McEwen Mining Inc.: Los Azules Lawsuit Settled Exploration Moving Ahead Quickly

TORONTO, ONTARIO -- (Marketwire) -- 11/12/12 -- McEwen Mining Inc. (NYSE: MUX)(TSX: MUX) is very pleased to announce that TNR Gold Corp. ("TNR") and McEwen Mining have resolved their differences and settled all outstanding litigation with respect to the Los Azules Copper project located in San Juan Province, Argentina ("Los Azules").

The settlement of this litigation is beneficial in that it provides certainty on the ownership of Los Azules. This allows McEwen Mining to explore areas of the property that were previously contested; as well, evaluate strategic alternatives with respect to the project as a whole.

"This is a very positive development for McEwen Mining, TNR Gold and the Province of San Juan, Argentina. It allows us to accelerate and expand the magnitude of our exploration effort. With this legal obstacle behind us, we are now embarking on the largest drill program in the project's history. We are excited by the potential of growing the size of this world-class copper asset", said Rob McEwen, Chief Owner

The highlights of the settlement:

1. All Litigation has been settled.

2. McEwen Mining has clear title to the Escorpio IV claim.

3. TNR retains a Back-In Right.

4. TNR receives 1,000,000 shares of McEwen Mining.

Details of the Settlement:

1. Litigation Over:

All of the claims and counterclaims brought by TNR and McEwen Mining will either be discontinued or resolved by way of a consent dismissal order.

2. McEwen Mining owns 100% of the Escorpio IV Claim:

TNR will transfer the contested Escorpio IV claim (a mineral claim situated to the west of the deposit) to McEwen Mining. While no mineralization has been found on this property it is best suited for locating all processing and administrative facilities of any future mine development.

3. TNR's Back-In Right:

TNR will retain their Back-in Right for up to 25% of the equity in certain claims comprising the northern portions of Los Azules. These northern claims currently represent approximately 62% of the known resource at Los Azules. This 25% interest, when taken in the context of the whole property, would be currently equivalent to approximately a 15% interest of the total estimated resources at Los Azules (Canadian NI 43-101). This interest could increase or decrease depending on the location and size of future exploration results. The Back-in Right is exercisable after the completion of a bankable feasibility study. To exercise TNR must pay two (2) times the expenses attributable to the back-in percentage (ie. paying 2 x 25% all of the costs attributable to the claims comprising the northern portion of the property). Upon backing-in, TNR may elect to continue to participate in the project or be diluted down to a 0.6% NSR on the same claims comprising the northern portion of the project.

4. TNR to receive 1,000,000 shares of McEwen Mining

As noted in our November 7th news release, drilling began at Los Azules on October 12th. Los Azules is one of the world's largest and highest grade undeveloped copper porphyry deposits. A total of seven drills are operating at the property. The drills are considerably more powerful than the ones used during past field seasons. The Company believes this will increase the likelihood of reaching target depths (+700 meters), where high-grade copper mineralization has been discovered. Initial drill assay results are expected to be released early in 2013. The Company plans to drill approximately 15,000 meters this season.

CAUTIONARY NOTE TO US INVESTORS

McEwen Mining prepares 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. The estimation of measured resources and indicated resources involve greater uncertainty as to their existence and economic feasibility than the estimation of proven and probable reserves. U.S. investors are cautioned not to assume that any part of measured or indicated resources will ever 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.
