About Jerritt Canyon

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.

• Provide technical and operational guidance to frontline supervisors, tradespeople, and contractors.
• Work closely with Maintenance Planning and Reliability teams to develop and execute weekly, monthly, and longer-term maintenance plans.
• Ensure maintenance work is properly scoped, scheduled, resourced, and executed.
• Review backlog, deferred maintenance, outstanding work orders, and equipment condition to establish priorities.
• Ensure maintenance work orders, inspections, equipment histories, and other records are completed accurately.
• Coordinate planned equipment shutdowns and major maintenance activities.
• Identify emerging equipment risks and develop mitigation plans before failures impact production or safety.
• Lead, coach, mentor, and develop maintenance supervisors, tradespeople, apprentices, technicians, and contractors.
• Establish clear performance expectations and hold team members accountable for safety, quality, productivity, and conduct.
• Manage workforce allocation, shift coverage, overtime, and contractor resources.
