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-(Fe) rims (AM 73.439 ).
