Polished section petrography subsequently identified the sulphide species as Vaesite (NiS2), a nickel mineral which may also contain cobalt4.
The vaesite fragments are alluvial in nature and therefore not necessarily representative of an in-situ nickel sulphide body.
The mineral is generally associated with masses of gray siegenite and black vaesite. Massive veins of siegenite have resulted from the replacement of vaesite or cattierite veins.

Vaesite was reported in microscopic grains at the W.
(1967) Early diagenetic framboidal pyrite, bravoite, and vaesite in the Cave in Rock fluorspar district, southern Illinois.
