Gold Bar project is a proposed mine development project consisting of a conventional open pit mine with an oxide gold heap leach recovery circuit. The project is located within the Battle Mountain-Eureka-Cortez gold trend in Eureka County, Central Nevada. The property was previously mined from 1990 to 1994 by Atlas Precious Metals Inc. The nearest operating mines are Barrick Gold's Ruby Hill, which produced 91,000 ounces of gold in 2013 with an all-in-sustaining cost of $877 per ounce and is located approximately 25 miles to the Southeast; and Barrick Gold’s Cortez mine, which produced 1.34 million ounces of gold in 2013 with an all-in-sustaining cost of $433 per ounce and is located approximately 35 miles to the Northwest.
The Gold Bar project is currently in the permitting phase with permits expected to be received in 2016. A pre-feasibility study was completed by SRK Consulting and published in November 2011.
McEwen Mining continues to advance the Gold Bar permitting process for construction and production. Gold Bar is forecasted to produce 50,000 ounces gold per year for 8 years at a cash cost of $700 per ounce and an all-in sustaining cost of $850 per ounce.
Gold Bar has received sufficient underground water rights from the Nevada Division of Water Resources to perform all mine related activities. This permit approval is a significant development for advancing the project.
The Company submitted the Plan of Operations (POO) during the fourth quarter of 2013. The POO was determined complete and the Bureau of Land Management (BLM) has determined that an Environmental Impact Statement (EIS) is necessary to fulfill the requirements under the National Environmental Protection Act (NEPA). Upon completion of the environmental analysis the BLM will be able to proceed with the approval determination of the POO. Stantec Consulting Services based in Reno, Nevada is the third-party contractor that will assist the BLM in the preparation of an EIS for the Gold Bar project. Final permit approval is scheduled for the second quarter of 2016.

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