The Fairy property is situated near the headwaters of Howson Creek at 2073 metres elevation above sea level, in the Slocan Mining Division. The underground workings are on Reverted Crown grant Lot 4508.
It was Crown-granted to J.G. Steel in 1900 and to H.H. Falding in 1917 and 1925. In about 1950 the claim became a part of the holdings of Silver Ridge Mining Co. Ltd.
An adit was driven 61 metres westerly at an elevation of 2039 metres. At 58 metres the drift turns to the southwest to follow light shearing into which the mineralized fracture swings at 21.3 metres from the portal. A branch extends 20 metres to the south in limy rock. The records do not indicate when or by whom this development work was done.
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 very fine grained clastic sedimentary rocks of the Upper Triassic Slocan Group that include locally weakly metamorphosed argillite, quartzite, limestone and some tuffaceous rocks. These sedimentary rocks are intruded by dikes, sills and stocks of varied composition and origin. Permian and/or Triassic Kaslo Group metamorphosed volcanic rocks occur to the north of the Slocan Group rocks. Middle Jurassic Nelson intrusions are immediately south of the Slocan Group and are inferred to be the source of granitic to pegmatitic sills and dikes found in the area. The Nelson intrusions 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 (Paper 1989-5).
The occurrence is hosted by predominantly interbedded black argillite, quartzite and limestone of the Slocan Group. The sedimentary rocks have been folded, fractured, faulted and regionally metamorphosed to greenschist facies. The regional northwest trending asymmetric Slocan syncline is thought to be Middle Jurassic and is the first recognizable deformation in the sequence. Several fault structures are evident and host vein mineralization. Later stage normal and thrust faults and shearing have chopped, deformed and remobilized the veins and mineralization. Drag features are also present.
On the Fairy property the sedimentary rocks strike 145 degrees and dip 50 degrees northeast. The occurrence consists of a narrow brecciated shear zone within black argillite. The shear contains several calcite veins 10 to 15 centimetres in width. The calcite veins carry minor disseminated sphalerite.
