Molybdenum showings occur on the steep west side of the Clearwater River, 9 kilometres north of Clearwater in granitic rocks near the eastern edge of the Cretaceous Raft batholith. Molybdenite occurs as sparse flakes in felsite dikes, small rosettes in granodiorite, smears along fracture planes, and are also associated with a set of quartz veins which strike north 300 to 310 degrees and dip 30 to 55 degrees southwest.
