Location and accuracy Sunshine Creek is a north tributary to Canyon Creek (SO083). The mouth of Sunshine Creek is 1.2 miles upstream from the confluence of Canyon Creek and the Casadepaga River. This is locality 52 of Cobb (1972, MF 445; 1978, OF 78-181).

Geologic setting

Geologic description

The lower part of Sunshine Creek crosses benches of Canyon Creek; Sainsbury and others (1972, OFR 511) show placer tailings along the lower 0.5 mile of the creek. There are reports of placer mining here in 1918 and 1934 (Cobb, 1978, OF 78-181). Smith (1910) notes that placers along north tributaries of Canyon Creek derive ther gold from reworking the bench gravels. Bedrock of the area includes a pelitic schist of possible Cambrian or Precambrian age in contact with a lower Paleozoic metasedimentary assemblage to the west in the headwaters of Canyon Creek (Till and others, 1986).

Mineral deposit model number 39a
Age of mineralization Quaternary; the numerous incised terraces along the Casadepaga River indicate that more than one cycle of erosion and deposition has developed placer deposits in the area. The low elevations between 170 and 270 feet along the first 11 miles of the river, suggest that Quaternary sea level fluctuations could have influenced placer development.

Production and reserves

Workings or exploration Small-scale open-cut placer mining took place intermittently from at least 1918 to 1934 along the lower 0.5 mile of the creek.
Indication of production Yes; small
