About Mallay

The Mallay Mine is a past-producing silver mine, fully permitted to restart production. Mallay was built and operated by Buenaventura from 2012 to 2018, with US$115 million of historical investment. The mine went into care and maintenance in 2018 due to low silver prices (~US$16.00 per ounce) and a change in strategic priorities at Buenaventura. Annual production by Buenaventura (2013 to 2017) averaged 1.3 million ounces of silver, 9,100 tonnes of zinc and 6,500 tonnes of lead¹.

The Tres Cerros Project is a highly prospective gold-silver exploration project approximately five kilometers northwest of the Mallay Mine. The project’s prime area of interest is a 2.5 kilometer by 500 meter corridor of gold-silver mineralization and coincident IP/resistivity anomalies, indicative of a bulk tonnage, high sulfidation epithermal system. Numerous historical grab samples were taken across the 2.5 kilometer fault, which are being analyzed to determine further follow-up exploration work.

Further details on the Mallay Mine and Tres Cerros Project are provided in the news release announcing the Acquisition.
