Capsule Geology

The Nic North Skarn occurrence is located at an elevation of approximately 393 metres on a southwest-facing slope in the northeastern headwaters of the Klaskish River.

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.

Locally, a 3- by 1.5-metre outcrop along road cut exposes very fine grained greenish grey volcanic rock displaying pervasive, patchy silicification; increased chlorite and epidote along fractures; abundant epidote-chlorite±actinolite stringers; fracture-controlled and disseminated pyrite and lesser chalcopyrite in an approximately 20 centimetre wide epidote- and chlorite- rich zone with up to 10-centimetre-wide patches of red pyrope garnet.

Work History

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. The area has been previously explored in conjunction with the Tent (MINFILE 092L 266) occurrence. A grab sample (17434) yielded 0.792 gram per tonne gold, 11.8 grams per tonne silver, 3.94 per cent copper and 21.9 per cent iron (Assessment Report 31915).

In 2019, First Geolas Consulting completed a minor program of prospecting and rock sampling on the area as the Nic property. A rock sample (Y993851) assayed 1.49 per cent copper and 0.414 gram per tonne gold (Assessment Report 38879).
