'''Itelmenite''' is a rare [sulfate](/source/sulfate) mineral with the formula Na<sub>4</sub>Mg<sub>3</sub>Cu<sub>3</sub>(SO<sub>4</sub>)<sub>8</sub>. It is one of many [fumarolic mineral](/source/fumarolic_mineral)s discovered on the [Tolbachik](/source/Tolbachik) volcano.<ref name=N>Nazarchuk, E.V., Siidra, O.I., Agakhanov, A.A., Lukina, E.A., Avdontseva, E.Y., Vergasova, L.P., Filatov, S.K., and Karpov, G.A., 2015.
