Eureka Rare Earth Project

Project Overview

The Eureka REE Project is ReeXploration’s flagship rare earth element (REE) project in Namibia, one of Africa’s most established and mining-friendly jurisdictions. Located in the heart of the Erongo Mining District, the Project is located just 2 km from the Trans-Kalahari Highway, providing direct access to the capital Windhoek and the deep-water port of Walvis Bay. A major powerline and rail system also runs immediately south of the Project. 

Prime Location in the Erongo Mining District

Established Resource Base

The Project is underpinned by a maiden NI 43-101 resource (2021) of 310,000 tonnes @ 4.8% TREO (including 0.7% Nd+Pr oxides)* from the initial 19 drill holes (613 metres) completed across Zones 1-3. Neodymium (Nd) and Praseodymium (Pr) are the primary drivers of value, essential for permanent magnets used in EVs, renewable energy systems, and defense technologies.

Geology & Mineralization

  • District-scale REE mineral system recognized across the Eureka Dome
  • REE mineralization hosted in monazite-bearing carbonatite, a favourable mineralogy recognized for low impurities, low radioactivity, and compatibility with Western processing standards
  • Fourteen initial carbonatite dykes identified across three zones (Zone 1-3); thickness ranges 0.5–5 m, open along strike and depth
  • Early metallurgical testwork has already produced a concentrate with ~60% TREO after gravity and magnetic separation, confirming processability and de-risking technical risk at an early stage

Exploration & Growth

District-Scale Discovery Opportunity

Covering approximately 13 by 6 kilometres, the Eureka Dome hosts a district-scale rare earth element (REE) mineral system. Exploration to date has revealed shallow, high-quality mineralization that points to the potential for a much larger underlying system.

Innovative Exploration Revealing Hidden Potential

Historically, thin surficial cover has concealed this opportunity, but the Company’s innovative and cost-effective exploration methodologies are now unlocking the area’s true potential. With a systematic, staged approach delivering consistent growth signals, Eureka is emerging as a significant rare earth project with potential to significantly expand the resource base through continued exploration.

Trenching
Expanding the Near-Surface Footprint
Trenching has proven to be a highly effective, low-cost tool for uncovering shallow rare earth mineralization concealed beneath thin soil and calcrete/gypcrete cover. Results have been exceptionally encouraging — 18 of 19 trenches excavated across priority targets within the Eureka Dome (Zones 1 & 2, Adder, Boxer, Clover, Dakota, and Easton) have intersected REE mineralization, confirming the continuity and scale of the system near surface. Samples are now pending laboratory assay.
Soil Sampling
Mapping the Mineral System
More than ten discrete lanthanum (La) and cerium (Ce) soil anomalies have been identified across the Eureka Dome. Previous work at Eureka has demonstrated that La and Ce values—and their combined response—are effective pathfinders for identifying monazite-hosted REE mineralization beneath thin soil cover. Soil sampling is ongoing, following a systematic grid to expand coverage across the Dome and define additional zones of potential REE mineralization for follow-up trenching and drilling.
Geophysics
Defining a Pipeline of Growth Targets
High-resolution radiometric, UAV, and ground magnetic surveys have been instrumental in mapping the structural and lithological controls on mineralization and in generating a pipeline of high-priority drill targets across the Dome. The correlation between geophysical anomalies and mineralized zones provides strong validation for the Company’s exploration model. Additional surveys are planned to refine and expand target areas, laying the groundwork for systematic discovery and resource growth.
Drilling
Advancing Toward Resource Definition
To date, four phases of drilling have been completed using both reverse-circulation (RC) and diamond core methods to optimize cost and geological understanding. Drilling has confirmed continuity of mineralization across multiple zones and identified open extensions that remain untested. With a growing inventory of high-priority targets, follow-up drilling is planned to extend known mineralization and advance Eureka toward initial resource definition.

Technical Advantage

ReeXploration follows a metallurgy-first approach, validating process performance early to de-risk development. Initial bench-scale metallurgical testing by SGS Mineral Services (2021) confirmed that simple gravity and magnetic separation can produce a high-grade, clean monazite concentrate:

  • Concentrate Grade: ~59 % Total Rare Earth Oxides (TREO)
  • Recovery: ~65 % TREO at ~10 % mass pull
  • Key Elements: High in neodymium (Nd) and praseodymium (Pr), essential for permanent magnet production
  • Radionuclides: Very low thorium (~0.45 %) and uranium (~0.01 %), yielding a specific activity of only ~18.7 Bq/g — well below levels that complicate transport or permitting.

SGS recommends minor circuit optimization (regrind and scavenger-cleaner improvements) to enhance recoveries, while confirmatory testing by Actlabs and Bond Equipment further validated the results and support flowsheet scalability.

This early metallurgical success confirms that Eureka’s mineralization can yield a saleable, low-radioactivity concentrate using straightforward, low-cost gravity and magnetic processing.

By proving processability at the outset, ReeXploration has reduced technical risk, validated commercial potential, and can now focus on scaling the resource base across the broader Eureka Dome.
