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 land package is located 4 kilometers from the town of Mocorito and is easily accessible by road.

McEwen Mining acquired 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 includes the El Gallo and Palmarito silver deposits and the Magistral gold deposit, all located within a 13-kilometer (8-mile) radius.

The El Gallo Mine had the first gold pour in September 2012 and achieved 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 279,000 ounces of gold and 134,000 ounces of silver for 281,000 gold equivalent ounces at an 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. Activities from mid-2018 to mid-2022 were gold and silver residual leaching production that continued together with closure and reclamation work.

Our team in Mexico is also working on a new project for the El Gallo Complex. To find out more information please visit our Fenix project page.

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. Production was of 8,100 gold equivalent ounces in 2020, 3,600 gold equivalent ounces in 2021 and 612 gold equivalent ounces in 2022, when the residual heap leaching process continued until July.

Our team in Mexico continues the work on the Fenix project and on closure and reclamation. The 2021 Sustainability Report for our operations at El Gallo can be accessed here.
