Specific pricing terms remain commercially confidential. Estrella Resources Limited (ASX: ESR) (Estrella or the Company) is pleased to announce that it has signed a binding sales agreement with private Australian company Repusource Pty Ltd (Repusource) for 27,000 tonnes of manganese ore from its Ira Miri Manganese Project in Timor-Leste. The agreement advances the existing manganese bulk sample towards shipment and customer evaluation, marking an important step in Estrella's efforts to establish a commercial market for Ira Miri and more broadly Timor-Leste manganese. Repusource supplies manganese to multiple processing customers across Asia Pacific markets. The agreement provides Estrella with an efficient pathway to introduce Ira Miri manganese to a broader customer base, leveraging Repusource's established regional supply chain network and proximity to key processing markets. The agreement follows the receipt of export authorisation announced on 28 October 2026 and completes the next commercial milestone identified in that update.1 The sale forms part of the Estrella Murak Rai (EMR) joint venture, which Estrella manages and in which it holds a 70% interest. The sale will test customer acceptance of Ira Miri material and the practical costs and requirements of delivering it to market. These results will inform potential longer-term supply discussions and the next stage of project assessment. 1 ASX announcement, 28 October 2026, “Export authorisation received for Ira Miri Manganese bulk sample”. Commenting on the agreement, Managing Director Robert Mencel said: “Signing this agreement gives us a contracted buyer for the Ira Miri bulk sample and marks another important step towards delivering the material to market. It follows export authorisation and the work undertaken with our Timorese joint venture partner to extract the parcel and prepare for shipment. “Our focus is now on completing the shipping and payment arrangements and loading the cargo. Working with Repusource provides an efficient way to introduce Ira Miri manganese to multiple processing customers across the Asia Pacific region, while leveraging established regional supply chains. “This initial sale will provide valuable feedback on customer acceptance and the practical requirements of exporting our manganese product, helping us assess future supply opportunities and the longer-term commercial potential of Ira Miri.” Key sales terms • Quantity: 27,000 metric tonnes, with a ±5% option exercisable by the buyer.

Shipment and market appraisal As reported on 28 October, causeway construction is underway at Tenu Port and manganese is being transferred from the stockpile to the loading area.¹ The next steps are to finalise the vessel and loading schedule, complete the agreed payment arrangements and undertake the required independent testing and shipment documentation. The bulk sample was extracted under the January 2026 agreement with Timor-Leste’s Autoridade Nacional dos Minerais, I.P. (ANM), which authorised extraction of up to 30,000 tonnes for market appraisal.¹ The sale will allow the material to be evaluated through customer operations and support assessment of potential future offtake opportunities. 2 ASX announcement, 13 October 2026, “Helicopter Survey Commences”, joint venture ownership disclosures. The agreement covers this bulk sample parcel and does not commit the buyer to ongoing purchases. The programme does not constitute approval for ongoing commercial mining. Future full-scale development remains subject to the required licensing and project assessment work. Contract execution does not itself represent shipment, recognised revenue or cash received. Estrella will update the market as shipment arrangements are finalised and delivery progresses. Commenting on the agreement , José Gonçalves, President of MURAK RAI TIMOR, E.P said: "We are delighted with the successful completion of this 27,000 metric tonnes manganese sale.
