Arsenoveszelyite is a new mineral, approved in 2021 and first published in 2025. To date (January 2026) it has been reported only from the type locality.

Localities

At the type locality, the Dongchuan Cu Mine, Sanguozhuang, Dongchuan District, Kunming, Yunnan, China, arsenoveszelyite is one of a number of new (in 2025) secondary minerals discovered here, the others being dongchuanite, cuprodongchuanite, zheshengite, cuprozheshengite and qiumingite. Mineralisation is hosted within a stratiform copper deposit and its secondary assemblage (AM 111.169).
Arsenoveszelyite occurs as radiating aggregates or as individual lamellar crystals; it is a supergene mineral from the sediment-hosted Zn–Pb–Cu deposit, and is associated with azurite and hemimorphite (Mindat).
