Geologic setting

Geologic description

Galena(?), arsenopyrite(?) and gold-colored sulfides were found along the margin of a vuggy, milky-white quartz vein in brecciated silicified country rock. Samples showed 15 ppm Ag and 1,500 ppm Pb (Foster and others, 1984). Bedrock in the Independence Creek drainage is the Lower Schist unit described by Wiltse and others (1995) as a medium to dark gray and medium greenish-gray, fine- to medium-grained, commonly slightly calcareous quartz-muscovite schist, with lesser amounts of quartzose
porphyroblastic albite-chlorite schist and chlorite schist. The bedrock is
cut by numerous quartz veins.
