|Location and accuracy||Goose Creek is a north tributary to the Casadepaga River. The mouth of Goose Creek, at an elevation of about 250 feet, is 2 miles downstream from the mouth of Canyon Creek. This is locality 61 of Cobb (1972, MF 445; 1978, OF 78-181).|
Geologic descriptionPlacer gold mining started on lower Goose Creek in 1900 (Brooks and others, 1901). Dredging started by 1909 and took place intermittently to 1919 (Cobb, 1978, OF 78-181). Sainsbury and others (1972, OFR 511) show placer tailings to be present over the lower mile of the creek. This part of the creek crosses creek terraces and terraces of the Casadepaga River and some bench mining occurred. Near the mouth, bedrock was not exposed and gold was on a clay false bedrock. One half mile upstream, flat, bright gold was recovered from from a clay layer on schist bedrock (Smith, 1910). Bedrock in the area is primarily part of a pelitic schist assemblage of possible Cambrian or Precambrian age (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 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.|
|Workings or exploration||Placer gold mining started on lower Goose Creek in 1900 (Brooks and others, 1901). A water-powered scraper, 1/2 mile above the mouth in 1907, was designed to handle 50 cubic yards per day. Dredging started by 1909 and took place intermittently to 1919 (Cobb, 1978, OF 78-181).|
|Indication of production||Yes; small|
