Improve depth of resolution with resistivity survey by applying MT technology
Traditional resistivity surveys can map conductors low the unconformity and provide information on potential alteration halos around uranium deposits. However, the overall depth of penetration is limited to depths of roughly 500 – 700 meters even for large array based surveys. In deeper terrains array based MT resistivity can provide compelling images that can help investigate depths of 300 m to 2000 m.
In deeper terrains array based MT resistivity can provide high lateral resolution while also providing significantly improved depth of investigation from surface to 2000 m.
The integration of distributed MT offers a high-impact, cost-effective solution for modern exploration:
· Operational Efficiency: MT data can be acquired simultaneously with DCIP surveys for a modest 25% cost premium, or as a standalone alternative at a significantly lower cost per kilometer.
· Enhanced Resolution: MT often delivers sharper imaging of sub-vertical basement structures and subtle stratigraphic layers that DC methods may overlook.
· Reduced Ambiguity: An integrated DC and MT approach provides multiple resistivity models that complement one another during interpretation.
