With a hands‑on, technically driven approach, we are advancing both leach and concentrator operations to produce high-quality copper and molybdenum products.

The Reliability Engineer (RE) is responsible for identifying and mitigating risks affecting plant or business operations. This role provides technical expertise to ensure maximum equipment reliability at minimum life cycle cost. The RE works independently or as part of a team, troubleshooting, and identifying root causes. The RE is responsible for evaluating asset/equipment conditions using invasive and non‑invasive practices/technologies to monitor equipment for early signs of deteriorating condition, allowing for early prediction and failure analysis.
