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

Darrell Epp, 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…

Aurora Rapid Reactance Tomography (ARRT) is a new method and instrument in ground geophysical exploration produced by Aurora Geosciences Ltd. (AGL), closely related to Geometrics’s OhmMapper (Geometrics, 2009).

Geophysical methods for kimberlite exploration in northern Canada

Dave White, May 3, 2023 | Geophysics

In 1991, the discovery of diamondiferous kimberlite in Canada's Northwest Territories (NWT) precipitated the largest mineral staking rush in North America and sparked a remarkable exploration effort which extended across northern Canada. Thirteen year…
