About us
A Canadian explorer chasing significant silver, gold & copper discoveries.
Metalero holds ~230 km² on strike with the San Cristobal Mine — one of the five largest silver mines on Earth — in Bolivia’s underexplored Uyuni belt, plus a 173 km² copper-gold land package along the Mount Polley trend in British Columbia.
As a member of the Metals Group, the company is tightly held, insider-aligned, and moving toward its first modern exploration on ground that has never been tested with today’s geoscience.
