GeologyCore

GeologyCore (also referred to as Vulcan GeologyCore) is Maptek's dedicated geological modelling environment, released in 2021. It provides a workflow-based interface guiding geologists through six key steps: loading and validating data, defining geological domains, and generating, validating, and publishing models. It supports multiple modelling techniques — machine learning, traditional vein modelling, stratigraphic modelling, and implicit modelling — within a single, streamlined interface.

GeologyCore integrates seamlessly with Vulcan: users manage drillhole and mine data in Vulcan, proceed to GeologyCore for domain modelling and validation, and then publish results back to Vulcan for grade estimation. A key design philosophy is reducing the technology barrier for geologists by automating data validation — cited as the biggest time sink in traditional modelling workflows — so geologists can focus on higher-value interpretation. GeologyCore is available standalone for new customers or as part of Vulcan GeoModeller and GeoStatModeller bundles.

GeologyCore also serves as the required foundation for the DomainMCF machine learning add-on. Recent developments (2023–2025) added enhanced fault handling, internal DomainMCF access, and integration with Maptek's Vestrex cloud platform.
