Localities

The Sakattilampi, Viiankiaapa mire area, Sodankylä, Lapland, Finland, nickel - copper - platinum group element deposit comprises massive, disseminated, and vein sulphide mineralisation. Although not embodying platinum group minerals, the number of bismuth-tellurides and silver minerals intergrown with platinum group mineral aggregates is remarkable. The bismuth-tellurides include kawazulite, pilsenite and tsumoite (CM 59.1485-1510).

At the Koronouda occurrence, Kilkis, Kilkis, Central Macedonia, Greece, pilsenite is associated with argentopentlandite, hessite and argentotetrahedrite (HOM).

At the type locality, Nagybörzsöny, Szob District, Pest County, Hungary, pilsenite is associated with hessite, joséite and bismuthinite (HOM).

At the Sylvanite Mining District, Hidalgo County, New Mexico, USA, pilsenite is associated with tsumoite (HOM).
