AuKing Mining Limited has extended the second diamond drill hole at the Tundulu Rare Earth Project in southern Malawi to a final depth of 400.42 metres after continuous geological logging identified extensive carbonatite lithology beyond initial depth targets.

The second hole, designated 26NH023, was originally planned to reach a depth of 300 metres by adding a diamond tail to an existing reverse circulation hole. However, fieldwork was prolonged as carbonatite intersections continued past the planned boundary. End-of-hole logging confirmed that the carbonatite geology remains open at depth, providing further confidence in the emerging geological interpretation.

This follows a similar extension on the program's first diamond hole, 26NH032, which was originally slated for 300 metres before being extended to a final depth of 510.6 metres. Prior to launching the diamond phase, AuKing completed the initial reverse circulation drilling program on 31 July 2026, comprising 4,300 metres drilled across 31 holes.

The widespread carbonatite intervals identified across both deep diamond holes have strengthened confidence that the overall geological model around Nathace Hill is substantially broader and deeper than initially anticipated. Field teams have decided to conclude drilling on both deep holes and progress the rig to other target areas across the project site to continue building the broader geological dataset.

AuKing is structuring its ongoing exploration program to support a potential maiden Mineral Resource Estimate for the Tundulu Project later in 2026. Assay results for samples dispatched from the drilling program are currently pending laboratory analysis.
