Nelson Gulch

The Nelson Gulch is a tungsten 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 (Workings): Workings / Exploration = The area was explored for scheelite and other strategic minerals during World War II. The lodes were apparently not mined, but attempts were made to recover scheelite from the placers in this area.

Comment (Deposit): Model Name = Low-sulfide, scheelite-bearing quartz vein with some gold.

Comment (Geology): Geologic Description = The Nelson Gulch prospect is a scheelite-bearing quartz vein or veins. On the basis of the size of abundant float in the area, the scheelite-bearing vein is as much as 1.5 feet wide (Coats, 1944, p. 4-6). Albite and some gold also occur with the scheelite. The Nelson Gulch prospect is the southernmost of several scheelite occurences between this locality and the Christian Creek prospect (NM075), 1.6 miles to the north. The rocks in the area consist of interlayered marble and metasedimentary schist (Hummel, 1962 [MF 248]). A prominent marble layer apparently underlies the scheelite-bearing vein. The schistosity and layering strike northerly and dip at shallow angles to the east.

Comment (Geology): Age = Probably mid-Cretaceous or younger; post-dates regional metamorphism.

Comment (Exploration): Status = Inactive

Comment (Reference): Primary Reference = Coats, 1944
