In collaboration with Veracio (formerly Boart Longyear) and their extensive expertise, we developed the TruStructure application — a cutting-edge, web-based platform for structural and geotechnical logging. This innovative solution harnesses the power of deep learning segmentation models to analyse drill core imagery acquired through the TruScan system, delivering precise, reliable and unbiased insights into the structure and integrity of core samples.

By employing semantic segmentation, a pixel-level classification technique, the TruStructure application identifies and delineates key features within the images associated with structural logging. These features include the core itself, orientation lines (olines), borders, veins, fractures, and the background. Leveraging a dataset meticulously labelled by geological experts, a custom deep learning model has been trained to autonomously infer and segment these classes.

What sets the TruStructure application apart is its custom model's ability to maintain high-resolution representations throughout the network architecture. Through a strategic fusion of high-resolution feature maps from lower-level layers and lower-resolution feature maps from higher-level layers, the model effectively preserves fine-grained details and captures comprehensive contextual information, ultimately yielding highly accurate segmentation results.

Empowered by this advanced machine learning solution, the TruStructure application empowers geologists and mining professionals with unparalleled precision in analysing the structural and geotechnical characteristics of drill core samples, all whilst eliminating the manual handling of core. By enhancing the understanding of core structures and rock integrity, the application significantly contributes to efficient decision-making in drilling programs, the delineation of mineralisation zones and resource development. With TruStructure, stakeholders can make informed choices, optimise operations, and drive successful mining endeavours.
