Miargyrite is a silver antimony sulfosalt (Moëlo et al., 2008). The mineral name combines Greek roots meios, for less, with argyros, for silver; miargyrite has a lower silver content than other well-known ores (i.e. acanthite, proustite and pyrargyrite). Miargyrite was among the first species to undergo crystal structure solution (Hoffman, 1938), later refined by Knowles (1964). Shannon (1929) described miargyrite morphology from the Randsburg.

Miargyrite here forms complex stubby crystals to 1.5 mm. The crystals are metallic and nearly black, contrasting with associated quartz. The heavy metallic matrix appears to be massive miargyrite.
