Aikinite is an uncommon bismuth-bearing mineral in hydrothermal veins, associated with gold,
enargite, chalcopyrite and
The type locality is the Berezovsk Deposit, Beryozovsky, Sverdlovsk Oblast, Russia.
The Two Mile and Three Mile deposits, Paddy's River, Paddys River District, Australian Capital Territory, Australia, are skarn deposits at the contact between granodiorite and volcanic rocks. Aikinite is a primary sulphosalt that occurs in minor amounts as small grains and aggregates intergrown with galena close to adjacent chalcopyrite and within chalcopyrite and associated gangue in copper-rich material (AJM 22.1.38).
At the Carrock mine, Caldbeck Fells, Cumbria, England, UK, aikinite has been found as minute crystals in quartz stringers in greisen (C&S).
