Capsule Geology

The area between the Craig and Iskut Rivers is underlain by metamorphosed Paleozoic (Permian and older) rocks of the Stikine Assemblage. These rocks are unconformably overlain by stratified Triassic rocks. This area lies on the eastern margin of the Tertiary-Cretaceous Coast Plutonic Complex.

In 1988, the Phiz vein was located on the Rob 13 claim. Stripping and trenching exposed the vein over a 24.4-metre strike length and where exposed the vein averages about 3.0 metres in width. It contains chalcopyrite, galena, pyrite, chalcocite(?) and malachite/azurite. High grade zones within the vein contain up to 50 per cent sulphides.

Surface channel samples assayed 49.7 grams per tonne gold and 135.8 grams per tonne silver over 3.2 metres, 88.0 grams per tonne gold and 87.1 grams per tonne silver across 2.98 metres, and 16.9 grams per tonne gold with 44.6 grams per tonne silver across 7.0 metres (George Cross Newsletter November 18, 1988). Fifteen holes have been drilled in the vicinity of the vein. Several quartz pebbles were found in the casing indicating that the vein could be very shallow in depth. Holes 7,9,10 and 11 encountered a broad silicified zone with disseminated galena, sphalerite and chalcopyrite mineralization. The zone appears to have a width of up to 12 metres. Drilling about 46 metres to the southeast of the vein intersected a mineralized quartz vein which hosts disseminated galena and pyrite.

In 1988, a well mineralized quartz vein structure (the Phiz vein) was located in the north-central portion of the Rob 13 claim by Crest Resources Ltd and Magenta Development Corp. During September 1988, a total 663 soil samples were collected. This area underwent extensive blasting and trenching, which was then followed by a short diamond drill program. A total of 68 rock chip samples were collected from the Phiz showing area. Fifteen diamond drill holes (BQ) were drilled on the Phiz showing totalling 950 metres (Assessment Report 18512). Previous preliminary field work in 1987 consisted of prospecting and soil sampling.

In 1991, Crest Resources, Magenta Development and Adrian Resource conducted a 105 kilometre airborne electromagnetic and magnetic survey.

Please refer to Rock and Roll (104B 377) for details of work done in 2004 by Conquest Resources Limited and Newcastle Minerals Ltd. who formed a joint venture to work on both properties, focusing on the area between the two occurrences.

During 2009 through 2011, Skyline Gold Corp. completed programs of prospecting, geochemical (rock and soil) sampling, trenching, airborne and ground geophysical surveys and 23 diamond drill holes, totalling 5676 metres, on the area as the Iskut property.
