The Joy 84 occurrence area is located 9.75 kilometres east-northeast of Mount Sister Mary and 7.3 kilometres north of the Stikine River, about 57 kilometres east-northeast of the village of Iskut. Rugged mountains to the north of the property and deeply incised rolling highlands to the south marks the division between the Cassiar Mountains and Spatsizi Plateau.

The area lies within the Stikine arch which is bounded to the south by the Bowser Basin. The general east orientation of bedding, folding and faulting found along the Stikine arch contrasts with the dominant northwest trend of lithological units within the Stikine Terrane. Mapping by the Geological Survey of Canada (Open File 2241) defines the underlying lithology as island arc-related volcanics and sediments of Upper Triassic to Middle Jurassic age, which were deposited in the Hazelton eugeosynclinal trough. Extensive plutonism from the Late Triassic to the Late Jurassic emplaced dioritic, monzodioritic, granodioritic and granitic phases of the Hotailuh batholith. These units have been deformed by regional lower greenschist metamorphism and folding during the Lower Jurassic and open folding during the Upper Jurassic.

The Joy 84 prospect comprises a 75 metre wide, north-northwest striking mineralized fracture zone hosted by unnamed Upper Triassic to Lower Jurassic massive porphyritic and amygdaloidal andesite. The length of the zone is unknown, however, the Sec 5 showing (104H 028), 900 metres to the south-southeast, may lay on strike. Chalcocite, as fissure fillings, is accompanied by alteration masses of epidote, pinkish zeolite and aragonite. Malachite is common on weathered surfaces.

Approximately 1.2 kilometres of bulldozer trenching (part of a larger 5.5 kilometre survey) tested the prospect. A rock chip sample from a 0.6 by 3.0 metre panel assayed 0.21 per cent copper (Property File - Bowser Resources Ltd., 1969).

In 2008, about 350 metres southwest of the main showing, a select rock sample from quartz stockwork with malachite, trace tetrahedrite and minor native copper assayed 0.21 per cent copper and 2.6 grams per tonne silver. Another sample from maroon dacite with minor silicification and occasional epidote assayed 0.14 per cent copper and 0.7 gram per tonne silver (Assessment Report 30783).

Copper mineralization in the McBride River area was first noted by Gabrielse during the course of mapping for the Geological Survey of Canada (Open File 1005). Extensive staking, geological mapping, airborne magnetic surveying, bulldozer trenching and minor soil and lithogeochemical sampling has been conducted over the prospect and adjoining ground from 1969 to 1971.

In 2008, a program of prospecting was carried out on the Sky claim held by D. McInnis.
