The Cap showing is located 8 kilometres south of South Hazelton, on the west slope of Rocher Deboule.

The host rocks are porphyritic flows, breccias and fine-grained tuffs of the Upper Cretaceous Brian Boru Formation (Kasalka Group) which has been dated at 72 million years in the area (Geological Survey of Canada Open File 2322). The strata strike northeast in the area, dipping 20 to 30 degrees southeast.

The showing is an altered and fractured zone which strikes 070 degrees, dipping 70 to 80 degrees northwest. The zone ranges in width from 15 to 120 centimetres, containing pyrite, quartz, siderite, calcite, chalcopyrite and arsenopyrite. The zone has been traced for 100 metres on surface by several trenches and has been explored by two short adits and shafts. A 26 tonne shipment, to the Ladysmith smelter in 1917, produced 7,838 grams of silver, 93 grams of gold and 1,531 kilograms of copper. A subsidiary vein is located some distance east of the main vein. It strikes parallel to the main vein, is up to 1 metre in width and contains pyrite, sphalerite and chalcopyrite.

In 2007, a chip sample (76056) assayed 0.226 gram per tonne gold, 477 grams per tonne silver, 0.69 per cent copper, and 1.29 per cent zinc over 0.77 metre (Burgoyne, A.A., Kikauka, A. (2007-12-18): Technical Report on the Rocher Deboule Property).

Work History

Two claims, the Cap and Belton, were owned by Denis Comeau from about 1914. The adjoining Huckleberry claim was owned by Victor Preston. Exploration and development work was begun in open cuts, a shaft, and a short adit. In 1915 the Comeau property was reported to be under bond to P.E. Lessard and R.S. Shaw, of Edmonton. Four claims, the Cap, Belton, Beatty, and Hermes, were owned in 1916 by Messrs. Comeau, Johnson, and Norberg. Intermittent development work continued until March 1918. A crosscut tunnel was driven for 24.7 metres and the vein drifted on for 20.4 metres to the northeast, where a flat fault cut off the vein and for 27 feet to the southwest to connect with the shaft. At elevation 628 metres a tunnel was driven 62 metres very nearly parallel to the strike of the vein. Further exploration work was reported by Mr. Comeau in 1923 and 1929.

The Huckleberry claim (Lot 4272) and the adjoining Mandon claim (Lot 4273) (Mineral Leases M 90 and M 91, respectively) were part of a larger claim group purchased by Chapparal Mines Ltd. in 1970 from a private company, Loudel Explorations Ltd. Additional claims were staked, bringing the property to 94 claims and 11 mineral leases. Included in the Mineral Leases were the Golden Wonder property, about 1 mile to the west, and the Homestake (Lot 3309) and other old Crown grants about 2 miles to the east; these probably formed part of the Victoria and Hazelton View properties. Work during 1970 included magnetometer and induced polarization surveys, and 6 percussion drill holes totalling 314 metres. This work was confined to the Loudel group of located claims. Drilling on Loudel 1 and 2 claims cut low-grade copper mineralization. Adjacent ground to the north, formerly held by others as the Mark and Park claims, was staked by the company in 1971. Work during 1971 included a geochemical soil survey over 32 line-kilometres covering Loudel 1-6, aeromagnetic and induced potential surveys covering Loudel 58-68, trenching, and diamond drilling in 4 holes totalling 332 metres on Loudel 1, 2, and 7; diamond drilling in 1970 totalled 288 metres in 4 holes.

In the period 1969 to 1972 the claim was explored by Chapparal Mines Ltd, which conducted Induced Polarization and soil-sampling surveys, and drilled one hole to a depth of 282 metres. The company also made numerous long bulldozer trenches on the crest of the ridge.

In 1979 the claim, having again reverted to the Crown, was acquired by F.B. Lilhiting, who staked three claims totalling 41 units over surrounding ground. He later assigned a 70 per cent interest to Cobre Exploration Ltd. In 1980 work consisted of prospecting, geological examinations, and sampling of road cuts and bulldozer trenches in the pyritized zone.

In 1980 an airborne VLF-EM and Magnetometer Survey was flown Mandon 1-3, Mandon, Huckleberry claims for Cobre Exploration Limited on their Mandon project (Assessment Report 8705).

During 2001 through 2007, Rocher Deboule Minerals Corporation completed programs of rock and soil sampling, prospecting, geological mapping and an airborne (electromagnetic, magnetic and radiometric) geophysical survey on the area as the Rocher Deboule property. A diamond core drilling program of 1106.1 meters over 6 drill holes on the Highland Boy Showing was also conducted. Also, in 2006 and 2007, Crucible Resources Ltd held the RD property and conducted sampling on the Cap.

See Rocher Deboule (093M 071) for related details of work done on the Rocher Deboule property, of which the Cap was part of in the late 2000s.

In 2011, American Manganese collected 188 soil samples along the road system and the Capp soil grid. Of these 49 samples were greater than 2 grams per tonne silver, indicating a significant system 1500 metres east to west and 600 metres north to south and open to the north and south (Assessment Report 33297). Some rock sample was also completed. In 2012, American Manganese Inc. completed a minor program of rock and soil sampling on the area.

During 2016 through 2019, American Manganese Inc. completed further programs of geochemical (rock and soil) sampling and 10.2 line-kilometres of ground magnetic surveys on the area as the Rocher Deboule property.

Also, in 2017 and 2018, Primary Energy Metals Inc. completed programs of geological mapping and geochemical (rock, soil and stream sediment) sampling on the area as the Golden Wonder property.
