Discovered in 1998 by United Gunn Resources Ltd., the Chris showing (part of the overall Copper King property) is about 6.5 kilometres northeast of the Gibraltar mine (093B 012). The Chris showing and the Granite Mountain showing (093B 052) 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 Copper King property is underlain by three major rock types. The western parts of the property are underlain by massive tonalite of the Early Jurassic Granite Mountain pluton. The rocks are equigranular, leucocratic and buff white in colour. They are locally very coarse grained and quartz porphyritic. Quartz ranges from 35-65 per cent and up to 1 centimetre locally. Moderate to intense, northwest trending foliation fabrics are common and epidote-chlorite altered shear zones are developed locally. The eastern parts of the property are underlain by intermediate volcanic and volcaniclastic rocks of the Upper Triassic to Lower Jurassic Nicola Group. The rocks are andesitic to dacitic in composition and consist of lapilli ash tuffs, ash tuffs and flow breccias. Interbeds of limestone and tuffaceous limy mudstone occur locally. Rare cherty beds are also present. In the central part of the property there is a rectangular fault bounded panel of quartz diorite interpreted as a border phase of the Granite Mountain pluton. The rocks are typically massive, undeformed and texturally variable ranging fiom fine to coarse grained. Subangular zenoliths of epidote-altered volcanics and fine grained quartz diorite occur locally.

At the Chris showing, disseminated and fracture controlled chalcopyrite mineralization is hosted in quartz diorite (chlorite-sericite schist) of the Granite Mountain pluton. Assay values of 0.23 per cent copper occur in a 150 by 45 metre area (GCNL #213 (November 5, 1998)).

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.
