Guadalupe y Calvo is an advanced silver-gold exploration project in the historic Guadalupe y Calvo mining district in the state of Chihuahua. It lies approximately 300 kilometres southwest of the city of Chihuahua. The town and district are located in the rugged Sierra Madre Occidental mountain range, but many parts of the property are accessible by road.

The property exhibits classic low-sulphidation epithermal gold-silver mineralization, with quartz veins, quartz breccias, and stockworks that host economically significant gold and silver deposits. The main structural feature is the Rosario fault complex. The width of the mineralized zone in this complex is up to 80 metres.

Guadalupe y Calvo, known for the historic Rosario mine, once produced 28 million ounces of silver and 2 million ounces of gold. High-grade goldsilver veins up to 10 metres in width were worked here. From 2003 to 2010, 54,418 metres were drilled in 189 holes to delineate a highgrade ore shoot along strike from the historic Rosario mine. Guadalupe y Calvo has potential to increase our silver and gold resources and to become a high-grade gold and silver mine.
