Key Highlights

  • Both maiden holes, AD001 and AD002, were completed for a combined 866.20m at the Avondschaduw prospect.
  • Visible pyrrhotite, pyrite and chalcopyrite were logged in both holes at depths predicted by the 2026 IP survey.
  • AD002 logged a 41.80m main sulphide zone between 182.70m and 224.50m, coinciding with an IP chargeability peak.
  • No laboratory assay results have been reported yet, and visual estimates are not a substitute for grade.

Aldoro Resources Limited (ASX:ARN) has completed a maiden two-hole diamond drilling program at its Avondschaduw copper-gold prospect in Namibia, located northeast of the flagship Kameelburg project in the Damara Belt. The update dated 11 November 2026 reports that both holes intersected hydrothermally altered rock and visible sulphides at the depths predicted by the company’s 2026 induced polarisation survey, although no laboratory assays have been released yet.

What the two holes intersected

Hole AD001 was drilled to 532.70m on IP line 5500 and intersected a package of silicified felsic dykes and altered syenogranite that exceeds 250m in combined thickness. Within it, the company logged 19 silicified dykes with a cumulative thickness of 131.78m. Visible chalcopyrite intergrown with pyrrhotite was logged at 334.10 to 335.00m, with visual sulphides estimated at about 1%, and the hole also contained disseminated magnetite at depth.

Hole AD002 was drilled 700m east on IP line 6200 to 333.50m. It returned visible chalcopyrite at 62.60m, semi-massive pyrrhotite bands between 164.10m and 164.70m, and a 41.80m main sulphide zone from 182.70m to 224.50m. The company estimates visual sulphides in that zone at 3 to 5% on average, locally 5 to 10%, in syenogranite with quartz veins and intense sericite-chlorite alteration.

How the drilling tests the geophysics

Both holes were designed to test IP chargeability anomalies and were drilled towards an azimuth of 180 degrees at dips of -85 and -80 degrees. The company said the main AD002 sulphide zone coincides with the chargeability peak modelled at about 190 to 200m apparent depth, and that AD001 accounts for the deep-seated chargeability anomaly on line 5500.

The company was careful to describe its observations as visual and preliminary. Visual sulphide estimates do not indicate metal concentrations or grades, and the reconnaissance spacing of 700m between the holes is too wide for resource estimation. True widths of the mineralised zones are not yet established, and the reported intervals are downhole lengths.

Samples, tenure and what comes next

Core from AD001 has been cut into 47 half-core samples across 13 intervals and delivered to a laboratory in Otjiwarongo for gold and multi-element analysis. Samples from AD002 have been cut and prepared on site, with 62 samples across 11 intervals ready for dispatch. The Avondschaduw tenement, EPL 7895, is held by Kameelburg Exploration and Mining Pty Ltd, in which Aldoro holds an 85% contractual interest.

With both reconnaissance holes complete, the drill rig is moving back to the DD003 pad at Kameelburg to drill three follow-up holes targeting high-grade niobium mineralisation. Assay results from Avondschaduw will be integrated with the geological and geophysical datasets to guide the next phase of exploration along the copper-gold corridor.

Final Word

The Avondschaduw drilling confirms that the geophysical targets correspond to sulphide-bearing rock, which is the first step in testing whether the system carries economic metal. The laboratory results and the follow-up program will determine whether the visible mineralisation translates into grade and whether the corridor can support further drilling. Until assays are released, the economic significance of the intersections remains unknown.
