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 1: El Gallo 1 achieved its first gold pour in September 2012. Commercial production was accomplished on January 1, 2013. 

In Q1 2014 the El Gallo 1 mine produced 9,365 gold eq. oz (9,295 gold oz and 4,195 silver oz) establishing a new quarterly production record, 38% higher than Q1 2013 and ahead of budget. In 2014, El Gallo 1 is forecasted to produce 37,500 gold equivalent ounces (37,000 gold oz and 25,000 silver oz). Production costs will be reported in May 2014 with Q1 financials.

El Gallo 1 is currently being expanded from 3,000 to 4,500 tonnes per day. The expansion is nearing completion and commissioning is scheduled to start in April 2014. The cost to complete the expansion has been reduced to $3 million from $5 million. The cost is lower than expected due to a large contingency that was initially included but has since been reduced. The increased capacity, combined with higher grades as mining moves deeper in the pit, is expected to increase production from 37,500 gold equivalent ounces in 2013, to 75,000 gold equivalent ounces in 2015. Cash costs and all-in sustaining costs are forecasted to fall from $750 to $575 per gold equivalent ounce and$1,100 to $850 per gold equivalent ounce in 2015.

Key Operational Facts (El Gallo 1)

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 4500 tonnes per day
2013 Production  31,129 gold eq. oz

El Gallo 2: El Gallo 2 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.


On January 21, 2014, the Company announced that the Secretariat of Environment and Natural Resources (SEMARNAT) for the State of Sinaloa, Mexico had approved McEwen Mining'sEnvironmental Impact Statement (EIS) and Change of Land Use permit for El Gallo 2. These are the major permits required before construction can proceed. 

The Company has made a temporary decision to defer the construction of 
El Gallo 2 due to low silver prices. The Company believes silver prices would have to equal $25 per ounce before the rate of return would be high enough to move forward with construction. In order to prepare for a possible construction decision later this year, the Company has been evaluating possible debt financing alternatives while advancing the construction of the ball mill, which is the longest lead time item associated with the project. The ball mill is 60% complete and expected to be delivered in Q3 2014.

Studies have now been completed in order to reduce the estimated capital expenditures associated with El Gallo 2. Approximately $20 million in savings is expected in the following areas: 1) reduction in leach tanks, 2) smaller process plant / refinery, 3) modular crushers, and 4) reduction in transformers. These changes are expected to have minimal impact on annual production. To date$10 million of the final construction cost has been spent. Provided the Company realizes on these projected savings and factoring in the funds that have been spent to date, approximately $150 million would be required in order to complete the mine.

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.
