Welcome to Sierra Metals Inc.

We are a Canadian mining company focused on copper production with additional base and precious metals by-product credits at its Yauricocha Mine in Peru and Bolivar Mine in Mexico. The Company is intent on safely increasing production volume and growing mineral resources. Sierra Metals has recently had several new key discoveries and still has many more exciting brownfield exploration opportunities in Peru and Mexico that are within close proximity to the existing mines. Additionally, the Company has large land packages at each of its mines with several prospective regional targets providing longer-term exploration upside and mineral resource growth potential.
