Dave's Vein

The Dave's Vein is a silver and 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 = Eocene or younger.

Comment (Reference): Primary Reference = Peterson and others, 1982

Comment (Workings): Workings / Exploration = In 1980 Resource Associates of Alaska mapped and sampled the prospect. In 1982 UNC Teton Exploration Drilling Company cut 168 feet of trench, sampled the prospect, and conducted a VLF-EM survey. Twelve trench channel samples assayed as much as 0.17 ppm gold and 4.2 ppm silver over a 120-foot zone. Thirteen grab samples assayed as much as 1.8 ppm gold and 210 ppm silver.

Comment (Deposit): Model Name = Epithermal gold vein

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

Comment (Geology): Geologic Description = This prospect, discovered, mapped, and sampled in 1980 by Resource Associates of Alaska, consists of a 6-foot-wide, northeast-striking, iron-stained quartz vein in argillized, silicified, and pyritized andesite. The andesite is part of the late Eocene to early Oligocene Popof volcanic rocks (Wilson and others, 1995). The vein is exposed for 200 feet along strike and is associated with a knob of silicified andesite. It may merge with the Altair vein (PM091) farther inland. In 1982 UNC Teton Exploration Drilling Company conducted a VLF-EM survey, and trenched and sampled the prospect. Ranges of metal values from trench channel samples are as follows: 0.025 to 0.17 ppm gold, 0.5 to 4.2 ppm silver, 4 to 24 ppm copper, 5 to 36 ppm lead, 1 to 20 ppm zinc, 16 to 152 ppm arsenic, and 0.06 to 0.6 ppm mercury (Peterson and others, 1982).

Comment (Exploration): Status = Inactive
