• Infill soil sampling has significantly expanded the Rochefort gold-in-soil anomaly
• Rochefort gold anomaly now extends over an area of 350 m x 350 m and remains open to the south, with peak values up to 30 ppb
• Reprocessing of regional and historical airborne magnetic data has revealed a significantly larger corridor of interpreted quartz dolerite, substantially increasing the prospective footprint

Premier1 Lithium Ltd (ASX:PLC) is pleased to announce that infill soil sampling assays have significantly increased the Rochefort Prospect's gold anomaly at its Abbotts North Project, located 35km north of Meekatharra in the highly prospective Murchison Region of Western Australia. The Rochefort anomaly now measures 350m by 350m, and remains open to the south, where it trends into shallow colluvial and transported cover. These results build on prior high-grade rock chip assays of up to 11.7 g/t Au as well as the identification of highly prospective quartz dolerite host rocks, and position Rochefort as a priority drill target, just 20km from the 279koz Crown Prince deposit owned by New Murchison Gold Ltd. Re-processing of regional and historical airborne magnetic data has also delivered a major upgrade to the Rochefort target, revealing a significantly larger corridor of interpreted quartz dolerite extending under cover to the north, east and south-east of the current anomaly, substantially increasing the prospective footprint. The Rochefort dolerites have been intruded into tightly folded ultramafic lithologies, creating a favourable setting for mineralising fluids to concentrate gold. Premier1 plans to return to the field in January with a larger Ultrafine™ soil program to track this anomaly under cover and refine priority drill targets for testing in the first half of 2026.
