The 5-year research program is divided into 4 themes that address important issues to ensure long-term andresilient gold mining in providing next generation knowledge to understand the formation of orogenic golddeposits and to develop innovative exploration methodologies using indicator minerals and field portableinstruments. Theme 1 will investigate the petrologic and metamorphic setting of important gold deposit areas to enable better regional targeting. Theme 2 will study the origin of the hydrothermal fluids that formed thegold deposits, of the ligands that carry gold and associated metals in solution, and determine the detailedtiming of the gold-bearing hydrothermal events by in situ geochronology. Theme 3 will develop innovativeindicator mineral methodologies to improve the exploration toolbox of the partners with geochemical criteria to fingerprint, vector towards oreshoots, and assess fertility for gold mineralization for efficient targeting at the deposit scale. Theme 4 will develop exploration methodologies using field portable instruments (LIBS, SWIR) for rapid results that will maintain and increase the edge of the Canadian mineral exploration sector withefficient, flexible toolboxes.

这项为期 5 年的研究计划分为 4 个主题，解决重要问题，以确保长期和有弹性的金矿开采，提供下一代知识以了解造山金矿床的形成，并使用指示矿物和现场便携式仪器开发创新的勘探方法。主题 1 将调查重要金矿区的岩石学和变质环境，以便更好地确定区域目标。主题 2 将研究形成金矿床的热液流体的起源、溶液中携带金和伴生金属的配体的起源，并通过原位地质年代学确定含金热液事件的详细时间。主题 3 将开发创新的指示矿物方法，以改进合作伙伴的勘探工具箱，采用地球化学标准进行指纹识别、导向矿芽，并评估金矿化的肥力，从而有效瞄准矿床规模。主题 4 将开发使用现场便携式仪器（LIBS、SWIR）的勘探方法，以快速获得结果，从而通过高效、灵活的工具箱保持和增强加拿大矿产勘探行业的优势。
