From Drill Core to 3D Geological Modelling

November 16 2026, 9 a.m. to 4 p.m.
(Offered only in French)

Workshop Organizer: Florent Bigot (UQAM), Julia Dr. Kramer Bernhard (Anglo American), Antoine Caté (SRK Consulting), the SEG-UQAM, SEG-SGA ULaval-INRS, and SEG-UQAC student chapters

3D geological models are fundamental to mineral exploration, project development, and mine operations. They support a wide range of applications, including exploration targeting, geological interpretation, mineral resource estimation, and geotechnical, hydrogeological, and geometallurgical studies. These models are built primarily from drillhole data, with surface mapping, geochemical, and geophysical data providing additional constraints and context for the geological interpretation.

This one-day workshop will introduce participants to the main types of 3D geological models, the data required to build them, and the workflows and methodologies used to develop a robust digital 3D geological model. Particular emphasis will be placed on drill core data acquisition and on best practices for maximizing the value of information collected from drill core. Topics will include geological and lithological logging, structural data, geochemical assays, and core photography. The principal geological modeling approaches will be presented, along with guidance on their applicability to different project objectives and geological settings.

The presenters will cover both established, industry-standard workflows and innovative approaches that leverage emerging technologies. A series of practical modules will illustrate these methodologies through real-world examples and case studies. The workshop aims to provide participants with the knowledge and practical tools required to optimize data collection, validation, integration, and interpretation in support of robust 3D geological modeling and ultimately improve the value of geological information throughout the mining project lifecycle.
