| Location and accuracy | Cobb (1972, MF-413), loc. 88; NW1/4SE1/4 sec. 19, T. 3 N., R. 2 E., of the Fairbanks Meridian. The coordinates given are for the approximate center of placer-mined ground that extends for about a mile from the head to the mouth of Chatham Creek. |
Geologic descriptionBedrock is quartz muscovite schist, quartzite, and chlorite quartzose schist (Newberry and others, 1996). Gold has been found in stream placers from the head to the mouth of the creek. Stibnite has been found in places as veins a foot or more thick, parallel to the structure in the schist (Prindle, 1906, p. 114). Scheelite has been found in concentrates (Byers, 1957, p. 188, 210), along with cassiterite (Joesting, 1942; ATDM Pamph. 1, p. 10-11). Considerable stibnite float was found in old dredge tailings (Joesting, 1943, p. 9).
Mining was largely by open-cut methods in most years from 1903 to 1915. A dredge operated from 1926 or 1927 through 1934 (Cobb, 1976, p. 29). Gold production from 1903 to 1910 was over 17,700 ounces (Prindle and Katz, 1913, p. 112-113). Mining has continued intermittently to as recently as 1997 (A. Miscovich, oral communication, 1998). | |
