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 Cowley Park deposit is a skarn zone located within an easterly trending band of limestone surrounded by hornblende granite. The limestone mass that makes up the Cowley Park deposit is around 3000 ft. (914 m) and reaches a maximum of 1200 ft. (366 m). The skarn is copper stained, and copper minerals include bornite and chalcopyrite. Mineralization includes andradite, epidote, calcite, quartz, magnetite, wollastonite, and minor molybdenite.
A reserve estimate from 1971 concluded that there is 885 047 tonnes of ore at 0.89% Cu.
