Job description

Solidus Resources is a U.S.-based gold development company backed by Waterton Mining. The company is focused on advancing the Spring Valley Gold Project in Pershing County, Nevada, and specializes in taking high potential gold assets through late-stage development and into production. Solidus applies a technically rigorous, capital-disciplined approach to mine development, with a strong emphasis on environmental stewardship, operational safety, and community engagement.

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. Envisioned as a long-life, low-cost open-pit, heap-leach operation, Spring Valley has a robust resource base and considerable exploration upside along a 7-mile strike length across the Black Ridge fault zone.

With a leadership team experienced in engineering, permitting, and large-scale project execution, Solidus Resources is advancing Spring Valley through feasibility, permitting, and construction, with a clear path toward operational readiness. The company’s goal is to responsibly unlock the value of U.S.-based gold assets while building a reputation for excellence in project delivery and sustainable development.
