AuKing Mining Limited (ASX:AKN) has commenced exploration targeting at its Machinga Heavy Rare Earths Project in Malawi, covering a 200.4 km² licence area, with field activities planned and a UAV-based geophysical survey targeted for early December 2026, subject to contractor availability and operational approvals.

Key Points

  • Exploration targeting is underway at the Machinga Heavy Rare Earths Project in Malawi across a 200.4 km² licence area, focused on identifying high-priority heavy rare earth targets.
  • AuKing holds a 100% interest in Machinga following the completion of its acquisition of Green Exploration Limited.
  • Historical drilling returned an average of 29% HREO/TREO and 3.6% DyTb/TREO in mineralised samples above a 0.25% TREO cut-off.
  • S&P Global reported on 30 September 2026 that North American dysprosium oxide prices increased by approximately 41% to US$3,250/kg, while terbium oxide prices surged by approximately 53% to US$7,500/kg.
  • Chinese customs data released 21 September 2026 showed exports of dysprosium and terbium fell to zero in August 2026.

Machinga Project Exploration Targeting and Priority Areas

AuKing has advanced the compilation, validation and interpretation of historical drilling, geochemical and geophysical datasets at Machinga, establishing an improved geological framework to guide systematic exploration targeting. The integrated review has identified multiple priority areas of interest associated with regional radiometric anomalies, interpreted structural corridors and prospective geological settings. These areas remain largely untested by historical drilling and surface sampling. The company's technical team has identified alkaline granitic and pegmatitic lithologies spatially associated with interpreted structural trends and elevated uranium radiometric responses, providing an initial framework for evaluating the distribution of REE–Nb mineralisation.

Historical Drilling Results at Machinga

Historical near-surface drilling at Machinga recorded significant intersections enriched in dysprosium and terbium. Notable results include MDD007 returning 15.1 metres at 1.01% TREO and 27.70% HREO from 23.9 metres, including 4 metres at 1.75% TREO from 33 metres. MDD008 recorded 9 metres at 1.11% TREO and 27.58% HREO from 41 metres. MDD006 returned 5.2 metres at 1.61% TREO and 30.66% HREO from 41.4 metres, including 1 metre at 2.67% TREO from 44 metres. MR005 recorded 16 metres at 1.01% TREO and 28.22% HREO from 78 metres. The filing states historical drill hole collars are concentrated at the northern end of an approximately 6 km-long radiometric anomaly.

Planned Field Activities and Upcoming UAV Geophysical Survey

AuKing has commenced preparations for the next phase of exploration at Machinga, with field activities planned for November 2026 and a proposed UAV-based geophysical survey targeted for early December 2026, subject to contractor availability and operational approvals. The initial field program will comprise geological mapping, rock-chip and soil sampling, verification of historical exploration sites, and engagement with local stakeholders. These activities will focus on evaluating the priority areas of interest. Datasets from historical drilling, geochemistry and geophysics are being integrated to assess extensions to mineralisation along strike and at depth, and to identify new targets across the broader project area.
