Bojarite is a relatively new mineral, approved in 2020 and to date (May 2022) reported only from the type locality.

Localities

At the type locality, Pabellón de Pica, Chanabaya, Iquique Province, Tarapacá, Chile, the triazolate mineral bojarite is found in a guano deposit. A triazolate mineral has a structure featuring 5-membered rings with 2 carbon and 3 nitrogen atoms, giving (N3C2H2) groups in the formula). Associated minerals include salammoniac, halite, nitratine and belloite. Bojarite occurs as blue fine-grained porous aggregates up to 1 mm × 3 mm × 5 mm combined typically in interrupted earthy crusts (MM 84.6.913-920).
