Location and accuracy Kasson Creek is a headwater tributary of Shovel Creek (SO017), about 3.8 miles northwest of Quigleys Camp on the Solomon River. Placer mining has occurred for 1 mile upstream of the mouth at an elevation of about 250 feet. This is locality 89 of Cobb (1972, MF 445; 1978, OF 78-181).

Geologic setting

Geologic description

The bedrock along this part of Kasson Creek is marble and gold was found in crevices and pockets from 10 to 30 feet deep; pay streaks were from 16 to 100 feet wide (Collier and others, 1908). The spotty, deep character of the deposits suggests that karst features as at Daniels Creek (SO006) controlled gold deposition (Cobb, 1978, OF 78-181). Smith (1910) notes that gravels are practically absent and that, at least locally, 3 feet of fine sand is present on bedrock. The recovered gold is reported to be fine and well rounded although some is relatively coarse (Smith, 1910). Asher (1969, DGGS R33) collected a float sample of limonite-stained calcareous schist with disseminated sulfides that assayed 0.07 ounces gold per ton. Bedrock is part of a lower Paleozoic metasedimentary assemblage (Sainsbury and others, 1972, OFR 511; Till and others, 1986).

Mineral deposit model Placer Au-PGE (Cox and Singer, 1986; model 39a).
Mineral deposit model number 39a
Age of mineralization Quaternary; the location and elevation of about 250 feet indicate that these placer deposits may have been influenced by Quaternary sea level fluctuations (also see Problem Creek, SO170).

Production and reserves

Workings or exploration The creek was mined in early years mostly by small-scale hand methods; open-cut dozer (?) operations took place in the 1930s (Cobb, 1978, OF 78-181). Some early mining may have also taken place on two tributaries to Kasson Creek, Lost and Topnotch Creeks (Smith, 1910).
Indication of production Yes; small
