Ensuring a secure supply of metals to support a growing global population, increased urbanization and the transition to renewable energies is a priority for the future. Geochemistry is a fundamental tool that can be applied in developing genetic models of mineral deposits, regional to camp scale exploration, mineral processing and asset management and reclamation. At this conference we will bring together participants from academia, government and industry to discuss the latest concepts and newest ideas concerning the fundamental geochemical processes from the mantle to the crust that form mineral deposits at a range of scales. The evening sessions at the conference will address frontier issues that have an impact in mineral deposit formation; e.g. big data, the role of biology in mineral deposit formation and detection, marine mining and the next generation of geological models. A Gordon Research Seminar (GRS) on the Geochemistry of Mineral Deposits will be held for two days preceding the main GRC conference. The GRS is an opportunity for Early Career Researchers (PhD and Postdoctoral Researchers) to showcase their research activities and network.
