Placer gold deposits of the Quesnel Highland region, including the former rich producers of the Barkerville Camp, have accounted for a large proportion of British Columbia's alluvial gold production. With the exception of a few producers in the Wingdam area, which are underlain by Upper Triassic sediments correlative with the Nicola Group, almost all the deposits are underlain by the Upper Proterozoic to Lower Paleozoic Snowshoe Group. These predominantly metasedimentary rocks have been metamorphosed to greenschist facies.

Placer gold deposits in the region are generally found in relatively young Pleistocene gravels. The morphology and mineral associations of the gold suggests that it was derived locally, the most obvious sources are the numerous auriferous veins in the Downey succession of the Snowshoe Group.

The main placer gold production from Conklin Gulch apparently took place prior to 1900. Recorded production from 1874-90 totalled 228,336 grams gold (Bulletin 28). The valley was known to be gold-bearing for almost 3000 metres upstream from the confluence with Williams Creek. However, the richest claims were located near the mouth. Mining took place on a buried channel which is about 30 metres deep near the mouth and decreases in depth upstream. There was a considerable amount of underground work done but most of the production was probably by hydraulicking. The area is underlain mainly by Snowshoe Group rocks; the contact with the Slide Mountain Group is nearby.

"Data from the Cariboo mining district indicate that supergene leaching of gold dispersed within massive sulphides by Tertiary deep weathering followed by Cenozoic erosion is the most likely explanation for the occurrence of coarse gold nuggets in Quaternary sediments" (Exploration in British Columbia 1989, page 147).
