The COLLIER showing is located on the west side of Dear Creek, approximately 6.5 kilometres southwest of the Kettle Valley community of Christian Valley.

The area is underlain by granite and quartz monzonite of the Cretaceous-Tertiary Okanagan Batholith. Unconformably overlying the plutonic rocks are tuffs, flows and related volcaniclastic sediments of the Eocene Marron Formation, Penticton Group. The volcanics are cut by Eocene Coryell syenite and monzonite intrusives and dikes, and younger dacite feeder dikes, correlative with the Marron Formation.

The Miocene-Pliocene Chilcotin Group occurs as isolated, flat- lying rocks consisting of vesicular and massive columnar olivine basalt flows with occasional interformational sediments. A potassium/ argon age of 5.0 plus or minus 0.50 Ma was determined for the basalt (Map 29). Miocene fluvial sediments underlying the basalts are unconsolidated, interbedded arkosic sandstones, siltstones, carbonaceous mudstones, and basal conglomerates. These sediments occur as structurally controlled 'paleochannels', which are host to uranium deposits.

The Collier showing is a radioactive drillhole intersection, approximately 400 metres southwest of the southern end of the FUKI deposit (082ENE015). In 1979, Nissho-Iwai Canada Ltd. carried out a 5 hole diamond-drill program on the COLLIER property for Power Reactor and Nuclear Fuel Development Corporation, of Japan. The westernmost hole C204, intersected 0.017 per cent uranium over 0.35 metre within the sediments (Assessment Report 8105). The other 4 holes were barren. Results of 6 holes drilled in 1971, 500 metres to the northeast, returned low levels of radioactivity except for one hole (BCF 39) with up to 1800 counts per minute (0.06 equivalent uranium) over 1.2 metres (Assessment Report 3135). This drilling represents a portion of the south part of the Fuki deposits.
