McEwen Mining Acquires Property in Nevada

TORONTO, Feb. 24, 2016 (GLOBE NEWSWIRE) -- McEwen Mining Inc. (NYSE:MUX) (TSX:MUX) is pleased to announce that it has completed the purchase of the Afgan-Kobeh property in Nevada for $450,000 in cash. Afgan-Kobeh is an attractive acquisition for McEwen Mining because it hosts a near surface, oxide gold resource in close proximity to our Gold Bar Complex which is expected to begin development in 2017. The objective is to develop the property into a satellite resource that can contribute to the production from Gold Bar. The property has immediate exploration potential with several historical higher-grade drill intersections open laterally and at depth. McEwen Mining plans to conduct a drill program beginning in May 2016 with the objective to increase the known mineralization.

Property Location and Description

The Afgan-Kobeh property is located towards the southeast limit of the Battle Mountain-Eureka-Cortez mineral trend in Eureka County, Nevada. The Afgan deposit is approximately 3 miles (5km) to the southeast of the main ore bodies comprising the Gold Bar Complex (see Fig. 1). Afgan is similar to other sedimentary-rock hosted gold deposits in Nevada in that disseminated and oxidized gold mineralization occurs in the Webb Formation and Devils Gate Limestone lithologies.

Mineral Resource Estimate

A report titled “Updated Technical Report Afgan-Kobeh Property Eureka County, Nevada USA,” dated June 13, 2011, was published by the prior owner in accordance with compliance and disclosure requirements of Canadian National Instrument 43-101 (NI 43-101). Mine Development Associates of Reno, Nevada prepared the technical report that includes a mineral resource estimate for the Afgan deposit using a cutoff grade of 0.006 ounces per ton (opt) or 0.2 grams per tonne (gpt). The mineral resource includes drill information from 181 holes, for a total of 63,303 feet (19,295 meters) of drilling. The summary provided below is for informational purposes only and has not been verified by McEwen Mining.

Exploration Potential

The Afgan deposit is open for possible resource expansion in several areas. Step-out drilling is planned to occur starting in May 2016 and will test areas where the mineralization discovered by earlier drilling remains open (see Fig. 2 and 3). The primary objective of this drilling is to expand the size of the resource. Within the existing resource envelope there is potential to increase grades locally by in-fill drilling, as higher-grade mineralization occurs within relatively confined structurally controlled zones. In-fill drilling is also planned to provide verification of historical results, increase confidence in the resource, and obtain material for column leach testing.

Historical Drill Results

Exploration drilling at Afgan-Kobeh began in 1981, but most of the drilling has occurred since 1990. Data is available for over 200 exploration drill holes, mostly reverse circulation (RC) with some limited core, rotary and air-track also recorded. The table below is a compilation of the best holes in the Afgan deposit (an asterisk denotes holes that are located on Fig. 2). These historical results are provided for informational purposes only, and have not been verified by McEwen Mining.

Metallurgical Testing

A series of sixty-two 48-hour bottle-roll leach tests were conducted on RC drill chips in 2011. Results from this analysis returned consistently good gold recovery averaging 78%, suggesting that the mineralization of the Afgan deposit is amenable to heap leach processing. Column leach tests are planned to determine heap-leaching characteristics once material from core drilling is available for testing.

Corporate Update

McEwen Mining is pleased to provide an update on our financial position. On February 19^th, 2016 we had cash and precious metals of $36.5 million and no debt.
