• Application for early renewal of Simberi Mining Lease to be considered by Mining Advisory Council in June 2025
• Extensive discussions with stakeholders on renewal application and enhanced royalty proposal
• Renewal key step to unlock Sulphide Ore Reserves and expand gold production

St Barbara Limited (ASX: SBM) has announced that it has been informed by the Managing Director of the Mineral Resources Authority of Papua New Guinea (MRA) that the Mining Advisory Council (MAC) will be considering the application for the early renewal of the Simberi Mining Lease (ML) at its June 2025 monthly meeting. The meeting, planned for the last week of June, is the final step before a recommendation is made to the Mining Minister for the renewal. The ML Warden Court hearing took place at Simberi Island on 8 April 2025 and was well supported with a large turnout of community members. The hearing followed the MRA's acceptance and registration of Simberi's application for early renewal of the Simberi ML, announced in December 2024. The Company understands that all questions, arising from the MRA's review of the technical materials supporting the application, are now answered and the materials are ready for this next MAC meeting. St Barbara carried out extensive discussions with stakeholders regarding the submission of the early renewal application for the Simberi ML and in relation to the Company's proposal for an enhanced net profits-based royalty under a new Simberi Memorandum of Agreement. The renewal of the Simberi Mining Lease is a key step towards unlocking the Sulphide Ore Reserves at Simberi and expanding gold production to over 200,000 ounces per annum.
