First Atlantic Nickel Expands RPM Zone to 750 Meters in Width with Second Phase 2 Drill Hole: AN-25-07 Intersects 495 Meters of Visible Awaruite Mineralization

GRAND FALLS-WINDSOR, Newfoundland and Labrador, Sept. 10, 2025 (GLOBE NEWSWIRE) -- First Atlantic Nickel Corp. (TSXV: FAN) (OTCQB: FANCF) (FSE: P21) ("First Atlantic" or the "Company") is pleased to report a significant expansion of visible awaruite nickel-alloy mineralization at the RPM Zone, part of its 100% owned, district-scale, 30 kilometer-long Atlantic Nickel Project in Newfoundland (the "Atlantic Nickel Project" or the "Project"). RPM Drill hole AN-25-07, the second hole of the Phase 2 program, intersected 495 meters of visibly disseminated awaruite and has expanded the mineralized section located 400 meters north of the RPM discovery holes up to 750 meters in width. This represents a ~50% increase from the 500-meter width established in Phase 1, confirming the robust lateral extent of awaruite mineralization at RPM. With holes AN-25-08 and AN-25-09 now completed on Line S3, Phase 2 drilling has tested 800 meters of north-south strike length and continues to demonstrate the scale potential of the RPM Zone as the Company advances toward defining over 1 kilometer of continuous awaruite mineralization. Concurrent with drilling, Phase 2 prospecting across the 30-kilometer Pipestone Ophiolite Complex has collected numerous surface rock samples containing visible awaruite for assay and davis tube metallurgical testing. Additional updates on the Phase 2 program are anticipated within the coming weeks.
