From Alfredo Petrov:
MIHARAITE (mihara-koh)
- Okayama: The type locality of miharaite, a rare Cu-Fe-Pb-Bi sulphide, is the Honpi deposit at the Mihara mine, where it forms microscopic intergrowths with chalcopyrite and galena, occasionally also wittichenite (from which it is indistinguishable by ore microscopy), as grains to a few hundredths of a mm across as inclusions in bornite grains in a bornite-rich skarn. Only visible in polished section, where it displays a pale grey to greyish white colour. Also found at the Imooka mine.
