The Kamloops occurrence is located at 1326 metres elevation 7.5 kilometres southeast of Baldy Mountain, in the former historic Camp McKinney. The Kamloops Reverted Crown grant lies between the Sailor (Lot 766) and Minnie-Ha-Ha (Lot 680) Reverted Crown grants of the McKinney camp. The camp lies 9 kilometres north-northwest of Bridesville, British Columbia.

The Camp McKinney area is underlain by interbanded and intergrading Carboniferous to Permian Anarchist Group metamorphosed sediments and volcanics. The group is mainly sedimentary and consists of greenstone, locally calcareous, altered quartzite and argillaceous quartzite, greywacke, limestone and locally micaceous quartzite and calcareous biotite schist. The minor volcanics are described as mainly altered andesitic and basaltic flows.

Granite and granodiorite of the Middle Jurassic Nelson intrusions have intruded the Anarchist Group to the west and south as small stocks and plugs. Along the contacts of these intrusions the Anarchist rocks have been deformed and hydrothermally altered. Younger dikes of felsic and mafic composition intrude both stratified and granitic rocks and may have been associated with faults related to these granitic intrusions.

The major regional structural feature in the vicinity of the Cariboo-Amelia occurrence (082ESW020) is a northeast trending fault zone 5 kilometres to the east. The fault follows Conkle Creek, Conkle Lake and Jolly Creek.

Faulting in the Cariboo-Amelia mine area is postmineral and widespread. Major east dipping, low angle thrust faults in the central portion of the mine have displaced the hangingwall to the northwest by about 122 metres. An east-dipping fault has also moved the hangingwall south by about 91 metres. The complexly faulted and folded rocks are predominantly northwest striking and steeply to moderately northeast dipping.

The Kamloops occurrence is hosted in banded greenstone of the Anarchist Group dipping flatly northward. Considerable quartz was reported in a dump near the shaft.

Development work began on the Kamloops occurrence pre-1897, as by this time it was reported that a 30-metre shaft, with 23 metres of drifting, was sunk on a quartz vein (Minister of Mines Annual Report 1901, page 1151). A second 12-metre shaft is located 24 metres southwest of the main shaft. The shaft was sunk in quartzite but little quartz vein or mineralization was observed. Two other prospecting shafts were also commenced and were 3.6 and 4.6 metres deep, respectively. At this time the Crown-granted claim was owned by J. Moran and development was carried out by the McKinney-Kamloops Company until 1900. In 1940, the property was owned by J.L. Grant.

The vein intersected in the two shafts is considered to be the eastern extension of the Sailor vein (082ESW045) and the faulted western extension of the Minnie-Ha-Ha vein (082ESW046). Refer to these two occurrences for further details on the vein geology and mineralization.
