The Buxton Creek placer claims are located at the mouth of Buxton Creek, adjacent to the Quesnel River. Bedrock underlying the claims comprises mainly medium to coarse grained quartz monzonite to granodiorite of probable Cretaceous age which has intruded basalt and fine grained sedimentary rocks of Upper Triassic age.
The claims cover late Tertiary gravels deposited on a bench well above the present level of the Quesnel River. In part, the gravels are related to Buxton Creek fluvial deposition rather than the Quesnel River itself. Gold in these gravels is predominantly coarse, occurring as flattish nuggets. Indicated reserves in 1978 were 306,000 cubic metres grading 4.231 grams per tonne gold (Northern Miner Jan. 19, 1978). A conservative estimate of the grade of the gravels is $21.92 per cubic metre.
"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).
