Joanneumite, confirmed as a new mineral in 2012, is the first recognized isocyanurate mineral, with the formula Cu(C₃N₃O₃H₂)₂(NH₃)₂.^{[4] [5]} It is also an ammine-containing mineral, a feature shared with ammineite, chanabayaite and shilovite.^{[6] [7] [8]} All the minerals are very rare and were found in a guano deposit in Pabellón de Pica, Chile.^[9]
