Comments on the geologic information

  • Geologic Description = The John Bull Hill mine is an area of extensive, hillside placers along the right bank of Candle Creek near the mouth. Data from 53 drill holes showed 15 to 60 feet of ice and muck, 0 to 18 feet of barren gravel, 0 to 25 feet of auriferous gravel, 1 to 29 feet total gravel and 0 to 13 feet of auriferous bedrock. Averages of the drillhole data are: 35.0 feet ice and muck, 4.2 feet barren gravel, 6.7 feet auriferous gravel and 3.1 feet auriferous bedrock. Three of the holes bottomed in limestone bedrock and the others bottomed in decomposed schist (Henshaw, 1909). All ground is frozen. A gold nugget worth $62.10 (Au at $20.67 per ounce) was found. Concentrates contain abundant pyrite, hematite, rutile, occasional garnet, and little magnetite.
  • Age = Quaternary.

Comments on the reserve resource information

  • Reserves = Arctic Circle Enterprises estimated gold reserves on John Bull Hill to be 8,500 ounces in 1952 (Williams, 1998).

Comments on the workings information

  • Workings / Exploration = The placer has been mined since the early 1900's. Exploration was by drifting and drilling. Mining through the 1950's was mainly by hydraulic methods. All the ground in the area is frozen and requires stripping and thawing prior to mining. Since the 1980's the area has been open-cut mined by front end loaders.
