The Silver Bear occurrence is located at 1460 metres elevation midway between Desmond and Kyawats creeks, southeast of Keen Creek. The ground was covered by the former Silver Bear claim group, composed of the former Silver Bear and Broughton Crown grants. Kaslo, British Columbia is located 22 kilometres to the northeast.

Work began on the Silver Bear occurrence in 1919. During this year the claim was worked by the owners of the neighbouring Silver Bell occurrence (082FNW187). The claim was acquired by M.S. Davys in 1920 and worked intermittently until 1927. The following year, F. Helme acquired the property and also worked it intermittently until 1943. In 1951, a lease was granted to S. Hallgren, who in turn sub-leased the property for two years. Abacot Mines Ltd. acquired the Silver Bear and Broughton claims in 1953. The lowest level was restored and a small shipment of ore was reported made before the mine shutdown. N.E. Cloggie acquired ownership in 1956 and made a shipment of ore mined in the previous year. Cream Minerals Ltd. sampled the property in 1997 and reported up to 4536.5 grams per tonne silver, 6.20 per cent zinc and 15.59 per cent lead (GCNL #167, 1997). A 35-metre trench sample assayed 221.5 grams per tonne silver, 2.40 per cent zinc and 1.57 per cent lead (GCNL #230, 1997).

In 1998, Cream Minerals completed 10 diamond drill holes on the Silver Bear occurrence. Drilling intercepts included 102.6, 1877.1 and 574.5 grams per tonne silver, 0.79, 22.6 and 1.09 per cent lead with 1.21, 5.34 and 5.22 per cent zinc over 1.96, 0.51 and 0.54 metres, respectively, in holes 98SB-02, -05 and -06 (McBride, D.E. (2014-04-15): NI 43-101 Technical Report on the Kaslo Property).

In 2004, Cream Minerals completed a further two diamond drill holes under a nearby road outcrop but were reported to have failed to intersect meaningful mineralization.

In 2013, Agave Silver Corp. examined the area as the Kaslo property

The Silver Bear shear zone has been traced for 1.2 kilometres. It averages 25 metres in width and hosts 3 sub-parallel mineralized bands. This shear may be the southern extension of the Gold Cure shear zone (see 082FNW096, 097, 185). Eight diamond drill holes were completed in 1998.

The property is developed by six adits, three or more intermediate levels and several opencuts. Underground workings aggregate over 914 metres. The principal workings are three crosscut adits that explore the main lode over a vertical range of 104 metres.

The Silver Bear occurrence occupies a narrow belt of Triassic Slocan Group metasediments within the Keen Creek reentrant. Metasediments, in order of importance, include slate, carbonaceous argillite, limestone, siltstone and biotite andalusite schist. Slocan lithologies are flanked by hornblende potassium feldspar porphyritic granite of the Middle Jurassic Nelson batholith and potassium feldspar porphyritic granite of the Middle Jurassic Mount Carlyle stock.

Two nearly parallel mineralized lodes, 24 metres apart, comprise the Silver Bear occurrence. These lodes have a general strike of 045 degrees and a dip of 65 degrees to the southeast. Each lode is composed of quartz-calcite-siderite veins in brecciated and crushed wallrock along the contact of slate and limestone that are part of a band of Slocan sediments with synclinal dips away from flanking granitic intrusions of the Nelson batholith. Galena, sphalerite, pyrite and silver-bearing sulphides occur as irregular replacements in limestone. The main or "footwall" lode has been traced for over 305 metres in underground workings. Most of the work has been done on the west or "footwall" lode. The hangingwall is marked by a heavy clay gouge. Most of the production has come from between the No. 2 level and surface. The main shoot had a maximum length on the No. 2 level of about 27 metres. The east or "hangingwall" lode is similar in character to the "footwall" lode but significant mineralization was not discovered. A third lode is intersected by an old adit six metres above the No. 1 crosscut adit and has been only lightly prospected.

A total of 459 tonnes of ore have been mined from the Silver Bear occurrence producing 791,074 grams silver, 93 grams gold, 10,213 kilograms lead and 8910 kilograms zinc.
