The Intersection Mountain zinc showing is located approximately 180 kilometres east of the town of Prince George and approximately 58 kilometres north of the town of McBride. The showing is less than 2 kilometres west of the British Columbia–Alberta border, in the Cariboo Mining Division, and is 2 kilometres south of the Intersection Mountain showing (MINFILE 093H 134).
The region is underlain by an assemblage of sedimentary rocks that were deposited in a continental shelf environment along the western margin of Ancestral North America. This clastic and carbonate rock sequence ranges in age from Hadrynian to Upper Cretaceous and now lies within the Foreland tectonostratigraphic division of the Canadian Cordillera. Folds and southwest-dipping, northeast-directed thrust faults are the dominant structures of the region.
Massive sulphide mineralization, that is apparently stratiform in nature, in fine-grained sandstones of the Permian Mowitch Formation.
Near Intersection Mountain, a gossanous zone, approximately 6 metres thick and 20 metres in strike length, occurs in a stratigraphic position that should be occupied by Mowitch strata. In the same area, pieces of dark, bituminous sandstone containing up to 40 per cent pyrite were found in float beneath Mowitch outcrops. Samples of pyrite-rich sandstones contain anomalous concentrations of zinc, up to 0.189 per cent (Fieldwork 1991, pages 65-82).
