Phase 3 Drilling Advances Understanding of Oval Mineralisation
Asian Battery Metals PLC (ASX:AZ9) has reported significant progress in its Phase 3 diamond drilling campaign at the Oval Cu-Ni-PGE discovery in Mongolia. The program, aimed at testing high-priority geophysical targets and expanding the known mineralised footprint, has confirmed multiple high-grade sulphide zones and intersected a possible feeder dyke that may connect to a deeper mineralised magma chamber.
The discovery of this feeder dyke, identified in drillhole OVD032 at depths between 293.7m and 295.2m, represents a potential game-changer in understanding the magmatic conduit system feeding the Oval mineralisation. This zone includes semi-massive sulphide mineralisation, suggesting a direct pathway for mineralising fluids from deeper sources.
Robust Mineralisation and Geophysical Insights
Drillhole OVD033 intercepted a substantial 28.7m interval of high-grade, net-textured sulphide mineralisation, consistent with previous high-grade intercepts at Oval. Meanwhile, OVD034 confirmed a continuation of massive sulphide mineralisation intersected in earlier drilling, with 1.3m of massive sulphide containing significant chalcopyrite and pyrrhotite percentages.
Complementing the drilling, downhole electromagnetic (DHEM) surveys have identified new conductive plates at depth, refining target zones for subsequent drilling phases. These geophysical results support the hypothesis of an extensive magmatic system with multiple mineralised intrusions beneath the Oval prospect.
Regional Exploration and Next Steps
Beyond the immediate Oval area, regional drilling is underway to test step-out targets within the broader Yambat Project. The company plans to integrate deeper penetrating geophysical methods, including a ground-based SAMSON FLEM survey, to better delineate feeder zones and mineralised intrusions at depth.
Assay results from the Phase 3 drilling are anticipated from late May 2025, which will provide critical data to validate visual mineralisation estimates and guide future exploration strategies. Asian Battery Metals’ Managing Director, Gan-Ochir Zunduisuren, emphasised the importance of these findings in confirming the potential scale of the Yambat Project and its role in supplying battery metals essential for Asia’s energy transition.
Bottom Line?
As assay results loom, Asian Battery Metals’ deep feeder dyke discovery could redefine the scale of the Oval deposit and its strategic value.
Questions in the middle?
- Will assay results confirm the high-grade visual mineralisation estimates?
- How extensive is the deeper magmatic system feeding the Oval mineralisation?
- What impact will regional drilling have on the overall resource potential of the Yambat Project?
