Power Minerals Secures High-Grade Rare Earth Project Near $20B Mountain Pass Mine
Power Minerals Limited (ASX: PNN) has executed an option agreement to acquire the Gamma Heavy Rare Earths Project in California's mining-friendly San Bernardino County, strategically positioned near MP Materials' $20 billion Mountain Pass Mine. The company has simultaneously secured $4.1 million in placement funding, with participation from Tribeca Investment Partners and S3 Consortium (Next Investors).
Strategic Acquisition in America's Critical Minerals Hub
The Gamma Project represents an exciting opportunity in America's critical minerals landscape. Located in the same highly prospective rare earth elements (REE) precinct as the only REE-producing operation in the United States, this acquisition positions Power Minerals to potentially become a significant player in the domestic REE supply chain.
The project's exploration history mirrors that of the world-class Mountain Pass deposit – initially investigated for gold and uranium before the discovery of rare earth mineralisation. This parallel development path suggests the Gamma Project may hold similar potential for significant REE deposits.
Historical rock chip sampling at Gamma has revealed exceptional grades of both rare earth elements and uranium:
Key REE results include:
- 20,257ppm (2.03%) TREO, including 10,732ppm (1.07%) HREO in sample 107709
- 16,978ppm (1.70%) TREO, including 8,830ppm (0.88%) HREO in sample REE-1
- 12,384ppm (1.24%) TREO, including 5,897ppm (0.59%) HREO in sample 107710
Highlight uranium results include:
- 15,150ppm U (1.786% U₃O₈) in sample JM-03
- 10,300ppm U (1.214% U₃O₈) in sample JM-04
- Historic drilling with 6.25m at 1.30% U₃O₈ from 24.08m depth
Understanding Heavy Rare Earth Elements (HREE)
Heavy Rare Earth Elements represent a particularly valuable subset of the rare earth group. While light rare earths like cerium and lanthanum are relatively abundant, HREEs are significantly rarer and command higher prices in global markets.
HREEs are defined chemically as those elements with equal (Gadolinium) or over half-filled 4f electron orbits. This includes elements such as Gadolinium (Gd), Terbium (Tb), Dysprosium (Dy), Holmium (Ho), Erbium (Er), Thulium (Tm), Ytterbium (Yb), Lutetium (Lu), and Yttrium (Y).
What makes the Gamma Project especially notable is its high proportion of heavy rare earth oxides. Ten out of twelve of the initial grab rock samples contain more than 50% of the total rare earth oxide content comprised of heavy rare earth oxides. This contrasts sharply with MP Materials' Mountain Pass Mine, which primarily produces light rare earths.
HREEs are crucial components in various high-tech applications:
- Defence Technologies: Precision-guided missiles, radar systems, and jet engines
- Advanced Electronics: Hard drives, speakers, and microphones
- Medical Equipment: MRI contrast agents and surgical lasers
- Clean Energy: Wind turbines and electric vehicle motors
The high HREE content at Gamma could position Power Minerals to supply critical materials for these advanced technologies, particularly in sectors where the U.S. is actively seeking domestic supply chains.
Exploration Potential and Strategic Value
What makes the Gamma Project particularly intriguing is that historical drill cores were never assayed for rare earth elements. This presents a significant opportunity for Power Minerals to rapidly advance exploration by analysing existing materials alongside new targets.
The property features a distinct uranium zone separate from the rare earth zones – another characteristic it shares with the Mountain Pass REE Mine. This dual mineral potential enhances the project's economic prospects.
"We are very excited about the potential of the Gamma Project to add to and complement our suite of critical minerals projects. Gamma represents a high-grade, early-stage exploration asset, which we see has the potential to be rapidly advanced with the application of targeted, modern exploration activities." – Managing Director, Mena Habib
Habib also highlighted a potential strategic opportunity: "The Mountain Pass operation produces Light REE only (and lacks Heavy REE); Power sees a future potential opportunity to provide HREE feedstock from the Gamma Project to the Mountain Pass mine, subject to the successful exploration and development of Gamma."
$4.1 Million Placement to Fund Aggressive Exploration
The company has secured firm commitments for a $4.1 million placement from sophisticated and professional investors, including Tribeca Investment Partners and S3 Consortium (Next Investors). The placement will be conducted in two tranches:
- Tranche 1: $3.4 million to be settled around October 15, 2025
- Tranche 2: $700,000 anticipated to settle within approximately 60 days, pending shareholder approval
Placement participants will receive one PNNOA option for every two shares issued, with an exercise price of $0.10 per share and expiring on December 29, 2029.
The funds will be directed toward immediate exploration activities at Gamma, including surface rock sampling and mapping, soil sampling, aerial drone magnetics, and additional claim staking. Power Minerals' exploration team is already on site conducting mapping and early-stage sampling.
Why Investors Should Watch PNN
Power Minerals is strategically positioning itself at the intersection of several powerful market forces:
-
U.S. Critical Minerals Push: The U.S. government is actively supporting domestic rare earth production to reduce dependence on foreign sources, particularly from China.
-
Heavy Rare Earth Advantage: The Power Minerals Gamma Project's high HREE content addresses a critical gap in the U.S. supply chain that even the $20 billion Mountain Pass operation doesn't fill.
-
Dual Commodity Potential: With both high-grade rare earth and uranium mineralisation, the project offers exposure to two critical mineral markets from a single asset.
-
Strategic Location: Proximity to the Mountain Pass Mine creates potential synergies, including possible HREE feedstock supply to the existing operation.
-
Experienced Backers: The investment by institutional players like Tribeca Investment Partners validates the project's potential.
The acquisition of the Gamma Heavy Rare Earths Project transforms Power Minerals' portfolio, complementing its existing Santa Anna carbonatite project in Brazil and positioning the company as an emerging player in the global critical minerals market.
For investors seeking exposure to the rare earths sector, Power Minerals offers an entry point into a high-potential project at an early stage, backed by institutional investment and led by a management team focused on rapidly advancing exploration to capitalise on strong market fundamentals.
