Mount Goldie

The Mount Goldie is a lead, niobium (columbium), chromium, copper, cobalt, beryllium, arsenic, tin, gold, and zinc 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 (Commodity): Ore Material = other unidentified minerals.

Comment (Geology): Age = Tertiary; mineralization is interpreted to be linked to the Kahiltna pluton (Tmk), part of the McKinley Sequence, that has been determined to range from 52.3 to 56.2 m.y. in age by K/Ar method (Reed and Lanphere, 1972; Reed and Nelson, 1980).

Comment (Exploration): Status = Inactive

Comment (Workings): Workings / Exploration = Reconnaissance mapping, stream silt and rock sampling are all that have been done here. Two stream sediment samples from drainages in this area contained 0.2 and 0.3 ppm gold, respectively (Clark and Hawley,1968).

Comment (Reference): Primary Reference = Clark and Hawley, 1968

Comment (Geology): Geologic Description = Clark and Hawley (1968) describe the Mount Goldie silt anomaly as underlain by Mesozoic graywacke, quartzite and argillite (KJs) that are cut by Tertiary(?) aplite dikes and auriferous quartz veins. One rusty-weathering dike, about 3 feet wide, contains pyrite and arsenopyrite with minor gold. The aplite dikes may be related to the early Tertiary Kahiltna pluton (Tmk, Reed and Nelson, 1980) about four miles to the northwest. Two stream silt samples from streams draining this area contained 0.2 and 0.3 ppm gold, respectively (Clark and Hawley, 1968, Figure 2, no. 56). ? Stream sediment samples with elevated Au, As, Be, Co, Cu, Cr, Nb, Pb, Sn, and Zn values from four streams in the area between the Tokositna and Kahiltna Glaciers indicate the area is auriferous and could host mineralized prospects (Clark and Hawley, 1968). See Rocky Cummins (TL016).

Comment (Deposit): Model Name = Possibly low-sulfide Au-quartz veins (Cox and Singer, 1986; model 36a).

Comment (Deposit): Other Comments = the area lies within Denali National Park and Preserve.

Comment (Commodity): Ore Material = other unidentified minerals

Comment (Geology): Age = Chron age is for McKinley Sequence.
