The Vulture occurrence is located at 1646 metres elevation above sea level in the Slocan Mining Division. The occurrence lies on Reverted Crown grant Lot 4482.
Most of the underground workings on this claim were driven prior to 1900, and in 1899 the first and largest shipments of ore were made.
Two adits have been driven at elevations of 1524 and 1578.8 metres. The upper adit is 74.6 metres in length and contains about 15.2 metres of crosscuts. At a point 19 metres from the portal a raise has been put up to the surface and in addition there are 2 small stopes, and a winze of unknown depth at 26 metres from the portal. The lower adit is about 53.5 metres long, with the face located approximately under the winze in the upper adit. At 15.2 metres from the portal there is a 39.6-metre drift. No mineralization of value is reported from this adit.
In January 1951 Slocan Lode Mines Limited was formed to develop the claim. In 1952 the workings were rehabilitated, and a stope prepared near the portal. Little work was done in 1953 and there is no record of subsequent development.
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 Vulture Reverted Crown grant is underlain by quartzite, calcareous argillite and slate of the Slocan Group. The strata are folded in a northwest-trending syncline with limbs dipping at low angles to the north and south. Two adits have been driven about 55 metres apart. The upper adit is 75 metres long and follows a galena-sphalerite fissure vein less than 60 centimetres wide. The lower adit extends for 53 metres in a northerly direction along the vein but no worthwhile mineralization was intersected (Minister of Mines Annual Report 1952). The vein strikes 050 degrees and dips 40 to 50 degrees southeast. The vein is cut off by a fault that parallels a vertical east trending granite dike. The fault may have a left-lateral displacement with the major dislocation being along the bedding plane (Assessment Report 22791).
Very intermittent production between 1899 and 1953 yielded about 1624 kilograms of silver, 368,625 kilograms of lead and 208 kilograms of zinc from 531 tonnes mined.
