Sanborn, through its subsidiary EDCON-PRJ, Inc., is expanding its geothermal surveying operations to support growing demand for advanced subsurface data across the western United States. With three recent aeromagnetic surveys completed in the past two months and additional projects underway, EDCON-PRJ is helping developers, research outfits, and public agencies better evaluate domestic geothermal resources.
High-resolution magnetic surveys play a critical role in geothermal exploration by helping identify basement architecture, fault and fracture networks, caldera and intrusive complexes, lithologic contacts, and zones of hydrothermal alteration. By mapping magnetic susceptibility contrasts tied to structure and alteration, EDCON-PRJ’s datasets help project teams refine conceptual models, reduce exploration uncertainty, and make more informed drilling decisions.
“As geothermal development accelerates, the industry needs geophysical data that directly informs subsurface structure and reservoir controls,” said Nathan Campbell, General Manager and Geophysicist for EDCON-PRJ. “Our recent surveys are focused on delivering magnetic datasets that can be directly integrated with geologic, geochemical, and well data to improve resource assessment and move projects forward with confidence.”
EDCON-PRJ’s experience in geothermal exploration includes participation in major public sector initiatives such as the U.S. Geological Survey Earth Mapping Resources Initiative EarthMRI. As part of the GeoFlight Salton Trough project, EDCON-PRJ conducted a high resolution magnetic and radiometric survey over the Imperial Valley and Salton Sea region of southern California from January 2022 through Spring 2023. Supported by the USGS and the Department of Energy Geothermal Technologies Office, the survey focused on advancing understanding of hidden geothermal systems and lithium bearing brines in one of the most productive geothermal provinces in the United States.
Sanborn’s acquisition of EDCON-PRJ has expanded access to specialized aircraft, sensors, and complementary geophysical capabilities, supporting the company’s broader range of airborne and ground-based survey programs. Sanborn also manufactures radiometric systems used in many airborne programs, including the Sanborn AGRS radiometric system under the Sanborn Geophysics Group, which also includes Sanborn Geophysics ULC.
Sanborn remains committed to delivering advanced geophysical solutions that support energy security, resource sustainability, and the transition to a cleaner and more sustainable energy future.
