Capsule Geology

The Bob 17 (Zones D) occurrence is located on top of a ridge to the east of Steele Creek, approximately 400 metres northwest of White Fang Lake.

The area is underlain by Upper Triassic Karmutsen Formation (Vancouver Group) skarned limestone that occurs as thin layers or lenses within a sequence of pillow lavas, basalts, breccia and minor tuff.

The occurrences consist of pods of garnet skarn plus or minus epidote, pyroxene, actinolite, quartz, chlorite and calcite, with magnetite, chalcopyrite, pyrite, gold and silver.

At the Zone D skarn a well banded section of garnet-magnetite skarn has been mapped over a strike length of 55 metres. Banding is defined by alternating layers of dark red brown to light green and yellow euhedral crystalline to massive garnet with massive locally euhedral magnetite. The magnetite layers range in thickness from five centimetres to two metres. Chalcopyrite occurs throughout the magnetite as disseminations and up to 2 metre wide massive pods.

McDougall (1961, page 2) estimates that 12608 tonnes averaging 3.0 per cent copper and 30 per cent magnetite are present, containing "about $2.45 per tonne" in gold and silver.

In 1976, drill hole Bob 10 intersected 39.6 metres of garnet-magnetite skarn from 32.7 to 72.3 metres (Assessment Report 6267).

In 1993, a sample (GD1111201) of a massive chalcopyrite pod assayed 5.366 per cent copper and 0.428 grams per tonne gold over 2.5 metres; other grab samples yielded up to 100.4 grams per tonne gold (Assessment Report 23551). In 1994, diamond drilling intercepted a 1.3 metre zone averaging 1.88 per copper and 5.1 grams per tonne silver (Assessment Report 24601).

Work History

In 1966, Cominco completed a program of geological mapping and a ground magnetometer survey on the area as the Bob claims. During 1971 through 1977, Imperial Oil completed programs of line cutting, geological mapping, soil sampling and ground geophysical surveys on the area as part of the Hab and Bob claims. In 1993 and 1994, Braddick Resources completed programs of geochemical sampling, geological mapping, ground geophysical surveys and 2 diamond drill holes on the area as the Bon and Bonz 1-2 claims. In 2005 and 2006, A.B. Hemingway completed programs of prospecting and geochemical sampling. In 2007 and 2008, International Bethlehem Mining optioned the property and completed programs of geological mapping, geochemical sampling and a ground magnetic survey. In 2012, Homegold Resources completed programs of rock and soil sampling and a ground magnetometer survey on the area as the Bonanza River property. In 2013, Jinhua Capital Corp. prospected the Steele Creek property. In 2015, A.B. Hemingway completed a photo geological interpretation program on the property. In 2017, Homegold Resources Ltd. completed a minor program of prospecting and rock sampling on the area as the White Fang property. In 2018, Hawkeye Gold and Diamond Inc. completed a minor program of prospecting and rock sampling on the area as the Bonanza property.
