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 (Workings): Workings / Exploration = Apparently only minor surface prospecting.
Comment (Exploration): Status = Inactive
Comment (Geology): Geologic Description = Details about the prospect are scarce. Most likely, a gold-bearing quartz vein(s) cuts the Late Cretaceous Willow Creek Pluton. The Willow Creek Pluton is a zoned pluton. The outer part consists of hornblende quartz diorite and lesser hornblende tonalite; the core consists of hornblende-biotite granodiorite, and lesser hornblende-biotite quartz monzodiorite and biotite quartz monzonite.
Comment (Geology): Age = Late Cretaceous or younger; the host of mineralization is the Late Cretaceous Willow Creek Pluton.
Comment (Reference): Primary Reference = Stoll, 1997
Comment (Deposit): Other Comments = This prospect was originally part of the Gold Top (ARDF number AN014) claims.
Comment (Production): Production Notes = Knik miner Milo Kelly recovered about 60 ounces of gold from a few hundred pounds of ore mined from shallow workings on the Gray Eagle property (Vinal, 1940).
Comment (Deposit): Model Name = Low-sulfide Au-quartz veins ? (Cox and Singer, 1986; model 36a ?)
Comment (Geology): Age = Late Cretaceous or younger; the host of mineralization is the Late Cretaceous Willow Creek Pluton.
