The Bulldog occurrence is located on a southeast-facing slope, west of Matthew Creek, at an elevation of approximately 1600 metres.

The area is underlain by argillites and quartzites of the Mesoproterozoic Aldridge Formation (Purcell Supergroup). These have been intruded by gabbro sills and dikes of the Middle Proterozoic Moyie Intrusions.

Locally, historical workings expose quartz veining, up to 12 metres wide, in slatey argillites, mica schists, quartzites and a meta-diorite over an area of approximately 700 by 200 metres extending in a northwest direction. Sulphide mineralization is reported to include galena, chalcopyrite, covellite, bornite, pyrite, pyrrhotite and possible molybdenite. Tourmaline and graphite are also reported.

Two more zones of mineralization are reported approximately 1.4 and 1.7 kilometres to the southwest. The first consists of small sulphide lenses of pyrrhotite-chalcopyrite-bornite in quartz boudins with limonite staining in a chloritic and micaceous host, whereas the later consists of an oxidized and fractured pegmatite. In 2010, two samples (CK09-118 and 119) from the first zone assayed 0.156 and 0.168 per cent copper, respectively, whereas a sample (CK09-139) from the second zone assayed 0.366 per cent lead and 5.8 grams per tonne silver (Assessment Report 31614).

Work History

Historical workings in the area consist of several pits and trenches, two shafts, an adit and an ore or waste dump by the adit, likely dating to the early 1900s.

In 1971, Kerr Addison Mines Ltd. conducted a regional program of geological mapping and geochemical (soil and silt) sampling on the area as part of the Dewar Creek project.

In 1985 and 1986, Amstar American completed programs of geological mapping, soil and rock sampling and ground and airborne geophysical surveys on the area as the Denver claims.

In 1994, a program of rock and soil sampling and geological mapping was completed on the area as the Ham claim group by Shaun Hamilton.

During 1996 through 1999, Eagle Plains Resources Ltd. and Miner River Resources Ltd completed programs prospecting, geological mapping and geochemical (stream sediment, silt, soil and rock) sampling on the area immediately north as the Bootleg 1-4 claims. Stream sediment samples (RBBLSS-01 through -07), taken from an area centered approximately 3.5 kilometres to the northwest of the Bulldog occurrence, yielded anomalous values of copper (92 to 1009 part per million), zinc (196 to 384 parts per million), lanthanum (130 to 280 parts per million) and yttrium (60 to 124 part per million), whereas soil sampling in the same area yielded values of up to 130 parts per million lanthanum and 273 parts per million yttrium (sample L2100N 0+00W; Assessment Report 24907 and 26186).

In 2009 and 2010, Kootenay Gold prospected and rock sampled the area as the MS Peg property. In 2014, the MS Peg property was prospected and rock sampled by C. Kennedy. In 2023, Andris Kikauka conducted a minor program of prospecting and geochemical (rock and soil) sampling on the Peg property.
