The Cole occurrence is located 3 kilometres east of Owen Lake, 34.0 kilometres south of Houston and about 1 kilometre northeast of the Silver Queen mine. The Cole Vein system includes the Cole Vein, Cole Shear, Bear Vein, Copper Vein, Barite Vein and NGF-6 Vein.

The area of the showings is primarily underlain by an Upper Cretaceous series of volcanic rocks and intrusions of the Kasalka Group and Bulkely Plutonic Suite, respectively. The volcanic rocks consist mainly of dacites and dacitic andesites that are likely part of the Francois Lake Group, Tip Top Hill Formation which are more recently thought to be correlative with Kasalka rocks. A sill-like body of microdiorite dated as 75.5, plus or minus 1.0 million years (N. Church, Bulletin 78, Table 2.3), intrudes these volcanic rocks.

The showings are mainly hosted by a kaolinized and pyritized dacitic volcanic breccia with the microdiorite lying to the west. Pulaskite, dikes occur in the vicinity of some veins. At least five veins have been discovered that host sulphide minerals consisting mainly of sphalerite, galena and pyrite with some accessory chalcopyrite. The gangue is composed of cherty quartz, carbonate minerals such as rhodochrosite and some barite. Work on the showings has mainly been in conjunction with work on the adjacent Silver Queen (093L 002).

Concentrations of gallium, germanium and indium are also present. A recent resampling program returned average values of 22 grams per tonne gallium, 2.6 grams per tonne germanium and 23.35 grams per tonne indium (as reported in Assessment Report 32172).

The Diamond Belle vein was the focus of early exploration hosting the Cole Shaft. The vein averages 0.6 to 0.9 metre in width striking 130 degrees and dips steeply over the central part with the southern part striking easterly before pinching out against the pulaskite dike which strikes 150 degrees. Mineralization consists of sphalerite, galena, pyrite, and minor chalcopyrite in a gangue of quartz, carbonate, rhodochrosite and barite.

The Shear vein, near the east end of the Diamond Belle veins, strikes northerly and dips near vertically over an exposed length of 213 metres. The mineralization is patchy and appears to be the result of replacement and cavity infilling in a shear.

Vein mineralization striking southeast and parallel to the Diamond Belle, located 15 metres to the south, assayed over 1.0 metre width, 2.4 grams per tonne gold, 637.7 grams per tonne silver, 1.3 per cent copper, 2.2 per cent lead, and 5.5 per cent zinc.

The Bear vein, located 300 metres southwest of the Cole shaft, strikes south for approximately a 67 metre exposure. A chip sample across the vein yielded almost pure amber sphalerite with minor pyrite hosting modest precious metal values and cadmium.

The Barite vein, located 150 metres west of the Cole vein system, strikes southeast discontinuously for 107 metres in length. A gangue rich sample over 107 centimetre width assayed trace gold, 92.6 grams per tonne silver, 0.04 per cent copper, 0.58 per cent lead, 1.1 per cent zinc, 12.9 per cent iron, 7.8 per cent manganese, 0.36 per cent calcium, trace cadmium, 0.07 per cent arsenic, and 0.03 per cent antimony.

The NGV vein, located in the southern part of the prospect area, strikes 160 degrees dipping 75 degrees northeast and is exposed for 50 metres. In 1970, a 76 centimetre piece of mineralized drill core assayed 1.37 grams per tonne gold, 447.5 grams per tonne silver, 0.17 per cent copper, 12.8 per cent lead, and 10.2 per cent zinc.

PRE-1985 HISTORY - Cole Lake Property
In 1915, Cole vein system staked as the Diamond Belle group.

In 1928, the property was acquired, along with the Silver Queen property, by the Owen Lake Mining and Development Company; Cole shaft sunk.

In 1941, Canadian Exploration optioned property, completed mapping and sampling. Option dropped in 1943.

In 1967, considerable trenching and some drilling was done on the Cole Lake veins by Frontier Explorations Ltd, who had acquired the ground in this area in 1960, and done minor work in the early 1960s.

In 1972, Frontier Explorations did EM survey, as well as percussion drilling and 457 metres (1,500 ft) of diamond drilling on George Lake Lineament Vein 1980 - backhoe trenching done by Frontier.

In 1981, New Frontier sold all its mining interests to Bulkley Silver Resources Ltd, who attempted to raise money to complete the Earl Adit which would intersect the Cole Vein system at depth. Insufficient funds were raised and only 30.5 metres (100 feet) of this drive was completed.

In 2011, New Nadina Explorations Limited conducted ZTEM and Quantum 24 geophysical surveys. The aeromagnetic and electromagnetic survey covered 708.4 lines-kilometres and covered all mineral occurrences on the Silver Queen property including: the Silver Creek (Wrinch) (093L 002), Camp/Portal (new), Chisholm (093l 216), George Lake (new) and Cole (093L 162) systems and the Itsit porphyry (new).
