The Granite Mountain or Mad showing, and the Chris showing (093B 063) comprise the Copper King property. Road access to the property from Williams Lake is excellent and gained by driving 45 kilometres north on Highway 97 to McLeese Lake, then east on Beaver Creek road (Gibraltar Mine road) for 3.3 kilometres, then 9 kilometres east on the Beaver Lake road and north 10.7 kilometres on forest access road 609. Numerous secondary roads and trails traverse the property making most areas of the property easily accessible.

The Granite Mountain showing is located near the eastern margin of the Stikine Terrane in south-central British Columbia. The dominant rock types in the region are metabasalt, limestone and argillaceous metasediments of the Mississippian to Triassic Cache Creek Group. These are intruded by Early Jurassic dioritic to quartz dioritic intrusive rocks of the Granite Mountain pluton and the Cretaceous Sheridan Creek pluton. The Granite Mountain pluton has been affected by regional metamorphism (greenschist facies) and deformation along with the enclosing Mississippian-Triassic Cache Creek Group.

Mineralization at the Granite Mountain showing consists of scattered pyrite, chalcopyrite, malachite and molybdenite within shear zones and northwest striking quartz veins in quartz diorite of the Granite Mountain pluton.

In the area of the Copper King property, limited exploration work has been carried out intermittently since the 1960s. Gunn Mines Ltd. carried out magnetometer surveys, induced polarization surveys and 12 diamond-drill holes totalling 1068.6 metres in the area of the claims between 1967 and 1971. In 1970, Primac Exploration Services Ltd. completed geological, magnetometer and soil geochemical surveys to the south of the Copper King property. In 1998, 28.4 kilometres of grid (North Grid) was established, 562 soil samples taken and 26.4 kilometres of ground magnetometer and VLF-EM surveys were completed on the property. In addition, 17 kilometres of grid (Mid Grid) was established, 333 soil samples taken and 26.4 kilometres of ground magnetometer and VLF-EM surveys completed on the property. This work was carried out by Crest Geological Consultants Ltd. on behalf of United Gunn Resources Ltd. It identified an area of anomalous copper in soils located in the northeast comer of the property. Prospecting discovered a zone of epidote-chlorite altered lapilli tuff mineralized with pyrite and chalcopyrite disseminations and stringers. In addition, a north-northwest trending 1400 by 75 metre zinc-in-soil anomaly was also identified. In 2005, Copper Ridge Explorations Inc. completed two lines of reconnaissance soil sampling and induced polarization geophysical surveys. A total of 63 soil samples and 2 rock samples were collected from the property. The limited soil sampling results indicate that several, weak isolated anomalies occur on the Copper King property. The most prospective area appears to coincide with a mapped unit of massive, fine grained intermediate tuff traversing the southwestern part of the survey area. A total of 3.0 kilometres of induced polarization and magnetometer surveys were completed. Results from the induced polarization survey suggest that sulphides are not abundant in the underlying rocks. The 2006 exploration program was completed on behalf of Copper Ridge and included wide spaced, reconnaissance soil sampling as part of an overall program that included the Copper Ace South, Copper King, Sheridan and McLeese claim groups, all in the vicinity of the Gibraltar Mine. Of the total 1088 samples collected, 554 were from the Copper King property, with samples collected every 50 metres along 500 metre spaced lines.
