The Bob 11 (Zone B) occurrence is located on the east side of Steele Creek, at an elevation of approximately 400 metres.
The area is underlain by skarned limestone that occurs as thin layers or lenses within a sequence of pillow lavas, basalt, breccia and minor tuff of the Upper Triassic Karmutsen Formation (Vancouver Group). The volcanic rocks have been intruded by the Late Jurassic Nimpkish batholith, which is part of the Jurassic Island Plutonic Suite. Mafic and felsic dikes cut all rock types.
Mineralization occurs intermittently over 2.5 kilometres along the northwest striking hornblende-quartz diorite contact (see also MINFILES 092L 164, 092L 255, 092L 134 and 092L 337).
Locally, a garnet skarn horizon has developed entirely within the Karmutsen Formation volcanics. The zone trends at 150 degrees, dips 45 degrees to the southwest and is up to 2 metres wide, with magnetite and associated chalcopyrite mineralization concentrated in a rough 1 metre band along the footwall. Above the magnetite-chalcopyrite zone the dark, red -brown garnet skarn is obliquely cross-cut by a 5 to 10 centimetre zone of strong epidote alteration. The epidote alteration hosts massive chalcopyrite, minor magnetite and 1 to 2 per cent molybdenite.
In 1973, diamond drilling intersected 3.9 metres, from 9.45 to 13.35 metres depth, of garnetite skarn with heavy pyrite and chalcopyrite sections (Assessment Report 5394). In 1974, diamond drilling intercepted 1.15 per cent copper over 3.9 in DDH 74-2 and 2.64 per cent copper over 3.15 metres in DDH 74-3 (Assessment Report 23551).
In 1994, a grab sample (GD1111602) assayed 8.26 per cent copper, 0.239 per cent molybdenum, 27.2 grams per tonne silver and 0.15 gram per tonne gold (Assessment Report 23551).
In 2018, four rock samples (B1 through B4) of angular float from the base of a cliff near the Zone B occurrence yielded from 0.078 to 4.38 per cent copper and up to 16.3 grams per tonne silver and greater than 50 per cent iron (Assessment Report 38244).
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 1973 and 1974, three diamond drill holes, totalling 171 metres, were completed. 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.
