The area of the Mist occurrence is underlain by undifferentiated sediments and volcanics of the Upper Triassic Stuhini Group. This group consists of mafic to intermediate volcanics, chert and siltstone. These rocks are intruded by felsic and dioritic dikes up to 150 metres in width. Just south of the occurrence a narrow exposure of Carboniferous or Permian schists and gneisses is truncated at its south end by a Tertiary-Cretaceous quartz-monzonite batholith.

A local zone of quartz veining within the volcanics and sediments contains traces of pyrite, pyrrhotite and chalcopyrite. Assays from this showing average 0.01 per cent copper and up to 0.55 gram per tonne gold. Samples of siltstone float containing chalcopyrite assayed 0.184 per cent copper, 13.03 grams per tonne silver and 0.2 gram per tonne gold.

The JR zone of Prolific Resources/Skeena Resources 'found' in 1988 may in fact be a rediscovery of the Mist showings. Toward the west, on the MJ 15 claim, the JR showing was discovered in 1988 by Prolific Resources. This sulphide-rich sheared andesite is mineralized over a 5 to 7 metre width, striking at 050 degrees. It is exposed for a distance of 15 metres. One of the initial grab samples (JR-14) assayed 2.02 grams per tonne gold, 34.97 grams per tonne silver, and 7.88 per cent copper (Assessment Report 18134). Systematic sampling across this zone resulted in the delineation of high copper and silver values but only geochemically anomalous gold values. Sample CS-09 from the brecciated shear zone contained 20 centimetres intense malachite/azurite/limonite staining, 5 per cent chalcopyrite, 1 per cent pyrite as blebs in quartz-calcite matrix which grade to massive sulphide. This 0.5 metre chip sample assayed 0.08 gram per tonne gold and 16.60 grams per tonne silver (Assessment Report 18134).

Work History

In 1980 and 1981, Du Pont of Canada Exploration Limited collected a total of 34 stream sediment 176 soil, 36 rock and 21 stream sediment samples were obtained from the Mist 1 and 2 claims and the Mist occurrence was documented (Assessment Report 9218, 10476.

Assessment Report 18134, 21883 (Map 1) shows that the area of the Mist showing was prospected by International Phoenix Energy Corp and by Skeena Resources Ltd in 1988 and/or 1991 as the MJ claims.
