TNR Gold Corp. Advises of McEwen Mining's Increased Resource Estimate for Los Azules Copper Project

Vancouver B.C., May 16, 2013: TNR Gold Corp. (the "Company" or "TNR") advises that McEwen Mining Inc. (NYSE:MUX, TSX:MUX) ("McEwen Mining") has issued a news release dated May 15, 2013 in relation to the Los Azules Copper Project in San Juan Province, Argentina. TNR holds a 25% back-in right, exercisable upon the completion of a feasibility study, on the northern part of the Los Azules property.

The news release issued by McEwen Mining summarizes an updated mineral resource estimate completed on the property. In their press release McEwen Mining states, "Key developments include the successful conversion of inferred resources into the indicated category while increasing the size of the resource. The resource remains open along strike, to depth, and laterally." The news release is available at SEDAR http://www.sedar.com and onhttp://www.mcewenmining.com. TNR encourages its shareholders to read the press release issued by McEwen Mining to gain a better understanding of the work performed and the potential impacts this will have on the project. McEwen Mining has also stated that an updated preliminary economic assessment ("PEA") will be completed later this year that will utilize the expanded resource and "will evaluate the possibility of: (1) increasing the daily throughput; (2) producing copper cathode instead of a concentrate and (3) processing low-grade mineralized material not previously considered, via a heap leach".

McEwen Mining's press release appears to be prepared by Qualified Persons and the procedures, methodology and key assumptions disclosed therein are those adopted and consistently applied in the mining industry, but no Qualified Person engaged by TNR Gold Corp. has done sufficient work to analyze, interpret, classify or verify McEwen Mining's information to determine the current mineral reserve or resource or other information referred to in the press release. Accordingly, the reader is cautioned in placing any reliance on the disclosures therein.

The Company has a 25% back-in right in the northern portion of the Los Azules property which is exercisable following the completion of a feasibility study. If the Company elects to back-in for 5% or less or has its interest diluted to 5% or less, TNR will receive a net smelter royalty of 0.6% from the Northern Portion.

The Los Azules copper deposit is located in the San Juan province of Argentina. McEwen Mining Inc. is the current operator on the Los Azules copper deposit and the Company has previously advised that on March 13 and March 28, 2013, McEwen Mining Inc. issued press releases in relation to the deposit, which are accessible on Sedar at http://www.sedar.com and on McEwen Mining Inc's website at http://mcewenmining.com.

Over the past twenty-one years TNR, through its lead generator business model, has been successful in generating high quality exploration projects around the globe. With the Company's expertise, resources and industry network, it is well positioned to aggressively identify, source, explore, partner and continue to expand its project portfolio.

TNR is also a major shareholder of International Lithium Corp. (TSX:ILC.V) ("ILC"), a company created by TNR to advance its internationally acquired lithium prospects. TNR currently holds about 25.5% of the outstanding shares of ILC.

TORONTO, ONTARIO--(Marketwired - May 15, 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. Key developments include the successful conversion of inferred resources into the indicated category while increasing the size of the resource. The resource remains open along strike, to depth, and laterally. Los Azules ranks as one of the world's largest, undeveloped, high-grade, open pit copper projects, and appears to have significant growth potential.

Table 1. Los Azules Copper Project - Comparison of Previous and Current Mineral Resource Estimates

"This Resource Estimate Update marks the completion of our most successful drilling season at Los Azules. We discovered a new parallel zone to the west and significantly increased the Indicated Resource and Inferred Resource Estimates. Congratulations are in order to our exploration team in Argentina who set a record for the number of pounds discovered at Los Azules in one drill season,"statedRob McEwen, Chief Owner.

This season's exploration effort focused on expanding the resource base. A total of 15,800 meters of drilling was completed which produced a 17% increase in contained copper in the Indicated Resource category, to 5.4 billion lbs of copper and a 32% increase in contained copper in the Inferred Resource category, to 14.3 billion lbs of copper, since the June 2012 estimate of mineral resources. On February 5, 2013, we released an interim, mid-season resource update (to view click here). Table 1 shows a comparison of the new (May 2013) resource with the resource estimated at the end of last year's drilling program (June 2012).

This updated resource estimate will form the basis of a new Preliminary Economic Assessment (PEA), which is expected to be completed in the third quarter of 2013. This PEA will evaluate the possibility of: (1) increasing the daily throughput; (2) producing copper cathode instead of a concentrate and (3) processing low-grade mineralized material not previously considered, via a heap leach.

The advantages of being able to produce a copper cathode rather than a copper concentrate is two fold: First, it would eliminate the capital intensive, concentrate pipeline through Chile; and second, it would reduce the applicable export tax by 50%.

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'sLos 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 metals company.

Table 2. Los Azules Mineral Resource Estimate

In order to exhibit reasonable prospects for economic viability, the mineral resource estimate has been contained within a conceptual open pit shell generated using general technical and economic parameters that are defined at the end of this news release. For comparison purposes, resources are listed at a series of cut-off grades in Table 2. The Base Case cut-off grade of 0.35% Cu is highlighted in the table below.

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

• The resource estimate is based on data from 185 drill holes comprising a total length of 59,518 meters of drilling completed to the end of March 2013.
• There were a total of 27,688 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 eitherAlex Stewartin 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 May 2013 mineral resource estimate for the Los Azules Copper Project was prepared under the direction ofRobert 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.

Lomiko Metals has made its way up to the FT article on graphene: company has a lot of potential, but capital will be needed for the next step. With all that interest to the graphite and graphene now, to raise announced 500,000 should not be a problem and we are looking forward to this confirmation. Now talk is very cheap in the junior mining market and only solid backers can make the future for any company.

Strong strategic partner with deep pockets can make all the difference here.

LOMIKO ADDS GRAPHENE EXPERTS DR. POLYAKOVA AND DR. STOLYAROV TO ADVSIORY BOARD

"Lomiko Metals was on fire last week and we have the Volume Buy signal now - will the company be able finally to defy the gravitation of "the dead junior market" remains to be seen, but the Company has the goods now and it is building the buzz around its very interesting Graphene opportunity. Few latest presentations by Lomiko Metals CEO Paul Gill will help you to dig into this story. BNN will put this company under the spot light and we like to see in the latest News Release that company is looking for the Strategic Investor for its vertically integrated Graphite and Graphene business model."

"Now Lomiko Metals has the goods to deliver for its Graphite and Graphene Investors. Strategic Investor with the deep pocket to develop the property will be ideally the next step to reposition this company to the different valuation league. Results from the property speak for themselves this time and market takes notice."
