The King Fraction (Lot 11241) is located on the east side of Williams Creek, 2 kilometres south of the town of Barkerville.
The showing lies within the Barkerville Terrane of the Omineca Belt. The Barkerville Terrane is in thrust contact with Triassic Quesnel Terrane rocks to the west and Hadrynian to Lower Paleozoic Cariboo Terrane rocks to the east. The Barkerville Terrane in this region is underlain by the dominantly metasedimentary rocks of the Hadrynian to Lower Paleozoic Snowshoe Group. In this area the Snowshoe Group comprises limestone, phyllite and quartzite. These rocks have been regionally metamorphosed to greenschist facies.
The showing comprises mineralized quartz veins cutting metasiltstones, phyllites and phyllitic quartzites of the Upper Proterozoic-Paleozoic Snowshoe Group. Although Williams Creek has a history of placer and lode gold exploration dating from the 1860s, the veins comprising the King showing are documented by a 1983 exploration program covering the King Fraction Reverted Crown grant mineral claim. These include a galena-bearing quartz vein from within the King Fraction mineral claim, and a pyrite-rich quartz vein marked by an old adit 250 metres to the northeast, just outside the boundary of the King Fraction claim. A grab sample from the galena-bearing vein yielded 27.43 grams per tonne silver and 2.96 per cent lead, but only a trace of gold. A sample of pyrite-rich vein material from the adit dump analyzed 7.68 grams per tonne gold, 23.31 grams per tonne silver and 0.33 per cent lead (Assessment Report 11489).
In 1981, Geo-Ex Resources Ltd. optioned the Mount Proserpine property from Mssrs. R. Barclay and B. Price, conducting a percussion drill program in the vicinity of the Warspite adit (093H 048) and some reconnaissance geochemical work on two outlying claims, the Pin Money (Lot 10420, 093H 147) and King Fraction. In 1983, the Pin Money and King Fraction mineral claims were owned by Normine Resources Ltd. and work done in the same year consisted of a 2-day program of geological mapping and sampling, and geological reconnaissance and prospecting on the adjoining ground.
