El Gallo

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.

Production at El Gallo

From its beginnings in 2012 until 2017, the El Gallo Mine produced 240,000 gold ounces and 125,000 silver ounces. During Q2 2018 mining and crushing activities ceased and contractor equipment has been demobilized from the mine site, with onsite operations further continuing through residual heap leaching. In 2018 El Gallo produced 39,000 ounces of gold and 9,000 ounces of silver from mining and residual heap leaching.

In 2019 the process plant underwent expansions that improved efficiency and enabled faster gold recovery. El Gallo's 2019 residual heap leaching production was of 16,300 gold equivalent ounces. Residual leaching costs in 2019 were $11.6 million, or $688 per gold equivalent ounce sold.

Closure and reclamation at El Gallo are ongoing and residual heap leaching activities will continue to produce gold for several years. At the same time, our team in Mexico is working on a new project for the El Gallo Complex. To find out more information please visit our Fenix project page.
