Argentotennantite-(Zn) is a very rare mineral. Common associates include ankerite,
stibnite, tennantite and
At the Mogul Mine, Silvermines District, County Tipperary, Munster, Ireland, argentotennantite occurs in a stratiform lead-zinc orebody associated with geocronite, proustite – pyrargyrite and galena (HOM).
At the type locality, the Kvartsitovje Gorki gold deposit, Aksu, Stepnogorsk, Akmola Region, Kazakhstan, argentotennantite occurs in a polymetallic deposit associated with tennantite, tetrahedrite, siderite, stibnite, pyrite, quartz, mercurian gold, galena, ankerite and freibergite (Mindat, HOM). It is often in zoned grains, occurring between tennantite cores and argentotetrahedrite rims (AM 73.439 ).
