    Precious Metals (Pt-Pd-Au-Ag) in Three Copper-Nickel Deposits in the Duluth Complex
    (University of Minnesota Duluth, 1989-11) Hauck, Steven A
    The research work on the precious metals in the three copper-nickel deposits centered on: 1) defining the lateral and vertical extent of the precious metals; and 2) the controls on mineralization, e.g., lithology, structure, etc. While these objectives were the same for each deposit, the methods of investigation at each deposit were dependent upon the amount and quality of previous data available.
