Vymazalováite was approved in 2016, but to date (September 2022) it has been reported only from the type locality.
Localities
At the type locality, the Komsomol'skii mine, Talnakh Cu-Ni Deposit, Noril'sk, Putoran Plateau, Taimyr Peninsula,
Taymyrskiy Autonomous Okrug, Krasnoyarsk Krai, Russia, vymazalováite forms small (from a few μm to 20–35 µm)
inclusions or euhedral grains in intergrowths of polarite,
sobolevskite, acanthite and
unnamed (Pd,Ag)5BiS2 in aggregates (up to ~200 µm) in galena,
and rarely in chalcopyrite. It occurs with
telargpalite, cooperite,
braggite, vysotskite,
sopcheite, stibiopalladinite,
sobolevskite, moncheite,
kotulskite, malyshevite,
insizwaite, gold-bearing
silver and kravtsovite in
association with pyrite,
chalcopyrite and galena in
vein-disseminated mineralisation in skarn rocks
(MM 82.367-373).
