Unnamed (near VABM 592, south of Banner Peak)

The Unnamed (near VABM 592, south of Banner Peak) 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 = Mid-Cretaceous or younger; superimposed on schist metamorphosed during the mid-Cretaceous.

Comment (Workings): Workings / Exploration = Old exploration pits and trenches are of pre-1920 vintage. A soil geochemical survey was completed in 1990 by BHP, and trenching and drilling was done in 1992 by Newmont Mining Company.

Comment (Exploration): Status = Inactive

Comment (Reference): Primary Reference = This report

Comment (Deposit): Model Name = Albitic replacements in schist; allied to Low-sulfide Au-quartz veins (Cox and Singer, 1986; model 36a).

Comment (Geology): Geologic Description = Hummel (1962 [MF 247]) described old prospect pits south of Banner Peak near hill elevation 592 that contained lead- and antimony-bearing minerals, presumably galena and stibnite. The area was included in a soil geochemical survey conducted by BHP in 1990 and was anomalous in arsenic and gold. Drilling and trenching in 1992 by Newmont Mining Company identified replacement masses of tabular albite almost pegmatoid in appearance. These masses contained arsenopyrite and assayed as much as 0.25 ounce of gold per ton in zones as much as 5 feet thick. The masses appear to be podiform, and continuity was not demonstrated. They resemble the albitic replacement deposits at Alpha Ridge (NM171), Goodluck Gulch (NM202), and the Walsh Cut (NM214) at Rock Creek. Country rock in the area south of Banner Peak is mainly graphitic schist and quartzite (Bundtzen and others, 1994).
