Location and accuracy A small amount of placer gold was produced in the early 1980's from what is locally called Boulder Creek. The placer is about 0.5 mile north of VABM 'Coke' which is shown on the 1:63,360-scale USGS topographic map. The mine is about about 0.5 mile southwest of the center of section 34, T. 46 S., R. 72 E.

Geologic setting

Geologic description

Gold may have been discovered on what is locally called Boulder Creek as early as 1881 but it was apparently not mined until 1980, when a small cut was worked near the mouth of the creek with a tractor and sluice box (Redman and others, 1989). There is no record of the amount of production but it is probably small. The rocks in the area are mafic volcanic rocks and black phyllite, part of the Permian to Cretaceous metavolcanic unit of Gehrels and Berg (1992).
