The White Fang (Zone E) occurrence is located on the former Bob 4 claim, located southeast 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 volcanic rocks have been intruded by the Jurassic Nimpkish batholith, which is part of the Early to Middle Jurassic Island Plutonic Suite. Mafic and felsic dikes cut all rock types.

Mineralization in the area occurs intermittently over 2.5 kilometres along the northwest striking hornblende quartz diorite contact (the Bonanza mine (MINFILE 092L 164), and the Bob 21 (MINFILE 092L 134) and Bob 17 (MINFILE 092L 337) occurrences).

Locally, garnet skarn, plus or minus pyroxene, epidote, actinolite, quartz, chlorite and calcite occur over an area of 457 by 76 metres. Finely disseminated chalcopyrite is present within massive garnet and values up to 3.0 per cent copper were reported. Several massive sulphide veins ranging up to 60 centimetres in width are also reported (McDougall, 1961, page 2), but no details are given. A 3 to 63 metre wide body of 80 per cent magnetite containing low copper values, located 100 metres northeast of the White Fang showing is also reported (McDougall, 1961).

In 1976, diamond drilling intersected 30.6 metres of garnet-epidote skarn containing scattered course blebs of chalcopyrite and sections of heavy magnetite over 15.3 metres (Assessment Report 6267).

In 1994, chip sampling yielded up to 0.29 per cent copper over 2 metres (Assessment Report 23551). Diamond drilling, later the same year, encountered 80.5 metre of garnet and garnet-pyroxene skarn with the main copper zone being intercepted for over 16 metres and averaging 0.38 per cent copper and 2.8 grams per tonne silver (DDH 94-2; Assessment Report 24601).

In 2017, six rock samples (J-7 through J-12) taken from the occurrence area yielded from 0.04 to 13.49 per cent copper with 24.09 to 73.71 per cent iron (Assessment Report 37313).

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 1976, three diamond drill holes (Bob 6-8), totalling 294.6 metres, were completed. 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 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. Also at this time, Homegold Resources Ltd. completed an air photo geological interpretation program on the area. In 2015, A.B. Hemingway completed an air 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.
