A number of quartz veins occur in the Lower Jurassic Hazelton Group rocks of the Telkwa Formation which is comprised mainly of variegated red, green, maroon to grey andesitic to rhyolitic tuffs, flows, and breccias. The veins have widths of a few centimetres to 1.5 metres with flat dips. The veins are irregularly mineralized with galena, tetrahedrite, chalcopyrite, pyrite, and arsenopyrite. Only small amounts of native silver occur in the high grade areas.
The main vein varies from 0.3 to 0.9 metres in width, striking east-west and dipping northwards at 33 degrees. A sample across 0.6 metres assayed 5.5 grams per tonne gold, 822.8 grams per tonne silver, trace lead, 0.3 per cent copper. A sample across 0.7 metres of the vein which hosted arsenopyrite and galena assayed trace gold, 411.4 grams per tonne silver, and 12 per cent lead. Another sample across 0.9 metres which showed arsenopyrite assayed 7.5 grams per tonne gold and 360 grams per tonne silver (Minister of Mines Annual Report 1920, page 91).
On the Morning Star claim 28 sacks of hand sorted ore was recovered from a 6.5 metre shaft along a mineralized quartz vein. A selected sample of the ore assayed 14.4 grams per tonne gold, 11,063 grams per tonne silver, 26 per cent lead, and 12 per cent copper (Minister of Mines Annual Report 1929, page 91).
