The L and L occurrence is located on the middle fork of Glacier Creek, south of the Black Hills Glacier and 8.5 kilometres northeast of Stewart. Several shipments of high-grade ore were made between 1913 and 1927.
The occurrence consists of several veins hosted in a 3 kilometre long by 2 kilometre wide Tertiary(?) augite diorite stock (Coast Plutonic Complex) that intrudes argillite of the Middle Jurassic Salmon River Formation (Hazelton Group).
The most extensive mineralization occurs in a 0.60 to 1.5 metre wide quartz breccia vein. The vein strikes 156 degrees for 350 metres and dips 73 degrees southwest, extending downdip for at least 120 metres. The vein is developed adjacent to a subparallel feldspar porphyritic dike. Faulting has caused 1.0 to 2.0 metre displacements of the vein.
Mineralization consists of sphalerite, pyrite, arsenopyrite and minor galena, tetrahedrite, pyrrhotite and chalcopyrite. The mineralization is confined largely to a 0.3 to 0.8 metre wide, 36 metre long and 36 metre deep ore shoot on the hangingwall of the vein. This ore shoot contains 63.5 tonnes of indicated (proven) reserves and an additional 172.4 tonnes of inferred (possible) reserves for a total of 326.6 tonnes over a 0.3 metre width, averaging 2057 grams per tonne silver (Assessment Report 10046, page 12). The entire vein contains inferred (possible) reserves of 18,000 tonnes within a 180 metre long, 120 metre deep, 0.6 metre wide block grading 0.27 gram per tonne gold, 31 grams per tonne silver, 2.1 per cent zinc and 0.36 per cent lead. A potential for 118,000 tonnes of similar grade is contained in the southeastern extension of the vein (Property File - Prospectus, Morocco Explorations, 1988, page 18).
A parallel 2 metre wide shear zone, 60 metres to the southwest, contains a quartz vein up to 0.3 metre wide mineralized with pyrite, sphalerite, and some arsenopyrite. A selected grab sample assayed 0.87 gram per tonne gold, 30.2 grams per tonne silver, 0.36 per cent lead and 2.18 per cent zinc (Assessment Report 15305, page 13).
Between 1913 and 1925, 63 tonnes of sorted ore were mined, with an average grade of 3.1 grams per tonne gold, 6292 grams per tonne silver and 13.7 per cent lead, 15.6 per cent zinc and 0.01 per cent copper.
In 1924, work by L & L Glacier Creek Mines, Ltd. consisted of four opencuts tracing the vein a distance of over 91 metres. Each cut exposed a few centimetres up to 0.9 metre of heavy sulphide ore of sphalerite and arsenopyrite with some galena and tetrahedrite. Under these surface exposures, a tunnel had been driven on the vein a distance of 68 metres extending under the first two surface cuts and about up to the third one without intersecting any appreciable amount of ore such as exposed on the surface, though some good grade ore was encountered at about 46 metres from the portal. The tunnel was continued 18 metres bearing to the right thus crosscutting the formation for about 9 metres, but without encouraging results. An upper tunnel was then started at the lowest opencut, about 21 metres vertically above the main tunnel, and driven about 36 metres by the end of 1924. This tunnel is in high-grade ore varying from 20 to 76 centimetres in width from the collar to the face. The face is in 42.6 metres and still in high-grade ore, obtaining a depth of about 24 metres. This upper tunnel shows the vein to have been faulted in two or three places, the lateral displacement being up to 1.5 or 1.8 metres. A raise was driven from the lower tunnel starting about 36.5 metres in from the portal, just north of a short crosscut. In cutting out for this raise, high-grade ore was intersected and has continued continuously for the 12 metres raised to date (ca. 1924). The vein in the raise is from 30 to 76 centimetres wide.
In 1986, an exploration program on behalf of Silver Bar Resources Ltd. was designed to assess the mineral potential of the property beyond the main workings areas. Part of the property was mapped and prospected, two grids established, soil samples collected and a VLF-EM survey conducted. In 2006, Teuton Resources Corp. completed 228.1 line-kilometres of a helicopter-borne AeroTEM II electromagentic and magnetic survey on their Silver Bell property which covers the showing area.
