Location and accuracy There was mining on California Creek near the mouth of Jim Pup, about 3.8 miles south-southwest of the north end of Bob Johnson Lake (formerly Big Lake). The mining was in the north half of section 35, T. 31 N., R. 9 W.

Geologic setting

Geologic description

Maddren (1913) reported shovel-and-sluice mining from 1901 to 1909 on California Creek near the mouth of Jim Pup. From 1915 to 1931, a miner sank 18, 18-foot shafts, drove two inclines on a deep channel, and produced a small amount of gold. The records are incomplete but 102 ounces of gold were produced from California Creek from 1901 to 1919. Claims were held during the 1940s and 1950s, and from 1980 to 1986. There was mining in 1985 (Dillon (1987); in 1990 (Swainbank and others, 1991); and from 1999 to at least 2000, when the ground was being worked with a suction dredge and a backhoe (Kurtak and others, 2002). High benches are present but apparently were not mined. (Also see the placers on nearby Jim Pup (CH024) and Wakeup Creek (CH025) which are geologically similar and may be contiguous.)

Production and reserves

Workings or exploration Maddren (1913) reported shovel-and-sluice mining from 1901 to 1909 on California Creek near the mouth of Jim Pup. From 1915 to 1931, a miner sank 18, 18-foot shafts, drove two inclines on a deep channel, and produced a small amount of gold. The records are incomplete but 102 ounces of gold were produced from California Creek from 1901 to 1919. Claims were held during the 1940s and 1950s, and from 1980 to 1986.

Indication of production Yes; small
Reserve estimates Apparently none.
Production notes The records are incomplete but 102 ounces of gold were produced from California Creek from 1901 to 1919. Mining continued to 1931, and again in 1985, in 1990, and from 1999 to at least 2000, but there is no record of the amount of gold that was produced.
