History

Tres Cerros was initially identified by Buenaventura geologists in 2016. Between 2016–2018, over 500 surface samples confirmed consistent gold and silver values over a 2.5 km trend. Despite strong results, the project saw no drilling.

In 2025, Excellon acquired Tres Cerros as part of the Mallay property package. This marks the first time Tres Cerros is being systematically explored with a dedicated program. The project aligns with Excellon’s strategy to advance high-quality precious metal assets in proven jurisdictions.
