The Whitehorse Copper Belt is located west of Whitehorse and contains 30+ mines, deposits and showings. By 1900, most of the important deposits had been discovered and the first small ore shipment was made that year. Many of the occurrences in the Copper Belt are skarns. The skarns form on or near the contact between the Whitehorse batholith and the Lewes River group. The Whitehorse batholith is commonly a grey coarse-grained hornblende granite and ranges from quartz monzonite to granodiorite to diorite. The Lewes River group contains numerous different rock types, most importantly of which is the limestone group, which is essential in the formation of skarns in the area.  A small number of occurrences within the Copper Belt are vein and/or replacement and occur within the Whitehorse batholith granite.

The Kodiak Cub deposit is hosted in interbedded dolomite underlain by pyritic siltstone and crosscut by basaltic dykes. Mineralization consists dominantly of bornite and magnetite with lesser chalcopyrite (Open File 1984-1). Ore calculations in 1971 (not NI 43-101 compliant) determined the deposit contains 57,000 tonnes of Cu grading 1.17% (Open File 1984-1).

Diamond drilling in 1987 intersected magnetite-serpentine-bornite skarn with grades of 2.9% Cu, 0.13 oz/ton Au, and 0.62 oz/ton Ag over 15.2 feet (AR 091718).
