• Premier1 to commence 3,700m RC drilling at the Mt Kersey Gold Prospect
• Targeting a preserved 1km+ hydrothermal system with coincident gold and multi-element soil anomalies
• High-grade rock chips up to 26.4 g/t Au highlight potential for higher grades

Premier1 Lithium is pleased to announce the imminent commencement of a 3,700m RC drilling program at the Mt Kersey Gold Prospect, one of several highly prospective gold targets within its 100%-owned Yalgoo Gold Project in Western Australia. The Mt Kersey Prospect lies within a 5 square km zone of known gold mineralization, including the Wadgingarra Prospect where Premier1 has reported a Maiden Inferred Mineral Resource of 150kt at 2.7g/t Au for 13koz contained gold. The upcoming drilling program is designed to test the Mt Kersey target, which is characterized by a preserved 1km+ hydrothermal system with coincident gold and multi-element soil anomalies (Mo-Bi-Te-W-As). High-grade rock chip samples up to 26.4 g/t Au and 14.2 g/t Au have been collected from the prospect, highlighting its potential for higher-grade mineralization. With all necessary regulatory approvals and site preparations now complete, Premier1 is poised to commence drilling at Mt Kersey in mid-February 2026. The program will be supported by up to $180,000 in co-funding from the Western Australian Government's Exploration Incentive Scheme, as well as an existing $176,000 drilling credit, significantly reducing Premier1's cash outlay.

Premier1 is fully focused on advancing its gold and copper prospects in Western Australia to deliver value for shareholders. The upcoming drilling program at the Mt Kersey Gold Prospect represents a key step in this strategy, with the potential to unlock a significant new gold discovery within the company's Yalgoo Gold Project.
