Can you help make this a better article? What good localities have we missed? Can you supply pictures of better specimens than those we show here? Can you give us more and better information about the specimens from these localities? Can you supply better geological or historical information on these localities?

A pyroxenoid, related to rhodonite and ferrobustamite. A relatively uncommon mineral found in some metamorphosed manganese deposits, usually massive, and an occaisional lapidary material. The best specimens have arguably come from either the Broken Hill or Franklin mines, but few come out from either area these days.

Bustamite has been found in several mines in the Broken Hill district, most notably the North mine, but also the ZC and NBHC mines (see below). It is not always easy to confirm the precise provenance however. Specimens were locally abundant and in good large crystals. Most specimens came out in the 1960's and 70's; they are now becoming rare. Most occured as somewhat rounded, pink to brown prismatic crystals in calcite with hedenbergite, galena and sphalerite. Some was quite fibrous, and pale pink to white in colour, in late stage vughs.

Bustamite is fairly uncommon for the Kalahari district, but some massive pink material was suitable for lapidary purposes.

This is the type locality, and produced some of the best specimens (arguably equal to those from Broken Hill).
