Liberty Star expands Arizona mineral footprint with new claims

Liberty Star Uranium & Metals Corp. reported that Liberty Star Minerals has staked 13 additional mining claims in southeast Arizona.

Rhea-AI Filing Summary

Liberty Star Uranium & Metals Corp. reported that Liberty Star Minerals has staked 13 additional mining claims in southeast Arizona. These new claims cover about 11.18 square miles and increase the company’s total mineralized footprint to roughly 31.49 square miles, ranking Hay Mountain Holdings, LLC as the 4th largest mineral footprint in Arizona.

The new claims lie within the Tombstone Mining District and expand the contiguous land position around the Hay Mountain Holdings umbrella, which includes Earp Ridge Mines, Red Rock Mines and American Strategic Minerals. The expansion is aimed at capturing extensions of known structural and geophysical trends identified through recent mapping, sampling and induced polarization survey work.

The company stated that the enlarged land position is intended to preserve future optionality for potential open-pit and underground development and to secure additional gold and polymetallic targets. Liberty Star continues exploration at Red Rock Canyon and the broader Hay Mountain area, including follow-up drilling design, more geochemical sampling and refined 3D geophysical interpretation.

Insights

Mining sector analyst

Liberty Star expands Arizona land package to support future exploration.

Liberty Star added 13 mining claims covering about 11.18 square miles, bringing its total mineralized footprint in southeast Arizona to roughly 31.49 square miles. Management highlights this as placing Hay Mountain Holdings, LLC among the largest mineral land positions in the state.

The new claims extend across the Tombstone Mining District and are positioned to capture structural and geophysical trends identified by mapping, sampling and induced polarization work. Targets span gold, copper, molybdenum, rare earth elements and broader polymetallic mineralization within Arizona’s prolific porphyry copper belt.

The company frames the expansion as preserving optionality for both open-pit and underground development scenarios and for securing additional targets along regional structures. Actual value creation will depend on future drilling, assay results and technical studies, which the company plans to advance and report as fieldwork progresses.

The newly added claims 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 and American Strategic Minerals LLC, the area reserved for REEs. The expanded claim 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.
