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 claims are situated in the overburden-covered Yukon River valley. The Foot occurrence consists of copper mineralization hosted by a bed of Lewes River Group skarnified limestone near its contact with a small body of mid-Cretaceous Whitehorse Plutonic Suite granite (Hart, 1997). Kindle (1964) reports that the workings, two small shafts, are located about 370 m west of the caved Anaconda adit (Minfile Occuurence #105D 200).

A copper bearing skarn zone, 30 m long and 10 m wide is found in limestone about 13 m north of the granite contact (Kindle, 1964). Bornite is found in the shafts across a 2.2 m width of skarn rock. Prominent secondary minerals include wollastonite, epidote, garnet, and augite. About 125 m northeast of the shaft area bornite and chalcopyrite impregnate skarn rock over a 10 m exposure and averages >1 % Cu.

Hudson Bays 1984 drill hole tested a northerly trending weak EM-16 and Max-Min conductor. It encountered 60.5 m of overburden followed by granodiorite (Stroshein, 1984). The 1987 hole tested the same conductor and intersected limestone, marble, and granodiorite. A 2.75 m wide calcareous -carbonaceous clay zone was the presumed source of the electro-magnetic anomaly (Stroshein, 1987).

The 1976 drill hole collared on the We claims intersected traces of chalcopyrite, molybdenite, cuprite and native copper in diorite. The 1977 hole tested an IP anomaly and intersected pyritic quartzite. The 1981 holes tested geological targets and did not intersect copper mineralization.

In 1995 Hamel trenched on the Hat claims and exposed two mineralized limestone exoskarns and a mineralized granodiorite endoskarn 200 m north of the defunct War Eagle open pit. Rock samples yielded up to >7 000 ppb gold and 8.91 % Cu (Peer, 1997). Further excavator trenching and sampling in 1998 returned several samples grading >0.5 % Cu over 5 m (Peer, 1998).
