Location and accuracy Wakeup Creek is a tributary of Jim Pup. It is about 2.4 miles south of the north end of Bob Johnson Lake (formerly Big Lake). The creek has been mined for about 1,500 feet above its mouth, through the east half of section 26, T. 31 N., R. 9 W.

Geologic setting

Geologic description

Although gold was discovered near Wakeup Creek on California Creek (CH023) and Jim Pup (CH024) by 1901, the first reported gold production on Wakeup Creek was in 1926 (Kurtak and others, 2002). Drift mining continued most years until 1941 and a total of 1,795 ounces of gold was produced from 1926 to 1941. Shafts were sunk in 1948 and 1949 and there were active claims at various times until at least 1997.
There are three types of placers on Wakeup Creek: 1) in the modern channel, 2) in a deep channel, and 3) in a high channel. The modern channel rests on older gravel, i.e., it does not go down to bedrock. The early mining was along the modern channel but most of the original shallow gravel has been covered by tailings from later mining. The deep channel, which was the most productive, was drift mined for about 1,500 feet upstream from the mouth of Wakeup Creek. It is probably the continuation of the deep channel on Jim Pup (CH024). Bedrock is about 55 feet deep at the mouth of the creek and deepens to 112 feet upstream. The deep channel is incised into hard, smooth, schist bedrock with five or six gutters, 2 to 4 feet deep, along its bottom The channel is about 25 feet wide at its lower end and narrows upstream to 15 to 20 feet. The gold is generally on the high points of the bedrock between the gutters, but in places is also distributed throughout the gravel. The gold is fine but rough with only a few larger pieces. The ground ran from $3.50 to $4.00 in gold per square foot of bedrock (at $35 per ounce of gold). The high channel appears to be a continuation of a channel on Jim Pup Creek (CH024) that drained into Bob Johnson Lake. The gravel in the high channel was about 20 feet deep when it was explored in 1937. There is no record of gold being produced from the high channel but it was said to run about $0.50 in gold (at $35 per ounce of gold) per square foot of bedrock (Reed, 1938). Kurtak and others (2002) suggest that most of the deep channel has been mined out and that the high channel has low gold values. (Also see the placer on nearby California Creek (CH023) which is geological similar and may be contiguous.)

Production and reserves

Workings or exploration Although gold was discovered near Wakeup Creek on California Creek (CH023) and Jim Pup (CH024) by 1901, the first reported gold production on Wakeup Creek was in 1926 (Kurtak and others, 2002). Drift mining continued most years until 1941. Shafts were sunk in 1948 and 1949 and there were active claims at various times until at least 1997.
Indication of production Yes; small
Reserve estimates Probably none.
Production notes Based on incomplete records, 1,795 ounces of gold were produced from Wakeup Creek from 1926 to 1941, mostly by drift mining. There was activity on the creek from 1948 to 1997 and some gold may have been recovered in during exploration.
