The MAX molybdenum deposit is located in the Selkirk Mountains of southeastern British Columbia in a broad northwest-trending belt of Early Cambrian metasedimentary rocks bordering the northern end of the Kootenay Arc. Molybdenite mineralization is associated with a Late Cretaceous aged granodiorite intrusion, and concentrated within several steeply plunging granodiorite apophyses that root into a larger underlying pluton. Previous work in the 1980s at the MAX molybdenum project focused on evaluating the structural evolution of the deposit, characterizing the hydrothermal alteration patterns, and quantifying the evolving chemistry of the mineralizing fluids (Linnen and Williams-Jones, 1987; Linnen and Williams-Jones, 1990; Boyle and Leitch, 1983).
The current study will develop a chronological and evolutionary framework for the formation of the MAX deposit incorporating trace element geochemistry of the host intrusion, field observations, fluid inclusion analysis, and previous studies to establish a comprehensive metallogenic model. Underground mapping and analysis of diamond drill holes will place samples within a geologic context. High precision TIMS U-Pb dating of selected samples will be used to determine when the host intrusions were formed, and Re-Os dating of molybdenite from various paragenetic stages of the deposit will constrain the time span of ore formation. Conclusions generated from the current project will directly contribute to ongoing exploration efforts in and around the MAX property for similar style molybdenum deposits.
