• Regulatory approvals and heritage clearances secured for maiden RC drilling program
• Drilling designed to test a well-defined gold target with high-grade rock chips and coherent soil anomaly
• Rochefort located ~20 km north of the producing Crown Prince deposit

Premier1 Lithium Limited (ASX:PLC) is pleased to advise its maiden Reverse Circulation (RC) drilling program at the Rochefort Gold Prospect ('Rochefort'), within the Abbotts North Project ('Abbotts North'), is set to commence in late May 2026. Rochefort features a coherent, expansive gold-in-soil anomaly measuring ~400m x 350m with strong extension potential under cover, high-grade rock chip assays of up to 11.7g/t Au, and is hosted in highly fractionated and altered quartz dolerites consistent with major Yilgarn gold systems. The prospect sits in a structurally complex zone at the juncture of several north-south trending structures and a large arcuate structure/geological contact trending north-west, with mineralisation remaining open along strike and under shallow cover. The maiden drill program will comprise up to 5 x RC holes for a total of ~1,000 metres, targeting the core of the gold anomaly and stepping out to assess the extent and continuity of the mineralised system. Rochefort is strategically located just ~20 km north of the Crown Prince deposit within the same underexplored Abbotts Greenstone Belt, which has seen minimal modern exploration despite hosting high-grade historical gold production.

The maiden drilling program at the Rochefort Gold Prospect represents an exciting step in testing this compelling, underexplored discovery opportunity within the proven Abbotts Greenstone Belt.
