The Car occurrence is located about 9 kilometres northeast of Mount Carruthers, just south of Carruthers Pass (Property File - Car Claims Compilation Map, Interior Syndicate, 1973).

The showing is hosted in Upper Triassic Dewar Formation (Takla Group) tuffs, sandstones and argillites. The Dewar Formation in this area is bounded to the southwest by the northwest trending Quenada thrust fault and to the northeast by the north-northwest trending Ingenika fault. The claims are predominantly underlain by argillites and fine- grained diorites. The contact between these rocks forms a pyritic zone. Galena and pyrite occur in widely separated and discontinuous quartz veins that range from 0.64 to 5.1 centimetres in width. The host rocks commonly contain up to 10 per cent pyrrhotite (Assessment Report 4879). High silver values are reported to be associated with the galena (Assessment Report 4879).

Approximately 650 metres to the southwest, two veins contain chalcopyrite, galena, sphalerite, limonite and banded crystalline quartz. The veins are 5.1 and 3.8 centimetres wide and are hosted in a gabbroic dyke approximately 30 metres wide. This dyke intrudes green tuffs. A sample from the widest vein assayed 0.34 gram per tonne gold, 327.42 grams per tonne silver, 0.82 per cent copper, 7.15 per cent lead and 1 per cent zinc (Geological Survey of Canada Memoir 251 pages 63).

A small hornblende-diorite stock occurs to the southwest of the Car showing. It is medium grained and appears to have induced the formation of quartz veins plus/minus arsenopyrite, chalcopyrite, sphalerite, and galena which occur in the Dewar Formation rocks to the north of the intrusion. Disseminated pyrite or pyrrhotite is common as well as along fracture fillings and bedding planes in sedimentary rocks and locally in igneous rocks. Concentrations up to 20 per cent have been observed generally within black shale where pyrite/pyrrhotite occurs locally as pods or beds.

WORK HISTORY

The CAR 1-64 claims were staked by Interior Syndicate in the spring of 1973, over known minor mineral occurrences followed up by by geological and geochemical examinations of the property (Assessment Report 4879).

In 1998, based on the results of the 1997 BC regional geochemical survey, Phelps Dodge Corp. of Canada Ltd. conducted a reconnaissance soil and stream sediment sampling program of the anomalous drainages. From the results of the reconnaissance sampling, two 20-unit claim blocks were staked by Phelps Dodge, later that year - Pass 1 and Pass 2.

Phelps Dodge performed reconnaissance prospecting with rock, silt and soil sampling in 1998 to evaluate the copper potential of the property. Preliminary prospecting identified a pyritic zone surrounding a diorite intrusion with abundant quartz veins containing pyrrhotite plus/minus galena plus/minus chalcopyrite plus/minus sphalerite plus/minus arsenopyrite. Anomalous concentrations of copper, zinc, silver, cobalt, arsenic, antimony, bismuth and selenium were delineated in soils from several cirque valleys on both Pass 1 and 2. Further prospecting in 1999, discovered a massive sulphide lens on the Pass 2 claim and subsequently the Pass 3 claim was staked to cover possible strike extents to the massive sulphide horizon. Sampling and mapping was completed by Phelps Dodge in the area around the Car showing (Assessment Report 26094).

Work in 2000 by Phelps Dodge consisted of geochemical sampling, prospecting along with 0.9 kilometre of ground electromagnetic (VLF) and magnetic surveying. Prospecting resulted in the discovery of several small chalcopyrite and chalcocite veins which yielded assay values up to 1.4 per cent, 13.6 grams per tonne silver and anomalous gold, located on the east side (central) or the Pass 3 claim (see new MINFILE) (Assessment Report 26388). In addition, geochemical soil sampling on the Pass 3 claims collected several soil samples that were anomalous in copper, zinc and silver. Geophysical work proved to be unsuccessful in delineating any further extents to the massive sulphide lens found during the 1999 field season. A total of 17 rock samples and 23 soils samples were collected in 2000.
