Job Description
Drill Operator Job Description Who We Are Andean is a fast-growing precious metals producer operating across top-tier jurisdictions in the Americas. With two cornerstone assets - the San Bartolomé processing facility in Potosí, Bolivia, and the Soledad Mountain Project in Kern County, California - we are expanding our footprint and shaping the future of responsible mining.
