NRED Intelligent Mining Inc. has released the results of an integrated review combining shallow airborne resistivity data and 926 classified soil samples from the Wilmac Copper-Gold Project in British Columbia’s Quesnel porphyry belt, establishing an empirical 211 ohm-metre screening division to distinguish conductive cover from resistive basement ground.

The review strengthens the working model indicating that younger Princeton Group rocks may obscure older Nicola Group and intrusive rocks considered more favourable for exploration. Property-scale 40 kilohertz airborne apparent-resistivity data from a 2008 Fugro RESOLVE helicopter survey identify a broad, conductive eastern domain influenced by Princeton Group cover, while soil classifications provide local-scale information to refine the transition toward more resistive basement ground.

For the review, researchers selected 211 ohm-metres as an empirical screening division, representing the 30th percentile of the property-scale 40 kilohertz dataset. Values at or below this threshold are relatively conductive and potentially cover-influenced, while values above it are relatively resistive and potentially more basement-influenced.

The evaluation tested 926 soil samples across eight geochemical groups. SED and QUAT soil groups returned median apparent resistivities of 288 and 311 ohm-metres respectively, with approximately 33% and 27% of sites falling below the 211 ohm-metre threshold. In contrast, the REG group yielded a higher median apparent resistivity of 383 ohm-metres, with only 11% of sites below the screening division.

A detailed 2.5 by 1.8-kilometre North Lamont comparison containing 96 classified soil samples demonstrated the broader relationship between cover-influenced soils, the conductive eastern domain, and the transition toward more resistive ground.

“This analysis provides us with a clearer picture of where prospective basement rock may be exposed and where it may be hidden beneath younger cover,” said Brian Goss, Chief Executive Officer of NRED Intelligent Mining Inc. “Together, they give us a stronger framework for mapping, follow-up, and future drill targeting.”

NRED holds the 16,078-hectare Wilmac project under option within the Quesnel porphyry belt. Historical exploration work at the project includes data compiled across approximately 19 assessment reports filed between 1968 and 2025 alongside 10 mineral occurrences.

To test the refined cover model, NRED plans to use pre-selected field transects incorporating geological mapping, shallow pits or auger holes, documented soil horizons, and ground conductivity or resistivity measurements. The company is also advancing the acquisition of a drill permit for the Wilmac Project to support an initial drill program planned for the fall of 2026.
