Location: Cobb (1972, MF-413), loc. 32; SW1/4 sec. 1, T. 2 N., R. 1 E., of the Fairbanks Meridian. This mine is on the east side of Twin Creek below the mouth of Skoogy Gulch. Accuracy is within 1,000 feet.
Geology: A number of parallel quartz veins cut granite and carry gold. The granite is also auriferous. The gold in granite is thought to be due to concentration from the brecciated surface portion of the veins. In working a narrow bench placer, it was discovered that the irregular granite bedrock and the adjoining bank contained gold (Chapin, 1914).
Workings: Surface workings of a narrow bench placer deposit were reported (Chapin, 1914).

Commodities (Major) - Au
Development Status: Yes; small
Deposit Model: Intrusion-hosted gold-quartz vein.
