Highlights

Both maiden diamond drillholes at Avondschaduw (AD001 and AD002) completed for a combined 866.20 metres, intersecting broad sulphide mineralisation.
AD001 intersected 19 silicified felsic dykes and strongly altered syenogranite hosting recurring zones of pyrrhotite, pyrite, and chalcopyrite.
AD002 intersected a continuous 41.80-metre main sulphide zone (182.70–224.50m) coinciding with the Line 6200 IP chargeability peak, plus visible chalcopyrite at 62.60m.
AD001 half-core samples delivered to laboratory in Otjiwarongo, Namibia, for gold and multi-element assay. AD002 samples are being prepared.
Drill rig relocating to Kameelburg flagship project to drill three follow-up holes targeting high-grade niobium mineralisation.

Aldoro Resources Limited (ASX:ARN) has completed its maiden two-hole diamond drilling programme at the Avondschaduw copper-gold prospect in central Namibia, with both drillholes intersecting broad zones of hydrothermally altered host rocks and visible sulphide mineralisation across a 700-metre strike corridor. The results confirm that the IP chargeability anomalies targeted by the drilling correspond to genuine bedrock sulphide systems, validating the Company's systematic geophysical approach to new discovery identification.

Latest Development

Drillhole AD001, completed on IP Line 5500 to a final depth of 532.70 metres, intersected a composite package of silicified, sericite-altered felsic dykes and altered syenogranite exceeding 250 metres in combined downhole thickness. Within this altered package, visual inspection identified recurring zones of disseminated, fracture-hosted, and blebby pyrrhotite and pyrite, with chalcopyrite intersected at 334.10–335.00 metres. Drillhole AD002, completed 700 metres to the east on IP Line 6200 to 333.50 metres, intersected multiple sulphide-bearing intervals including visible chalcopyrite at 62.60 metres, coarse blebby pyrrhotite bands at 164.10–164.70 metres, and a continuous 41.80-metre main sulphide zone between 182.70 and 224.50 metres that directly coincides with the Line 6200 IP chargeability peak modelled at approximately 190–200 metres apparent depth. All 47 half-core samples from AD001 have been delivered to the laboratory in Otjiwarongo for analysis, while 62 samples from AD002 are being prepared on site.

Company Background

Aldoro Resources holds an 85% contractual interest in three exploration permits (EPL 7372, EPL 7373, EPL 7895) through Kameelburg Exploration and Mining Pty Ltd in central Namibia. The Company's flagship Kameelburg Project is focused on niobium mineralisation, with drilling at the DD003 pad targeting high-grade niobium now being prepared as the rig demobilises from Avondschaduw. Avondschaduw was designated as a copper-gold reconnaissance target based on regional airborne magnetic data and subsequently characterised through intermediate-gradient IP and sounding surveys, which identified distinct chargeability anomalies as the primary drill targets.

Sector Context

Namibia's Damara Belt is a Neoproterozoic metamorphic and igneous terrane that has historically produced significant base metal and industrial mineral deposits. The Central Zone of the Damara Belt, where the Avondschaduw prospect is located, hosts metasedimentary rocks and granitoids beneath partial surficial cover. Sulphide systems in this environment can represent copper-gold skarn, intrusion-related copper-gold, or base metal massive sulphide systems, depending on the relationship between intrusive activity and regional structures. The 700-metre strike extent confirmed by this maiden drilling programme provides a meaningful footprint for follow-up systematic exploration.

Market Perception

The confirmation that both IP anomalies correspond to genuine bedrock sulphide systems is an important validation of the Company's geophysical targeting approach. For exploration-stage companies, the first step in converting geophysical targets into drilled intercepts is methodologically critical: a 700-metre corridor of sulphide-bearing alteration in both holes, with chalcopyrite present in each, provides geological coherence that justifies assay follow-up and potential extensional drilling. Visual sulphide observations are inherently qualitative and cannot be used as a proxy for laboratory grades, but the geological consistency between the two widely spaced holes is an encouraging indicator of system scale.

Growth Drivers

The Avondschaduw prospect benefits from the operational efficiency of Aldoro's established in-country team and existing drill rig infrastructure, which allows the Company to advance both the copper-gold and niobium programmes without duplicating overhead costs. The 700-metre corridor is entirely open along strike and at depth, providing a substantial exploration frontier. The return of assay results from the laboratory is the next data-driven catalyst, and the integration of assay data with detailed geological logging and the IP geophysical model will guide any follow-up drill targeting. The Company's niobium programme at Kameelburg meanwhile represents an independent value pathway.

Risks and Challenges

Visual assessment of sulphide mineralogy is not a substitute for laboratory chemical analysis, and no grade estimates have been made or reported from the Avondschaduw holes. The relationship between the observed sulphide assemblages — dominated by pyrrhotite and pyrite with subordinate chalcopyrite — and any gold mineralisation will only be established from laboratory assays. The pyrrhotite-dominant system seen in both holes is a less direct copper indicator than massive chalcopyrite, and the distinction between iron sulphides and economic copper-gold concentrations requires analytical confirmation. Down-hole surveys in both holes were also limited due to the magnetic interference from magnetite in the host rocks. Laboratory turnaround time for the Otjiwarongo Facility is an additional timing consideration.

Recent Announcements

The IP survey results defining the chargeability anomalies were previously reported in October 2026, alongside drillhole commencement. The Company has previously reported niobium drilling results at Kameelburg, with three follow-up holes now planned to target the high-grade niobium zones identified in prior campaigns.

Key Insights

Aldoro Resources has successfully completed its maiden two-hole reconnaissance programme at Avondschaduw, confirming a 700-metre strike of sulphide-bearing hydrothermal alteration in the central Damara Belt of Namibia. With chalcopyrite intersected in both holes and a 41.80-metre main sulphide zone in AD002 coinciding precisely with the IP chargeability target, the geological framework is in place for assay-based evaluation of the system's copper-gold potential. The rig is now returning to the flagship Kameelburg niobium project, maintaining dual exploration momentum across the portfolio.

FAQs

Q: What type of mineralisation was intersected at Avondschaduw?

A: Both drillholes intersected broad hydrothermal alteration zones containing disseminated to blebby pyrrhotite, pyrite, and chalcopyrite. The relationship between the iron sulphide system and economic copper-gold grades will be established from laboratory assays.

Q: How far apart were the two drillholes?

A: AD001 and AD002 were drilled 700 metres apart along strike, on separate IP geophysical lines (5500 and 6200), confirming system continuity across this distance.

Q: What geophysical method was used to identify the drill targets?

A: Intermediate-gradient IP (induced polarisation) surveys were conducted to identify chargeability anomalies in the subsurface. The main sulphide zone in AD002 coincides directly with the IP chargeability peak, validating the geophysical targeting approach.

Q: When will assay results be available?

A: AD001 core samples have been delivered to the laboratory in Otjiwarongo, Namibia. AD002 samples are being prepared for dispatch. Laboratory turnaround times in Namibia will determine when results are released to the market.

Q: What is the Kameelburg Project focused on?

A: The Kameelburg flagship project is focused on niobium mineralisation. The drill rig has now been relocated from Avondschaduw back to Kameelburg to test three follow-up holes targeting high-grade niobium zones.
