The Fox prospect lies approximately 17 kilometres east-southeast of Bralorne on Mount Piebiter, encompassing the headwaters of Tommy, Piebiter and Connel creeks. This region of the Coast Crystalline belt contains the Cretaceous to Tertiary Bendor pluton which intrudes metamorphosed volcanics, sediments and ultramafics of the Mississippian to Jurassic Bridge River Complex (Group). The bedded rocks are predominantly argillaceous to phyllitic, with prominent thinner bedded sections of quartzite or chert, minor limestone lenses and greenstone, which appear to be folded into a broad northwest trending isocline. Plutonic rocks are granodiorite, with possible minor diorite.

Mineralization consists of pyrite, minor chalcopyrite, tetrahedrite and talc in regionally conformable quartz veins, and pyrite, pyrrhotite, trace chalcopyrite and molybdenite in a small granodiorite plug at the headwaters of Piebiter Creek. Quartz veining with tetrahedrite mineralization from a gossanous area near the headwaters of Connel Creek graded up to 17.9 grams per tonne silver and 0.04 per cent lead (Assessment Report 15292). Pyrite and pyrrhotite are also present as disseminations in sedimentary rocks and locally as fracture fillings in granodiorite.

In 1985, D.P. Taylor prospected and sampled the area.

In 2007 and 2008, airborne ZTEM surveys were completed on the area. In 2009, a MMI soil sampling program was completed. In 2011, Worthington Resources Ltd. completed a 408.5 line-kilometre airborne ZTEM survey on the area as the Royalle property.
