Axel REE Uncovers Extensive High-Grade Gallium Zones at Caladão Project
Axel REE Limited (ASX: AXL) has reported consistent high-grade gallium intercepts from its ongoing exploration program at the Caladão Project in Minas Gerais, Brazil. The latest assay results confirm extensive gallium mineralization at shallow depths with significant lateral continuity, highlighting Area B as a standout target for potentially defining a large high-grade gallium resource.
Impressive Drill Results Reveal Shallow Gallium Mineralization
The latest auger drilling campaign has delivered multiple high-grade gallium intercepts, with most mineralization starting directly at surface:
- CLD-AUG-464: 9m @ 86g/t Ga₂O₃ from surface (including 4m @ 95g/t Ga₂O₃)
- CLD-AUG-468: 15m @ 83g/t Ga₂O₃ from surface (including 2m @ 106g/t Ga₂O₃)
- CLD-AUG-418: 5m @ 79g/t Ga₂O₃ from surface (including 3m @ 85g/t Ga₂O₃)
- CLD-AUG-477: 19m @ 74g/t Ga₂O₃ from surface (including 5m @ 85g/t Ga₂O₃)
- CLD-AUG-474: 10m @ 74g/t Ga₂O₃ from surface (including 3m @ 81g/t Ga₂O₃)
These results demonstrate consistent grade distribution across the target area and reveal significant potential for a large-scale, near-surface gallium resource. The Axel Ree gallium discovery is particularly notable for its continuity and grade consistency.
In addition to gallium mineralization, the program also encountered several high-grade rare earth element (REE) intercepts, including:
- CLD-AUG-447: 5m @ 4,801ppm TREO (20% MREO) from 15m (including 1m @ 7,523ppm TREO)
- CLD-AUG-447: 5m @ 3,087ppm TREO (19% MREO) from 9m (including 1m @ 4,771ppm TREO)
The company is now progressing toward a Maiden Gallium and REE Resource at the Caladão Project, with completion expected in July.
Understanding Gallium: A Critical Metal for the Future
Gallium is classified as a critical mineral due to its essential role in semiconductor manufacturing, particularly for chips used in artificial intelligence, 5G networks, and renewable energy technologies. As a byproduct of aluminum and zinc production, dedicated gallium deposits are rare, making Axel's high-grade, near-surface discovery particularly significant.
Traditional gallium supply chains have been heavily concentrated in China, which produces approximately 98% of the world's gallium. Recent export restrictions have heightened global concerns about supply security, driving interest in new sources outside China.
The average grade of gallium in the Earth's crust is extremely low at approximately 19 parts per million, making Axel's consistent intercepts of 70-100 g/t Ga₂O₃ notably high-grade in comparison to typical mineralization. Similar trends have been observed in other regions where high-grade gallium discovery projects are becoming increasingly important to global supply chains.
Key Applications of Gallium
Gallium has several critical applications that make it essential for modern technology:
- Semiconductor Manufacturing: Gallium arsenide (GaAs) and gallium nitride (GaN) are used in high-performance electronic devices.
- LED Technology: Gallium is a crucial component in light-emitting diodes used in displays and lighting.
- Solar Panels: Gallium compounds are used in thin-film photovoltaic cells.
- 5G Infrastructure: Gallium-based semiconductors are essential for high-frequency applications in telecommunications.
- Defense Applications: Used in radar systems, satellite communications, and other military technologies.
The Axel REE gallium discovery could potentially provide a significant new source of this critical mineral outside of traditional supply chains.
Exploration Progress and Future Plans
The drilling program at Caladão has now completed 597 auger holes for a total of 8,449 meters across key target zones. All outstanding samples have been submitted for analysis, with assay results continuing to arrive in sequential batches.
These results will form the foundation for defining a maiden Mineral Resource Estimate at Area B, complementing the upcoming resource estimate for Area A. Together, these resources will demonstrate the scale and strategic potential of the broader Caladão system.
"With auger drilling ongoing at Area B, it's encouraging to see confirmation of broad, shallow zones of gallium and rare earth, consistent with results from Area A. These assay results are significant for Axel as we progress to defining a sizeable, near-surface critical mineral resource.
The Caladão Project continues to exceed expectations, with strong evidence that weathered profile in Area B is enriched with gallium and rare earths, in line with our exploration model. The team's technical work is setting a strong foundation for resource delineation and future development opportunities."
These comments from Non-Executive Chairman Paul Dickson highlight the significance of the Axel REE gallium discovery and the company's strategic approach to resource development.
Geological Context and Project Setting
Located in northeast Minas Gerais, the Caladão Project overlies Neoproterozoic sedimentary sequences punctuated by late-tectonic alkaline intrusions. Intense tropical weathering of the granitic units has produced a saprolite layer with notably high magnetic rare earth element (MREO) grades in Area A.
Meanwhile, Area B's lateritic profile shows consistent, elevated gallium values, evidencing a coherent gallium-rich horizon that warrants systematic drill testing for resource extents. Recent findings from the Tundulu gallium discovery have shown similar mineralization patterns in weathered profiles.
The project geology is particularly favorable for the development of enriched weathering profiles that concentrate both gallium and rare earth elements, creating the potential for economic extraction from near-surface deposits. Furthermore, the presence of rare earth minerals in carbonatite formations has been linked to similar geological settings worldwide.
Why Investors Should Watch Axel REE
Axel REE represents a compelling investment opportunity for several key reasons:
-
Exposure to Critical Minerals: The company provides direct exposure to gallium and rare earth elements—both classified as critical minerals essential for the green energy transition and technological advancement.
-
Near-Surface Mineralization: The shallow nature of the mineralization (starting from surface) suggests potential for low-cost mining operations with minimal stripping requirements.
-
Dual Commodity Potential: The presence of both gallium and rare earth elements creates the possibility for multi-commodity production, potentially enhancing project economics.
-
Strategic Location: Brazil represents a politically stable jurisdiction for mining investments, with established mining codes and infrastructure.
-
Upcoming Catalysts: The imminent maiden resource estimate represents a significant value-defining milestone that could drive market revaluation.
As global technology manufacturers seek to secure supply chains for critical minerals outside of China, projects like Caladão offer strategic importance. With gallium's crucial role in semiconductor manufacturing and renewable energy applications, the Axel REE gallium discovery positions the company to potentially become a significant supplier in an increasingly tight market.
The combination of shallow mineralization, consistent high grades, and progress toward resource definition makes Axel REE one to watch as it advances the Caladão Project toward development. Investors interested in critical minerals might also follow developments in complementary sectors such as gold exploration projects that often share similar jurisdictional advantages.
