The Cache showing is located approximately 10 kilometres west of Peachland.
The area is underlain by a dark, biotite-granodiorite of the Middle Jurassic Osprey Lake Intrusions. Descriptions of the site suggest that a number of exposures, trenches and adits exist in this general area and they are collectively grouped under the CACHE showing.
Mineralization appears to be structurally controlled, usually associated with steeply-dipping northeasterly faults. Where mineralized, the granodiorite is altered to a greenish colour due to sericitization. At an upper exposure, northeasterly fractures dip northward in silicified granodiorite that is mineralized with tetrahedrite, pyrite, and chalcocite, the latter probably of secondary origin. Mineralization, which is locally strong, apparently persists for 6 metres northward to a fault which strikes north 80 degrees east and dips steeply to the north. A lower exposure, at 1340 metres elevation, consists of chalcopyrite, pyrite, and specular hematite as disseminations, seams and small masses. These occur mainly in the hangingwall of a fault which strikes north 46 degrees east and dips at 70 degrees northeastward. Sulphide mineralization is usually restricted to within a few feet of the fault. Minor quartz veining is also present.
The earliest evidence of work on the property are two short adits, attributed to prospectors in the 1920s. Small shipments of wire silver were reportedly made at that time. In 1966-67, Koporok Mines Ltd. carried out a program of line-cutting, road-building, claim-surveying, induced polarization surveying, trenching and blasting. In 1969, they had an aerial magnetometer survey flown over the claim area; several magnetic linears and disturbances were identified.
