Invisible Gold IdentificationAssaying Microscopy

Refractory gold does not leach which means that it is not exposed at the mineral surfaces. It can be present as fine grains in another mineral or in solid solution in the mineral. By definition it is not chemically bound to the host mineral. On rarer occasions the gold is in a true mineral often a telluride like Calverite or AuTe2.
