Report: Double Shaft Three caved flooded shafts, 1 open shaft, and several trenches seem to investigate a northeast-trending breccia zone of quartz, siderite, iron oxides, and a trace of pyrite. Although placer workings below terminate at this site, a select breccia sample had less than .006 oz/ton Au and .38 oz/ton Ag. The dumps are composed mostly of unaltered quartz monzonite. Some plagioclase has altered to montmorillonite, and some mafic minerals to siderite. The open shaft to the northwest appears to be on an east-west structure with high-sulfide vein material more typical of the Boulder Batholith. The site is on national forest lands. There were no discharges from the shafts or from trenches at the time of the hydrogeologist's visit; no water or soil samples were collected.
