The Gold Quartz 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.

Alterations
Alteration Type: L
Alteration Text: Wall-rock alteration within a few inches of the veins is intense, but seldom extends more than 10 to 12 inches beyond the quartz filling. Sericitization and carbonate alteration predominate, but there is some pyritization and in the outer parts of the alteration zone chloritization is present (Ray, 1954).

Comments
Comment (Reference): Primary Reference = Capps, 1919
Comment (Workings): Workings / Exploration = Prospected by two tunnels, 20 ft and 212 ft long. Capps (1919) reported that the quartz vein in the longer tunnel is 16 inches thick and pinches out 40 ft from portal. Beyond that point, the tunnel follows a fault zone containing gouge. U.S. Bureau of Mines grab sample of quartz float contained 0.06 ppm (0.002 oz/ton) Au (Kurtak, 1986).
Comment (Deposit): Model Name = Low-sulfide Au-quartz veins (Cox and Singer, 1986; model 36a)
Comment (Exploration): Status = Inactive
Comment (Geology): Geologic Description = Gold-quartz veins cut the Late Cretaceous Willow Creek Pluton. The veins are reported to be up to two feet thick, but pinch out within 40 feet of portal (Capps, 1916; 1919). Wall-rock alteration within a few inches of the veins is intense, but seldom extends more than 10 to 12 inches beyond the quartz filling. Sericitization and carbonate alteration predominate, but there is some pyritization and in the outer parts of the alteration zone chloritization is present (Ray, 1954). A U.S. Bureau of Mines grab sample of quartz float contained 0.06 ppm (0.002 oz/ton) Au (Kurtak, 1986).? 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; veins cut the Late Cretaceous Willow Creek Pluton.
