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 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 Fixed Plant Superintendent is responsible for establishing and leading maintenance activities for a new crushing, conveying, and gold processing operation. This role will build maintenance systems, recruit and develop the maintenance team, implement reliability-centered maintenance practices, and ensure the safe, efficient, and reliable operation of the fixed plant, ADR (Adsorption, Desorption, Recovery) process plant, and associated heap leach facilities. The successful candidate will play a key role in commissioning, startup, and the long-term reliability of critical processing infrastructure. Job Responsibilities Lead maintenance activities across the crushing, conveying, ADR process plant, and heap leach facilities to maximize equipment reliability and availability. Develop and implement preventive, predictive, and reliability-centered maintenance programs. Support commissioning, startup, and maintenance readiness for the new facility. Oversee maintenance of fixed plant equipment, including crushers, conveyors, pumps, piping, hydraulic and lubrication systems, electrical and instrumentation systems, leach solution distribution, carbon handling, elution circuits, electrowinning, reagent systems, and related infrastructure. Implement condition monitoring programs, including vibration analysis, thermography, and oil analysis. Build, mentor, and lead a high-performing maintenance team while managing contractors and external service providers. Establish maintenance procedures, SOPs, asset registers, and CMMS standards. Plan maintenance resources, spare parts, tooling, and contractor support. Monitor maintenance KPIs, including equipment availability, MTBF, MTTR, backlog, and costs. Partner with operations, engineering, metallurgy, and project teams to improve plant reliability and performance. Drive continuous improvement initiatives while ensuring compliance with all safety, environmental, and regulatory requirements. Qualifications 10+ years of maintenance experience in mining, mineral processing, gold processing, aggregates, or another heavy industrial environment. 5+ years of maintenance leadership experience. Experience maintaining crushing, conveying, and fixed plant equipment. Experience supporting ADR process plants, heap leach operations, or other gold recovery processes is highly desirable. Strong knowledge of preventive, predictive, and reliability-centered maintenance practices. Experience with CMMS systems. Greenfield or commissioning experience preferred. Mechanical trade certification, technical diploma, or related degree is an asset. Strong leadership, communication, planning, and problem-solving skills. Valid driver's license. Demonstrated commitment to safety and continuous improvement.
