The Bik-Mess Creek claim is underlain by Devonian buff coloured limestone, phyllite, greywacke and andesite that have a sub-schistose texture. These are overlain to the west by Upper Triassic volcanics which consist of massive andesites, basaltic augite porphyry and flow breccias and tuffs. Conglomerate and sandstones overlie these volcanics unconformably to the west and are, in part, of the Jurassic Hazelton group and, in part, of an Upper Triassic to Lower Jurassic unit of an unknown affinity. A Middle to Late Triassic sill-like mass of diorite to syenite occurs along the faulted contact that separates the Triassic to Jurassic conglomerates from the Devonian rocks on the east. Younger lamprophyric and andesitic dikes cut the rocks near the dioritic sill.
The Devonian and Triassic rocks strike northeast and dip at about 60 degrees northwest. The sill is more or less concordant with these. The Jurassic rocks strike northwest and dip 25 to 30 degrees southwest. The volcanics in the north part of these claims are cut by a spray of faults.
The principal showing is near the centre of a large outcrop of fossiliferous limestone. Here thin sheets and irregular blebs of tetrahedrite with some associated malachite stains are found with translucent quartz along a weak system of flat joints. A sample of this material contained 819.0 grams per tonne silver, 13.0 per cent copper, 2.8 per cent zinc, 0.2 per cent lead, and a trace of gold (Assessment Report 590). "Weak copper mineralization was also found along systems of sub-vertical north-south trending brittle shears. Mineralization consists of malachite, azurite, and minor chalcopyrite hosted in andesites and tuffs of probable Triassic age. Another showing of weak chalcopyrite, over an area of 3 by 9 metres, is found in silicified basalts with carbonate material. A 1.5 metre chip sample contained 0.66 per cent copper and only traces of gold and silver. Several other minor occurrences of chalcopyrite and tetrahedrite have been identified within the claim area and adjacent to it.
In 2018 an Assessment Report study was completed Wild West Gold Corp. on their Bik claim that measured about 0.5 square kilometre in area. The study was an interpretation of the results of government-flown magnetic and gravity surveys as well as a government-funded regional geochemistry stream sampling survey (RGS). The BIK showing was to occur close to the intersection of two lineations and within a magnetic low near a magnetic high.
In 1964, a program of mapping, prospecting and stream sediment sampling was carried out by Silver Standard Mines on their BIK 161-196 claims. Copper showings had been reported several years before the actual staking by prospectors working for Silver Standard. The ground was staked quickly following rumours of important mineral development at Galore Creek. In the course of work during 1964 several copper showings were found on the property.
