The Strip occurrence is located east of Kelvin Creek, approximately 8.5 kilometres west of Cobble Hill.

The area is underlain predominantly by bedded chert and cherty basaltic tuffs of the Mississippian to Pennsylvanian Fourth Lake Formation (formerly the Sediment-Sill Unit of Muller), Buttle Lake Group. These are overlain by limestone, bedded chert and cherty tuff of the Upper Pennsylvanian to Lower Permian Mount Mark Formation, Buttle Lake Group (formerly the Buttle Lake Formation). Between the Mount Mark and Fourth Lake formations, and above the Mount Mark Formation, are packages of mainly basaltic rock, of unknown affinity. These Paleozoic rocks are intruded by numerous dykes of feldspar- porphyritic dacite and rhyolite and part of the granodioritic "Koksilah" stock of the Early to Middle Jurassic Island Plutonic Suite (formerly called the Island Intrusions).

On the Strip showing, an 11-metre wide zone of mineralization occurs, apparently at the top of the Mount Mark Formation. The showing consists of semimassive to massive pyrite-magnetite-pyrrhotite- chalcopyrite occurring within a rhyolite intrusion and garnet- epidote-chlorite skarn at the contact zone between Mount Mark chert and the overlying basaltic flows. Limestone is reported at this locality also.

In 1983 through 1985, Reward Resources completed programs of prospecting, geochemical sampling and ground geophysical surveys on the Independence, Koksilah, Pacific Star and Western mineral claims. A 1.1-metre sample assayed 2.34 per cent copper and 6.2 grams per tonne silver (Assessment Report 13997). In 1986, Hollycroft and Nexus resources completed a program of geological mapping and rock sampling on the Sil claims.
