The Green Gulch 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 (Geology): Age = Quaternary; gravels of the active Green Gulch are Holocene.
Comment (Deposit): Model Name = Alluvial placer Au (Cox and Singer, 1986; model 39a).
Comment (Reserve-Resource): Reserves = Large areas of low-grade, gold-bearing gravels may be present in the area.
Comment (Workings): Workings / Exploration = The area was known as auriferous by 1903. Some claim activity was reported as recently as 1969 when 23 claims were located (Heiner and Porter, 1972, Kardex site Kx 52-308). Their location is very approximate but appears to be near Irish Hill (hill 1335).
Comment (Geology): Geologic Description = An extensive area of auriferous bench gravel was mapped by Collier and others (1908, plate X) west of Washington Creek (NM128) extending south along the west flank of hill 1335. The auriferous area merges with the Sinuk River valley (NM120). Collier and others (1908) reported that good prospects, including recovery of a 0.5-ounce nugget, were found in the bench gravels. Placer gold in Green Gulch could have been reworked from the auriferous bench gravels. Sainsbury and others (1972 [OFR 72-321]) mapped bedrock on hill 1335 as mainly chloritic schist with some marble.
Comment (Reference): Primary Reference = Collier and others, 1908
Comment (Production): Production Notes = Minor production.
Comment (Exploration): Status = Inactive
