Maucherite occurs in nickel-cobalt
hydrothermal veins with other nickel arsenides and sulphides
At the Cobalt area, Cobalt-Gowganda region, Timiskaming District, Ontario, Canada, maucherite is associated with nickeline, rammelsbergite and pararammelsbergite in nickel-cobalt-silver deposits (AM 58.203-210).
At the Orford nickel mine, St-Denis-de-Brompton, Le Val-Saint-François RCM, Estrie, Quebec, Canada, maucherite is associated with millerite, uvarovite, pyroxene and calcite (HOM).
At the type locality, Eisleben, Mansfeld Basin, Saxony-Anhalt, Germany, maucherite is associated with nickeline, rammelsbergite, pararammelsbergite, nickeline, nickelskutterudite and chalcopyrite in nickel-cobalt-silver deposits (AM 58.203-210, HOM).
At the Bou Azzer mining district, Drâa-Tafilalet Region, Morocco, sometimes tiny crystals of maucherite appear on masses of nickeline (Minrec 38.5.384).
