    Come and meet the University of Toronto's newest economic geologists.

    Russ Pysklywec, Professor and Chair of Earth Sciences will introduce the departments newest Assistant Professors, Dr. Daniel Gregory and Dr. Melissa Anderson, who will speak about their research in economic geology.

    Bios:

    Dr. Melissa Anderson (PhD, University of Ottawa and GEOMAR).  Dr. Anderson has just completed her postdoctoral research at the GEOMAR Helmholtz Centre for Ocean Research in Kiel, Germany.  She is an economic geologist doing research that looks at genetic and exploration models for massive sulphide deposits in back-arc tectonic terrains.

     Dr. Dan Gregory (PhD, CODES, University of Tasmania). Dr. Gregory is an economic geologist and geochemist who studies paleo-ocean chemistry and hydrothermal ore systems. In particular, he uses a host of micro-analytical techniques (NanoSIMS, LA-ICPMS, synchrotron-based XANES) on pyrite to characterize the geochemical profile of major mineral deposit types (porphyry, SEDEX, VHMS).

    Canada is covered by glacial sediments, and these shall be considered not as a hindrance to exploration, but as a tool. Mineralogy of glacial sediments has long been recognized as a powerful method, enabling not only to detect subtle dispersion trains, but also to characterize the mineralized source. Successes of gold grain counting and kimberlitic indicator minerals are countless.
    However, the method is surprisingly artisanal and did not evolved since 40 years, so easy discoveries were made and improvements are desperately needed. Various research groups currently work at defining a vast array of new indicator minerals for various type of mineralization. These methods were, until now, impaired by the incapacity to visually sort these minerals. The issue is currently circumvented by the use of automated mineralogy, a technology that was borrowed from geometallurgy as used in ore dressing. Mineral concentrates are scanned, grains by grains, by automated scanning electron microscope to detect the presence of chemically distinct indicator minerals.
    The technology is complex, but its efficiency is mind-blowing. And it evolves so quickly that even fashionable QEMSCAN are now heading to museum! A series of red-hot case studies, using rocket-science techniques, will be presented.


    Speaker Bios:

    Réjean Girard: P.Geo and president of IOS, he graduated from Laval University a long time ago as a mad scientist. Involved in more than 1400 exploration projects so far, his broad experience enabled him to bring out-of-the-box solution to the industry.
    Alexandre Néron: P.Eng, M.Sc, is the lead R&D scientist at IOS. He graduated from Université du Québec à Chicoutimi, but only after an incursion in electrical engineering at Sherbrooke University. Skilled in computer programming and machine learning, he is the one who takes the ideas and makes them working.

    Speaker:

    Adrian Martinez Vargas, Senior Resource Geologist, CSA Global

    Abstract:

    Are you a professional geologist hoping to gain new confidence in using the powerful Python programming language or a student looking to develop fundamental skills in resource estimation?

    The TGDG is delighted to host an interactive workshop covering the fundamentals of Python for resource estimation with Adrian Martinez Vargas.

    This training will provide you with an introduction to Python and other powerful Open Source software tools* for analysing geological data. Using these tools, we will dive into mineral resource estimation using Pygslib – a python module for mineral resource estimation and geostatistics.

    During this 1-day practical workshop you will undertake key resource estimation tasks:

    • import drill hole exploration data,
    • create and display drill hole objects,
    • model a geological unit,
    • select samples within the geological model,
    • statistically analyse and process drill hole assay values,
    • generate a block model and code it with geology,
    • estimate block model values,
    • validate the estimation results,
    • and report the mineral resource estimate.

    Bonus: Your resource estimation workflow will be recorded as an interactive Python script providing a complete record of the training exercise. For resource geologists this script has two valuable features: 1. It is auditable, allowing chosen parameters and assumption to be reviewed in future; and 2. It can be used to reproduce the estimate or update the estimate with new data.  

    In addition to learning the fundamentals of Python for mineral resource estimation, you will acquire useful Python skills that can be applied to a variety of other tasks. For example: working with common data and 3D model formats used in exploration and mining, accessing files that are too big for Excel to handle and visualizing geological data in 3D using Open Source software*.

    We hope this training will spark an interest in Python, a tool that has an enormous number of applications in Geology ranging from mining to machine learning.

    * Open source software will include: Jupyter Notebook, NumPy, Pandas, and ParaView.

    Speaker Bio:

    Adrian is both a geologist and a geostatistician. He produces open source software for geostatistics and mineral resources in Python, Fortran, Cython, C and SQL. He has worked as a consultant since 2002 covering many commodities including gold, copper, nickel, chromium, and industrial minerals.

    Adrian has considerable experience using multiple indicator kriging for resource estimation of gold deposits with high nugget and domaining issues; with non-linear geostatistics and with conditional simulations for resource estimation and model validation.

    Adrian has previously worked as an Assistant Professor in Cuba and Ethiopia, teaching geology and geostatistics.

    Intended Audience:

    This course is designed for students and young mining professionals looking to learn the basics of geological data manipulation with the user friendly computational language, Python.  No previous experience in resource modelling or using Python is necessary.  Participants should have an understanding of drill hole database construction and basic methods for statistical analysis of exploration data. 

    This is an incredible opportunity that the TGDG is pleased to offer at a very economical rate as part of their commitment to support valuable and resume building educational events for students and young mining professionals.

    Fees:

    Student: $50

    Member: $100

    Non-member: $150 (Registration for non-TGDG members - includes annual TGDG membership for remainder of 2018-2019 season.)

    Course fees include lunch and refreshments.

    Prerequisites:

    Registrants will need to bring their own laptops.  Software will be provided. Registrants will be notified by email with download and installation instructions.
