... in the marginal zones of the East Bull Lake and River Valley intrusions near Sudbury and the Portimo intrusion(s) in Finland are also characterized by high ratios from 11 to 18. In summary, one can say that most sulfide-rich Ni-Cu deposits have (Pt + Pd)/(Ni + Cu) (PGE in g/t, Ni and Cu in wt %) ratios of less...
