Geologic information

Identification information

Deposit ID 10003215
MRDS ID A016026
Record type Site
Current site name Unnamed (on Alder Creek)

Geographic coordinates

Geographic coordinates: -166.19334, 65.06234 (WGS84)
Relative position Alder Creek is an east tributary to Gold Run who's mouth is 1.9 miles upstream of the confluence of Gold Run and Bluestone River. This lode prospect is located on the south side of the creek, at approximately 320 feet surface elevation, 1,000 feet southeast of the confluence with Gold Run. This prospect is just southeast of the facilities of Sullivan's Camp and it is shown as a prospect occurrence on the USGS 1:63,360 topographic map of the Teller A-3 quadrangle. It is locality 21 of Cobb and Sainsbury (1972). Cobb (1975) summarized relevant references under the name 'Alder Cr.'.

Comments on the geologic information

  • Geologic Description = This is a lode prospect initially exposed on lower Alder Creek by placer operations and subsequently explored to a depth of 60 feet from exposures on the south side of the creek. The prospect is an altered fault (?) zone, in one place 16 feet wide, along a contact between schistose carbonate rocks in the hanging wall and metapelitic rocks in the footwall (Collier and others, 1908, p. 279-280). The altered zone is a talcose material with quartz stringers and blebs, pyrite, and fine gold. A sample assayed 0.06 opt gold and a trace of silver (Collier and others, 1908).??
  • Age = Not known; apparently post-dates regional deformation and metamorphism which is Late Jurassic/Early Cretaceous in age.
