AuKing completed an airborne magnetics and LiDAR survey across the Tundulu region in late April 2026 The survey materially advances the Company’s understanding of Tundulu from a historically surface-focused rare earth occurrence into a geophysically constrained carbonatite system containing multiple large-scale drill-ready targets. The results reinforce the Company’s view that the known Nathace Hill mineralisation may represent only a portion of a substantially larger rare earth system. The gold dashed line outlines the interpreted Nathace Hill core of the broader Tundulu carbonatite system and includes the historical drill holes, while the white dashed line outlines areas beneath post-mineralisation sedimentary cover that remains largely unexplored. LiDAR = Light Detection and Ranging - a remote sensing technology that uses laser light pulses to measure distances and create highly detailed 3D maps or models of the Earth's surface, objects, or environments.

AuKing has commenced its planned 10,000m RC/diamond drilling program at Tundulu Well-known southern African drilling contractor, Thompson Resources has been engaged to undertake a planned 10,000m program of combined reverse circulation (RC) and diamond drilling at Tundulu across approximately 50 drill hole targets. The Thompson Resources RC rig has been mobilised to site and drilling has commenced, with a diamond rig expected to be mobilised later in June The drilling program has been designed to test extensions, structural controls, and depth continuity of rare earth element (REE) mineralisation across the Tundulu Project.

Because we’re not looking at small, discrete occurrences -The depth and consistency of the historical drilling demonstrates just how untested this system really is, and that those geochemical anomalies are actually quite indicative of something much larger.
