• Outstanding drilling results continue to demonstrate strong continuity of mineralisation at Green Bay, particularly in the high-grade Core Zone and adjacent Volcanogenic Massive Sulphide (VMS) zones
• Latest holes into the +800m zone of thick high-grade copper and gold mineralisation (Core Zone), returned intersections of 70.8m @ 4.0% copper equivalent (CuEq) and 53.3m @ 4.1% CuEq
• The high-grade Core Zone has the potential to be an extremely valuable feed source in the early years of future production scenarios

Firefly Metals Ltd has announced more exceptional drilling results that demonstrate strong continuity in the high-grade mineralisation at the Green Bay Copper-Gold Project in Newfoundland and Labrador, Canada. Infill drilling of the high-grade Core Zone continues to yield thick high-grade zones of copper and gold where the upper VMS mineralisation converges with the broad stringer zone in the footwall. Latest results include 70.8m @ 4.0% CuEq and 53.3m @ 4.1% CuEq, confirming the continuity of the Core Zone, which has a current Mineral Resource of 8.8Mt @ 3.9% CuEq M&I and 10.9Mt @ 3.8% CuEq Inferred. The Core Zone has potential to grow and remains open with the deepest hole drilled to date returning an intersection of 49.1m @ 6.1% CuEq. The total Mineral Resource Estimate (MRE) for the Green Bay project stands at 50.4Mt @ 2.0% CuEq M&I and 29.3Mt @ 2.5% CuEq Inferred. The Core Zone will form an important part of the potential upscaled mine restart currently being evaluated in economic studies, with early mining expected to focus on this high-grade copper and gold zone. Recent drilling has also defined and extended the mineralisation in the upper copper and gold-rich VMS zones, with intersections of 11.9m @ 8.1% CuEq, 25.7m @ 7.8% CuEq and 16.3m @ 7.7% CuEq. Drilling into the broad FW stringer zone has also returned strong results including 20.9m @ 4.5% CuEq. The economic studies on the upscaled resumption of copper and gold production at Green Bay are well underway with delivery of the Preliminary Economic Assessment (PEA) / Scoping Study anticipated in mid-2026.

Drilling continues underground with six rigs focused on a combination of both infill drilling and extending the known Mineral Resource in the high-grade VMS zones. Regional exploration is starting to accelerate following the winter period with drilling at the Company's Tilt Cove project expected to commence in the coming months.
