The Copper King showing is located 1500 metres southwest of Olsen Lake in the vicinity of Theodosia River. The geology of the area consists of granodiorites of the Juro-Cretaceous Coast Plutonic Complex within which are contained small northwest trending remnants of metamorphosed country rock.
The showing is skarn-hosted and consists of two mineralized zones, the Zinc Zone and the Magnetite-Copper Zone. The Zinc Zone, composed of sphalerite and minor galena, is at the contact between granodiorite and limestone (now a skarn). The Magnetite-Copper Zone, composed of magnetite and associated chalcopyrite, occurs at the con- tact of limestone with greenstone. The two zones are separated by a distance of 80 metres. The mineralization within both zones has a northwest strike and dips near vertical.
A grab sample in 1926 from the dump at the mouth of the adit in the Zinc Zone assayed 17.0 per cent zinc, 2.0 per cent copper and 82.27 grams per tonne silver. Gold was measurable only in trace amounts and lead was unmeasurable (Minister of Mines Annual Report 1926, page 310).
A grab sample, also in 1926 from the dump of the glory hole in the Magnetite-Copper Zone assayed 46.6 per cent iron, 5.7 per cent copper, 68.56 grams per tonne silver and trace gold (Minister of Mines Annual Report 1926, page 310).
Work History
The area was first explored and staked in 1898. During 1925 through 1928, Revenue Mining Co. Ltd. acquired the claims and completed three open-cuts, a 12.2-metre long adit and 2.4 metre winze.
In 1961, Delhi Pacific Minerals and Norco Resources Ltd. completed 12 drill holes, totalling 1036.3 metres, and a magnetometer survey. The property was dropped in the 1970s.
In 2014, Maccabi Ventures Inc. conducted a minor program of geological mapping and rock sampling.
