Liberty Star Minerals (OTCQB: LBSR) has initiated a 3D induced polarization (3D IP) survey at its Red Rock Canyon Gold Project in southeast Arizona. The company has partnered with Dr. Jim Fink from Sub Rosa Monitoring LLC to conduct the survey across 10 acres of gold-bearing outcrops.

The survey aims to map gold-bearing pyrite distribution using pole-to-pole array configuration, capable of surveying depths up to 500 feet. The data will be calibrated with historic drill hole locations to identify and prioritize exploration targets for future drilling programs.

Liberty Star Minerals (OTCQB: LBSR) ha avviato un'indagine di polarizzazione indotta 3D (3D IP) presso il suo progetto Red Rock Canyon Gold nel sud-est dell'Arizona. L'azienda ha collaborato con Dr. Jim Fink di Sub Rosa Monitoring LLC per eseguire il rilievo su 10 acri di affioramenti auriferi.

L'indagine mira a mappare la distribuzione della pirite aurifera utilizzando una configurazione a array polo-polo, in grado di esplorare fino a una profondità di 500 piedi. I dati saranno calibrati con le posizioni storiche dei fori di perforazione per individuare e prioritizzare gli obiettivi di esplorazione per i futuri programmi di perforazione.

Das Unternehmen arbeitet mit Dr. Jim Fink von Sub Rosa Monitoring LLC zusammen, um die Vermessung über 10 Acres goldhaltiger Aufschlüsse durchzuführen.

Ziel der Vermessung ist es, die Verteilung von goldhaltigem Pyrit mit einer Pol-zu-Pol-Array-Konfiguration zu kartieren, die Tiefen von bis zu 500 Fuß erfassen kann. Die Daten werden mit historischen Bohrlochstandorten kalibriert, um Explorationsziele für zukünftige Bohrprogramme zu identifizieren und zu priorisieren.

TUCSON, AZ, June 30, 2025 (GLOBE NEWSWIRE) -- Liberty Star Minerals (“Liberty Star” or the “Company”) (OTCQB: LBSR) is pleased to announce the launch of a state-of-the-art 3D induced polarization survey (“3D IP Survey,” “Survey”) at its wholly owned Red Rock Canyon Gold Project (RRC), part of the Hay Mountain Project in southeast Arizona. ​ The Survey aims to be the next initiative to unlock the immense potential of RRC, which is believed to host commercially significant metals associated with epithermal gold mineralization, a hallmark of the mineral-rich region, known as the gold copper belt spanning central Arizona to northern Mexico. ​

Liberty Star has engaged Jim Fink, PhD, PE, RLS, Geological Engineer, Geophysicist, and Chief Technical Officer at Sub Rosa Monitoring LLC, a leading Tucson-based geophysical survey company. Together they will conduct a 3D Induced Polarization (IP) survey across approximately 10 acres of the Company’s most promising gold-bearing outcrops, aligned with historic drill hole locations. By calibrating the survey to known gold intercepts from legacy data, the geology team aims to trace the distribution of pyrite-both at the surface and shallow depths-using a pole-to-pole array configuration. This technique will provide an effective means of mapping gold-bearing pyrite across significant portions of the RRC project area. The resulting data will help Liberty Star identify and prioritize high-value exploration targets near previously drilled zones where gold has already been encountered. These interpretations will guide the prioritization of future drill targets in proximity to known mineralized intercepts.

“The 3D IP survey calibration will show us where to drill by lighting up the gold at depth extensively” comments Jay Crawford, Liberty Star’s Vice President of Field Operations.

“This cutting-edge technology allows us to survey depths up to 500 feet, representing a significant leap forward from traditional methods. ​ Combined with our recent fieldwork analyzing near-surface geochemical data, the 3D IP Survey will refine our drill targets and focus exploration on the most promising areas of the RRC property. ​ We are excited to follow up this survey with additional drilling, including a targeted drill program.” ​
