The Copper King North (Zone 14) occurrence is located at an elevation of 960 metres on the north side of the White Range.

The area is underlain by Upper Triassic Vancouver Group rocks consisting of Karmutsen Formation basalts overlain by Quatsino Formation limestone. These are intruded by the Jurassic Island Plutonic Suite consisting dominantly of quartz diorite with lesser diorite and granodiorite. A number of skarn showings are scattered within all three major rock units and at their contacts. Several of the skarns within the Karmutsen basalts are conformable, occupying highly amygdaloidal flow tops.

The zone 14 skarn occurs along a vertical fault and hosts magnetite and garnet with minor chalcopyrite mineralization over and area of 300 by 10 metres. A grab sample (13799) assayed 5.05 per cent copper and 31 grams per tonne silver (Assessment Report 8037).

In 1963, Mastodon-Highland completed a program of geological mapping and a ground magnetometer survey on the area as the Gam claims. During 1973 through 1977, W. Babkirk prospected the area as the Donner and Heber claims. In 1978, Mont Alta Projects Ltd. completed a program of rock sampling and ground geophysical surveys on the area as the Donner Lake property. In 1979, CON-AM Resources optioned the property and completed a program of geological mapping, rock sampling and a ground magnetometer survey.
