The Chambers occurrence is located on Crown grant Lot 1752 at 1555 metres elevation above sea level, in the Slocan Mining Division. The claim is on the north side of Carpenter Creek, just east of Cody Creek. The property consisted of the Chambers (Lot 1752), Wellington (Lot 1755), Eureka and Jay Gould Crown (Lot 1754) grants located in 1891.
The workings include 5 adits at elevations that range from 1280 to 1560 metres. In 1951, a small crew of men reopened the workings; the property was owned at that time by J.M. Harris.
Reco Silver Mines Limited, incorporated June 1964, optioned the Chambers (Lot 1752) and adjacent claims from Mrs. Harris. Geochemical surveys were carried out in 1965 and 1968. The Chambers 4785 level adit, which had been driven about 37 metres in the 1890's, was advanced 46 metres in 1969; diamond drilling totalling 150 metres was done at that time. Rayrock Mines Limited obtained a working agreement with Reco Silver in March 1973. Silvex Resources Corporation held the property in 1980 and, in 1981, constructed a raise into a massive zinc horizon. Knie Resources Inc. optioned the property from Silvex Resources in 1983 and produced in 1984.
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 Chambers property is underlain by massive to slaty argillite of the Slocan Group and several small quartz porphyritic dikes probably related to the Nelson intrusions. At least four adits have been driven on a fissure vein that generally strikes northeast and dips 50 to 80 degrees south. The vein is within a 1.5 to 3 metres wide shear zone which is partly filled with quartz and crushed wallrock. Small ore shoots carrying argentiferous galena with minor sphalerite and pyrite are developed along the vein structure which has been followed for about 340 metres of strike length.
Production from the Chambers vein between 1896 and 1984 yielded 490,392 grams of silver, 236,055 kilograms of zinc, 96,425 kilograms of lead, 1611 kilograms of cadmium and 155 grams of gold from 2321 tonnes mined.
