Maintenance Manager

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 electric 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 Maintenance Manager will help to oversee the development, design input, and operational execution of maintenance systems (including Mine workshop and ADR plant designs) for the Spring Valley Gold Project.
