[Ferro-Alloys.com] Ira Miri Sample Exceeds Expectations Ahead of Completion

Estrella Resources Limited (ASX: ESR) (“Estrella” or “the Company”) is pleased to advise that approximately 22,598 tonnes of high-grade manganese ore have been successfully extracted from the Ira Miri Project in Timor-Leste. This forms part of the permitted 30,000-tonne market sample, which will be sold and shipped to selected potential offtake partners for detailed assessment of the ore’s physical, chemical, and processing characteristics.

The extraction of this sample marks a major operational milestone, validating the scale, quality, and development potential of Ira Miri. Establishing this material pipeline within a short timeframe demonstrates Estrella’s commitment to a rapid development strategy, with the Company’s maiden drilling at Ira Miri commencing in late May 20253—representing an impressive nine-month progression from discovery to extraction.

Commenting on market sample, Managing Director Chris Daws said: “The accelerating extraction of high-grade, high-purity Ira Miri manganese is a major development for Estrella and its shareholders. Not only have we demonstrated the project has the scale to produce a sizable market sample, but we are also yet to fully test our deeper and adjacent targets. This is only one of several prospects across Timor-Leste, a region that remains virtually unexplored and highly prospective. Our local Timor-Leste team and contractors have delivered exceptional work, and the strong support of the Timor-Leste Government has enabled us to move efficiently. Approval of the port stockpile location allows us to progress to the next phase—delivering material into the hands of international partners eager to assess its suitability for various end-uses. We believe there is strong potential for further positive developments at Ira Miri and across our broader Timor-Leste portfolio. Go Estrella!”

Estrella’s geological team continues to refine the project’s exploration model. The pit was strategically designed to target zones containing very high-grade intercepts (e.g., 8.05m @ 53% Mn from EMDD002 and 11.97m @ 28.9% Mn from EMDD033).1,2

Importantly, Induced Polarisation (IP) surveys have highlighted large, highly chargeable anomalies beneath the current pit design—consistent with potential supergene manganese accumulations. These SE and NW deep anomalies remain untested, representing compelling targets for future drilling and potential project growth.

The anomalies have significant potential to expand current manganese extractions and represent high-priority follow-up drill targets.

The Company is pleased to advise that the Autoridade Nacional dos Minerais, I.P. (ANM) of Timor-Leste has approved the port stockpile location, which enables the site for use. Estrella will arrange the DSO to be on-loaded into a bulk carrier, avoiding lengthy road transport.

Next Steps

Estrella is reviewing logistics and preparing the Ira Miri port stockpile for Direct Shipping Ore (DSO) blending to meet customer specifications. Barging and trans-shipment into an offshore bulk carrier—a standard practice throughout the region—will be utilised to optimise efficiency.

Following strong early-stage operational success, Estrella intends to apply for a Category A Mining Licence with the ANM. This licence will enable full-scale development of the Ira Miri Manganese Project.
