W inte r 20 1 9 23 be reviewed. The course will be set in a practical framework, with a focus on the understanding and usage of different algorithms without detailing the mathematics behind each algorithm. Through a series of case studies, examples and hands-on exercises the attendees will learn how to best apply machine learning to different datasets and most importantly, evaluate the results produced by the algorithms. Epithermal Ore Deposits and Transition to the Porphyry Environment: Formation and Exploration Saturday, January 18, and Sunday, January 19 Presented by Jeffrey W. Hedenquist, Consulting Geologist, Ottawa, Canada Most epithermal ore deposits form in the shallow (<1 km depth) magmatic- hydrothermal environment of volcanic arcs, with a commonly asymmetric transition to deeper (~1.5-3 km) intrusion-hosted ore deposits of the porphyry system. Alteration and subsequent precious and/ or base-metal mineralization at both epithermal and porphyry depths is related to the spatial and temporal evolution of the same hydrothermal system. Mineralogical interpretation is critical to assess epithermal and porphyry prospects: to determine erosion level (from paleosurface through the epithermal environment to near the tops of porphyry deposits); to correctly interpret geochemical and geophysical anomalies; and to estimate location, proximal or distal, relative to a potential ore deposit. Epithermal deposits also form in extensional settings with somewhat different mineralogy and metal characteristics, but with hydrothermal processes similar to those in arcs. Information from active hydrothermal systems, including fluids, flow paths and mineralogy, is useful when applied to exploring their extinct equivalents. This course stresses mineralogical interpretation coupled with exploration insights. Geochemical Data: Acquisition, Quality, Management, Interpretation Saturday, January, 18, and Sunday, January 19 Presented by: Dr. Dennis Arne and Dr. Pim van Geffen This two-day short course is designed for geology students and geologists at the start of their careers looking for an overview of best practices in exploration geochemistry. Day 1 of the course would also be suitable for database professionals wishing to know more about the collection of geochemical data and the assessment of its quality, as well as for more seasoned geologists wishing to review recent advances in the collection, analysis, QA/QC and interpretation of geochemical data. Controls on Precambrian Gold and Base Metal Deposits with a Focus on the Superior Craton Sunday, January 19 Presented by: Dr. Ross Sherlock, Dr. John Ayer, Dr. Bruno Lafrance and Dr. Harold Gibson Precambrian greenstone belts are an important metal source worldwide. As the rate of greenfield discoveries decreases, the challenge is to focus scarce exploration dollars to the most prospective areas to discover new deposits. The Mineral Exploration Research Centre (MERC) at Laurentian University conducts field and laboratory research on mineral deposits and their ore systems to develop new exploration methodologies. Student Guide to a Career in Exploration Sunday, January 19 Presented by: Andy Randell, SGDS Hive In this course, students will get the opportunity to learn more about the dynamic roles they will play in the exploration industry. The day will be split into two sessions, with the popular "Industry Speed Dating" in the morning, followed by "Exploration Monopoly" in the afternoon. Industry "Speed Dating" allows small groups of people to talk face-to-face with industry leaders and learn about all aspects of the exploration industry. Alongside the more obvious geological applications, this is an opportunity to learn about First Nations, environmental, new technology and laboratory testing, all of which play a vital role in the day-to-day life of an explorationist. The afternoon session of "Exploration Monopoly" follows on from the success of the 2017 session. This is a team-based game played in the style of Monopoly, where attendees can take a prospect through to a discovery – if the cards are right! PHOTOS: VELOUR PRODUCTIONS/AME
