Optimizing VLF Survey Design and Interpretation

Eileen Lyon, B.Sc., P.Geo, July 29, 2026 | Geophysics

Most know what VLF does well: rapidly identifying conductive structures. What is less widely recognized is how modern processing can turn profiles into models that support geology.

Aurora Rapid Reactance Tomography (ARRT) - Rapid Electrical Imaging for Mineral Exploration

Darrell Epp, B.Sc. (Hons), June 22, 2026 | Geophysics

ARRT is is a non-invasive, logistically efficient resistivity method capable of turning field measurements into meaningful subsurface interpretations. Variations in resistivity often reflect changes in lithology, alteration, structure, or mineralizati…
