Gamma Acquisition Highlights Risks and Opportunities in Critical Minerals Race

• PNN invited by Australian Embassy to brief Ambassador Kevin Rudd on Gamma Project
• Gamma Project acquisition pending, located near Mountain Pass Mine in California
• Project seen as key to strengthening Australia-US heavy rare earth supply chains
• PNN plans accelerated exploration and pursuit of US government support
• Gamma holds significant heavy rare earth and uranium potential with limited recent drilling

Strategic Briefing Ahead of High-Level Talks

Power Minerals Limited (ASX, PNN) has been formally requested by the Australian Embassy in Washington DC to provide a detailed briefing on its upcoming acquisition of the Gamma Heavy Rare Earths Project in California. This briefing is scheduled ahead of the high-profile meeting between Australian Prime Minister Anthony Albanese and US President Donald Trump on 20 October 2025. The involvement of His Excellency The Hon Dr Kevin Rudd AC, Australian Ambassador to the United States, highlights the strategic significance of the Gamma Project within the broader Australia-US partnership on critical minerals.

Positioning Gamma in the Critical Minerals Landscape

The Gamma Project is situated in San Bernardino County, a mining-friendly region that also hosts the Mountain Pass Mine, the only rare earth element (REE) producing mine in the United States. Owned by MP Materials Inc, Mountain Pass focuses on light rare earth elements (LREE), whereas Gamma is rich in heavy rare earth elements (HREE), which are crucial for advanced technologies and defence applications. This geographic and resource complementarity positions Gamma as a potentially vital supplier to the US heavy rare earth supply chain, addressing a critical gap in domestic production.

Accelerated Exploration and Government Engagement

Following the anticipated completion of the acquisition, PNN intends to rapidly advance exploration activities at Gamma. The company is also actively pursuing US government initiatives aimed at expediting permitting processes and securing federal funding. These efforts align with recent US policy moves to strengthen domestic critical mineral supply chains amid geopolitical tensions and reliance on foreign sources, particularly China’s dominance in rare earth processing.

Broader Geopolitical and Economic Implications

The Australian Government’s interest in the Gamma Project, as evidenced by the embassy’s request for a briefing, underscores Canberra’s leadership in fostering strategic cooperation with Washington on critical minerals. Australia is reportedly considering a A$1.2 billion strategic minerals reserve focused on rare earths, potentially in partnership with the US, further cementing the bilateral alliance’s commitment to securing supply chains essential for energy transition and national security.

Untapped Potential and Future Prospects

Gamma’s exploration history is sparse, with no drilling conducted in nearly five decades and only recent sampling revealing high concentrations of heavy rare earth elements and uranium. The project’s proximity to Mountain Pass and its unique geological characteristics suggest significant upside potential. Should exploration confirm these prospects, Gamma could become a cornerstone asset in the evolving critical minerals landscape, benefiting both PNN and the strategic interests of Australia and the United States.

Bottom Line?

PNN’s Gamma Project briefing signals a pivotal step in Australia-US rare earth collaboration, with exploration and policy developments to watch closely.

Questions in the middle?

• Will PNN secure US government funding and expedited permits to fast-track Gamma development?
• How will exploration results at Gamma influence its strategic value and potential partnerships?
• What role will Australia’s proposed strategic minerals reserve play in supporting projects like Gamma?
