Platinum-group elements in ores from the Kalmakyr porphyry Cu-Au-Mo deposit, Uzbekistan: bulk geochemical and laser ablation ICP-MS data

Original language description

We studied primary ore samples from Kalmakyr, a giant Cu-Au-Mo porphyry deposit in eastern Uzbekistan. Disseminated and stockwork type high-grade Cu-Au-Mo mineralization showed average concentrations of 55 ppb Pd, 5.5 ppb Pt, 0.95 ppb Rh, 0.49 ppb Ir, and 4.1 ppm Au (n=8). This type of mineralization is characterized by the presence of pyrite, chalcopyrite, molybdenite and gold. A peak Pd content of 291 ppb was determined in a base-metal rich quartz vein in granodiorite porphyry, which contains galena,sphalerite, chalcopyrite, tetrahedrite and gold. Palladium correlates with Cu, Ag, Se, and S. Mineralogical and laser ablation ICP-MS study confirmed that Pd is homogeneously distributed in chalcopyrite, which contains up to 110 ppm Pd, and tetrahedrite,containing up to 20 ppm Pd. An assessment of the Pd and Pt budget at Kalmakyr showed the potential of approximately 17 t of Pd and 1.7 t of Pt.
