Report: Sirius The Sirius lies near the center of an area of closely spaced veins and relatively pervasive wallrock alteration on a fraction of national forest land almost surrounded by patented claims. The area has been the site of some exploration during the past decade, but no results are available. The Sirius itself drifts along a NE-trending, steeply NW dipping quartz-pyrite-galena-chalcopyrite vein with an ore shoot 175 feet long and 6 inches to 3 feet wide (Roby and others, 1960). Total production since the mine begin working in 1906 has been 446 tons from which 287 oz Au, 5197 oz Ag, 1561 lbs Cu, 73,017 lbs Pb, and 2667 lbs Zn were recovered. Gold values were quite high for a Boulder Batholith vein. Today the caved adit discharges a small amount of acid water, and a large area of contaminated soil extends downslope from the waste rock dump. The dump is composed of 5000 tons of altered quartz monzonite with .040 oz/ton Au, .98 oz/ton Ag, .029% Cu, .91% Pb, and .57% Zn.
