Asian Battery Metals (ASX:AZ9) confirms thick copper and gold zones at Maikhan Uul

Asian Battery Metals has provided an analytically useful set of assay results from its due diligence drilling at the Maikhan Uul copper gold volcanogenic massive sulphide project in southwestern Mongolia, with the data reinforcing earlier geological work and setting up a decisive phase of technical and legal assessment.

The company completed the drilling as part of its exclusive rights to evaluate and potentially acquire the project, which sits within the Central Asian Orogenic Belt.

The announcement outlines a detailed comparison of new and historical drilling, metallurgical context and the status of surface work, providing investors with a clearer picture of both the project’s substance and the work still required to complete due diligence.

Highlights

• High grade copper and gold assays from drillhole MU2501.

• Massive sulphide intercepts include 14.5m at 2.23% Cu and 0.73g/t Au from 132.5m.

• Shallow gold and silver zones up to 5.2m at 6.54g/t Au and 126.40g/t Ag from 36.9m.

• Twin hole confirms historical massive sulphide positions.

• Assays for MU2502 pending.

• Due diligence expected to complete in December 2025 or January 2026.

The company undertook two confirmatory drillholes, twinning the historical MU_DH1204 hole and stepping 73 metres east to test for an extension of the massive sulphide system.

MU2501 was collared approximately one metre east of the historical hole and drilled to a depth of 258.5 metres.

The hole intersected massive sulphide mineralisation from 132.5 metres, with Table 1 on page 3 showing a continuous 14.5 metre interval grading 2.23 per cent copper and 0.73 grams per tonne gold, including internal zones of 4.8 metres at 2.80 per cent copper and 6.3 metres at 2.58 per cent copper.

Further down hole, 2.6 metres at 2.28 per cent copper and 0.49 grams per tonne gold from 154.1 metres provide an additional point of correlation with the earlier work.

These zones sit well above the massive sulphide units and have prompted further surface reconnaissance to delineate lateral extent, with mapping and outcrop sampling results expected soon.

The comparison between MU2501 and the historical hole is laid out in Table 3 on page 8, highlighting the differences in grade while demonstrating consistency in the position and thickness of key mineralised intervals.

The company attributes the grade variation partly to the nuggety nature of gold and silver, an issue that prompted the use of metallic screen fire assay methods for specific intervals.

This is backed by the commentary on page 3 describing variability between initial fire assay, repeat and split assays.

The geological and structural context is also illustrated in the cross section on page 7, which shows the massive sulphide zone lying below the previously drilled resource area and indicates additional untested up dip and deeper targets.

Asian Battery Metals Managing Director Gan Ochir Zunduisuren said

“The high grade copper and gold assay results from the Maikhan Uul Cu Au drilling strongly corroborate previous geological findings. The confirmation of shallow high grade gold is an exciting development that will potentially add significant value to the project.”

With due diligence drilling complete and assays pending for MU2502, the next steps outlined on page 2 include ongoing technical work, metallurgical test work for the Oval copper nickel project and finalisation of legal and technical assessments.

Subject to the outcomes of these processes, the company may then proceed to settle the acquisition of the Maikhan Uul project.

Planning for the 2026 drilling and exploration program is already flagged, although the timing remains contingent on due diligence and completion of the current analytical work.

The latest results place Asian Battery Metals in a stronger position to determine the potential of the Maikhan Uul project, particularly in relation to the continuity of the massive sulphide zones and the significance of the shallow precious metal intervals.

The broader context outlined in the announcement, including historical work and current geophysical surveys, shows a project with considerable technical detail still to come.

The company expects results from MU2502 and surface reconnaissance in the near term, adding further clarity as it progresses toward a final acquisition decision.
