The Bob 12 (Zone C) occurrence is located on the east side of Steele Creek, at an elevation of approximately 500 metres.
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.
Mineralization in the area occurs intermittently over 2.5 kilometres along the northwest striking hornblend-quartz diorite contact (the Bonanza mine (MINFILE 092L 164), and the Bob 21 (MINFILE 092L 134) and Bob 17 (MINFILE 092L 337) occurrences). The occurrence consists of pods of garnet skarn plus or minus epidote, pyroxene, actinolite, quartz, chlorite and calcite, with magnetite, chalcopyrite, pyrite, gold and silver.
The C (Cliff) zone skarn is developed on a limestone-volcanic contact and is up to 5.5 metres wide. It consists of roughly banded zones of clear to yellow garnet and magnetite with only minor chalcopyrite. Twenty metres south of this zone, a 1 metre band of massive chalcopyrite with magnetite, trending at 100 degrees and dipping 80 degrees south, is developed in a hornfelsed volcanic inclusion in the quartz diorite. Five metres north of the main skarn zone, a 0.8 metre volcanic inter-bed in the recrystallized limestone defines a broad fold nose plunging at 20 degrees towards 128 degrees. A 0.3 metre horizon of massive magnetite with up to 5 per cent chalcopyrite is developed on the footwall of the volcanic inter-bed.
In 1994, a chip sample (GD111505) of volcanic rock with trace mineralization assayed 3.02 grams per tonne gold and 0.266 per cent copper; while a chip sample (GD111606) of magnetite-chalcopyrite assayed 5.68 grams per tonne gold and 2.23 per cent copper (Assessment Report 23551).
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 and ground geophysical surveys 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.
