Identification information

Deposit ID 10009528
MRDS ID D002569
Record type Site
Current site name Nelson Gulch

Geographic coordinates

Geographic coordinates: -165.17635, 64.76818 (WGS84)
Relative position Nelson Gulch is an unnamed small, west-flowing drainage about one-half mile south of Rocky Mountain Creek. The scheelite occurrence is at an elevation of about 1,450 feet in Nelson Gulch and about 1.4 miles due east of the mouth of Rocky Mountain Creek. The occurrence is locality 14 of Hummel (1962 [MF 248]) and is probably the vein occurrence cited by Coats (1944) as being south of Rocky Mountain Creek. It is included with other nearby tungsten occurrences as locality 20 of Cobb (1975) and is locality 33 of Cobb (1972 [MF 463], 1978 [OFR 78-93]). The prospect is located within about 500 feet of the coordinates.

Comments on the geologic information

  • 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.
  • Age = Probably mid-Cretaceous or younger; post-dates regional metamorphism.

Comments on exploration

  • Status = Inactive

Mining district

District name Nome

Comments on the workings information

  • 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.
