ReeXploration Uncovers Potential for Rare Earth Expansion at Eureka

ReeXploration Inc. has announced significant findings from its Eureka Project in the Erongo Region of Namibia, suggesting the potential for a broader rare earth element (REE) system. The company revealed on November 4, 2025, that a detailed analysis of geophysical data has identified large magnetic features that had previously gone untested. These findings indicate that the mineralization system at Eureka could be more extensive than previously defined.

The newly uncovered magnetic features, which span a 5 km strike length along the northwestern flank of the Eureka Dome, may represent deeper intrusive bodies linked to the existing shallow REE mineralization. The Project hosts a maiden NI 43-101 Inferred Mineral Resource Estimate of 310,000 tonnes at 4.8% Total Rare Earth Oxides (TREO), including 0.7% neodymium (Nd) and praseodymium (Pr) oxides, both essential for low carbon technologies.

Key Findings and Next Steps

The analysis indicates that these magnetic bodies could be intrusive carbonatites, which are known to host REE mineralization. At least one carbonatite phase on the project has been identified as highly magnetic, supporting the interpretation that these features could be indicators of further REE deposits. Additionally, the convergence of these magnetic features with potential feeder structures highlights possible pathways for mineralizing fluids.

The potential for discovery is bolstered by the presence of multiple near-surface exploration targets, which include a large REE soil anomaly identified near the southern flank of the Eureka Dome. ReeXploration plans to conduct a gravity survey to assess the size and density of the magnetic bodies before drilling commences to further evaluate the REE mineralization and resource expansion potential.

Tolene Kruger, Senior Geologist for ReeXploration, emphasized the significance of the integration of surface geology with magnetic data modeling. She stated, “These interpreted magnetic bodies could represent feeder zones to the rare earth mineralization discovered at surface. Further characterizing their nature through upcoming ground gravity surveys will be an important step in refining targets ahead of drill testing.”

Interim CEO Chris Drysdale noted that Eureka is strategically positioned within a favorable jurisdiction, enhancing its potential scale. He expressed confidence that the newly defined magnetic targets indicate a larger REE system, aligning with the global drive to secure sustainable sources of NdPr supply.

Market Context and Strategic Importance

The project’s early metallurgical testing confirmed that the known REE mineralization is hosted in monazite-bearing carbonatite. This mineralogy is recognized for its low impurities and compatibility with Western processing standards. Testing has already yielded a concentrate with approximately 60% TREO following gravity and magnetic separation, showcasing its processability and reducing technical risks.

Neodymium and praseodymium are critical for permanent magnets used in electric vehicles, renewable energy systems, and defense technologies. Global demand for these REE oxides is surging as governments prioritize secure and sustainable supply chains for critical minerals. The stable and infrastructure-rich environment of Namibia positions projects like Eureka to diversify the global supply of responsibly produced magnet-metal feed.

In summary, the interpretation of high-resolution ground magnetic data from 2022 suggests significant unexplored potential within the 13 x 6 km Eureka Dome. The presence of magnetic bodies indicates deeper structures that may enhance the existing REE mineralization. ReeXploration is preparing to advance toward the next phase of discovery, with plans for gravity surveys to further refine drilling targets.

As ReeXploration moves forward, the company is poised to play a vital role in meeting the increasing global demand for rare earth elements, contributing to a sustainable and secure supply chain in the critical minerals sector.
