The Dave showing area south of Bose Lake is underlain by Guichon variety granodiorite of the Late Triassic-Middle Jurassic Guichon Creek batholith. In 1963, Huestis Mining Corporation Ltd. conducted geochemical and ground magnetometer surveying, an induced polarization survey and 572 metres of diamond drilling in six holes, of which two did not reach bedrock. A north striking chloritic fault had been trenched exposing small amounts of disseminated bornite and chalcopyrite. Three drillholes intersected the fault and mineralization at depth.
