Capsule Geology

The region is underlain by (?) Hadrynian to Paleozoic Snowshoe Group rocks, which occur within the Barkerville Terrane of south-central British Columbia. These metasedimentary rocks consist primarily of marble, quartzite and phyllite which in the area of the Bon showing (093A 160) comprise the Downey succession (informal name). Metamorphism of the region varies from chlorite grade to sillimanite and higher. The lode gold deposits of the region occur in rocks metamorphosed no higher than greenschist facies.

The Park or Bon showing is underlain by chloritic and sericitic rocks interbedded with siliceous and calcareous members, probably of the Lower Paleozoic Downey succession. Galena-sphalerite-pyrite mineralization occurs in quartz-carbonate veins oriented generally subparallel to the foliation of enclosing phyllitic metasedimentary rocks. The galena and sphalerite are closely associated with high gold and silver values.

Trenching on the east slope of Nugget Mountain, on the Park claims, resulted in an average assay across 14 metres of 0.54 gram per tonne gold, 41.47 grams per tonne silver and 2.01 per cent lead (Property File - Mitchell, J.A., 1970).

Rock chip sampling in 1985 resulted in a best assay of 1098.33 grams per tonne silver and a soil survey returned a high gold value of 6.2 grams per tonne (6200 parts per billion) (Assessment Report 13550).

During 2000 through 2008, Golden Cariboo Resources Ltd. completed programs of prospecting, geological mapping, geochemical (rock, soil, moss and stream sediment) sampling, ground magnetic and self potential surveys, trenching and 60 diamond drill holes, totalling 28,710.0 metres on the area as the Golden Cariboo property. A complete summary of exploration programs can be found at the Cariboo Hudson (MINFILE 093A 091) occurrence.
