The Giant Mascot Ni-Cu-PGE deposit is British Columbia's only past-producing nickel mine (1958-1974), having yielded ~ 4.2 Mt of ore grading 0.77% Ni and 0.34% Cu with minor Co, Ag and Au. Intrusive ultramafi c rocks (olivine-orthopyroxene ± hornblende ± clinopyroxene cumulates) host the Ni-Cu sulphide mineralization. Field mapping and petrographic study have …
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, …
The Nova-Bollinger Ni-Cu-platinum group element (PGE) deposit in the Fraser zone of the Albany-Fraser orogen consists of two main orebodies, Nova and Bollinger, hosted by the same tube-shaped intrusion but having distinctly different Ni tenors of around 6.5 and 4.8 wt %, respectively. Nova is also higher in Pd, but Cu and Pt tenors are similar.
We report whole-rock major, trace, and platinum-group element (PGE) geochemistry of volcanic rocks from the Teutonic Bore complex that hosts the Jaguar and Bentley Cu–Zn volcanogenic massive sulfide (VMS) deposits. This study aims to understand their sulfide saturation history and chalcophile element evolution during differentiation of the …

Mafic-ultramafic intrusive complexes possess a considerable capacity for hosting Ni-Cu-platinum group element (PGE) sulfide deposits. However, the mapping of small outcrops over large areas by field surveys is time-consuming. In this study, WorldView-3 (WV-3) data with moderate spectral and very high spatial resolution were employed for mapping mafic …
Platinum-group-element (PGE) geochemistry is the preferred method of identifying sulfide saturation in an evolving magma system for two reasons: first, their partition coefficients into immiscible sulfide melts are at least one to two orders of magnitude higher than Cu or Au, respectively, making them more sensitive indicators of sulfide ...

Low concentrations of Se, Cu and platinum-group elements (PGE) in harzburgites drilled at around 35–85 m below seafloor are consistent with the consumption of mantle sulfides after high degrees (>15–20 %) of partial melting and redistribution of chalcophile and siderophile elements into PGE-rich residual microphases. Higher concentrations ...
The world-class Jinchuan magmatic Ni-Cu-PGE (platinum-group element) sulfide deposit comprises four large orebodies (No. 1, 2, 3 and 24). Underground fan drilling discovered significant lateral extension of No. 2 orebody, referred as No. 2a in this study. From base to top, the No. 2a orebody comprises disseminated sulfide in olivine pyroxenites, net-textured ore in …
Platinum-group elements (PGE) are typically hosted in base metal sulfides and by platinum-group minerals (PGM) in Ni-Cu-PGE sulfide deposits. At Sudbury, it appears that the majority of PGE are hosted in PGM. In order to understand why this is the case we have investigated the origin of PGM from the 402 trough ore-bodies of the Creighton ...

Magmatic sulfide deposits containing nickel (Ni) and copper (Cu), with or without (±) platinum-group elements (PGE), account for approximately 60 percent of the world's nickel production. Most of the remainder of the Ni production is derived from lateritic deposits, which form by weathering of ultramafic rocks in humid tropical conditions.
