• Maiden Mineral Resource Estimate at Wadgingarra: 150kt at 2.7g/t Au for 13koz gold
• Non-binding LOI signed with Mineral Mining Services to fund and manage Wadgingarra development
• High-grade gold assays confirmed at the newly identified Rochefort Prospect

During the September quarter, Premier1 Lithium advanced both development and exploration activities across its portfolio. At Yalgoo, the Company reported its maiden Mineral Resource estimate at Wadgingarra of 150kt at 2.7g/t Au for 13koz and entered into a non-binding development partnership with Mineral Mining Services Pty Ltd (MMS). At Abbotts North, follow-up sampling confirmed high-grade gold at the newly identified Rochefort Prospect and delivered further high-grade rock chip results in the north of the project. The Mineral Resource at Wadgingarra represents Premier1's first commercial opportunity, with its shallow nature and proximity to processing facilities providing low-capex development pathways. The partnership with MMS will see them fund and manage all development and commercialisation activities, while Premier1 retains ownership of the tenements and a profit share. At Abbotts North, the Rochefort Prospect has been established as a new gold discovery, with mapping defining a 40m by 40m mineralised footprint that remains open to the south. Subsequent soil sampling has outlined a 500m by 300m gold-in-soil anomaly, supporting the potential for a significant mineralised system.

Premier1 enters the next quarter with a clear focus on advancing its priority gold projects. At Yalgoo, first-pass exploration drilling is planned at the Mt Kersey target followed by resource growth drilling at Wadgingarra. At Abbotts North, preparations are underway for maiden drilling at Rochefort and follow-up of additional gold-in-soil anomalies. Geophysical surveys and heritage programs are also scheduled to refine targets and facilitate exploration.
