Capsule Geology

The Bob 21 (Zone F) occurrence is located at an elevation of approximately 610 metres on a west-facing slope, east of Steele Creek and approximately 1.8 kilometres north of White Fang Lake.

The area is underlain by thin layers or lens of limestone within a sequence of pillow lavas, basalt, breccia and minor tuff of the Upper Triassic Karmutsen Formation (Vancouver Group). Hornblende-quartz-diorite of the Late Jurassic Nimpkish batholith lies about 2.0 kilometres to the west. The Nimpkish batholith is part of the Jurassic Island Plutonic Suite.

Locally, massive magnetite, pyrite and chalcopyrite occur in garnet-epidote-calcite skarn at the contact between limestone and massive basalt over a distance of 60 metres. The zone trends 120 degrees and dips 30 degrees to the southwest. The mineralization has a maximum width of 1 metre.

In 1994, chip samples yielded up to 5.1 per cent copper and 1.67 grams per tonne gold over 1.0 metre width (Assessment Report 23551).

Work History

In 1966, Comcino 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 1 diamond drill hole 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.
