Location and accuracy According to Eakin (1919), a quartz-sulfide vein is located on a ridge between the Kelsall River (formerly Bear Creek) and Nataga Creek. The approximate location is at an elevation of approximately 1,300 feet in the east-central part of section 1, T. 26 S., R. 54 E. of the Copper River Meridian. It is shown as location 14 by Cobb (1972 [MF-424]) and as location 87 by Berg (1984).

Geologic setting

Geologic description

Eakin (1919) describes the prospect as a vein a few inches wide that contains pyrite, pyrrhotite, chalcopyrite, and sphalerite in quartz gangue. The main portion of the vein is chalcopyrite and pyrrhotite; sphalerite occurs along the vein margins. No additional detail is provided in subsequent references to this prospect (Cobb, 1972 [MF 424]; Cobb, 1978 [OF 78-316]; and Berg, 1984).

Mineral deposit model Very little information, but apparently a polymetallic quartz-sulfide vein (Cox and Singer, 1986; model 22c).
Mineral deposit model number 22c

Production and reserves

Workings or exploration No workings are reported and very little information is available. The cursory description by Eakin (1919) appears to have been replicated in subsequent references. The claim(s) is apparently long inactive.
Indication of production None
