In 1933, the claims were owned by Helbarth Lepsoe (Hill, 1933, p. 152).
Location: The Lepsoe prospect is at an elevation of 1,600 to 1,800 feet along the ridge northeast of Nugget Creek (Hill, 1933, p. 152). It is approximately 1.5 miles north-northwest of the top of Ester Dome, in the SW1/4 sec. 24, T. 1 N., R. 3 W., Fairbanks Meridian.
Geology: Claims were staked on a 20-foot-wide quartz vein that strikes N. 40 W. and parallels a granite porphyry dike (Hill, 1933, p. 152). The Cretaceous granite has intruded the Fairbanks Schist, which is composed of quartz-muscovite schist, quartzite, and chlorite-quartz schist (Newberry and others, 1996).
Workings: Two claims were staked prior to 1933, but very little work was done (Hill, 1933, p. 152).
Age: Associated with a Cretaceous granite porphyry dike.
Commodities (Major) - Au
Development Status: None
Deposit Model: Gold-quartz vein associated with a granite porphyry dike
