Develops an Idaho underground-silver-mine restart, paired with studies of a replacement mill, silver/copper refinery and antimony plant. With no commercial production, its model depends on advancing one concentrated complex toward a final investment decision.
Develops the Sunshine Mine restart in Idaho's Coeur d'Alene Mining District and evaluates an integrated complex comprising a replacement mill, the Sunshine Silver/Copper Refinery and the proposed Sunshine Antimony Plant. The single development asset is intended to yield silver, with prospective copper, lead and antimony by-products; toll processing of third-party antimony concentrates could add a service model.
Maintaining and modernizing the inherited underground complex, completing drilling, and advancing feasibility work are central tasks before any final investment decision. The business has no commercial production or recurring mine revenue, and all material assets are concentrated around Kellogg. Study outcomes, financing, permitting, infrastructure conversion, underground safety and commodity economics shape the operating plan; Electrum's majority voting position makes the issuer a controlled company.
