ReeXploration Inc. has identified a series of significant, previously untested magnetic anomalies at its flagship Eureka Rare Earth Project in Namibia’s Erongo Region, suggesting the mineralising system could be significantly larger than previously understood.
The discovery points to deeper, potentially carbonatite-hosted bodies that could expand the project’s rare earth resource base and bolster Namibia’s growing role in global critical minerals supply.
According to the Halifax-based company, analysis of newly modelled magnetic data has revealed multiple high-magnetic features extending over a 5-kilometre strike length along the northwestern flank of the Eureka Dome.
These magnetic bodies, interpreted to begin at depths of 50–100 metres, align with major structural lineaments believed to have channelled mineralising fluids.
Tolene Kruger, Senior Geologist at ReeXploration, said the integration of surface geology with magnetic data modelling reveals structural complexity beneath Eureka, suggesting a potentially larger mineralising system. She added that the interpreted magnetic bodies could represent feeder zones for the rare-earth mineralisation discovered at the surface.
Further characterising their nature through upcoming ground gravity surveys will be an essential step in refining targets ahead of drill testing.
Eureka currently 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 and praseodymium oxides, based on 19 drill holes completed across Zones 1–3. The mineralisation is hosted within monazite-bearing carbonatite, a favourable mineral type known for its low impurity levels and ease of processing.
Interim CEO Chris Drysdale described the new findings as transformative, saying Eureka continues to stand out as a strategically positioned rare earth project with favourable metallurgy, a strong jurisdiction, and growing potential scale.
He added that the newly defined magnetic targets strengthen the company’s view that Eureka hosts a much larger rare earth system, a goal well aligned with the global drive to secure sustainable NdPr supply.
ReeXploration’s 3D magnetic modelling, based on high-resolution surveys conducted by Remote Exploration Services, indicates that the newly detected magnetic anomalies may represent carbonatite intrusions.
The same rock type hosts world-class rare-earth deposits elsewhere in Africa.
A planned gravity survey will now test for corresponding density variations to validate these geophysical interpretations before drilling begins.
Radiometric data also highlight zones of low potassium coincident with calcrete cover, which may conceal additional carbonatite bodies beneath surface sediments. Together, the datasets point to substantial unexplored potential across the 13-by-6-kilometre Eureka Dome.
Early metallurgical testing has produced a 60% TREO concentrate through simple gravity and magnetic separation, confirming the project’s technical viability.
With neodymium (Nd) and praseodymium (Pr)—essential components in electric vehicle motors, wind turbines, and defence systems—driving global demand, Eureka positions Namibia as a key player in the emerging clean-energy minerals economy.
Namibia’s transparent regulatory framework and established infrastructure make it one of Africa’s most attractive destinations for rare earth exploration.
Projects like Eureka complement the country’s Green Industrialisation Blueprint, which aims to develop downstream value chains for critical minerals.
As ReeXploration advances toward its next discovery phase, upcoming gravity surveys and drill testing will determine whether Eureka’s deep magnetic features conceal the next primary African source of sustainable magnet metals.
