Andy Tindle: Ajoite is listed on MinDat from England, Devon, Tavistock District, Tavistock Hamlets, New East Wheal Russell (South Wheal Crebor). No reference is given, but almost certainly the source is the British Micromount Society database. An XRD examination of supposed ajoite from this location was inconclusive and ajoite was not confirmed. ex Bernie and Margaret Day Collection
