The Victoria occurrence is situated on the Victoria No. 6 Reverted Crown grant (Lot 3154) at 1265 metres elevation, about 800 metres north of Sandon. The property also includes the Galt Reverted Crown grant (Lot 5194).
The claims were granted in 1903 and 1902 respectively but nothing is known of early work on the claims. Between 1917 and 1925 John Worgan, then owner of the property, carried out intermittent development and mined a small amount of ore. In 1925 the Sandon Silver-Lead Mining Company, Limited, acquired the claims but did only a small amount of development work.
Workings include 3 adits over a vertical range of 47.2 metres. The uppermost is about 64 metres long and is driven in blocky granite porphyry and black argillites along a mineralized fault fissure striking about north 35 degrees east and dipping from 70 degrees southeast to vertical. No. 2 adit, 29 metres below No. 1, has been driven for 12 metres along a mineralized fault separating argillites and quartz porphyry. The fissure strikes N 30 degrees E, and dips 60 degrees to the southeast. No. 3 adit, 18 metres below No. 2. is 97 metres long. For the first 48.7 metres it follows a mineralized fault fissure striking about north 45 degres east and dipping 45 degrees to 75 degrees southeast. At 49 metres from the portal the adit meets a cross fault striking north 50 degrees west. From this point the adit was continued as a crosscut for 12.8 metres to where it meets the hanging wall of a quartz porphyry dyke; it follows this for a about a metre to where another fault striking north 25 degrees west was encountered. The adit follows this fault to the face, but no significant mineralization was encountered.
Regionally, the area lies on the western margin of the Kootenay Arc, in allochthonous rocks of the Quesnel Terrane. In the vicinity of the occurrence, the Quesnel Terrane is dominated by the Upper Triassic Slocan Group, a thick sequence of deformed and metamorphosed shale, argillite, siltstone, quartzite and minor limestone. Rocks of the Slocan Group are tightly and disharmonically folded. Early minor folds are tight to isoclinal with moderate east plunging, southeast inclined axial planes and younger folds are open, southwest plunging with subhorizontal axial planes. The sedimentary sequence has been regionally metamorphosed to lower greenschist facies.
South of the occurrence, the Slocan Group has been intruded by the Middle Jurassic Nelson intrusions which comprise at least six texturally and compositionally distinct phases ranging from diorite to lamprophyre. The most dominant phase is a medium to coarse grained potassium feldspar porphyritic granite. Several feldspar porphyritic granodiorite dikes, apparently related to the Nelson intrusions, also cut the sedimentary sequence near the occurrence (Paper 1989-5).
The property is underlain by banded, grey quartzite and black argillite of the Slocan Group. The sedimentary rocks strike northwest and form part of an anticline with limbs dipping 40 to 45 degrees southwest. The rocks are cut by quartz porphyritic and medium grained granite dikes and sills.
Three adits were driven over a vertical range of 50 metres. The adits explore a fissure vein developed at the contact between the Slocan sedimentary rocks and a quartz porphyritic sill. The vein strikes 035 degrees and dips 70 to 80 degrees southeast. The fissure vein varies from a few centimetres up to 90 centimetres in width. It is mostly filled with crushed rock and gouge. Galena, sphalerite and pyrite occur with quartz in small pockets and narrow shoots along the vein. The largest ore shoot, in the upper adit, was 3 metres long and 2.5 metres high.
Production between 1917 and 1918 yielded 4448 grams of silver and 1207 kilograms of lead from 3 tonnes mined.
