Extremely high-grade copper-gold Core Zone to drive early production

Exceptional drilling results from the high-grade core zone ( Core Zone ) included 42.0m @ 6.1% Copper Equivalent 1 (CuEq) (including a Volcanogenic Massive Sulphide ( VMS ) zone of 9.8m @ 16.5% CuEq ) and 51.5m @ 4.9% CuEq (including 17.0m @ 9.1% CuEq ) These results highlight the Core Zone’s potential to underpin early, high-margin production. Given the strength of these results, FireFly will incorporate them into an updated Mineral Resource Estimate, which will then feed into the economic studies. The current Green Bay Mineral Resource Estimate ( MRE ) stands at 50.4Mt @ 2.0% CuEq in the Measured & Indicated ( M&I ) categories plus 29.3Mt @ 2.5% CuEq in Inferred. The Preliminary Economic Assessment ( PEA ) /Scoping Study, which is on track for completion in August 2026, 2 will assess development scenarios for an upscaled restart of copper-gold production at Green Bay. The latest results, generated primarily from infill drilling, are expected to be reflected in the M&I Mineral Resource categories, which is central to the economic studies. Upper VMS zones also continue to deliver high-grade copper-gold intersections, including 20.7m @ 7.7% CuEq and 13.6m @ 6.8% CuEq. Six underground rigs operated throughout the quarter (four conducting infill drilling, and two conducting step-out drilling), with underground diamond drilling at Green Bay totalling 197,714m from acquisition until 30 June 2026. Regional exploration continues, with two surface rigs testing geophysical targets near the Ming Mine and a third rig conducting maiden drilling at the Tilt Cove project. FireFly completed the sale of its Ontario Gold Assets to Bellavista Resources (ASX: BVR) ( Bellavista ), simplifying the portfolio to focus on Green Bay. FireFly was promoted to the S&P/ASX 200 Index , effective 22 June 2026, reflecting the Company’s growing market capitalisation and institutional profile. FireFly remains well-funded, with ~A$196.4 million (unaudited) in cash and liquid investments as at 30 June 2026.

FireFly Managing Director Steve Parsons said: “The outstanding results we are seeing from the high-grade Core Zone continue to exceed our expectations, both in scale and in grade, reinforcing our view that this zone can underpin early production at Green Bay. “Given the strength of these results, we have decided to incorporate them into an updated Mineral Resource Estimate ahead of our economic studies. This means the PEA/Scoping Study will now be completed in August this year. “This was also a quarter of portfolio simplification. Completing the sale of our Ontario Gold Assets to Bellavista allows FireFly to focus on Green Bay. “Promotion to the S&P/ASX 200 reflects the growing recognition of the Company among institutional investors. “Eight rigs continue to run at Green Bay, and we head into the second half of the year well-funded and with real momentum behind both the drill bit and the economic studies”.

FireFly Metals Ltd (ASX/TSX: FFM) ( FireFly or the Company ) is pleased to report on its outstanding drilling results and other key achievements during the quarter ended 30 June 2026. During the period, the Company continued its multi-rig underground drilling campaign at the Green Bay Copper-Gold Project in Newfoundland and Labrador, Canada, delivering further outstanding results that reinforce the scale and continuity of the high-grade Core Zone...
