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 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' deposits include 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 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. Present activities are limited to residual leaching gold production that is expected to continue together with closure and reclamation activities.

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 heap leaching production was of 8,100 gold equivalent ounces in 2020 and 3,600 gold equivalent ounces in 2021. For 2022, residual heap leaching is expected to produce 1,500 gold equivalent ounces at El Gallo.

Residual heap leaching activities continue with ongoing closure and reclamation work at El Gallo. Our 2021 Sustainability Report for our operations at the El Gallo Complex can be accessed here.

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.
