The TH zone is located on the east side of Steele Creek, at an elevation of approximately 370 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 255, 092L 134, 092L 164 and 092L 337).
Locally, a 11 metre wide garnet-epidote skarn zone hosts massive chalcopyrite in bands and as pods, up to 25 centimetres in width, and minor magnetite.
In 2007, a rock sample (RK 0707) assayed 16.68 per cent copper and 0.078 per cent zinc; while float samples from the same area yielded up to 23.7 per cent copper, 0.11 per cent zinc and 68.8 grams per tonne silver (Assessment Report 30021).
In 2013, two chip samples (GT-1 and GT-3) of epidote skarn hosting disseminated to massive chalcopyrite±bornite±molybdenite exposed in outcrop along the creek assayed 7.56 and 23.8 per cent copper, 0.552 and trace molybdenum with 40 and 102 grams per tonne silver over 2.00 and 0.25 metres, respectively (Assessment Report 34322).
In 2018, three rock samples (TH1 through TH3) from the south side of the creek yielded from 0.755 to 11.2 per cent copper with up to 0.549 per cent molybdenum and 80.3 grams per tonne silver (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 1977 five diamond drill holes, totalling 712 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.
