About El Gallo
Located in Mexico
The El Gallo Complex is located in Mexico’s Sinaloa State, along the foothills of the Sierra Madres Occidental mountain range, with a property package including over 1,700 square kilometers of mineral claims. The mine is easily road accessible 20 kilometers NE from the town of Guamuchil.
McEwen Mining purchased El Gallo in 2007, initiated a significant exploration effort and announced the initial silver and gold discovery holes in the complex in November 2008.
The Complex has gold and silver deposits located within a 13 kilometer (8 mile) radius and include the El Gallo and Palmarito silver deposits and the Magistral gold deposit.
The El Gallo Mine achieved first gold pour in September 2012 and commercial production in January 2013. Until June 2018 it operated as an open pit with crushing and heap leach processing, at a capacity of 4,500 tonnes of ore per day, having produced 281,000 gold equivalent ounces at average cash cost of $655 per ounce. Due to the transition to deeper sulfide mineralization that is not amenable to heap leaching, mining and crushing activities ceased in the second quarter of 2018. Residual heap leaching will continue to produce gold for several years.
