The KV (Calendonia) occurrence is located adjacent to the east side of the original Caledonia (L.973) Crown grant, on an east- to northeast-facing slope, west of the Granby River and approximately 6.5 kilometres northwest of the community of Grand Forks.
The area is underlain by argillite and chert, probably of the Carboniferous to Permian Attwood Group. Intrusions of diorite are reported and are probably related to the Jurassic to Cretaceous Nelson Intrusions. Andesite was reported to cover the remainder of the claim area, with occasional limestone windows, with associated talc carbonaceous rock near the sediments. Weakly disseminated pyrite occurs in the andesite but most sulphides occur in the sediments and comprise pyrite, pyrrhotite and copper sulphides (probably chalcopyrite).
The Caledonia claim is reported to be an area of poor outcrop that is underlain by Triassic Brooklyn Formation greenstone. Exploration pits have exposed sulphide mineralization in separate fracture and skarn zones. In 1991, an old exploration pit excavated on skarn mineralization in light-grey, rusty carbonates was observed. Several small (0.5 metre), copper-bearing, massive sulphide lenses are present in a limestone horizon within the Brooklyn greenstone. Outcrop exposure is limited to the extent of the pit (100 square metres). Trenching has exposed a narrow (1 to 2 metres wide), east (110 degrees)- trending fracture zone 50 metres southwest of the old pit. Weak pyrite and chalcopyrite mineralization is present along moderate to steep (65 degree) south-dipping fractures in the fine-grained greenstone.
In 1991, a sample of skarn material from a historical pit assayed 0.75 per cent copper (Assessment Report 22263).
In 2005, a sample (12319) from a pit, referred to as Brown’s pit and exposing chalcopyrite veins and pyritic quartz veins, assayed 0.611 per cent copper, 0.351 per cent antimony and 0.313 gram per tonne gold, whereas a dump sample (12316) from the pit yielded 0.366 per cent copper and 18.00 grams per tonne gold (Sookochoff Consultants [2021-03-15]: Technical Report on the CBC Property for Belmont Resources Inc.).
To the east of the KV (Caledonia) occurrence and on the former Goat Mountain group of claims several historical pits are reported to exposed minor occurrences of chalcopyrite and pyrite.
Work History
B.C. Minister of Mines Annual Reports show that the Caledonia claim was Crown-granted as Lot 973 in 1899.
In 1969 and 1970, Bayland Mines Ltd, completed programs of geological mapping and ground magnetic, electromagnetic and induced polarization surveys on the area as the Caledonia and Goat Mountain groups of claims. Also in 1970, The Granby Mining Company Ltd. completed a ground magnetic and induced polarization survey on the area as the KV claims.
In 1983, Kettle River Resources Ltd. completed a program of geological mapping on the area as the RB property. In 1985, Noranda Mining and Exploration Inc. completed a program of geological mapping, soil sampling and ground magnetic and electromagnetic surveys on the area as the PAC and RB claims of the Eagle 85 group.
In 1990. Mr. W.G. Hallauer successfully bid on the Caledonia claim as a Crown-granted two-post claim (Record No. 5675). In 1991, prospecting was completed over the claim and copper mineralization exposed in two pits was sampled.
During 2004 through 2006, the area was prospected as the CB Chance property.
During 2008 through 2012, Grizzly Discoveries Inc. completed programs of geochemical sampling, geological mapping and ground geophysical surveys on the area as the Attwood area of the Greenwood property.
