Relative position Elkhorn Creek is a southwest tributary to the Niukluk River. The mouth of Elkhorn Creek is 0.5 miles upstream of the mouth of Camp Creek (SO057), which is about 9 miles upriver from Council. About the lower mile, between elevations of 125 and 200 feet, have been placer mined. This is locality 114 of Cobb (1972, MF 445; 1978, OF 78-181).

Comments on the geologic information

  • Geologic Description = Placer mining has taken place for about a mile along the lower part of Elkhorn Creek. The drainage is incised into a terrace along the Niukluk River. Creek gravels were 2.5 feet thick near the mouth and bench deposit at the mouth consisted of 4 feet of cross-bedded sand and gravel that are overlain by 6 feet of clay, muck, and vegetation. The paystreak was apparently spotty but some coarse gold was recovered; one nugget was worth $55 (about 2.75 ounces). Quartz was commonly attached to the coarser gold and one nugget was embedded in schist (Brooks and others, 1901). Bedrock in the area is probably part of a lower Paleozoic metasedimentary assemblage (Till and others, 1986).
  • Age = Quaternary.

Comments on the production information

  • Production Notes = Production was $30,000 (about 1,450 ounces) in 1900 (Brooks and others, 1901) and totaled about $120,000 (about 6,000 ounces) by 1906 (Collier and others, 1908). Total production is probably more than 10,000 ounces (Cobb, 1978, OF 78-181).

Comments on the workings information

  • Workings / Exploration = Small-scale surface mining took place before WW I and a dredge operated between 1914 and 1918 (Cobb, 1978, OF 78-181). The lower mile of the creek has probably been extensively worked.
