Formula:

(Cu,Zn,Fe)_3.23(As,Sb)_0.82S₃

simplified as Cu₃AsS₃

Compositionally close to tennantite, but optically different. Co-described with UM2001-14-S:AsCuSbZn.

Possibly the As analogue of skinnerite (assuming monoclinic symmetry and ideal stoichiometry).

Associates: chlorite group, "sericite", quartz, pyrite, chalcopyrite.

Opaque grains, 2 × 6 μm in size. EPMA data (wt.%):

Cu 52.36
Zn 2.39
Fe 1.78
As 16.64
Sb 0.74
S 27.01

total 100.92

This corresponds to (Cu_2.97Zn_0.13Fe_0.11)_Σ3.21(As_0.79Sb_0.02)_Σ0.81S_2.98.
