Liberty Star Uranium & Metals Corp. (OTCQB:LBSR) announced today that it has successfully completed 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 survey, performed in July 2025, used close‑spaced 3‑meter (10‑foot) data intervals to detect and characterize gold‑bearing veins that exhibit higher resistivity than surrounding limestone due to their siliceous, jasperoidal composition and display elevated IP values associated with sulfide minerals such as pyrite and arsenopyrite. The precise mapping of vein geometry, strike, and dip provides a robust pre‑drilling grade estimation and supports the company’s goal of generating volumetric gold estimates through grid‑style surveys.
The results validate Liberty Star’s systematic exploration approach and represent a significant de‑risking milestone for the Red Rock Canyon project. By confirming the presence of gold‑bearing veins underground, the company can now optimize its drilling programs and target additional high‑grade targets that were previously undetectable due to soil cover. The close correlation between IP response and gold mineralization offers a powerful tool for future drilling programs, potentially accelerating the transition from exploration to development.
Company chairman Pete O’Heeron emphasized that the breakthrough de‑risking results align with the nation’s imperative to secure domestic sources of strategic minerals and streamline permitting under U.S. infrastructure and energy transition frameworks. Dr. Jim Fink, chief technology officer and geophysicist with Sub Rosa Monitoring LLC, noted that the data “did exactly what a calibration test should do—light up what we already know is there,” and that this may be the most positive IP survey results he has completed in his career. The successful application of IP technology at Red Rock Canyon positions Liberty Star to advance the project toward development and attract joint‑venture partnerships to fund future exploration and development activities.
