The Belle showing is located east of Taghum, approximately 8 kilometres west of Nelson.

The area is underlain by Jurassic pseudodiorite and pyroxenite of unknown affinity. Late to Middle Jurassic Nelson Intrusions consisting mainly of non-porphyritic granite and granodiorite occur to the north. Locally, the rocks comprise coarse pegmatite.

Visible mineralization consisting of disseminated molybdenite and pyrite is found within fractures and quartz veins usually associated with the pegmatite.
