a cumulative length of 30,997 meters and a total of 15,260 samples analyzed for a suite of elements including total copper, gold, silver and molybdenum. A total of 58 of the drill holes have some portion of the sample intervals tested for sequential copper analysis. This information contributed to the development of the mineral zone domains. The portion of the new mineral resource that has been defined as "indicated" is based on a drilling configuration that exhibits the degree of continuity required for higher level mineral resources. Inferred mineral resources are limited to blocks within a maximum distance of 200 meters from a drill hole. As required by NI 43-101, the possible future economic viability of the mineral resource has been exhibited by restriction within a pit shell derived about the copper content in indicated and inferred class blocks at a copper price of $2.50/lb, total operating costs of $5.25/tonne and an average pit slope of 34 degrees. Mineral resources are presented at a cut-off grade of 0.35%Cu, which is the same base cut-off grade used in the 2008 mineral resource estimate. These are mineral resources, not mineral reserves.


For further information in respect of the Los Azules project please refer to the technical report entitled "Canadian National Instrument 43-101 Technical Report Updated Preliminary Assessment, Los Azules Project, San Juan Province, Argentina" dated December 1, 2010, the "Los Azules Report." This report will be made available on SEDAR (www.sedar.com) concurrent with the filing of this news release. Inferred mineral resources are considered too speculative geologically to have the economic considerations applied to them that would enable them to be categorized as mineral reserves. There is no certainty that the project as described in the Los Azules Report will be realized.

Cautionary Note to U.S. Investors:

All resource estimates reported by the Corporation were calculated in accordance with NI 43-101 and the Canadian Institute of Mining and Metallurgy Classification system. These standards differ significantly from the requirements of the U.S. Securities and Exchange Commission. Mineral resources which are not mineral reserves do not have demonstrated economic viability.

Mirasol's First Drill Results Confirm the Virginia Silver Vein Zone, Argentina

VANCOUVER, Dec. 16 /CNW/ - Mirasol Resources Ltd. (TSX-V: MRZ, Frankfurt: M8R) is pleased to announce assay results for the first seven holes of the 28 hole, Phase 1 diamond drilling program at its 100% held Virginia Silver Project located in Santa Cruz Province, Argentina.

Phase 1 drilling targeted the 2.2 kilometre long Julia Vein, where 58 channel samples identified significant widths of silver mineralized vein and vein breccia. Best intersections from the first seven holes (Table 1) are from holes VG-006 with a true width of 22.7 metres grading 474 g/t (grams/tonne) silver, including 5.7 metres of 1,403 g/t silver; and hole VG-007 with 14.6 metres of 483 g/t silver, including 6.5 metres at 937 g/t silver.

Phase 1 comprised 28 core holes drilled during November and December, 2010, and totaled 1,615.6 metres (Figure 1). Results for the initial seven holes confirm that the high-grade surface silver mineralization, as defined by channel sampling, on the Julia Vein continues in the sub-surface and that at Julia North vein mineralization is surrounded by haloes of lower grade silver mineralization over significant widths in the wall rock.

All seven diamond drill holes reported here contained significant silver intercepts calculated using a 50 g/t silver cut off. All holes include intervals of higher grade mineralization with three of the seven holes containing intercepts of greater than 1,000 g/t silver.

Mirasol's management is pleased that initial Virginia drill results have confirmed the consistently high-grade silver results returned from surface sampling and looks forward to releasing the remaining 21 holes as results become available.
























Notes: All analyses done by ALS Laboratory Group, Mendoza, Argentina.

1. True widths have been estimated using cross sections of the mineralized intercepts with the geology of the drill hole and surface information.
2. Silver grades have not been capped and are thus "uncut".
3. Intercepts are calculated at a 50 g/t silver cutoff with no value given to gold or lead. Included intercepts are selected so as to show higher grade intervals.
4. Core recovery is the length weighted average of the intercept quoted.

Technical Summary of the Drilling Results

All seven holes intersected the targeted mineralization at depths of 15 to 30 metres below surface. In all cases mineralized core is intensely oxidized with abundant iron oxides. The only sulphide mineral observed was a trace amount of galena.

Individual silver assays ranged from not detected to 3,820 g/t; gold assays ranged from not detected to 0.81 g/t; and lead from <0.01 to 9.20%. The highest grade gold intercept occurred in VG-005 where the included intercept of 2.69 metres averaged 0.72 g/t gold, and the highest lead intercept occurred in VG-002 where the included intercept of 0.89 metres averaged 5.07% lead. At this time, gold and lead values are not viewed as likely to be of economic importance and have not been included in Table 1.

At Julia South the mineralized structure is typically hard and competent and surrounded by competent rock, and core recoveries were high. In Julia Central, core was fractured and faulted in and around the mineralized zone, but core recovery was good. At Julia North the mineralized zone is comprised of hard quartz which has been fractured and faulted and is surrounded by a broad zone of altered and faulted rock which is commonly soft and broken. Core recoveries at Julia North were variable, ranging from 40% to 80%.

Widths of the mineralized intercepts at Julia North are significantly wider than could be anticipated from surface work, because the fault zone which hosts mineralization does not crop out and the faulted material recovered in core contains significant silver values.

Diamond drilling was conducted according to standard industry practices. HQ core was geotechnically and geologically logged and the samples marked prior to systematically photographing the core. Blanks, certified standards and duplicate samples were inserted into the sample stream. A total of 140 samples were submitted from the first seven holes of which 6 were certified standards, 6 were blanks and 6 were ½ core duplicates of the original ½ cores and therefore 18 of the 140 samples, or 12% were control samples. Mirasol contracted sample transportation to an independent third party. Personalized numbered seals were used to assure the chain of custody during transportation. ALS Laboratory Group analyzed the samples for silver and gold by the ME-GRA21 method, which uses fire assay techniques on a 30 gram sample. All samples were also analyzed by the multi-element technique ME-ICP41 and over limits for copper; lead and zinc from those analyses were analyzed by the OG46 method. The results received have passed Mirasol's internal quality control tests.

Paul G. Lhotka, Principal Geologist for Mirasol, is the Qualified Person under NI 43-101 who has approved the technical content of this news release.

Quality Assurance/Quality Control: Exploration at Mirasol's Projects is supervised by Stephen Nano, Vice President of Exploration; Timothy Heenan, Exploration Manager; and Paul Lhotka, Principal Geologist, all qualified persons under NI 43-101. All technical information for the Company's projects is obtained and reported under a formal quality assurance and quality control (QA/QC) program. Rock chip and stream sediment samples are collected under the supervision of Company geologists in accordance with standard industry practice. Samples are dispatched via commercial transport to an ISO 9001:2000-accredited laboratory in Mendoza, Argentina for analysis. Results are routinely examined by an independent geochemist to ensure laboratory performance meets required standards. Neither the TSX Venture Exchange nor its Regulation Services Provider (as that term is defined in the policies of the TSX Venture Exchange) accepts responsibility for the adequacy or accuracy of this release.

Argentex: Silver dominates 2010-2011 exploration program at Pinguino, Santa Cruz, Argentina

VANCOUVER, Dec. 15 /CNW/ - Argentex Mining Corporation (TSX-V: ATX, OTCBB: AGXM) is pleased to announce that its 2010-2011 exploration program has commenced in Santa Cruz province, Patagonia, Argentina. The proposed US$4.0-million program is scheduled to include 17,000 meters of drilling.

The program will focus on the high-grade silver intersections discovered in reconnaissance drilling completed in 2010 in areas such as Tranquilo, Tranquilo Sur and Luna. These veins are all wide open and located within Pinguino's Tranquilo Trend, a prominent regional structure that crosscuts the property over 11 kilometers. Previously published results in these areas include Hole P349-10, which returned a thick 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.

Drilling will initially target these high-grade silver zones from surface to a depth of approximately 50 meters. Our geological modeling predicts a precious-metal enrichment zone near surface. Previously published metallurgical results show the mineralization in this near-surface oxidized zone to have a simple mineralogy and excellent recovery. Additional drill testing within this program is designed to test the deeper extensions of this mineralization.

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 Pinguino's entire system of veins and known targets has been drill tested to date.

"Our goal with this program is to expand the near-surface silver mineralization by approximately 70%," said Ken Hicks, President of Argentex. "As many of the known high-grade silver intersections were only recently discovered, we are excited about the potential to expand these targets."

Pinguino Drilling

Argentex proposes to drill a total of 17,000 meters using a combination of reverse-circulation drilling (13,500 meters) to expand near-surface oxidized silver-gold mineralization and diamond drilling (3,500 meters). The 2010-2011 program is also scheduled to include 12,000 meters of trenching.

Highlights of the 2009-2010 drill program at Pinguino show a very successful first test of silver-gold mineralization and includes intersections such as:





















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 newly tested 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 exploration as well as early-stage projects are also well established in this 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 Alex Stewart (assayers) Argentina S.A. in Mendoza, Argentina.

Marifil Aquires 47,150 Ha of Potash Lands

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

LAS VEGAS, NEVADA--(Marketwire - Dec. 14, 2010) - 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 identification of a large area highly favourable for potash in the northern portion of the basin in Mendoza Province.

The Company has acquired by staking six cateos (claims) totalling 47,150 hectares (471.5 square kilometres) that it believes are highly prospective for potash. The claims, the K3 Project, are also 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 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.

The southern part of the Company's claims lies about 50 kilometers northwest of Vale's giant Rio Potasio potash mine which has a resource of 2 billion tons of potassium chloride.

"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 three of the Company's potash properties, which includes the 80,000 ha K2 project. 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 (www.sedar.com) or at Marifil's Website (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.

Extorre Reports High Grade Gold-Silver Drill Intercepts From the Cerro Moro Project


VANCOUVER, BRITISH COLUMBIA--(Marketwire - Dec. 14, 2010) - Extorre Gold Mines Limited (TSX:XG)(FRANKFURT:E1R)(OTCQX:EXGMF) ("Extorre" or the "Company") is pleased to report assay results from its ongoing drilling program at the Cerro Moro Project, in Santa Cruz Province, Argentina. Recent drilling has focussed on a combination of discovery drilling on new targets and extensions to known mineralization, and infill drilling on existing resource areas. In addition, drilling for infrastructure purposes has also been conducted.

Results from the discovery diamond drilling program on the Gabriela, Escondida, Martina and Loma Escondida zones have been received. Twelve drill holes returned significant results of which 5 holes returned the following intercepts:

* MD1002 (Gabriela) intersected 0.39 metres ("m") at 200.9 grams per metric ton ("g/t") gold + 8,785 g/t silver (347.3 g/t gold equivalent*)
* MD0940 (Escondida) intersected 4.40m at 5.4 g/t gold + 668 g/t silver (16.5 g/t gold equivalent*)
* MD0947 (Escondida) intersected 3.25m at 10.4 g/t gold + 788 g/t silver (23.6 g/t gold equivalent*)
* MD0951 (Escondida) intersected 1.10m at 6.2 g/t gold + 702 g/t silver (17.9 g/t gold equivalent*)
* MD0980 (Martina) intersected 0.73m at 14.3 g/t gold + 10 g/t silver (14.4 g/t gold equivalent*)


Results from 33 drill holes of the infill drilling program at the Gabriela and Loma Escondida zones have also been received, of which 25 have significant results. Highlights from the Loma Escondida zone include:

* MD1030 intersected 0.34m at 74.5 g/t gold + 4,685 g/t silver (88.1 g/t gold equivalent*)
* MD1036 intersected 0.88m at 55.0 g/t gold + 2,408 g/t silver (95.1 g/t gold equivalent*)
* MD1038 intersected 0.50m at 90.4 g/t gold + 6,344 g/t silver (196.1 g/t gold equivalent*)
* MD1046 intersected 0.40m at 74.2 g/t gold + 5,963 g/t silver (173.6 g/t gold equivalent*)


Eric Roth, Extorre´s President and CEO, stated, "Extorre's drilling programs have been designed to both expand Cerro Moro's high grade gold-silver resources and to infill the Inferred category resources that formed part of the Preliminary Economic Assessment ("PEA"). Infill drilling provides the assay data necessary for Inferred category resources to be upgraded, as results allow, to the Indicated category. Indicated resources can ultimately be reclassified as "mineable reserves" in the Pre-Feasibility Study ("PFS").

"Separately, infrastructure drilling for water resources and plant site engineering was completed over the past months as was necessary for the Environmental Impact Assessment ("EIA") and the PEA (currently under review by Santa Cruz authorities).

"With the infill drilling program largely complete, the discovery program is now our highest priority. Up to 4 drill rigs are working on a 24 hours basis to establish additional resources on the property. Drilling is focussing both on new targets such as the Martina and Lucia veins and extensions to existing resource areas at Escondida, Gabriela, and Loma Escondida. Separately, drilling to increase the resource on another vein named the Esperanza zone has now commenced.

"We still have an assay back log amounting to some 100 drill holes. To alleviate this problem we are building an onsite sample preparation facility that will be operated by Acme Laboratories. Construction is underway with startup scheduled for February 2011."














































A discussion of the drilling results follows:

Gabriela Zone Drilling

Extorre's drill strategy at Gabriela has been to expand the existing resource through drilling both at depth and along strike to the southeast, and secondly, to complete infill drilling of the existing resource area for the PFS. New resource drilling continues to confirm continuity of the Gabriela vein to depth, especially beneath the eastern end of the current resource area.

New geological mapping and drilling data suggest that the step-out drill holes designed to extend near surface mineralization to the southeast have been too shallow. Current results suggest that mineralization in this sector has either been faulted downwards or may plunge towards the southeast. Follow-up drilling is a high priority. The infill drill program at Gabriela consisted of 5,383m in 48 holes and focussed on the conversion of the existing Inferred category mineral resource to the higher confidence categories.

Escondida Zone Drilling

Recent drilling at Escondida in the Far West and West sectors has focused on two main areas: a "Gap area", where an unmineralized dyke has been interpreted to cross-cut the highly mineralized Escondida structure, and secondly, step-out drilling to the west along the Fomicruz JV Extension. In the "Gap area", extensions to known high grade gold-silver mineralization were intersected and remain open at depth. Follow-up drilling is planned. On the Fomicruz JV extension, drilling has intersected quartz veining within the Escondida structure, but without the sulphide phase typically associated with high grade gold-silver mineralization. Further drilling in this sector will be undertaken when all the available geological and geochemical data have evaluated.

Martina Zone Drilling

Further high grade mineralization has been intersected at a depth of 220m. Significant results were received from drill hole MD0980, located 160m to the east of previously reported high grade mineralization. Drilling completed 70m below the MD0989 intercept did not intersect significant mineralization, suggesting that high grade mineralization in this zone occurs at 180m to 250m below surface. Follow-up drilling in this depth range is planned.

Loma Escondida Zone Drilling

Drilling has been limited to step-out holes to the west of the existing resource and a short infill program within the known resource. Hole MD0853 was drilled 160m west of the existing resource and approximately 150m to the east of the intersection of the Loma Escondida vein with the Escondida vein. The drill hole successfully intersected high grade gold-silver mineralization, demonstrating the upside potential of the Loma Escondida zone. Follow-up drilling in the MD0853 sector is planned.

The infill drill program at Loma Escondida consisted of 1,567m in 32 holes and focussed on upgrading the existing Inferred category mineral resource to the higher confidence categories. As ore from the Loma Escondida zone is scheduled to be mined early in the Cerro Moro mining schedule, the completion of this infill drill program was considered to be a priority.

Infrastructure Drilling

To complete the EIA and the PEA, 48 drill holes (mostly reverse circulation percussion holes) were completed. Twenty holes were dedicated to sterilization (or condemnation) drilling of the proposed processing plant site and 22 to further evaluate water sources.

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.

Extorre is a Canadian public company listed on the Toronto Stock Exchange (symbol XG) and on the OTCQX (symbol EXGMF). Extorre's assets comprise approximately $46 million in cash, the Cerro Morro and Don Sixto projects, and other mineral exploration properties in Argentina.

On April 19, 2010, Extorre announced an updated National Instrument 43-101 compliant mineral resource estimate for Cerro Moro:

* 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 the future Cerro Moro mine, in which an average of 133,500 gold equivalent* ounces would be produced during the first 5 years of operation at a cash cost of US$ 201 per ounce (net of silver credits). Project CAPEX has been estimated at US$ 131 million (of which 21% is tax that is refundable after production commences), with a payback period of 1.8 years. The project economics were calculated using gold and silver prices of US$ 950/ounce and US$ 16/ounce, respectively.

Extorre also submitted its 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.

GOLDCORP SECURES PERMIT FOR CERRO NEGRO PROJECT

VANCOUVER, Dec. 13 /CNW/ - GOLDCORP INC. (TSX: G, NYSE: GG) and Andean Resources Limited ("Andean") announced today the approval of the Environmental Impact Assessment by the Santa Cruz province in Argentina for the development and production of the Cerro Negro gold project, a high-grade world-class deposit located on the low-elevation Patagonian plains of southern Argentina. The permit enables Goldcorp to commence mine construction immediately following the transfer of ownership on December 30, 2010.

"The successful permitting of Cerro Negro is a positive first step in what we expect will be an efficient and straightforward construction process," said Chuck Jeannes, Goldcorp President and Chief Executive Officer. "Cerro Negro's ideal physical setting and easily accessible veins will result in near-term, cash flow-accretive gold production at a relatively small capital investment. Moreover, recent discoveries of high grade veins and extensions of existing veins form the basis for the analysis of a much larger gold production profile than originally contemplated. We look forward to Cerro Negro's development into Goldcorp's next cornerstone gold asset."

An update to Andean's July 2010 feasibility study is currently underway that will reflect recent drilling success. The update, which is expected to be completed at the end of the first quarter 2011, is analyzing a doubling of mill capacity to approximately 4,000 tonnes per day to process ore mined concurrently from the Eureka and Marianas vein systems. Detailed engineering and subsequent permitting amendment efforts will follow immediately afterward.

The Cerro Negro site team in Argentina continues to make good progress in advancing the project. The decline into the high-grade Eureka vein, which will comprise the first source of mill feed upon initial production in 2013, has reached over 630 meters in length. Upgrades to the main access road and camp expansion will commence early in 2011. Geotechnical work for the mill and associated facilities will commence shortly. Orders for long lead time items including the mills and crushers will be placed following the completion of the feasibility study update at the end of the first quarter of 2011.

Exploration plans for the first half of 2011 include in-fill and extension drilling of the San Marcos vein discovered in late 2009 and the two Mariana veins (Central and Norte) discovered in 2010. Several new prospect areas with known gold mineralization have been identified within the 215 square kilometer property and testing of these new vein targets will commence in the second quarter of 2011. An updated reserve and resource calculation for Cerro Negro will be available in early February with Goldcorp's annual reserve and resource update.

Key dates remaining under the timetable as detailed in the transaction Scheme are as follows:

* December 16, 2010 - Record date for Andean shareholders determining election of cash and shares.
* December 30, 2010 - Scheme implementation; consideration payable delivered to Andean shareholders.

Goldcorp is one of the world's fastest growing senior gold producers. Its low-cost gold production is located in safe jurisdictions in the Americas and remains 100% unhedged.

Malbex Year-End Update


TORONTO, ONTARIO--(Marketwire - Dec. 10, 2010) - Malbex Resources Inc. (TSX VENTURE:MBG) has filed its audited financial statements and MD&A for the year ended September 30, 2010 on SEDAR (www.sedar.com).

"Our first year as a public company was very successful," said Tim Warman, President and CEO. "In our initial drill campaign at Del Carmen Norte, we discovered multiple areas of near-surface gold mineralization and an area of bulk-tonnage style gold mineralization at the Rojo Grande target. Our aim in the current field season is to expand the discovery zone and to complete sufficient drilling to support an initial resource estimate. To that end, we currently have two diamond drill rigs turning at Rojo Grande and anticipate releasing the first tranche of Del Carmen Norte assays in January."

Mr. Warman added, "We will also begin drilling the large geophysical target between Cerro Amarillo and Rojo Grande soon, with the goal of discovering additional areas of bulk-tonnage style mineralization within the 9 km² Del Carmen Norte alteration system. Separately, results are pending for preliminary metallurgical testing of core from last season's drill program at Del Carmen Norte, and the initial assays from the 1,500-metre drill program underway at our Despoblados project."
