The Holmes Gulch is a silver and 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 (Deposit): Other Comments = See Hidden Creek (MD066).
Comment (Geology): Geologic Description = The Holmes Gulch placer deposit is in a steep first order stream that can be traced for about one mile (1.6 km). Gravels in Holmes Gulch were 11 ft (3.3 m) deep, and can be traced upstream 4000 ft (1,219 m) toward the Whalen shaft (MD071). Most of the mining took place at the intersection of Holmes Gulch and Hidden Creek. Boulders up to 4 ft in diameter encountered during mining. Age of mineralization is unknown, but is probably Quaternary, based on correlative geomorphological features with other dated placer deposits nearby (Bundtzen and Miller, 1997).
Comment (Deposit): Model Name = Placer Au-PGE (Cox and Singer, 1986; model no. 39c)
Comment (Exploration): Status = Inactive
Comment (Production): Production Notes = The first recorded production from Holmes Gulch took place in 1919; mining continued intermittently until 1938. The production total for Holmes Gulch was 1,065 ounces (33 kg) gold and an unknown amount of silver.
Comment (Reference): Primary Reference = Mertie, 1936
Comment (Workings): Workings / Exploration = Small-scale, surface-hydraulic sluicing predominated. There is no evidence that heavy machinery was employed in Holmes Gulch (Mertie, 1936). Most mining took place at the intersection of Holmes Gulch and Hidden Creek.
