Location: This small unnamed mine on northwestern Woewodski Island is about 900 feet east-southeast of the mouth of the creek that drains Harvey Lake; it is along a trail from saltwater to the Harvey Lake Forest Service cabin. There are several occurrences of mineralization along the creek from about 800 to 2,000 feet above its mouth. The coordinates are at the location of a small mine dump and mill that was active in the 1930's.

Geology: The rocks in the area consist of silicified and pyritized phyllite and light greenish gray metatuff (?) that is part of the Triassic Hyd Group (Karl and others, 1999). Still and others (2002), guided by an unpublished 1930's-vintage report found several auriferous quartz stringers along about 800 feet of the creek banks and in nearby outcrops; their samples contained up to 1.89 ounce of gold per ton.
There is also a small mill and dump and a small pelton wheel along the creek that probably date to the 1930's. Grab samples of the dump that they thought probably represented the mill feed, contained 5,482 to 7,944 parts per billion. Two shallow holes that were drilled near the dump in 1977 to test the mine did not reveal significant mineralization.

Workings: This mine was active in a small way in the 1930's; a small Pelton wheel and hammer mill remain by a small dump.

Age: Triassic or younger based on the age of the host rock.

Alteration: The Triassic phyllite and metatuff that host the deposit are silicified and pyritized in the area.

Production: Production uncertain but a small amount of gold was probably recovered during the 1930's.

Commodities (Major) - Au
