Capsule Geology

The Triple Junction showing is located on the west wall of a glacier-filled valley approximately 10.7 kilometres southeast of the confluence of Eskay Creek and Iskut River.

The Triple Junction target was selected from structural research that suggested a point of confluence of three splay faults from the regional Harrymel Fault and located near a point where a mapped thrust fault intersects this fault junction. The showing is primarily within a strongly silicified grey, aphanitic to fine grained sediment, a fine-grained plagioclase porphyry, and lesser amounts in felsic volcanics (aphanitic to fine grained rhyolite).

A 2016 prospecting, rock and soil XRF sampling survey for DeCoors Mining Corp. on the Palm Springs property sampled the Triple Junction area. Six samples returned assays of greater than 10,000 parts per million Zn (Assessment Report 36311).
