Agency: NF Region District: R1 Ranger District: JEFFERSON Forest Service Tract: Watershed Code: 10020006 Forest or Resource Area: DEERLODGE Owner: M Impact: V Report: Black Bear Two short caved adits discharging water and one flooded shaft comprise the privately held Black Bear. However, the main dump associated with the shaft is partially on Deerlodge National Forest lands. It is composed of 3000 tons of quartz monzonite with abundant pyrite from alteration. Metal content of the dump is .050 oz/ton Au, 2.07 oz ton Ag, .032% Cu, .175% Pb, and .176% Zn. An extensive area of contaminated soil extends from the dump to the nearby creek The mine is located on the Crystal shear zone between the Crystal and the Eva May. It was worked in 1902, 1911, and 1917 with 504 tons of production yielding 64 oz Au, 557 oz Ag, 6720 lbs Cu, 97 lbs Pb, and no Zn (Roby and others, 1960), so it was not a particularly rich mine. Vein minerals are quartz, pyrite, chalcopyrite, galena, and sphalerite. |
