The region is underlain by the Upper Triassic to Lower Jurassic Takla Group. The Takla Group has been intruded by Lower Cretaceous granodioritic to quartz monzonitic plutons known as the Naver Intrusions. The Ice showing is underlain by Upper Triassic Takla Group basaltic rocks and part of a Naver Intrusion which has intruded the basalt. Mineralization consists of molybdenite within granodiorite of the intrusion.
