Geologic setting

Geologic description

The bedrock in the vicinity of Deep Creek consists of volcanic and volcaniclastic rocks, chert, and argillite (Chapman and others, 1985). A Cretaceous or Tertiary monzonite pluton that underlies the headwaters of nearby Esperanto (OP008) and Eldorado creeks (OP007) may extend to the headwaters of Deep Creek. The monzonite contains large feldspar phenocrysts and quartz stockwork veins. At the surface, it is heavily weathered to quartz and feldspar (S. Dashevsky, written communication, 2000).
Between 1916 and 1920, 276 ounces of gold and 23 ounces of silver were mined from Deep Creek (T. Bundtzen, 1987, written communication, 1987).
