"By integrating sparse drilling with high-volume geophysics, GiLi transformed structural uncertainty into a defensible 3D model, giving us the clarity and confidence to know exactly where to drill next"

Integrated 3D Lithology Modelling with GiLi at the Carpenter Lake Uranium Project

Greenridge Exploration’s Carpenter Lake Uranium Project is strategically located along the Cable Bay Shear Zone (CBSZ) in the southern margin of the Athabasca Basin. Despite extensive airborne geophysics and geological data (surface mapping, drillhole logs), fully resolving the steep, shear-hosted conductors remained a challenge for traditional inversion methods.

CGI, in collaboration with Convolutions Geoscience Corp., deployed its proprietary GiLi (Geophysics-Informed Lithology Interpolation) platform to bridge the gap between these disparate datasets. By leveraging machine learning to integrate the geological data with the airborne magnetics, GiLi produced a unified 3D voxel model that automatically aligns geological inputs with physical property measurements.

This advanced workflow successfully defined steeply dipping conductive panels and density-low signatures across more than 15 km of the CBSZ corridor. The resulting GiLi model provided Greenridge Exploration with a refined structural framework to further advance their exploration project. This project proves that CGI’s next-generation modelling can extract significant discovery value from existing data without the need for costly new field acquisition.

The GILI 3D lithology model, shown in a section cut perpendicular to the Cable Bay Shear Zone, highlights the distribution of modeled lithologies, the principal interpreted fault, and the graphitic pelite horizon rendered as a solid surface (orange).

The missing link between the geophysics and the drillholes:

The GILI platform creates a 3D model of interpolated lithology that adheres to geological inputs while precisely fitting geophysical data, combining the broad spatial coverage of geophysical surveys with the granularity of in-situ measurements. This method generated a high-resulution model of the conductive graphitic pelite target (c), and materially improved Greenridge's understanding of structural architeture along the Cable Bay Shear Zone.
