Estrella Resources Limited has defined multiple high-conductivity targets at the Ira Miri Manganese Project in Timor-Leste following a Mobile MTd UAV passive electromagnetic geophysical survey.

The survey covered the existing Ira Miri pit area within a 3.5km by 4.2km corridor and extended over a portion of the Laleno Dome. Processing revealed multiple conductivity anomalies, including strong zones presenting as vertical "plumes" extending upwards from depth. These deep-seated features show a spatial relationship with the Laleno Dome and may represent hydrothermal-fluid pathways that deposited sulphide mineralisation.

In addition to the deep conductive plumes, the survey identified shallow-dipping anomalies that may represent manganese-bearing beds within the Noni Formation. Best anomalies will be tested by three drill-holes.

Estrella has designed an initial ~3,000-metre reverse circulation and diamond tail drilling campaign to test three compelling targets. These holes will represent the deepest mineral-exploration drilling completed to date in Timor-Leste. Drilling is scheduled to commence in September 2026.

"The results of the Mobile MTd survey have provided Estrella with a compelling new set of drill targets at Ira Miri. The identification of strong conductivity anomalies extending from depth towards surface, particularly where they coincide with the Laleno Dome, provides an important new exploration vector for the Company. While the conductivity anomalies are not, by themselves, proof of mineralisation, their geometry and geological setting provide a strong basis for drill testing. We are particularly encouraged by the scale and continuity of several of these anomalies and are excited by opportunity to test them with our first deep drilling program in this part of Timor-Leste."

Separately, Estrella plans to conduct a ~4,000-metre reverse circulation and diamond drilling campaign in the Sagadate region to augment the Werumata Limestone Deposit.
