Formula:
Pt(Rh,Ir)CuS4
Most likely identical to (synonymous with) ezochiite.
Comparable (or identical?) to 'UM1980-11-S:CuIrPtRh'. Possibly isostructural with malanite? Compare cuprorhodsite.
As subhedral inclusions, 15 x 15 to 15 x 20 microns in size, with rounded, "hexagonal" outlines, within a Pt-Fe alloy nugget.
