At the Red zone area of the Tide property, andesitic rock of the Lower Jurassic Unuk River Formation are unconformably overlain by Lower Middle and Middle Jurassic rocks from the Betty Creek, Mount Dilworth and Salmon River Formations, respectively, all of the Hazelton Group. The Texas Creek Plutonic Suite comprises a group of Early Jurassic granodioritic stocks, dikes, sills and a batholith in the area.

In 1990 it was reported that two types of mineralization occur in the veins at the Red zone and these are: 1. arsenopyrite and 2. chalcopyrite-pyrrhotite. The veins are traceable for about 20 meters. Thin pyrrhotite-chalcopyrite (trace galena) veinlets were observed occasionally (Assessment Report 11528).

In 1995, mapping indicated arsenopyrite and pyrite and sphalerite and quartz occurred in a strong shear and gossanous zone in an area of andesitic lapilli tuff. A 0.5 metre chip assayed 10.46 grams per tonne gold and 63.8 grams per tonne silver (Sample 11209, Drawing 5, Assessment Report 24190).
