Prior to 1968, there are records of mining by previous owners, including a man and wife team who wintered on the mountain, and hauled their stockpiled ore to the railroad in the spring. The stibnite veins are narrow, and relatively flat lying with a dip of approximately 25 degrees with strike lengths in excess of 4,500 feet. Beginning in 2025, a USAC team, led by consulting geologist Peter Mejstrick, researched company and Montana Tech records, conducted field prospecting programs, and confirmed that a substantial quantity of stibnite remained on the mountain. The team developed a plan to resume mining, but to approach the challenge with a surface mining method utilizing modern hydraulic excavators not available to previous operators. The "cut and cover" method that was developed enables the removal of the overburden and then the vein of stibnite in panels, that are subsequently covered by the overburden excavated from the next adjacent panel.","length":1196,"tagName":"p"},{"type":"text","content":"Current Operations","length":18,"tagName":"p","attribs":{}},{"type":"text","content":"An application to modify the company's operating plan was made to the Hard Rock Mining Bureau of the Montana Department of Environmental Quality and the changes...
