Uraninite Crystal — Chaput-Payne Mine, Quebec, Canada

Quebec's uranium mineralogy is less widely represented in the collector market than Ontario's Bancroft district, which makes locality-labelled specimens from documented Quebec occurrences particularly worthwhile for systematic Canadian collectors. The Chaput-Payne mine is a pegmatite-hosted uranium occurrence consistent with the broader Grenvillian and Precambrian geological framework that produces uranium deposits across the Canadian Shield. Uraninite from this locality occurs in the heavy, dense form characteristic of the species — uranium dioxide, UO₂, with a theoretical uranium content of approximately 88% — and primary crystals retain the cubic to octahedral habit typical of high-temperature pegmatite crystallization. This specimen presents a discrete uraninite crystal from the Chaput-Payne mine, a Canadian locality outside the well-trodden Bancroft camp. For collectors seeking provincial breadth within Canadian uranium mineralogy, or those specifically documenting Quebec occurrences, this piece fills a gap that is not easily sourced.
