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 (Exploration): Status = Inactive

Comment (Geology): Age = Late Cretaceous or younger; the host of mineralization is the Late Cretaceous Willow Creek Pluton.

Comment (Reference): Primary Reference = Ray, 1954

Comment (Workings): Workings / Exploration = Apparently only minor surface prospecting.

Comment (Geology): Geologic Description = Details about the prospect are unavailable. 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 (Deposit): Other Comments = This prospect located from Plate I of Ray (1954), no description of the prospect appears in the text. Ray closes the narrative on lode mines and prospects with: 'Numerous small prospects are scattered throughout the mining district, but aside from those discussed above they have not been sufficiently prospected or are not well enough exposed to justify a description herein.'

Comment (Geology): Age = Host rock is Late Cretaceous.
