Aldoro Extends Kameelburg Rare Earths and Strontium Mineralisation with 354m Intercept

354m Northwest Extension Confirms Deposit Growth

Aldoro Resources Ltd (ASX:ARN) has expanded the footprint of its Kameelburg rare earth elements (REE), strontium (Sr), niobium (Nb), and molybdenum (Mo) deposit in Namibia with the latest assay results from diamond drill hole DD004F. The hole intersected 354.2 meters of continuous mineralisation, extending the known mineralised zone northwest from the DD004 drill pad. Although the hole did not reach the interpreted deep high-grade REE-Sr core, the mineralisation remains open at depth, underscoring the potential for further resource growth.

Significant intercepts include near-surface zones such as 57 meters grading 1.85% total rare earth oxides (TREO) and 5.56% SrCO3, highlighting strontium as a valuable co-product alongside the REEs. Strontium carbonate, a critical input for permanent magnets and electronics, has been confirmed in broad zones exceeding 5%, systematically occurring with elevated TREO within the central carbonatite.

Mineralisation Characteristics and Drilling Insights

DD004F was drilled at an azimuth of 310° northwest and a dip of -60°, targeting the northwest structural corridor of the Kameelburg carbonatite. The hole intersected multiple mineralised zones dominated by beforsite, an iron-rich mafic phase, which typically exhibits lower TREO grades compared to the sovite core but sustains elevated niobium and molybdenum concentrations. This lithological control on mineralisation aligns with previous drilling results, including those from DD004D and DD004E.

Notably, a 74-meter iron ore zone averaging 30% Fe was intersected in nearby DD004D, presenting a potential co-product opportunity that could enhance the project's economics. The company has also completed drilling of DD008G, which aims to test the interpreted deep mineralisation centre guided by grade-depth trends from the DD004 pad.

Phase II Drilling Complete, Bulk Sampling Next

The Phase II drilling program at Kameelburg has wrapped up with 15 diamond drill holes totaling 7,190 meters. Additional assay results are expected throughout April and May, feeding into an updated Mineral Resource Estimate (MRE) that will incorporate recent findings, including strontium and iron content. This updated MRE is anticipated within the next two weeks and will refine the project's resource confidence and scale.

Following drilling, Aldoro plans to deploy its Smart 8 drilling rig to commence bulk sampling across the carbonatite, a critical step toward advancing metallurgical testing and economic studies. The ongoing work builds on a series of substantial intercepts, including the 387-meter continuous mineralisation in DD004E earlier this month, which similarly confirmed extensive REE-Sr-Nb mineralisation and set the stage for bulk sampling activities 387m continuous mineralisation.

Critical Minerals in a Strategic Location

Kameelburg is situated in Namibia’s northern Central Damara Orogenic Belt and is characterised by a 1.4-kilometer diameter carbonatite plug with associated radial dykes. The deposit hosts a complex mineral assemblage with rare earth minerals like ancylite and significant niobium and molybdenum, alongside the newly emphasised strontium carbonate. The deposit’s mineralisation style draws parallels with the Niobec Sant Honore deposit in Canada, a well-known source of critical minerals.

With global supply chains for rare earths and strontium under pressure, Kameelburg’s growing resource base places Aldoro in a strong position within the critical minerals sector. The confirmation of broad, high-grade zones near surface and at depth, alongside potential iron ore by-products, enhances the project's multi-commodity appeal.
