Aldoro Resources is investigating two underground targets at its Avondschaduw prospect near Kalkfeld, including a deeper anomaly identified beyond 450 metres, as the Australian-listed explorer seeks to establish whether geophysical indications point to copper-gold mineralisation.
The targets, situated within Exclusive Prospecting Licence 7895 in Namibia’s Damara Belt, were identified through electrical and magnetic surveys that revealed characteristics consistent with possible sulphide mineralisation.
According to the company’s 19 October 2026 announcement, the deeper target will be tested by a 680-metre diamond drill hole, AD001, which is already underway.
A second hole, AD002, is planned to reach 400 metres and investigate a separate anomaly detected at an apparent depth of approximately 190 to 200 metres.
The distinction between the two targets is significant because they represent different underground geophysical responses that Aldoro is seeking to test for potential volcanogenic massive sulphide (VMS) copper-gold mineralisation.
What the surveys revealed
The targets were identified following an induced polarisation survey covering 8.76 square kilometres, involving 34 survey lines and 2,252 measurement stations.
Six additional survey lines were completed across two priority corridors, allowing the company to investigate the depth and characteristics of the anomalies.
The western target, which is being tested by AD001, displays increasing electrical chargeability below an apparent depth of approximately 450 metres, accompanied by declining resistivity.
The eastern target, to be tested by AD002, shows a shallower chargeability peak at approximately 190 to 200 metres, with lower resistivity recorded deeper in the survey profile.
Aldoro said ground magnetic surveys also identified magnetic lows associated with the targets, which it interprets as possible evidence of hydrothermal alteration.
Such characteristics can be associated with sulphide mineralisation, although geophysical anomalies alone cannot confirm the presence of copper, gold or an economically viable deposit.
The drilling is intended to establish the geological explanation for these responses.
Results expected in 2027
Aldoro executive chair Quinn Lee said the targets had been selected following ground magnetic and induced polarisation surveys.
“Following ground magnetic and IP surveys across the prospect, our technical team has delineated two priority chargeability anomalies supported by strong structural features,” Lee said.
The company will examine the recovered drill core to identify the host rocks, alteration patterns and any sulphide mineralisation encountered.
The second hole will follow completion of the first, with laboratory assay results expected during the first quarter of 2027.
Avondschaduw lies southeast of Nordenberg and northeast of Aldoro’s Kameelburg project, within the Central Zone of the Damara Belt.
The wider geophysical survey extended across three adjoining exploration licences, EPL 7372, EPL 7373 and EPL 7895, although both drill holes are located within EPL 7895.
