Location and accuracy Cunningham Creek is a west headwater tributary to Hannum Creek (BN057). Hannum Creek is a west tributary to Inmachuk River. Herried (1966) shows placer mine workings to be present 500 feet downstream of the mouth of Harrys Creek but other workings may be present between here and the confluence with Hannum Creek (Cobb, 1975). This is locality 75 of Cobb (1972; MF 417; 1975; OFR 75-429).

Geologic setting

Geologic description

Placer gold mining took place as early as 1901 on Cunningham Creek when $1,200 (about 70 ounces) was said to have been recovered near its mouth (Moffit, 1905). Herreid (1966) shows placer mine workings to be present 500 feet downstream of the mouth of Harrys Creek but other workings may be present between here and the confluence with Hannum Creek (Cobb, 1975, OFR 75-429). Anderson (1947) reports that a placer concentrate produced by drift mining in 1942 contained lead carbonates, pyromorphite, and galena and assayed 50 % Pb and 5.7 ounces/ton Ag. Mining from near Harrys Creek produced coarse gold and abundant galena and pyrite (Mulligan, 1965). Sulfides are also apparently present in colluvial materials along stream. Galena- and sphalerite-bearing lode deposits are present on Harrys Creek (BN055) and Hannum Creek (BN056). Bedrock of the area is a metasedimentary schist and marble sequence of Lower Paleozoic age (Till and others, 1986). Quaternary/Tertiary basalt flows locally cap ridges along stream valleys.
