Copper-gold Core Zone targets early production

Exceptional intersections in the Core Zone will be included in the imminent resource update and PEA/Scoping Study; FireFly joins the S&P/ASX 200 Index HIGHLIGHTS 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 ) (see ASX announcement dated 2 July 2026) These results highlight the Core Zone’s potential to underpin early, high-margin production (see ASX announcement dated 2 July 2026) 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 (see ASX announcement dated 2 July 2026) 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 R
