Premier1 Lithium (ASX:PLC) has expanded a gold-in-soil anomaly at the Rochefort prospect within the Abbotts North Project, located 35km north of Meekatharra in the Murchison region of Western Australia.
The anomaly extends over an area of 350m by 350m, remaining open to the south and peaking up to 30 parts per billion gold from reprocessing of regional and historical airborne magnetic data.
Exploration Manager Paul Smith says the results returned show potential for the anomaly to continue beneath colluvial and transported cover.
“We plan 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,” Smith says.
“Reprocessing of historical airborne magnetic datasets has highlighted a broader zone of quartz dolerite, which is largely under cover to the north and east of the gold anomaly.
“An interpretation of airborne magnetic data suggests that the dolerites have intruded into folded ultramafic rocks which increases the prospectivity of the Rochefort prospect.”
Premier1 describes Rochefort as a “compelling target” due to its footprint, potential, proven host geology, structure, and proximity to production.
Rochefort is located 20km north of New Murchison Gold’s (ASX:NMG) Crown Prince deposit, which hosts a resource of 2.2 million tonnes @ 3.9 grams per tonne gold.
Crown Prince is now in production, with its first ore shipments being directed to Westgold Resources’ (ASX:WGX) Bluebird processing facility.
Premier1 Lithium is a Western Australian explorer focused on developing gold, copper, and lithium projects within greenstone belts.
