Pmrgx-3

The Pmrgx-3 is a gold and silver 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 (Exploration): Status = Inactive

Comment (Reference): Primary Reference = Christie, 1974

Comment (Geology): Age = Eocene or younger.

Comment (Workings): Workings / Exploration = An Aleut-Quintana-Duval joint venture carried out brief reconnaissance mapping and sampling in 1974 (Christie, 1974). Only minor amounts of base and precious metals were found. UNC Teton Exploration Drilling Company geologists examined the site during the period 1979-1981. They called it a 'smoker-type' occurrence, but found little of interest. Samples collected by the U.S. Geological Survey in the mid-1980s were reported to be anomalous in antimony, copper, gold, lead, silver, and tin (Wilson and others, 1988).

Comment (Geology): Geologic Description = This occurrence consists of a 1- by 2-mile color anomaly (Christie, 1974, color anomaly 80). At this site, Christie noted 6-inch to 3-foot-thick 'beds' of intensely argillized volcanic rock containing as much as 20 percent pyrite. The average pyrite content is 2 to 5 percent. A fractured diorite dike containing disseminated pyrite also crops out in the area. Two rock samples collected by Christie in 1974 contained as much as 0.01 ppm gold, 2.1 ppm silver, 98 ppm copper, 49 ppm zinc, and 1.6 ppm molybdenum. The country rocks are mapped as Eocene to Oligocene Popof volcanic rocks (Wilson and others, 1995). Six rock samples collected by the U.S. Geological Survey in the mid-1980s were reported to be anomalous in antimony, copper, gold, lead, silver, and tin (Wilson and others, 1988).

Comment (Deposit): Other Comments = the site is located on land patented by, or interim-conveyed to, the Aleut Corporation.
