Agency: NF Region District: R1 Ranger District: PHILIPSBURG Forest Service Tract: Watershed Code: 17010201 Forest or Resource Area: DEERLODGE Owner: P Impact: L Report: Hidden Lake Mine A caved adit and a caved shaft associated with 2,100 feet of workings (Elliott and others, 1992) spread over a vertical distance of 400-500 feet mark the site of the Hidden Lake Mine. A N47E striking, steeply dipping sheeted zone containing quartz and pyrite was mined (Earll, 1972). Host rock is a klippe of Mount Shields quartzite that was thrust over Paleozoic sedimentary rocks. The thrust may have had a part in localizing the distribution of ore not only at the Hidden Lake Mine, but across the entire Red Lion district. Between 1933 and 1942, 100,000 tons of ore with an average gold content of 0.2 oz/ton was produced. The soft, partially oxidized vein material made milling and extraction easy, but with depth the ore became harder and operations less efficient, contributing to the closure of the mine. The potential for remaining ore and the distribution of gold showings over a wide area surrounding the mine have interested several exploration companies in the past decade. Numerous drill holes were completed, but no results have been released. Hidden Lake Tailings Below the Hidden Lake Mine, tailings are eroding during storm events from a large area of of national forest land. The Hidden Lake was a cyanide mill which processed oxidized ore, and the tailings therefore contain mostly quartz and iron oxide. About 100,000 tons are present at an average grade of <0.006 oz/ton gold, 0.40 oz/ton silver, 0.022% copper, 0.020% lead, and 0.088% zinc. New vegetation is evident on the tailings. |
