The Rocky deposit is located on the south slopes of Mount Franklin, about 3.5 kilometres north of Youbou. The Rocky workings have not been located, but are believed to be in the vicinity of the Osirus A claim.

The area is underlain by rocks of the Early to Middle Jurassic Island Plutonic Suite which intrude Upper Devonian McLaughlin Ridge Formation (Sicker Group) mafic volcanics and Mississippian to Pennsylvanian Fourth Lake Formation (Buttle Lake Group) ribbon cherts and crinoidal limestone. A major anticline occurs to the east of the property and the area is highly faulted.

Rhodonite and jasper occur in lenticular masses in cherts and cherty tuffs of the Lower Mississippian Shaw Creek Member (dated by conodonts, Personal Communication - Nick Massey, 1991) with associated rhodocrosite and spessartine. Disseminated pyrite and chalcopyrite occur in quartz veins associated with diorite. Rhodonite development is restricted to areas of very dark ribbon chert which may be cut by major faults. Chert occurs in the general vicinity of Island Plutonic Suite intrusives and major faults. The main rhodonite pod is adjacent to a fault.

The main showing on the Osirus A claim is good quality, deep pink rhodonite which compares favourably with Hill 60 (092B 027) rhodonite. Lower quality rhodonite also occurs in the area. Rhodonite locally occurs in bands 2 to 5 millimetres wide and in crackle breccia veinlets and lenses. A faint pink colouration was noted in wider alteration zones. The main zone strikes 149 degrees and dips 30 degrees east over a 1 metre square area. The zone is capped by intense maganese oxide staining.

Surface stripping was done on the Rocky claim in 1977 and 1978; 555 kilograms of rhodonite were produced (Exploration in British Columbia 1977, 1978). The quantity of gem quality rhodonite on the Osirus A claim is low. From 1985 through 1989, BHP-Utah Mines completed programs of geochemical sampling, geological mapping and ground and airborne geophysical surveys on the area as the Stiker Property. In 1988, Osirus Enterprises completed a program of prospecting on the Osirus A claim.
