The General James M. occurrence is located on a ridge to the east of Tranquil Creek, approximately 4.3 kilometres north east of the creek mouth.

Diorite to quartz-diorite of the Early to Middle Jurassic Island Plutonic Suite or the Paleozoic and/or Mesozoic West Coast Complex intrude Upper Paleozoic Sicker Group volcanics and Buttle Lake Group sediments. Magnetite-copper skarns and veins located along the igneous/volcanic contact, are localized by calcareous sediments and limestone, which likely belong to the Upper Pennsylvanian to Lower Permian Mount Mark Formation (Buttle Lake Group). The volcanics include porphyritic andesite.

At the General James M. workings, three steeply dipping, east trending, sub-parallel veins occur. The main adit vein is 2.0 metres wide and 10 metres long. The hanging wall consists of porphyritic andesite and breccia. Mineralization consists of chalcopyrite, magnetite, pyrrhotite, pyrite, garnet and epidote. In 1985, two sample (2802 and 2803) of dump material from the adit assayed 5.5 and 2.7 per cent copper with 54.9 and 30.9 grams per tonne silver (Assessment Report 14337). In 1987, a one metre chip sample (BCW-87-8) of massive sulphides at the entrance to the adit assayed 4.32 per cent copper, 36.7 grams per tonne silver and 0.15 per cent zinc (Assessment Report 16354).

A second adit, now collapsed, is located about 30 metres north of the main adit. This is situated on a 2.5 metres wide skarn zone that can be traced for 10 metres. In 1991, sampling of the skarn assayed up to 1.83 per cent copper and 14.8 grams per tonne silver over 0.25 metres (Assessment Report 21136).

Another mineralized vein occurs 20 metres east of the collapsed adit and is thought to be a separate vein from the one exposed by the main adit. In 1991, a sample (4) from the vein assayed 3.38 per cent copper and 43.6 grams per tonne silver 0.40 metres (Assessment Report 21136).

In 1985 and 1987, West-Mar Resources Ltd. completed programs of rock, silt and soil sampling on the area. In 1991, the area was prospected by K.E. Hicks.
