El Gallo – Mexico

The El Gallo complex is located in Mexico’s Sinaloa State, along the foothills of the Sierra Madres. McEwen Mining announced the initial discovery holes from the El Gallo silver/gold discovery in November 2008. The complex includes the El Gallo and Palmarito silver deposits and the Magistral gold deposit, located within a 13 km (8 mile) radius.

El Gallo Mine: El Gallo Mine achieved first gold pour in September 2012 and commercial production in January 2013. In 2015 the mine had another record production of 63,366 gold equivalent ounces, 64% higher than the previous year. Full year guidance for El Gallo Mine in 2016 is of 55,000 gold equivalent ounces.
Key Operational Facts (El Gallo Mine)

Location Sinaloa State, Mexico
Workforce 350 (including contractors)
Estimated Mine Life Update Pending
Mining Type Open pit
Processing Method Crushing and heap leach
Crushing/Processing Capacity 4,500 tonnes per day
2015 Production  62,967 gold oz & 29,917 silver oz
El Gallo Silver: El Gallo Silver is projected to produce an average of 95,000 gold equivalent ounces per year (5.2 million ounces of silver and 6,100 ounces of gold) at an approximate cash cost of $750 per gold equivalent ounce (including all pre-strip and Mexican royalties). All-in sustaining costs have been estimated at approximately $800 per gold equivalent ounce (including an estimated $5 million per year on exploration). Gold equivalent ounces have been calculated by converting silver into gold using a 60:1 exchange ratio.

The final environmental permit required for the potential construction and operation of El Gallo Silver was received from the SEMARNAT in January 2014. Further, we submitted two additional permits in 2014. The first permit is in relation to the mining of the Palmarito deposit, which represents approximately 15% of the projected annual silver production at El Gallo 2. The second permit relates to the right-of-way for a 13 km electric transmission line that would connect the El Gallo 2 processing plant to the national power grid. In the meantime, construction of the mine could begin with power provided by generators with the option of connecting to the grid when the permit is received. Delays in receiving either of these two these permits would not be expected to delay eventual construction from proceeding.

The ball mill is now complete. Pending a decision to proceed with the development of El Gallo Silver, we are storing the mill at the manufacturer’s facilities.

We are also conducting cost-saving studies to identify opportunities that would allow us to reduce the initial capital investment required while minimizing the impact on potential production. Potential changes include reducing the number of leach tanks and transformers, building a smaller process plant / refinery, and using modular crushers. An updated economic study is scheduled for 2016. 

Current resources for the complex total 893,271 ounces of gold in the measured and indicated categories and 78,480 ounces of gold in the inferred. Silver resources total 63.9 million ounces in the measured and indicated categories and 14.5 million ounces in the inferred.

Cautionary Notes
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.
