Introduction: zincite is a rare secondary mineral named in 1845 for its composition. Zincite has been reported as occurring in a variety of geological settings, from primary, metamorphosed stratiform zinc orebodies to secondary, oxidized zinc-rich ore deposits and as a product of volcanism. Crystals are rare, with the exception of man-made smelter products.
Occurrence in Wales: the presence of zincite in Wales is highly doubtful. Andrew (1910) listed zincite as, one of the minerals in the Cefn Coch Lode in the Dolgellau Gold-Belt. No specimens are known and this species has never before, or since been discovered in the British Isles.
- Cefn Coch Lode, Dolgellau Gold-Belt, Gwynedd: Andrew (1910) describes the Cefn Coch Lode as usually containing quartz, blende (sphalerite) and galena, but also containing chalcopyrite, pyrite, zincite and gold.
