Thalhammerite is a relatively new mineral, approved in 2018. Associated minerals include braggite, vysotskite, stibiopalladinite, telargpalite, sobolevskite, kotulskite, sopcheite, moncheite, malyshevite, insizwaite, acanthite, gold-bearing silver, kravtsovite, vymazalováite, galena, chalcopyrite, bornite, millerite and pyrite (HOM).

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, thalhammerite occurs in vein-disseminated galena-pyrite-chalcopyrite and millerite-bornite-chalcopyrite deposits hosted by diopside-hydrogrossular metasomatites developed in diopside-monticellite skarn. It occurs as tiny inclusions, from a few μm up to about 40–50 μm, intergrown in pyrite, chalcopyrite, and also in bornite. Other associated minerals include millerite (HOM, Mindat).

At the Southern Kievey Fedorovo–Pana layered intrusion, Fedorovo-Pansky massif, Murmansk Oblast, Russia, thalhammerite occurs in platinum group element ores in a layered intrusive (HOM).
