Capsule

The Whitehorse Copper Belt is located west of Whitehorse and contains 30+ mines, deposits and showings. 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 Black Cub North is located at the contact between the Lewes river limestone and the Whitehorse batholith granite. The visible skarn is garnet rich and has minor amounts of bornite and malachite. Economic elements include Cu, Ag, and Au.

The Black Cub north deposit was determined to contain 156 035 tonnes at 0.82% Cu in 1971.
