The Loumark (King George) occurrence is located near the western side of the Kettle River and approximately 1.5 kilometre north of its confluence with Bruer Creek. This area is located approximately 31 kilometres northeast of Big White Mountain. All mineralization lying between the Kettle River and Bruer Creek, and within 2 kilometres to the north of their confluence are grouped under this occurrence.
The area is primarily underlain by quartz diorite and granite of the Jurassic Nelson Plutonic Suite(?) with isolated outcrops of undivided metamorphic rocks of the Proterozoic to Paleozoic Shuswap Assemblage and basaltic volcanic rocks of the Miocene to Pliocene Chilcotin Group.
The number of mineral showings included in this occurrence is unclear. A Geological Survey of Canada Open File describes two occurrences: the East Loumark (King George?) is a gold-silver-lead occurrence in quartz veins on the west side of the Kettle River, while the West Loumark, approximately 750 metres to the west, is a gold-silver-lead-zinc occurrence in quartz veins on the east side of Bruer Creek. Both are hosted by a quartz diorite intrusion. Another description of the site, in which it is simply referred to as Loumark, describes gold and silver mineralization occurring in disseminated and streaky sulphides (pyrite, galena, chalcopyrite, and arsenopyrite) in quartz veins (Geology, Exploration and Mining in British Columbia 1974, page 66). The coordinates of this site plot approximately 1 kilometre to the south of the East Loumark occurrence. Other workings are reported north of the bridge crossing Bruer Creek, on its west bank.
The King George (East Loumark?) occurrence is reported to consist of three quartz veins, up to 2 metres wide, cutting an intrusive and hosting pyrite, galena, chalcopyrite, sphalerite, bornite and arsenopyrite mineralization. The veins strike 10 to 20 degrees and dip 40 to 60 degrees west. In 1988, five grab samples from the King George discovery pit yielded from 1.33 to 52.98 grams per tonne gold (Assessment Report 29603). In 2007, rock sampling from the former workings yielded up to 52.58 grams per tonne gold and greater than 100 grams per tonne silver (Assessment Report 29603). In 2009, a rock sample (No.6) assayed 4.02 grams per tonne gold and greater than 100 grams per tonne silver (Assessment Report 31111).
In 1978, a sample (128) of granodiorite from the south west corner of the WIN 16 claim assayed 0.20 per cent zinc (Assessment Report 07160E). This claim appears to be located just east of the Kettle River.
Two shafts, 15 metres deep and 8 metres apart, and a pit are reported from the 1930’s on the King George occurrence, located on the west side of the Kettle River. In 1974, Woodman Enterprises Ltd. carried out 15 metres of underground work including underground geological mapping, 76 metres of trenching and 52 metres of diamond drilling in three holes. None of this work was filed for assessment and the results are unknown. In 1978, Kelvin Energy completed a regional program of geochemical sampling and airborne geophysical surveys on the area as the Win 14-16 claims. In 1988, Barnes Creek Minerals located and sampled the former King George (East Loumark?) discovery pit. During 2007 through 2013, Hard Rock Gold completed programs of prospecting, rock, soil and heavy mineral sampling and an 8.7 line-kilometre ground magnetic survey on the area.
