The Bear Fr. occurrence area is entirely underlain by Bethsaida phase granodiorite of the Early Jurassic-Late Triassic Guichon Creek batholith. A vertical diamond drill-hole (192) is reported to have encountered mostly Skeena variety coarse-grained quartz diorite with varying intensities of argillic and locally intense propylitic alteration. Alteration minerals include sericite, kaolinite, chlorite, epidote, quartz, hematite and limonite. Only trace amounts of chalcopyrite, molybdenite and pyrite were reported. Copper and molybdenum assayed 0.01 and 0.001 per cent respectively over 3 metres (Assessment Report 8829). No surface mineralization is described.

Percussion and diamond drilling to the south and east on Bear 5, 9, 10, 13-18 claims encountered little to no mineralization.
