Platinum-group minerals and gold in Arsenic-rich ore at

Platinum-group minerals (PGM) and native gold are reported in association with gersdorffite ± nickeline from the Thompson mine, Thompson Nickel Belt, Manitoba, Canada. Four PGM-gold-bearing ore types are distinguished on the basis of mineral assemblages and host rocks: I. Irarsite in massive Ni sulphide ore hosted by metapelite; II. Gold, sudburyite, testibiopalladite-antimonian michenerite
