Comments on the geologic information

  • Geologic Description = Gold was discovered on Hannum Creek in 1900 (Moffit, 1905) and placer mining has occurred for over 4 miles of the channel, from the mouth of Collins Creek upstream to the confluence with Cunningham Creek. Gold is irregularly distributed on schist bedrock that is locally decomposed to blue clay. Gravels in the creek are 2-6 ft thick and the paystreak was 6 inches to 4 feet thick, with widths up to 100 feet. Galena (with hematite and pyrite) was recognized in early in placer concentrate (Moffit, 1905) and cassiterite was reported in 1947 (Anderson, 1947). Galena- and sphalerite-bearing lode deposits are present in headwaters to Hannum Creek (BN056) and Cunningham Creel (Harrys Creek, BN055). Bedrock of the area is a metasedimentary schist and marble sequence of Lower Paleozoic age (Till and others, 1986). Quaternary/Teritiary basalt flows locally cap ridges along the Hannum Creek valley.
