Capsule Geology

The Arc showing is located on an unnamed tributary of Lehto Creek.

The area is underlain by marine sedimentary and volcanic rocks of the Upper Triassic Stuhini Group. Rocks in the Arc vicinity is underlain by andesite, tuffs and minor sedimentary rocks. The volcanics and sediments are indurate and silicified with sericite-chlorite-clay secondary mineral assemblages. The older volcanics and sediment roof pendant is engulfed by the Lehto batholith felsic to intermediate intrusives.

Locally, several zones containing pyrite and chalcopyrite mineralization in narrow quartz-carbonate veins are exposed at 50 metre intervals over a distance of 200 metres. The veins strike 060, dip vertically, and range between 1 and 5 centimetres in width over a strike length of 1 to 3 metres.

In 1989 high-grade gold mineralized float was discovered in moraine at the toe of a glacier located on the southern half of the Arc 10 claim. Re-sampling of pyrite rich quartz float boulders from the moraine assayed up to 28.56 grams per tonne gold (Assessment Report 21067). Grid soil sampling has outlined a linear geochemical gold anomaly trending 115 degrees that is 800 metres in length and borders the south edge of the glacier from which the anomalous float is believed to have been transported from.

In 1990, Noranda Mining and Exploration Inc collected 147 rock, 16 silt and 308 soil samples on the Arc 10-12 claims group (Assessment Report 21067). They also conducted 6.8 kilometres of ground magnetic surveying. No prior work was documented in the claim area.

In 2006 and 2007, Hathor Exploration Ltd. completed a 7228.7 line-kilometre airborne geophysical survey on the area as the Jack and Snip claims of the Iskut project. In 2008, Max Minerals Ltd. examined the property.
