The RIV showing is situated on Whipsaw Creek, 13 kilometres southwest of Princeton.

This area in the vicinity of Whipsaw Creek and Kennedy Lake is underlain by calcareous siltstone and sandstone, conglomerate, andesite, andesitic tuff and volcanic breccia of the Upper Triassic Nicola Group.

The showing consists of a highly oxidized zone of brecciation and mineralization in an intensely silicified andesitic to dacitic volcanic. The breccia zone is 45 metres wide and appears to cross the creek. The zone contains veins and stringers of quartz with disseminated pyrite and arsenopyrite. A grab sample containing arsenopyrite assayed 18.5 grams per tonne gold and 2 grams per tonne silver (Minister of Mines Annual Report 1928, page 265). Samples of oxidized pyrite carried no gold.

This deposit was first explored between 1928 and 1931. A magnetometer survey was completed by Control Energy Corporation in 1986. During 2007 through 2009, Canadian international Minerals Inc. examined the area as the Copper Mountain property. Exploration work included programs of limited prospecting and sampling and an airborne magnetometer and electromagnetic survey.
