Liberty Star Uranium & Metals (LBSR) reported the successful completion of an induced polarization (IP) and resistivity test over known gold-bearing veins at its wholly owned Red Rock Canyon Gold Project within the Hay Mountain Project in southeast Arizona.
The July 2025 geophysical work detected and characterized the veins as intended. Results showed the veins: (1) are readily detected and mapped with electrical geophysics; (2) have higher resistivity than the hosting limestone due to their siliceous, jasperoidal character, aiding detection even under soil cover; and (3) exhibit higher IP values tied to sulfide mineralization (pyrite and arsenopyrite) consistent with Carlin-style deposits. The company said the findings will guide future drilling targets.
