Location: This prospect is about 1.1 mile west-southwest of the head of Twelvemile Arm and about 0.2 mile east of the northwest corner of section 26, T. 75 S., R. 83 E. This is locality 2 of Herreid and Rose (1966), who suggest that it may be the Dolly Varden prospect. However, that prospect is probably about 3 miles to the east (CR110).
Geology: As described by Herreid and Rose (1966), this prospect consists of an 18-foot adit and an 8-foot winze driven on a calcite vein. There are apparently no ore minerals in the vein. The rocks in the vicinity are interbedded marble, greenstone, and greenschist of the Wales Group of Cambrian and older age (Eberlein and others, 1983; Brew, 1996).
Workings: An 18-foot adit and an 8-foot winze.
Age: This apparently unmineralized quartz vein is in marble, greenstone, and greenschist of Cambrian or older age.
Deposit Model: Questionable deposit.
