These included baumhauerite
, freieslebenite, livingstonite and meneghinite, as well as some familiar species like proustite.
Assemblages include: pyrite-hematite-realgar associated with high-silver mineralization consisting of a complex association which includes gratonite, baumhauerite, aramayoite, "waxy" sphalerite, and galena (Ward, 1961); and alunite-native sulfur rug fillings in enargite-pyrite pipes (Cerro de Pasco Corporation, 1950).

The mix of species is somewhat different, however, including such minerals as boulangerite, zinkenite, guettardite, robinsonite, baumhauerite, bindheimite and bournonite which are rarer or entirely absent at Carrara.
A black, metallic, acicular crystal removed from a specimen Collected at the Pitone quarry was found probably to be baumhauerite.
