Our guest is Dr. Ben Frieman, a Research Assistant Professor at the Colorado School of Mines in Golden. His talk is titled: Archean Geodynamic and Metallogenic Processes: Perspectives from the Southern Superior Province, Canada . Abstract: Constraining the factors that contribute to variable copper and gold metal endowment in the crust is critical for understanding the size and distribution of deposits of all ages, worldwide. This talk explores these factors through multi-disciplinary investigations conducted as part of the Metal Earth research initiative in Canada. This work was focused on the Archean Superior Province where similarly aged Archean domains display a disparate amount of known base and precious metals, typified by the well-endowed Abitibi subprovince and the lesser-endowed western Wabigoon subprovince. New integrated mapping, (isotope) geochemical, and geophysical results indicate that more prospective domains within these subprovinces contain dominantly juvenile crust with translithopheric structure which promoted a more direct crust-mantle connection coeval with their formation and tectonic modification. In contrast, less prospective areas contain a complex and protracted history of crustal growth and modification that spanned 100s of millions of years. These results indicate that exploration programs would benefit from incorporating more robust, broad-scale tectonic investigations in order to improve prospectivity constraints.

Our guest is Dr. Thomas Monecke, Professor of Economic Geology at the Colorado School of Mines in Golden. Watch as a leading authority in seafloor hydrothermal systems discusses exploration principles for VMS deposits. Summary: VMS deposits are the most well understood class of mineralizing systems due, in part, to their economic significance and the accessibility of active equivalents on the modern seafloor. Dr. Monecke reviews components of the VMS model, addressing the tectonic setting, volcanic stratigraphy and timing of emplacement, seafloor topography, PT considerations, structural controls, alteration vectoring, and other geological criteria the successful explorationist must take into account when exploring for VMS deposits.

Our guest is Britt Bluemel, Senior Geochemist with Goldspot Discoveries. Highly recommended for geoscientists interested in how AI is utilized in exploration and the publicly available tools you can utilize on your project. Summary: Britt Bluemel opens with a discussion of the fundamentals of artificial intelligence and machine learning and provides a case study from Tristar Gold's Esperanca South paleoplacer gold deposit in the Castelo De Sonhos Plateau of Brazil. Recorded April 5, 2021.

Our guest is Dr. Jon Thorson, DREGS' Distinguished Lecturer for 2019-20. His talk is titled: Basin Gold: Exploration Implications of Precious Metals in High-Chloride Brines Summary: Dr. Thorson discusses sedimentary basin processes, the formation of high-chlorine brines, and the potential for a class of sandstone and shale-hosted precious metals deposits in traditional base metal environments. Such deposits may or may not be associated with base metals, and consequently may not be properly evaluated for their precious metal content. Recorded on October 5, 2020

Our guest is Dr. Angel Abbud-Madrid, Director of the Center for Space Resources at the Colorado School of Mines in Golden, CO. His talk is titled: Resources Beyond Earth: Enabling Future Exploration and the New Space Economy. Summary: Dr. Abbud-Madrid discusses how growing resource needs will be addressed through extraterrestrial extraction, new technologies that will enable it, and how to efficiently utilize space resources. Recorded on September 15, 2020.
