The location of the Montreal showings is not known exactly. Several showings are reported on the Montreal 1-8 claims, which are reported to lie immediately east of the Murdock claims (104A 128, Lots 3440-3446)(Minister of Mines Annual Report 1925, page 94). The claims are assumed to have been staked on the north side of Strohn Creek about 4.5 kilometres east of the Bear River Pass, 31 kilometres northeast of Stewart.
The area is underlain by north striking Jurassic Hazelton Group rocks. The Lower Jurassic Unuk River Formation is unconformably overlain to the east by the Middle Jurassic Salmon River Formation (Bulletin 63). The Salmon River Formation rocks are intruded by an Eocene(?) stock of quartz monzonite to the east of the showings. Several showings have been reported on the Montreal claims.
At about 594 metres elevation (immediately below the old camp), several opencuts expose disseminations and stringers of galena and sphalerite in volcanic breccia. A chip sample assayed trace gold, 13.7 grams per tonne silver, nil lead and 1.5 per cent zinc across 4.6 metres (Minister of Mines Annual Report 1928, page 111). At about 617 metres elevation, argentiferous galena occurs in a shear zone in a 6 metre long tunnel. At 732 metres elevation, a 6 metre wide pyritic silicified zone is exposed in a creek.
At 640 metres elevation, a silicified zone in greenstone carries minor pyrite, sphalerite and rare galena stringers. The zone strikes north, dips west and is up to 10 metres wide. A grab sample from a tunnel, 13.7 metres long, assayed 68.6 grams per tonne silver and trace gold (Minister of Mines Annual Report 1928, page 111).
Float samples of highly leached material containing quartz and galena assayed 0.7 gram per tonne gold, 1542.9 grams per tonne silver and 43 per cent lead (Minister of Mines Annual Report 1928, page 111).
The Montreal claims were located in 1925 by Douville and others. Four veins, 1.8 to 7.6 metres wide, were reported that year. During 1925-29, the owners completed several opencuts and at least two tunnels.
During 2005 through 2010, Auramex completed programs of prospecting, geological mapping, geochemical sampling and airborne geophysical surveys on the area as the Bear River-Surprise Creek property.
