Bio: Fabien Rabayrol is a PhD Candidate at the Mineral Deposit Research Unit at the University of British Columbia. He obtained his Master’s degree from the Institut Polytechnique LaSalle Beauvais in France in 2011. He subsequently worked for Balmoral Resources Ltd. and Teck Resources Ltd. as field geologist on grassroot exploration programs. Fabien is currently working on the tectonic-magmatic evolution of the Anatolide-Tauride metallogenic belt in Turkey as a part of the industry-sponsored MDRU - Western Tethyan Metallogeny project supervised by Dr. Craig Hart and Dr. Aleksandar Mišković. In March 2016, Fabien and his team (Data Miners) won 2nd place in the Integra Gold Rush Challenge by developing an innovative combination of 3D geological modelling and “machine learning” algorithm to extract useful information from Integra Gold’s database (6 To) and discover new potential mineralized zones at Sigma-Lamaque mine (Québec).

Abstract:

Improvements of exploration techniques are crucial for mining industry to keep on expanding their projects and make new mineral discoveries. The latest exploration techniques can also contribute to the re-opening of historical mine sites by re-interpreting old models in new technological and economic contexts, as for the Sigma and Lamaque mines in the Val d’Or district of the Archean Abitibi greenstone belt, province of Québec. As part of the Integra Gold Rush Challenge, the Data Miners proposed an innovative, geological and geostatistical workflow, both knowledge- and data-driven based on four steps: 1) data extraction and refinement, 2) three-dimensional (3D) geological modelling, 3) multi-component statistical analysis and 4) targets identification and validation. This approach combines the use of conventional exploration vectors stemming from up-to-date deposit-type metallogenic knowledge and a data-driven approach using statistical evaluation of exploration vectors and Machine Learning algorithms (artificial intelligence). The essence of Data Miners’ method is the combination of rigorous geological modeling with the Random Forest regression algorithm, which studies spatial relationships between numerous primary variables, and generates spatially continuous predictions for potential mineralization. The major strengths of this workflow include: drastic reduction of human-related errors, processing of extensive datasets, classification of key variables controlling gold distribution, swift identification of reliable exploration targets, and ease of exploration model improvements with new data input. During the competition, the Data Miners identified three distinct, high-potential, high-confidence exploration targets for the Lamaque and Sigma mines. These can be tested in the short term with a limited number of drill holes and, in the long term, become new major gold resources that will guarantee these mines a second fruitful life. Last but not least, the most significant impact of this work, in particular the use of artificial intelligence, is its applicability to property-wide data sets, and applicability to most geological environments, which will certainly contribute to future outstanding mineral discoveries in the well-endowed Abitibi Subprovince and beyond.
