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.
Unlike the other deposits within the Whitehorse Copper Belt, the Scheelite deposit is a pegmatitic quartz vein within the Whitehorse batholith hornblende granite. The 100-foot long and 4 foot wide quartz vein carries minor amounts of copper, tungsten and molybdenum and strikes mostly east. In parts of the vein, white scheelite forms over 5% of the vein matter and is sometimes associated with molybdenum.
A chip sample collected across the vein in the trench assayed 0.015 ounce per ton (0.47 g/t) Au, 1.7% Cu and 0.38% W.
