This is expected to be the commencement of regular fortnightly revenues from gold production with the next scheduled for 15 October and fortnightly thereafter. The Company is steadily building the gold densities of the carbon within its tanks. This gold is from the processing of gold bearing material sourced from our 100% owned Mt Boppy gold project. Based on the current feed grade of the Mt Boppy material through the plant (~1g/t Au) and current gold recoveries approximately 75%, the Company expects fortnightly revenue streams from gold ore processing to the end of 2026 within the range of A$3.0 - A$4.0m2 per fortnight. Updated forecasts will be provided when the silver circuit is commissioned. This gold sale represents an important milestone in the restart of the Wonawinta processing facility, with Manuka having progressed from recommencement of gold processing on 22 August, through to the generation of cash revenue from gold production to early 2027. Gold production represents the first stage of Manuka’s broader production strategy at Wonawinta. 1 ASX Release 30 May 2025 2 Basis A$6,000/oz Au Page | 2 Manuka Resources Limited - Level 4 Grafton Bond Building, 201 Kent St Sydney NSW Australia 2000 ABN 80 611 963 225 Tel 02 7253 2020 www.manukaresources.com.au The Company is continuing preparations for installation and commissioning of the new silver processing circuits, ahead of the planned transition to combined gold and silver production. Dennis Karp, Executive Chairman, commented: “Manuka is building a long-life precious metals production business in the Cobar Basin, centred on our Wonawinta processing facility and our 100% owned various sources of gold and silver mill feed. This first gold sale is an important step in delivering on that strategy. We have now moved from restarting the metallurgical plant to producing gold, generating revenue and establishing recurring cash inflows from the operation. Our focus now is on continuing to ramp up gold production while progressing the silver circuit, which will enable Wonawinta to fully transition to combined gold and silver production. This is where we see the real scale of the opportunity emerging.” This announcement has been approved for release by the Board of Directors of Manuka Resources Limited For further information contact: Dennis Karp Executive Chairman Manuka Resources Limited Tel. 02 7253 2020 admin@manukaresources.com.au Compliance Statements The information in this announcement that relates to previously reported Exploration Results, Exploration Targets, Mineral Resources, Ore Reserves, Production Targets and Financial Forecasts is extracted from the Company’s ASX announcements and are available to view on the Company’s website.
