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 = Yeend, 1991.

Comment (Workings): Workings / Exploration = Good placer gold prospects were reported as early as 1908 in unfrozen gravel less than 8 ft deep (Brooks, 1909, p. 54). In the mid-1980's a rough road was bulldozed from the upper part of Porcupine Creek across the drainage divide and down into the upper part of Loper Creek. Some stripping of muck was done along the margins of Loper Creek, although it is not known if any mining was subsequently done (Yeend, 1991).

Comment (Deposit): Model Name = Placer gold deposit (Cox and Singer, 1986; model 39a)

Comment (Geology): Geologic Description = Loper Creek flows north approximately 17 miles from its headwaters near Pinnel Mountain to its mouth at Preacher Creek. Good placer gold prospects were reported as early as 1908 in unfrozen gravel less than 8 ft deep (Brooks, 1909, p. 54). In the mid-1980's a rough road was bulldozed from the upper part of Porcupine Creek across the drainage divide and down into the upper part of Loper Creek. Some stripping of muck was done along the margins of Loper Creek, although it is not known if any mining was subsequently done (Yeend, 1991).

Comment (Exploration): Status = Inactive
