Pasavaite occurs as subhedral inclusions (<20 urn) in polarite from a massive Cu-Ni ore from the Talnakh deposit in the Noril'sk-Talnakh mining camp, Taimyr autonomous District, Russia. The grains of polarite are enclosed in chalcopyrite-pentlandite and rimmed by Au-Ag phases and galena. All physical properties except chemistry were determined using synthetic material. Pasavaite is brittle with a weak {001} cleavage, and a Mohs hardness = 2. Measured and calculated densities are 9.9 and 10.18, respectively.
