|Location and accuracy||The location given is the confluence of Homestake and Charity Creeks. The location of individual placer operations is unknown.|
Geologic descriptionCharity Creek drains an area underlain by schist intruded by granite (Eberlein and others, 1977). Gravel is 6 to 8 feet deep with little overburden and the pay streak lies throughout the gravel as well as the upper 2 feet of bedrock (Menzie and others, 1983, p. 40). The richest ground was reported to be worth $10 per cubic yard (gold at $300 per troy oz) (Menzie and others, 1983, p. 40). Placer gold was mined by small-scale methods.
