Aldoro Resources Reports Exceptional Niobium and Strontium Grades Expanding Kameelburg Scale

Mining By Maxwell Dee 4 min read

Aldoro Resources has unveiled standout high-grade niobium and strontium intercepts from its Phase II drilling at Kameelburg, Namibia, confirming a large, continuous multi-commodity mineral system and opening a potential standalone niobium domain.

  • High-grade niobium intercepts redefine northern flank potential
  • Strontium carbonate confirmed as major secondary commodity
  • Phase II drilling complete with 15 holes for 7,190m
  • Mineralisation open in all directions with follow-up drilling planned
  • Updated Mineral Resource Estimate to include strontium carbonate

High-Grade Niobium Intercepts Reshape Kameelburg's Northern Flank

Aldoro Resources (ASX:ARN) has delivered a compelling update from its flagship Kameelburg REE-Niobium Project in Namibia, revealing exceptional niobium grades that could transform the project's economic profile. Drill hole DD003A on the northern flank returned a remarkable 11 metres at 0.76% Nb2O5 starting at 102 metres, a grade considered exceptional by global industry standards. This was supported by further significant intercepts of 5.8 metres at 0.43% Nb2O5 and 31 metres at 0.32% Nb2O5 at greater depths, establishing the northern area as a potentially standalone high-grade niobium domain.

Niobium’s critical role in high-strength steels, superalloys, and emerging battery technologies underlines the strategic importance of these findings. The discovery of such grades on the northern flank adds a new dimension to Kameelburg’s resource potential, complementing the existing rare earth and strontium mineralisation.

Strontium Carbonate Emerges as a Significant Co-Commodity

Alongside niobium, strontium carbonate (SrCO3) continues to assert itself as a major secondary commodity at Kameelburg. Both DD003A and DD018A holes returned broad zones with strontium carbonate grades exceeding 3%, often associated with elevated total rare earth oxides (TREO). Notably, DD003A delivered a near-surface bonanza-style intercept of 5 metres at 7.64% SrCO3 and 2.94% TREO, among the highest combined grades recorded at the complex.

Strontium is a critical input for permanent magnets and electronics, and Aldoro’s recent metallurgical testwork has demonstrated nearly 99% strontium extraction efficiency, reinforcing the project's dual-commodity appeal. This positions Kameelburg as a rare, low-complexity source amid global supply shocks and soaring strontium prices, a dynamic explored in recent nearly 99% strontium recovery results.

Southern Margin Confirmed with Extensive Stacked Mineralisation

DD018A, drilled on the southern margin, confirmed 74 metres of cumulative mineralisation across two stacked layers. The upper layer returned 23 metres at 0.98% TREO, 4.19% SrCO3, and 0.08% Nb2O5, consistent with sovite-dominated mineralisation. Below, a 51-metre intercept at 0.70% TREO, 3.10% SrCO3, and 0.32% Nb2O5 marked a transition into niobium-enriched beforsite mineralisation.

This two-layer architecture mirrors the carbonatite stratigraphy observed elsewhere and confirms robust mineralisation continuity southwards. Both layers remain open along strike and at depth, reinforcing the deposit's scale potential.

Deposit Scale and Continuity Reinforced by Magnetic Survey

The Kameelburg carbonatite is defined by a coherent ~1.4 km2 magnetic high, with the strongest magnetic responses aligning with the high-grade central core and extending beyond current drilling. Both DD003A and DD018A lie well within this anomaly, indicating significant scope to extend mineralisation footprints in all directions. This magnetic signature supports the interpretation that the mineralised system remains open and expansive.

These findings build on prior drilling success, including a 354.2-metre continuous rare earth and strontium intercept reported in 354m intercept extension, and a 387.2-metre continuous mineralisation in DD004E highlighted in 387m continuous mineralisation, underscoring the deposit's impressive scale.

Next Steps: Resource Update, Deeper Drilling and Bulk Sampling

With the completion of Phase II drilling, 15 holes totaling 7,190 metres, Aldoro is advancing rapidly toward an updated Mineral Resource Estimate (MRE) that will incorporate strontium carbonate for the first time, materially expanding the project's value envelope. This update is expected in the coming weeks and will be critical for refining the economic outlook.

Encouraged by a clear grade-with-depth trend at DD003A, where REE and SrCO3 grades increase below 200 metres, Aldoro has prioritised a follow-up deeper hole on the DD003 pad to test this high-conviction target. Concurrently, the company is mobilising its Smart 8 drilling rig to commence bulk sampling, accelerating metallurgical testwork and advancing toward definitive studies.

These developments follow earlier confirmation of continuous rare earth and niobium mineralisation across the carbonatite system, as detailed in extensive REE mineralisation confirmation, reflecting a multi-commodity strategy that positions Kameelburg as a critical minerals hub in Namibia.

Bottom Line?

The exceptional niobium grades and robust strontium continuity at Kameelburg expand the project's scope, but upcoming resource updates and deeper drilling will be pivotal in defining its economic potential.

Questions in the middle?

  • How will the inclusion of strontium carbonate in the updated MRE alter the project's valuation?
  • Can the northern niobium domain sustain standalone economic viability independent of rare earths?
  • What metallurgical challenges might arise from the multi-commodity nature of the deposit?
