Three stratigraphic assemblages have been mapped in the area: (1) Upper Palaeozoic sediments and volcanics of the Stikine Assemblage, (2) clastic sediments of the Triassic Stuhini Group, and (3) Lower Jurassic sediments and volcanics of the Hazelton Group. Four plutonic suites intrude the above: (1) Late Triassic calc-alkaline intrusions coeval with Stuhini Group stratigraphy, (2) Jurassic Copper Mtn, (3) Jurassic Texas Creek and (4) Tertiary Coast Plutonic suite.

Cliff showing samples assayed up to 8.0 grams per tonne gold with most other anomalous values in the 50 to 700 parts per billion gold range (Assessment Report 29673). The host rock is rhyolite that has been locally silicified, weakly brecciated and veined with quartz veinlets up to one centimetre wide but generally much less than this value. Galena and pyrite with minor sphalerite and chalcopyrite occurs as veinlets with quartz and as disseminations near these veinlets. The rhyolite is overlain by unaltered argillite except along High Gold Creek and its tributaries where clay altered sedimentary rocks with local biotite hornfels is exposed. This alteration is probably related to a small diorite plug along the northern claim boundary near High Gold Creek.

A linear pattern of highly anomalous gold, lead, silver and zinc in mobile metal ion (MMI) soil samples overlies the rhyolite over a one kilometre length. The anomalous soil pattern occurs over a west-facing slope, with a pronounced northwest linear at the base. A Kuroko style VMS target is indicated in the area of the Cliff showings where rhyolite containing footwall style mineralization is greater than 100 metres thick and is overlain by unaltered argillite. The area has been mapped and MMI soil sampled.
