LIBERTY STAR URANIUM & METALS CORP. (OTC:LBSR) announced on October 21, 2025, the successful completion of induced polarization (IP) and resistivity testing over known gold-bearing veins at its wholly owned Red Rock Canyon Gold Project, part of the Hay Mountain Project in southeast Arizona.
The geophysical test, conducted in July 2025, effectively detected and characterized gold-bearing veins. Key findings from the IP test indicate that gold-bearing veins are readily detectable, easily mapped, and characterizable using electrical geophysics. These veins exhibit higher resistivity than the hosting limestone due to their siliceous, jasperoidal nature, making them detectable even under soil cover. Additionally, the gold-bearing veins display higher IP values, confirming an association with sulfide mineralization, including pyrite and arsenopyrite, which is characteristic of Carlin-style deposits.
Dr. Jim B. Fink, CTO and geophysicist with Sub Rosa Monitoring LLC, who conducted the survey, stated that the test 'exceeded our expectations' and that the data 'did exactly what a calibration test should do light up what we already know is there'. He noted that the ability to detect, map, and characterize these veins represents a 'significant advancement' in exploration capabilities and provides a 'powerful tool for targeting future drilling programs'. Pete O'Heeron, Chairman of Liberty Star, commented that 'These breakthrough de-risking results validate our systematic approach to exploring the Red Rock Canyon Gold Project' and will allow the company to 'optimize our drilling programs and potentially identify additional high-grade targets'.
