Sr. Mine Engineer

Posted Tuesday, June 30, 2026 at 4:00 AM Summary: Solidus Resources is a U.S.-based gold development company backed by Waterton Mining. The Spring Valley Gold Project is located in the prolific Humboldt Range, an area with approximately 60 million ounces of gold endowment within a 50-mile radius. The Spring Valley Project is a large-scale open pit gold heap leach operation, with a >10 year mine life and a production profile in excess of 300,000 oz annually. Using 300-ton class autonomous mining haul trucks and hydraulic shovels, the higher-grade ore will be crushed in a 13 Mst/a three stage crushing facility with a ½” product size that is conveyed and placed on the heap leach pad with stackers, while the low-grade run-of-mine ore will be directly stacked using the mine truck fleet. The conventional heap leach pad is segregated into these two operating areas where it will be irrigated, with leach solutions collected and processed into dore bars through the ADR facility. Site infrastructure to support the operation such as haul roads, waste rock storage facilities, truck shops, water management, warehouses, offices, etc are also included in the project scope. Position Overview: The Sr. Mine Engineer is responsible for developing and delivering executable mine plans aligned with the Life of Mine (LoM) strategy and annual budgets. This role ensures optimal production, cost efficiency, and consistent ore feed to the leach facility for a large-scale open pit operation. The position plays a key role in advancing a digitally enabled, autonomous mining environment through data-driven planning, system integration, and cross-functional collaboration.
