Comments on the geologic information

  • Geologic Description = Prospecting in 1922 yielded two grains of coarse gold at the bottom of a 30-foot-deep prospect shaft (Reed, 1938). Additional prospecting in 1932 yielded one grain of gold (said to be worth $0.05) from a 4-foot open cut near where the stream valley opens into the valley of Lake Creek. No other data are available for this occurrence.
  • Age = Quaternary.

Mining district

District name Koyukuk

Comments on the workings information

  • Workings / Exploration = Last Chance Creek was prospected by at least three shafts to bedrock and an open cut. A 30-foot shaft was sunk in 1922 and 15-foot and 35-foot shafts were sunk in 1932. The 15-foot shaft reportedly was near the mouth of the creek and the 35-foot shaft was farther upstream 'at the forks'. Claims have been staked on Last Chance Creek since 1969, but there are no reports of any work.
