Comments
Comment (Exploration): Status = Inactive
Comment (Deposit): Model Name = Placer Au-PGE (Cox and Singer, 1986; model 39a)
Comment (Geology): Geologic Description = Up to 25 feet of muck covered, gold-bearing stream gravels were initially mined in 1901 here (Collier, 1902). The lower part of the mined drainage is cut into alluvial terrace gravels, the Kougarok gravel, (Hopkins, 1963) but most of the mined drainage is on low grade Lower Paleozoic metasedimentary bedrock (Till and others, 1986). Kougarok gravel carries small amounts of gold (Sainsbury and others, 1969; Sainsbury, 1975) but at least part of the gold in Coffee Creek appears to be derived from local bedrock sources. A residual placer contains angular, spongy, and bright gold in 4 to 7 feet of angular schist and quartz and adjacent weathered schist bedrock (Collier and others, 1908) in the headwaters of Wonder Gulch (BN005). Small amounts of cinnabar are present in placer concentrate from Coffee Creek and Wonder Gulch; cerussite and pyromorphite are also present in concentrate from Wonder Gulch (Anderson, 1947).
Comment (Reference): Primary Reference = Cobb, 1975
Comment (Workings): Workings / Exploration = Various combinations of hand, scraper, dozer, dragline, and sluice surface operations have taken place along 8,500 feet of the Coffee Creek drainage and the adjacent 1,000 feet of Dome Creek, and 1,500 feet of Wonder Gulch (Sainsbury and others, 1969). Early mining included winter underground drifting and summer sluicing (Cobb, 1975).
Comment (Geology): Age = Quaternary
