The Fang or Wilf occurrence is located in the eastern head waters of the Klaskish River, approximately 10 kilometres northeast of the river mouth.

The area lies within the Insular Belt of the Cordillera and is underlain mainly by volcanics, crystalline rocks and minor sediments. Andesitic to rhyodacitic lava, tuff and breccia of the Lower Jurassic Bonanza Group overlie an assemblage consisting of sediments of the Paleozoic Sicker Group and basalts and minor carbonate and clastic sediments of the Upper Triassic Vancouver Group. The Bonanza volcanics are coeval with, or genetically related to, granodiorite stocks of the Jurassic Island Plutonic Suite which intrude all older rocks.

The occurrence lies on the flank of a northwest trending multiphased dioritic pluton of the Island Plutonic Suite that separate Bonanza Group felsic to intermediate volcanics from Karmutsen Formation (Vancouver Group) tholeiitic basalts. The mineralization consists of a 33 metre wide zone of pyrite, chalcopyrite, quartz and epidote in a zone of intense fracturing and silicification of Bonanza andesite flows and interbedded dacite fragmental flow rocks. The zone parallels the intrusive contact and lies 120 metres away from it. Mineralized fractures are oriented at 300 to 325 degrees with a 60-to 85-degree north dip. A second set of mineralized fractures has the same strike, dipping 25 to 40 degrees north. The zone contains 1 to 2 per cent disseminated pyrite. Magnetite occurs at the north and south end.

Mapping in 1990 was reported to indicate that the showing occurs in the contact zone between limy Karmutsen or Bonanza volcanic rocks and granodiorite.

In 1974, a 9.0 metre section was sampled and assayed 0.71 per cent copper. An additional 24 metre section was not sampled but was estimated to contain 0.50 per cent copper (Assessment Report 5129, Figure 7).

Work History

Copper-magnetite mineralization was discovered on the Wilf property by Wilf Tremblay in 1960. In 1962, Riocanex optioned the property and others nearby. They carried out geological mapping, trenching and surface sampling in 1963. In 1964, they drilled two shallow holes near a well-mineralized trench (Assessment Report 21966, page 3). Riocanex also carried out mapping, geochemical surveys and self-potential surveys on the Iron Cop (92L 330) occurrence during this period. They trenched several occurrences and drilled 3 holes for a total of 161 metres. The property lapsed in 1969 and was restaked by Kaisar. No work was filed by them on the Iron Cop. Vanco restaked a group of claims in the vicinity in 1974. From 1973 to 1983, the Iron Cop was controlled by various individuals that attempted to form companies. In 1984, the Iron Cop was consolidated with several nearby showings and optioned to Brinco Mining. In 1983 and 1984, Brinco carried out geological mapping, geochemical surveys, magnetic surveying and diamond drilling of 7 holes totalling 505 metres. From 1986 to 1989, the Iron Cop property was explored by Jim McDonald who carried out trenching and sampling. Defiant Minerals held an option on the property briefly in 1987. In 1990, several claims were sold to Petra Gem Explorations of Canada Ltd. and several others to Omax Resources. In 1990, Petra Gem carried out a program of re-examining the Brinco core. At the same time Omax carried out magnetic and VLF-EM geophysical surveys and soil sampling on a grid over the Wilf showing area. In 1991, Omax carried out an induced polarization survey (6.7 kilometres), a magnetic survey (3.6 kilometres) and a VLF survey (0.8 kilometres) in the Iron Cop area. In the same year, Omax resampled the Wilf showing trenches. During 2010 through 2012, Compliance Energy completed programs of geological mapping and rock, soil and silt sampling and 470 kilometres of airborne magnetic, electromagnetic and radiometric geophysical surveys on the area as the Nic Property. In 2019, First Geolas Consulting completed a minor program of prospecting and rock sampling on the area as the Nic property.
