Grade Control Geologist Jobs (NOW HIRING)

The Jerritt Canyon deposit was discovered in 1972, and the first gold production from the property occurred in 1981. The Jerritt Canyon property contains 30,821 hectares of mining claims located in the mining-friendly state of Nevada. First Majestic acquired the Jerritt Canyon Gold Mine from Sprott Mining Inc. on April 30, 2021. In May 2023, operations were suspended to prioritize exploration and technical studies. Jerritt Canyon is now entering a new phase of evaluation and planning, requiring substantial technical support to advance the work necessary for a potential future restart of operations.

The Senior Ore Control Geologist is responsible for providing geological leadership and technical expertise to support safe, efficient, and profitable gold production. This role ensures accurate ore definition, grade control, geological interpretation, reconciliation, and short-term mine planning to maximize ore recovery while minimizing dilution and ore loss. Working closely with Mining, Processing, Survey, and Technical Services teams, the Senior Ore Control Geologist provides timely geological information that supports daily production decisions and continuous improvement initiatives.
