Workforce
640 people, comprising 290 unionised workers, 110 employees, and 240 contractors.
Overview
The mine is located in northern Mexico in the state of Coahuila, approximately 708 kilometres northeast of Torreon. The property is situated in the municipality of Villa de Ocampo, about 120 kilometres east of the city of Melchor Múzquiz. The site includes 4,076 hectares of mining rights and 1,343 hectares of surface rights.
Production
In 2023, the mine processed 966,392 tonnes of ore, producing 2,718,856 ounces of silver and 321 ounces of gold. In the fourth quarter of 2024, the mine produced 755,963 ounces of silver from 253,953 tonnes of processed ore. The projected production for 2024 is 2.3 million ounces of silver.
