TNR Gold CEO Gary Schellenberg Video Interview:  Summary on Los Azules Copper Settlement with McEwen Mining.

         

     Now there is a truly elephant copper discovery in the making with 18.4 billion lb of Copper reported in all resource categories at Los Azules. We can expect very aggressive push from McEwen Mining to market Los Azules and, hopefully, newly discovered mineralised trend and mineralisation at depth will bring this deposit even higher in its world wide ranking.

Update from New McEwen Presentation Feb 6th, 2013

"TNR Gold's primary focus will be the development of Shotgun Gold deposit in Alaska. All other assets will be advanced based on J/V models or converted into the stakes in the companies developing them and/or royalties attributed to them. Good examples of this strategy implemented would be the spinoff company International Lithium Corp. and the retention of royalties from projects it has generated." 

Kirill Klip, Non-Executive Chairman of TNR Gold, stated, "I welcome the positive resolution of the Los Azules litigation in the out of court settlement between TNR Gold and McEwen Mining. I would like personally to thank Rob McEwen as this resolution is a highly beneficial outcome for both our companies. Removing the uncertainty over the rights to Los Azules will allow the project to now achieve its full potential for the benefit of the shareholders of both TNR Gold and McEwen Mining, and I consider our stake in McEwen Mining as a strategic holding for TNR Gold."

TNR Gold Corp. Summarizes Settlement of Lawsuit With McEwen Mining regarding Los Azules Copper Property With Questions & Answers TNR.v, MUX.

"Q: What Does the Los Azules Settlement Mean for TNR Gold?

A: The settlement restores a back-in right to TNR Gold which is exercisable following the completion of a feasibility study. The back-in right allows TNR Gold to back-in for up to 25% of the northern part of the Los Azules property, which is currently believed by McEwen Mining to contain the largest share of the known resource at Los Azules. If TNR Gold elects to back-in for 5% or less, or has its interest diluted to 5% or less, TNR Gold's interest automatically converts to a 0.6% Net Smelter Royalty ("NSR"). TNR Gold's back-in right applies to those properties subject to an Exploration and Option Agreement originally signed by Solitario Argentina S.A. (a subsidiary of TNR Gold) and M.I.M. Argentina Exploraciones S.A. on May 15, 2004 (as amended) (the "Property").

In addition, TNR Gold has been issued 1 million shares in McEwen Mining and delivery of such shares will occur upon the transfer of mineral rights to the Escorpio IV mining tenure to McEwen Mining. The shares are also subject to normal statutory hold periods. (Information about McEwen Mining can be found at http://www.mcewenmining.comand on Sedar at http://www.sedar.com).

TNR Gold and the other parties to the litigation have also dismissed by consent all claims and counterclaims in the litigation.

TNR Gold may decide in the future to realize the value of some or all of the assets received in this settlement. Proceeds realized from such disposition may be used to retire the Company's debt and provide working capital which could reduce the need for future dilution of the Company."

TORONTO, ONTARIO--(Marketwire - Feb. 5, 2013) - McEwen Mining Inc. (NYSE:MUX)(TSX:MUX) is pleased to announce an updated, Canadian National Instrument 43-101 compliant ("NI 43-101") mineral resource estimate for its 100% owned Los Azules Copper Project in San Juan Province, Argentina. Most importantly, drilling has expanded contained copper in the inferred resource category by 29% to 13.95 billion lbs. Contained copper in the indicated resource decreased slightly to 4.45 billion lbs. The expanded resource incorporates 6,966 meters of new drilling from 10 additional holes. The resource remains open laterally, to depth and along strike (to view cross-sections displaying the resource click here). Los Azules is one of the world's largest, undeveloped, high-grade, open pit copper projects which, contains significant growth potential.

"Los Azules is a unique asset, in terms of size and grade, for McEwen Mining. This year's exploration drilling has demonstrated that there is significant potential to expand the resource well beyond our previous understanding of the deposit," stated Rob McEwen , Chief Owner.

Drilling this season represents the first time a meaningful amount of deeper drilling has occurred at Los Azules. Prior to this year the deepest drill hole was 650 meters. This season there has been a total of 6 holes that exceeded 700 meters. This deeper drilling has begun to identify a potential parallel trend, west of the original Los Azules ore-body. Copper mineralization discovered within this trend occurs near surface and also at depth (down to 1,050 meters below surface). This is significant because it may indicate that previous shallow drilling, which makes up the majority of the Los Azules resource, failed to adequately test the deeper potential of the deposit. As a result, many new exploration targets have emerged.

McEwen Mining has begun work on an updated Preliminary Economic Assessment (PEA) which is expected to be completed in the third quarter of this year. The updated PEA will be based on a significantly larger mineral resource and will evaluate the possibility of increasing the daily throughput. The PEA will also incorporate further metallurgical studies currently being done on the possibility of producing copper cathode instead of a concentrate and processing low grade mineralized material not previously considered, via a heap leach. The advantage of producing a copper cathode is that it would eliminate the contemplated slurry pipeline through Chile and would reduce Argentina's export tax on concentrate.

This news release has been submitted by Andrew Elinesky , Vice President - Argentina, for the Company.

About Los Azules

Los Azules is a large undeveloped copper porphyry system located in western San Juan Provincewithin a belt of porphyry copper deposits that straddles the Chilean/Argentine border. This belt contains some of the world's largest copper deposits, including Codelco's El Teniente and Andinamines, Anglo American's Los Bronces mine, Antofagasta PLC's Los Pelambres mine and Xstrata'sEl Pachón project, among others. Los Azules is one of the world's largest, highest grade, undeveloped copper-porphyry deposits not owned by a major base metal company.

*	"Tonnes" is stated in metric and is equivalent to 2205 lbs.
**	Estimated contained metal values may be subject to rounding errors.

Details on the parameters of the resource estimate are as follows:

• The resource estimation was based on data from 173 drill holes comprising a total length of 50,612 meters of drilling completed to the end of December 2012.

• There were a total of 23,178 individual samples selected for analysis. The samples were collected and analyzed in accordance with industry standards. Splits from the drill core samples were submitted to either Alex Stewart in Mendoza or ALS Chemex or ACME inSantiago, Chile for fire assay and ICP analysis. Accuracy of results is tested through the systematic inclusion of standards, blanks and check assays.

• The January 2013 mineral resource estimate for the Los Azules Copper Project was prepared under the direction of Robert Sim , P.Geo. of SIM Geological Inc. The mineral resource estimate uses drill hole sample assay results and the interpretation of a geologic model that relates to the spatial distribution of copper in the deposit. Interpolation characteristics were defined based on the geology, drill hole spacing and geostatistical analysis of the data. Block grade estimates were done using Ordinary Kriging (OK) with a nominal block size measuring 20 meters long, 20 meters wide and 15 meters high. Resources are classified according to their proximity to sample data locations and are reported, as required under NI 43-101, according to the CIM Definition Standards for Mineral Resources and Mineral Reserves.

• Mineral resources, which are not mineral reserves, do not have demonstrated economic viability.

• The quantity and grade of reported Inferred resources are uncertain in nature and there has been insufficient exploration to classify these inferred resources as Indicated or Measured, and it is uncertain if further exploration will result in upgrading them to an Indicated or Measured category.

• As required under NI 43-101, reasonable prospects for economic viability of the mineral resources has been exhibited by the application of a resource limiting pit shell built about copper grades in the model using a projected metal price of US$2.75 per lb. Cu, mining costs of US$1.00 per tonne, milling and G&A costs of US$4.25 per tonne, 100% recoveries and an average pit slope of 34 degrees.

Cautionary Note to U.S. Investors:

McEwen Mining reports its resource estimates in accordance with standards of the Canadian Institute of Mining, Metallurgy and Petroleum referred to in Canadian National Instrument 43-101 ("NI 43-101"). These standards are different from the standards generally permitted in reports filed with the SEC. Under NI 43-101, McEwen Mining reports measured, indicated and inferred resources, measurements which are generally not permitted in filings made with the SEC. According to Canadian NI 43-101 criteria, the estimation of measured resources and indicated resources involve greater uncertainty as to their economic feasibility than the estimation of proven and probable reserves. Under SEC Industry Guide 7 criteria, measured, indicated and inferred resources are considered Mineralized Material. The SEC considers that in addition to greater uncertainty as to the economic feasibility of Mineralized Material compared to proven and probable reserves, there is also greater uncertainty as to the existence of Mineralized Material. U.S. investors are cautioned not to assume that measured or indicated resources will be converted into economically mineable reserves. The estimation of inferred resources involves far greater uncertainty as to their existence and economic viability than the estimation of other categories of resources.
