Our success is driven by our vision, values, and pioneering spirit


The Minto copper-gold mine is located approximately 240km from Yukon’s capital, Whitehorse. The mine ran continuously from 2007 to 2018 and recently resumed operations in October 2019 under new ownership and management after a brief maintenance closure. Since restarting, production and operational efficiencies have been progressively increasing. Minto mine operations are 100% underground and the primary product is copper concentrate, with significant amounts of gold.
