Capsule Geology

The Selly showing, located at Selly Lake, consists of small skarn zones. The zones are developed in rocks of the Devonian to Middle Triassic Boundary Ranges Metamorphic Suite (Stikinia terrane) adjacent to a north trending intrusive contact with Late Cretaceous Coast Plutonic Complex granite and alkali feldspar granites. In general, the Boundary Range metamorphics in this area consist of greenstone and greenschist.

Numerous gossans occur on this property due to disseminated pyrite and pyrrhotite found in the rocks. Near the intrusive contact, zones of carbonatization and small skarns occur. Within these altered zones, minor, finely disseminated, pyrite, pyrrhotite, chalcopyrite and galena were observed. Small quartz veins are also present in the metamorphic rocks adjacent to the intrusion. Minor disseminated sphalerite is present in flow banded rhyolite.

During May 1981, reconnaissance stream sediment sampling was carried out in the Tagish-Bennett Lake areas of northwestern British Columbia. The sampling was undertaken as part of a large regional program known as the Kulta Project. As a results of an anomalous gold sample in a creek draining north into Skelly Lake, the Selly Property was staked. No previous work is recorded concerning the property. Follow-up work in 1981 consisted of the collection of 27 soil -, 12 rock - and 6 stream sediment samples. A series of anomalous soil samples occurred near Skelly Lake just north of the Selly claims. High values in copper, zinc, silver and antimony were encountered. One sample (C249) ran 522 parts per billion gold (Assessment Report 10428). Rock geochemistry failed to isolate the source of the anomalous values.
