- An updated Mineral Resource Estimate is planned for release later this quarter
- The current Mineral Resource Estimate for Green Bay totals 24.4Mt at 1.9% for 460Kt CuEq of Measured & Indicated Resources and 34.5Mt at 2.0% for 690Kt CuEq of Inferred Resources (see ASX announcement dated 29 October 2024)
- The infill drilling results in this announcement suggest a significant increase in higher confidence Measured and Indicated (M&I) Mineral Resource category may be expected in the upcoming Mineral Resource Estimate update; The highly valuable M&I Resource will underpin preliminary economic studies that are scheduled for completion in Q1 2026
- Assay results are due in the coming weeks for step-out drilling targeting down-plunge extensions of Ming mineralisation
- Eight diamond rigs now operating (six underground and two on surface) to upgrade the current Mineral Resource, extend known mineralisation and make new regional discoveries

PERTH, Australia, Oct. 09, 2025 (GLOBE NEWSWIRE) — FireFly Metals Ltd (ASX, TSX: FFM) (Company or FireFly) is pleased to announce further high-grade infill drilling results from its underground drilling at the Green Bay Copper-Gold Project.
Article content
An extensive six-rig underground drill campaign is underway at the Ming Mine with the dual objectives of growing the current Mineral Resource and, most importantly, upgrading more of the Inferred Resources to the comparatively more valuable Measured and Indicated (M&I) Mineral Resource categories.
Article content
Article content
Infill drilling continues to confirm the presence of strong and consistent mineralisation in areas previously subject to wide-spaced drilling. Drilling of the upper high-grade copper and gold VMS lenses has returned exceptional intersections, including 4.4m @ 19.5% CuEq, 10.1m @ 10.1% CuEq and 8.0m @ 8.6%CuEq (all approximate true thickness). Additional drilling of the broad copper stringer FWZ continues to highlight thick zones of mineralisation that are likely suitable for large-scale bulk mining. Infill intersections returned recently include world-class results such as 117m @ 2.1% CuEq, 51.9m @ 2.0% CuEq and 22.1m @ 4.9% CuEq.
Article content
The infill drilling results in this announcement suggest a significant increase in the higher confidence Measured and Indicated (M&I) Mineral Resource category may be expected in the Mineral Resource Estimate update planned for later this quarter.3

The current Mineral Resource Estimate stands at 24.4Mt @ 1.9% for 460Kt CuEq of M&I Resources and a further 34.5Mt @ 2.0% for 690Kt CuEq
of Inferred Resources.4

_______________
1 Metal equivalent for drill results reported in this announcement have been calculated at a copper price of US$8,750/t, gold price of US$2,500/oz, silver price of US$25/oz and zinc price of US$2,500/t. Metallurgical recoveries have been set at 95% for copper, 85% for precious metals and 50% for zinc. CuEq(%) = Cu(%) + (Au(g/t) x 0.82190) + (Ag(g/t) x 0.00822) + (Zn(%) x 0.15038). In the opinion of the Company, all elements included in the metal equivalent calculation have a reasonable potential to be sold and recovered based on current market conditions, metallurgical test work, and historical performance achieved at the Green Bay project whilst in operation.

Article content
The higher-confidence M&I categories of Mineral Resources are important because they will underpin the economic studies into upscaled production at Green Bay that the Company plans to complete in H1 2026.
Article content
Regionally, exploration programmes are also well underway, following the North American summer break period, with two diamond drill rigs now on site and ready to accelerate the regional discovery campaign. Geophysical data collection continues, with a detailed helimagnetic survey being conducted over the central Green Bay leases. A comprehensive VTEM survey is being completed over the entire 115km2 of the adjacent Tilt Cove Project to the east of the Ming Mine. The new geophysical data is expected to be available in the coming weeks. The rigs will systematically test geophysical anomalies generated by this new data and the Company’s previous airborne VTEM surveys.

About the Drilling Results
Article content
Drilling at the Ming underground copper-gold mine recommenced following the acquisition of the Green Bay Copper-Gold Project by FireFly in October 2023. In total, FireFly has completed 241 underground holes for a total of ~123,673m of underground diamond drilling to 6 October 2025.
Article content
This announcement contains the results of 49 drill holes. The drilling results reported in this announcement are predominantly the results of infill drilling and drilling of holes targeting the lateral margins of the mineralisation. Logging and analysis of additional drill holes is ongoing, and further details will be reported as results are received. In addition, step-out growth drilling is underway with the results due in the coming weeks.
Article content
There are two distinct styles of mineralisation present at the Green Bay Ming Mine, consisting of a series of upper copper-gold rich VMS lenses underlain by a broad copper-rich stringer zone, known as the Footwall Zone (or FWZ).
Article content
Article content
The Footwall Zone is extensive, with the copper stringer mineralisation observed over thicknesses of ~150m and widths exceeding 200m. The known strike of the mineralisation defined to date is 2.3km and it remains open down-plunge.
Article content
Six drill rigs are currently operating underground, with the focus split between both step-out extension and exploration (two rigs) and infill Resource conversion drilling (four rigs).
Article content
The location of drill positions and holes reported in this announcement is presented in Figure 2. Significant assay results are presented in Appendix B of this announcement.

820L Resource Conversion Drilling
Article content
Resource definition drilling from the 820L Access was planned to infill the lower FWZ between 800mRL and 1,000mRL. This drilling was undertaken beneath the upper VMS mineralisation, thus no intersections of VMS style mineralisation were returned. All drilling returned multiple zones of broad FWZ style mineralisation and all mineralisation is ~ true thickness. Key intersections include, but are not limited to:
