Location and accuracy Near the turn of the century, the Chuck River was explored for placer gold and mined at several locations scattered for about 10 miles above its mouth. There is little specific information where this mining took place and the site is plotted about 5 miles above its mouth, in section 24, T. 50 S., R. 75 E.

Geologic setting

Geologic description

In about 1900, the Chuck River was extensively prospected for placer gold and about 25 claims were staked (Spencer, 1906; Kimble and others, 1984). Most of the claims were about 3, 5, and 10 miles above its mouth and a diversion tunnel was driven about 8 miles above its mouth to mine a horseshoe bend in the river. There are no records of production and if there was any, it was probably small.
