Agency: NF Region District: R1 Ranger District: JEFFERSON Forest Service Tract: Watershed Code: 10020006 Forest or Resource Area: DEERLODGE Owner: N Impact: Report: Gray Lead The Gray Lead includes an open adit with a discharge and 800 feet of total workings that apparently cross cut to a low grade quartz-tourmaline-pyrite vein in quartz monzonite with quartz, sericite, and pyrite alteration products. Mining from 1928-1949 produced 2235 tons of ore which yielded only 135 oz Au, 775 oz Ag, 104 lbs Cu, 27,308 lbs Pb, and 31 lbs Zn (Roby and others, 1963). A gravity mill operated on the site and produced about 800 tons of tailings with .022oz/ton Au, .97 oz/ton Ag, .035% Cu, 1.15% Pb, and .093% Zn. Seeps issue from the tailings and impact vegetation in a wetland downstream. The dumps are mostly unaltered quartz monzonite, and even the altered monzonite present contains very low metal values (see map). |
