Formula:
Cu3BiS3
Dimorph of:
Co-described with UM1993-17-S:CuFePb.
Chemical composition identical to that of wittichenite, but optical properties differ; therefore suggested to be a dimorph of wittichenite (Akande & Mücke, 1993).
Size of the individuals is likely 45 x 50 microns. As intergrowths with bornite, enargite, tennantite, and chalcopyrite.
