Arsenopyrite: Mineral information, data and localities.
Arsenopyrite Group. For possible Ni-analogue see Unnamed (Ni,Fe,Co)AsS; see also Unnamed (Ni Arsenide Sulphide).Arsenopyrite is closely related to alloclasite, but is not an exact analogue, because of different As-S and S-As ordering. Arsenopyrite may contain up to about 9 wt.% Co; with higher Co contents, glaucodot will appear as a separate phase (Gammon, 1966).

What Does Gold Ore Look Like? | Sciencing
For example, pyrite and arsenopyrite are carriers of invisible quantities of submicroscopic gold. Another obstacle to seeing gold in gold ore occurs when gold entwines with other metals within the ore. Such finely distributed particles of gold only become visible after tests reveal the ore is worthy of processing.
