TUCSON, AZ, March 10, 2026 (GLOBE NEWSWIRE) -- Liberty Star Minerals (OTCQB: LBSR) (“Liberty Star” or the “Company”), a U.S. mineral exploration company focused on strategic and commercially important critical minerals in southeast Arizona, today announced that it has staked an additional 13 mineral exploration permits (MEPs) covering approximately 11.18 square miles, increasing its total mineralized footprint to approximately 31.49 square miles and ranks Hay Mountain Holdings, LLC as the 4th largest mineral footprint in Arizona.
The newly added MEPs lie within the broader Tombstone Mining District and expand Liberty Star’s contiguous land position surrounding its Liberty Star Hay Mountain Holdings LLC, which includes Earp Ridge Mines, LLC, the multi-mineral claims which include critical minerals, copper, and molybdenum, historically known as Hay Mountain Target 1 & 2. It also encompasses Red Rock Mines, LLC The Company’s world-class gold target. The expanded MEPs block is designed to capture extensions of known structural and geophysical trends identified through recent geologic mapping, sampling, and induced polarization (IP) survey work.
“Over the last year, our technical team has continued to deliver compelling evidence that we are in a large, mineralized system with bonanza-grade gold values and robust geophysical signatures at Red Rock Canyon and across the entire Hay Mountain Holdings umbrella,” said Pete O’Heeron, Chairman of Liberty Star Minerals. “The mineral-rich assays we are seeing compel us to protect a larger perimeter, which places our project in the Top 5 in the state of Arizona, as we advance our gold deposit and develop critical minerals that are important to U.S. economic and national security.”
The Company noted that the enlarged land position is intended to preserve future optionality for potential open-pit and underground development scenarios and to secure additional targets along regional structures that may host gold and polymetallic mineralization.
Liberty Star’s projects are located within Arizona's prolific porphyry copper belt in southeast Arizona, one of the world's most renowned regions for large-scale copper-gold-molybdenum deposits, a state recognized as a leading U.S. jurisdiction for copper and other critical mineral production.
Liberty Star continues to advance its exploration programs at Red Rock Canyon and the broader Hay Mountain area, including follow-up drilling design, expanded geochemical sampling, and refined 3D interpretation of geophysical data. The Company will provide additional updates as fieldwork progresses and new assay or geophysical results become available.
