Arkle Resources PLC, the London-listed energy metals explorer, has completed airborne and ground-based geophysical surveys across its uranium projects in Namibia’s Erongo Region.
The work forms part of Phase 1 of the company’s exploration programme following its January 2026 acquisition of four exclusive prospecting licences covering 540 km².
“We are delighted with the rapid progress of the geophysical surveys and the initial findings from the HLEM work. The identification of a deep new palaeochannel has positive implications for the target geology,” said interim chief executive officer Rory Harding.
The surveys, conducted by Xcalibur Smart Mapping and Terratec Geophysical Services Namibia, included horizontal loop electromagnetic (HLEM) work, alongside magnetic and radiometric airborne mapping covering more than 12,000 line kilometres.
The high-resolution data, four times denser than historical datasets from the 1970s, confirmed a well-developed palaeochannel in the north-east of EPL 8995 and identified a previously unknown palaeochannel in the centre of the licence, reaching depths of up to 17 metres.
A review of historical drilling also identified 95 open drill holes suitable for downhole gamma logging. These findings, together with a 2025 sampling programme that recorded surface uranium values of up to 3,855 ppm U₃O₈, will guide follow-up mapping and sampling, as well as the development of drill targets for up to 4,000 metres of reverse circulation (RC) drilling planned for the second half of 2026.
Arkle’s licences are located near some of Namibia’s largest uranium deposits, including Trekkopje, Marenica and Rössing, placing the company within one of Africa’s most productive uranium belts. The region has produced more than 350 million pounds of U₃O₈ over the past 45 years.
“We now look forward to analysing the Xcalibur data ahead of the mapping programme in the coming months. The next phase of geophysical interpretation, mapping and sampling will guide the development of drill targets,” Harding said.
