Location and accuracy Spruce Creek has been explored for placer gold for most it length and some parts of it have been mined. One of the areas of activity is what is commonly referred to as the 'Second Basin' at at an elevation of about 750 feet. The placer is about 0.5 mile north-northwest of the center of section 25, T. 49 S., R. 75 E.

Geologic setting

Geologic description

Placer gold was discovered near Windham Bay in 1869, probably in Spruce Creek (Spencer, 1906; Kimble and others, 1984). There was placer mining intermittently on Spruce Creek until the 1950s but most of the production took before 1900 and in the early part of the century. Most of the mining took place in what are called the First and Second Basins. There are no records but the total production from Spruce Creek is probably small.
There was considerable small-scale mining in the Second Basin, most prior to 1900 or in the early part of the 20th century. Details are lacking and there is now little sign of the mine workings (Kimble and others, 1984).

Production and reserves

Workings or exploration The Second Basin was mined beginning in the 1880s and probably into the first decade of the 20th century but details are lacking.
Indication of production Yes; small
Production notes Some but probably small.

Additional comments

Placer claims on Spruce Creek were patented by 1900 and these, as well as one or more patented lode claims, may cover part or all of the Second Basin. However, the surrounding area is now part of the Chuck River Wilderness Area which is closed to prospecting and mining.
