Crown Point; Comstock Prospect, Fairbanks District, Fairbanks North Star Borough, Alaska, USA

Latitude: 64°51'28"N
Longitude: 147°59'56"W
Location: The Crown Point prospect is located in the SE1/4NW1/4 sec. 5, T. 1 S., R. 2 W., Fairbanks Meridian. The prospect is on the east slope of Eva Creek, about three-quarters of a mile north of Ester Creek and about 0.9 mile northeast of the town of Ester. The mine is included in locality 19 of CObb (1972 [MF 410]).
Geology: An inclined shaft was driven 20 feet along two narrow quartz veins that were parallel to joints in schist (Chapin, 1914 [B 592-J, p. 353]). The two veins, 2 inches and 0.5 inch thick, respectively, are oriented N. 40 W., dip 65 SW., and are separated by 4 feet of chloritic schist. The adjoining schist is altered to clay. Specks of visible gold were found in the quartz and the wall rock was said to contain a little gold (Chapin, 1914 [B 592-J, p. 353]).
Workings: Two thin gold-quartz veins were explored by a 20-foot inclined shaft (Chapin, 1914 [B 592-J, p. 353]).
Alteration: The schist next to the veins has been altered to clay.
Production: There is no information available on production.
