Role

We are seeking a Senior Process Metallurgist to join our Engineering Department. In this role, you will be responsible for helping commission the start-up of the Thacker Pass Mine and Lithium Processing Facility and help continually improve the operation of the Lithium Processing facility. This role plays a critical part in transforming ore into high-quality lithium products by integrating metallurgical expertise with plant operations, data analytics, and production planning.

The Senior Process Metallurgist will lead metallurgical performance monitoring, test work, aid in forecasting, and reconciliation across the mine and processing facilities, ensuring recovery, throughput, and product quality targets are achieved safely, reliably, and sustainably. Working closely with Operations, Mining, Engineering, Maintenance, and Commissioning teams, this role helps bridge the gap between planning, plant performance, and life-of-mine production objectives.

The role is based at our Thacker Pass location and reports to the Site Engineering Manager. Occasional travel to other LAC offices, project sites, vendor, or other locations may be required.
