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 Verona showing is a magnetite-rich skarn within the Lewes River Limestone and completely surrounded by the granodiorite of the Whitehorse batholith. The granodiorite is epidotized and garnetized. The limestone inclusion is altered to epidote, garnet, and chlorite and is replaced by magnetite and bornite.
A sample of ore collected in 1909 was assayed and contained 0.005 oz. per ton (0.16 g/t) Au, 0.2% Cu, 49.7% Fe, 0.03 % Co, 0.04% Ga, and 0.12% manganese.
