These characteristics suggest that sulfides in the massive ores are of magmatic origin, co-genetic with their host rocks.The relatively high Pt/Pd ratios of the Baimazhai massive sulfide ores (averaging 0.83) and their host rocks imply that the Baimazhai sulfides formed in a single sulfide saturation event, but not through multiple sulfide injections.Four kimberlite pipes occur in close proximity—three are being exploited, while the fourth will be brought into production in 2018.Diavik is now expected to operate through 2024; upon closure, the equipment, buildings, and infrastructure will be removed and the land returned as closely as possible to its original condition.Isochrons are created by analysing several samples believed to have formed at the same time from a common source.

In addition, the Pt/Pd and Cu/Pd ratios of the massive sulfide ores are similar to those of olivine pyroxenite, gabbro and websterite.High Ir contents (0.77–5.52 ppb, averaging 2.35 ppb) and dramatically variable Pd/Ir ratios (4.76–296, averaging 138) of the massive sulfide ores suggest that the Baimazhai sulfide ores might have suffered significant late stage hydrothermal alteration. The Diavik diamond mine, shown here in February 2015, is located on a small island in Lac de Gras, approximately 300 km northeast of Yellowknife and 220 km south of the Arctic Circle, in a remote region of Canada’s Northwest Territories. The Diavik mine, located in the Archean-age Slave geologic province in northern Canada, is one of the world’s preeminent sources of gem diamonds.The intruded lamprophyre dykes also show low ΣPGE (2.98–4.07 ppb).The ΣPGE exhibit obvious positive correlations with Au, Ni and Cu contents.Rhenium and osmium isotopes in sulfide minerals from the deposit have been used to determine the timing of mineralization and the source of osmium and, by inference, the ore metals.Sulfide ore samples have osmium and rhenium concentrations of 0.28-1.07ppb and 2.39-13.17ppb, respectively.Cu and Mo have different distributions in the Porphyry Ore Zone with Cu concentrating above the porphyry and with Mo inside of porphyry intrusion.The direct Re-Os dating on Cu sulfides will be helpful for us to understand the Cu and Mo mineralization at Jiama.Citation: Han CM, Xiao WJ, Zhao GC, Su BX, Ao SJ, et al.(2014) Re–Os Isotopic Age of the Hongqiling Cu-Ni Sulfide Deposit in Jilin Province, NE China and its Geological Significance. doi:10.4172/2169-0049.1000118Copyright: © 2014 Han CM, et al.
