The Lepsoe is a gold mine located in Alaska.
About the MRDS Data:
All mine locations were obtained from the USGS Mineral Resources Data System. The locations and other information in this database have not been verified for accuracy. It should be assumed that all mines are on private property.
Mine Info
Satelite View
MRDS mine locations are often very general, and in some cases are incorrect. Some mine remains have been covered or removed by modern industrial activity or by development of things like housing. The satellite view offers a quick glimpse as to whether the MRDS location corresponds to visible mine remains.

Comments
Comment (Reference): Primary Reference = Hill, 1933
Comment (Workings): Workings / Exploration = Two claims were staked prior to 1933, but very little work was done (Hill, 1933, p. 152).
Comment (Geology): Geologic Description = 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).
Comment (Deposit): Other Comments = In 1933, the claims were owned by Helbarth Lepsoe (Hill, 1933, p. 152).
Comment (Deposit): Model Name = Gold-quartz vein associated with a granite porphyry dike
Comment (Exploration): Status = Inactive
Comment (Geology): Age = Associated with a Cretaceous granite porphyry dike.
