The MG 3 showing is located on the east-central portion of the Barite 1 claim, near Cullen Creek, a tributary of the Bear River, about 50 kilometres northeast of Stewart.
The area is underlain by Jurassic Hazelton Group rocks. These comprise andesitic tuffs and breccias of the Lower Jurassic Unuk River Formation and volcanic sediments and tuffs with minor chert and limestone of the Lower Jurassic Betty Creek Formation. At the mouth of Cullen Creek is a small monzonite stock probably related to the Tertiary Bitter Creek dike swarm.
The showing is underlain predominantly by volcanic (probably andesitic) tuffs, breccias and conglomerates. The northeast trending Cullen Creek fault/shear zone is the main structure in the area. A quartz vein, containing sphalerite, chalcopyrite, pyrite and galena, is up to 20 centimetres wide and can be traced for over 80 metres. The vein strikes 134 degrees and dips vertically.
Chip samples (MR-270A, B, C, D and E) assayed 2.72 to 5.84 per cent copper, 119.3 to 255 grams per tonne silver, 0.41 to 15.92 per cent zinc and 0.32 to 3.32 per cent lead (Assessment Report 22033). One sample (MR-270D), containing 20 per cent chalcopyrite, 10 per cent pyrite and 50 per cent sphalerite, assayed 144.8 grams per tonne silver, 3.08 per cent copper, 9.28 per cent zinc and 3.08 per cent lead (Assessment Report 22033).
The area has seen some exploration activity, primarily associated with the Crown-granted claims. There are no records of this work but there is evidence of prospecting and trenching. The work was most likely done in the 1970s and 1980s. In 1989, the Barite and Von claims were acquired by Teuton Resources. In 1990, Teuton Resources conducted stream sediment sampling, geological mapping, rock geochemical sampling and prospecting. In 1991, Teuton conducted geochemical (soil and silt) and rock sampling. In 1994, a helicopter-supported program on the Golden Crown property by Canstar Ventures Corporation consisted of collecting 450 samples including 369 rock composite and chip, 2 soil, 58 stream sediment and 21 checks in ten target areas.
