|Location and accuracy||Dixon Creek is a north tributarty to the lower Casadepaga River with headwaters against the south side of Mount Dixon. The mouth of Dixon Creek is across the Casadepaga River from the mouth of Thorpe Creek (SO074). This locality is probably located within about 1/2 mile; it is locality 67 of Cobb (1972, MF 445; 1978, OF 78-181).|
Geologic descriptionSmall-scale mining took place on Dixon Creek, probably along the lower part of the creek, as early as 1899 and about 725 ounces are estimated to have been produced by 1907 (Smith, 1910). Some of the gold was coarse. The creek flows close to the contact between Paleozoic marble of Mount Dixon and underlying pelitic schist of possible Cambrian or Precambrian age (Till and others, 1986). The lower part of Dixon Creek crosses a terrace of the Casadepaga River.

|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||Small-scale surface operations took place between 1899 and 1907, probably along lower parts of the creek.|
|Indication of production||Yes; small|
|Production notes||Smith (1910) estimates that about $15,000 (725 ounces) worth of gold were recovered between 1899 and 1907.|
