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 0.0822) + (Zn(%) x 0.15038). In the opinion of the Company, all elements included in the metal equivalent calculation have a reasonable potential to be recovered and sold based on current market conditions, metallurgical test work, and historical performance achieved at the Green Bay project whilst in operation.
| FireFly Managing Director Steve Parsons said: “If grade is king, we are on track for an almighty coronation at Green Bay, with a resource update and economic studies almost finished. “These high-grade infill drilling results, such as 11.5m at 11.1% copper, will feed straight into the resource update and support our strategy to grow the all-important Measured & Indicated category. “This will in turn drive the economic studies, where the impact of the high-grade core zone is expected to be seen in the early years of a production re-start. “As we put the finishing touches on the resource update and economic studies, we are continuing our drilling blitz, with six rigs underground and regional targets being tested”. | ||
PERTH, Australia, Aug. 03, 2026 (GLOBE NEWSWIRE) -- FireFly Metals Ltd (ASX, TSX: FFM) is pleased to announce more exceptional drilling results that demonstrate the strong continuity and high-grade nature of mineralisation at the Green Bay Copper-Gold Project in Newfoundland and Labrador, Canada.
The six-rig underground drilling program continued to focus on increasing data density in the higher-grade VMS and Core Zones of the deposit. These results will be incorporated into the imminent MRE update which will underpin the concurrent economic studies.
The Preliminary Economic Assessment (PEA) remains on track for completion by the end of August 2026. This study will highlight multiple potential development scenarios for the future operation at Green Bay.
The current MRE for the Green Bay project stands at 50.4Mt @ 2.0% CuEq M&I and 29.3Mt @ 2.5% CuEq Inferred (see ASX announcement dated 18 November 2025).
Significantly, infill drilling completed since the 18 November 2025 MRE (November 2025 MRE) is expected to convert much of the Mineral Resource into the higher-confidence M&I categories, allowing for the upcoming economic study to incorporate at least 70% M&I in the mine plan, and also paving the way for the declaration of a maiden Ore Reserve before the end of 2026.
Drilling of the VMS lodes has confirmed the presence of strong copper and gold mineralisation to the west and down-plunge of existing mine development. This is significant because the strike width of the sulphide horizons now extends beyond 400m in places and significantly enhances the copper tonnes per vertical metre in the deposit. Recent intersections include 11.5m @ 13.2% CuEq, 13.5m @ 11.1% CuEq and 18.9m @ 8.2% CuEq.
Infill drilling of the high-grade convergent Core Zone continues to return exceptional copper and gold intersections over considerable thicknesses. Latest results from the Core Zone included 65.3m @ 4.3% CuEq, further demonstrating continuity of what is shaping up as an economically significant part of future mining plans being considered in the upcoming economic studies. The Core Zone has a current Mineral Resource of 8.8Mt @ 3.9% CuEq M&I and 10.9Mt @ 3.8% CuEq Inferred with significant potential to grow (see ASX announcement dated 18 November 2025). The deepest hole drilled to date returned an intersection of 49.0m @ 6.1% CuEq (see ASX announcement dated 16 October 2025).
Select holes were extended to test mineralisation in the lower FWZ that hosts copper stringer-style mineralisation. Results returned included thick high-grade zones of 36.9m @ 2.7% CuEq.
Regional exploration is starting to accelerate following the winter period. Until recently, work has focused on target generation utilising geophysics, prospecting and historic data compilation. Three surface rigs are currently testing geophysical anomalies at Green Bay. Maiden drilling at the Company’s Tilt Cove project has commenced with results pending.
FireFly is well funded to continue its growth drilling, economic studies and pre-construction early works activities. The Company has ~A$196.4M in cash and liquid investments (unaudited) as at 30 June 2026.

About the Drilling Results
Drilling at the Ming underground copper-gold mine recommenced following FireFly’s acquisition of the Green Bay Copper-Gold Project in October 2023. In total, FireFly has completed 197,714m of underground diamond drilling up to 30 June 2026.
This announcement contains the results of 42 completed drill holes. The drilling results focus on infill drilling and holes targeting the lateral margins of the mineralisation. Logging and analysis of additional drill holes is ongoing.
There are two distinct styles of mineralisation present at the Ming Mine, consisting of a series of upper copper-gold rich VMS lenses underlain by the broad copper-rich stringer FWZ. This release contains final holes to be included in the MRE update that is currently underway.
The FWZ 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 three kilometres and it remains open down-plunge.
The high-grade Core Zone exists where the VMS converges with the upper FWZ mineralisation down-plunge. The Core Zone has a current Mineral Resource of 8.8Mt @ 3.9% CuEq M&I and 10.9Mt @ 3.8% CuEq Inferred.
Six drill rigs are currently operating underground, with the focus split between both lateral step-out extension (two rigs) and infill Mineral Resource conversion drilling (four rigs).
The majority of drilling reported in this announcement has been conducted from the 805L drill drive with several holes drilled from the 685L and 790L. Whilst this development is currently being utilised for exploration, it will form an important part of future mine infrastructure for the potential upscaled operation.
Additional development has been completed from this drive to position the rigs to test for high-grade extensions of the 1806 and 1807 VMS lodes. The location of drill platforms and holes reported in this announcement are presented in Figure 2. Significant assay results are presented in Appendix B of this announcement.

Resource Conversion Drilling
805L Exploration Drive Crosscut 3 West
The drilling reported from the mid-section of the 805L Exploration drive (Crosscut 3 West) focused on upgrading the data density of the Inferred Mineral Resource reported in the November 2025 MRE.
Recent drilling focused on testing the western peripheral margins of the high-grade VMS zones which will potentially form an important high-grade component in the early years of an upscaled restart of production at the Ming Mine. The zones at the margins of the VMS lenses are typically gold-rich which is likely the result of lateral variations in both fluid composition and fluid depositional temperature.
Results from the 805L Crosscut 3 are summarised in Table 1.

2026 Forward Work Plans
The FireFly growth strategy remains focused on advancing the Green Bay project towards the resumption of upscaled copper and gold production. Near term activities remain focused on:
Green Bay (Ming Mine) Mineral Resource Development
As of 30 June 2026, the Company had completed 197,714 metres of underground diamond drilling. Six underground rigs will continue to advance the underground Mineral Resource conversion and extension activities for the foreseeable future.
Near-term underground drilling will remain focused on infill definition to upgrade areas of Inferred to the higher confidence M&I Mineral Resource categories ahead of further economic studies into resuming upscaled production at Green Bay. The decision to focus on infill drilling is driven by numerous factors, including:
The Company intends to complete sufficient economic work to declare a maiden Ore Reserve by the end of 2026.
Green Bay (Ming Mine) Mineral Resource Growth
Mineral Resource growth in coming months will be driven by testing down plunge extensions of the high-grade VMS channels parallel to the Ming North lode. Drilling in this announcement shows the 1806 VMS continues at depth and Mineral Resource additions are expected from this zone.
The planned MRE update will incorporate drilling completed since the issue of the previous estimate in November 2025 and will underpin the first economic studies.
Economic Studies
Economic and technical studies on the upscaled resumption of copper and gold production at Green Bay are nearing completion.
The study, on track for completion before the end of August 2026, will meet the criteria of a Scoping Study, in the 2012 Edition of the Australasian Code for Reporting of Exploration Results, Mineral Resources and Ore Reserves (JORC Code 2012), and Preliminary Economic Assessment, in Canadian National Instrument NI 43-101 – Standards of Disclosure for Mineral Projects (NI 43-101).
The study will consider various development scenarios for the project, including several haulage scenarios (e.g., shaft, decline), annual production rates (scale), and life of mine metal production.
Upon completion of the PEA, focus will shift to completion of a Feasibility Study, expected to be completed in Q1 2027.
Project Development
The Company has secured conditional release from further Environmental Assessment by the Province of Newfoundland and Labrador for a start-up mining and processing operation (see ASX announcement dated 5 August 2025). FireFly has now satisfied conditions of the release required to commence early works activities and has commenced applying for construction permits. The Company has commenced selective low-cost seasonal early works to prepare the Project for future development and construction.
Regional & Generative Exploration
Regional exploration is accelerating following a scheduled winter hiatus. Recent activity has focused on target generation incorporating geophysics survey and interpretation, prospecting programs and compilation of historic datasets. Two surface diamond drill rigs are currently testing geophysical anomalies in the areas south of the Ming Mine. A third surface rig has commenced drilling at the Company’s Tilt Cove project.
Balance Sheet and Funding Position
FireFly is well-funded to execute its growth drilling program, economic studies and pre-construction early works activities. As at 30 June 2026, the Company has approximately A$196.4 million in cash and liquid investments on an unaudited basis.

Mineral Resource Estimate – Little Deer
The Mineral Resource Estimate for Little Deer referred to in this announcement was first reported in the Company’s ASX announcement dated 29 October 2024, titled ‘Resource Increases 42% to 1.2Mt of contained metal at 2% Copper Eq’ and is also set out in the Technical Report for the Little Deer Copper Project, titled ‘Technical Report and Updated Mineral Resource Estimate of the Little Deer Complex Copper Deposits, Newfoundland, Canada’ with an effective date of 26 June 2024, available on SEDAR+ at www.sedarplus.ca.
Metal equivalents
Metal equivalents for the Mineral Resource Estimates and Exploration Results 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. Individual Mineral Resource grades for the metals are set out in Appendix A of this announcement. Individual grades for the metals for the reporting of metal equivalents for Exploration Results are set out in the ASX announcements in which the Exploration Results were first reported by the Company.
Copper equivalents for the Mineral Resource Estimates do not include zinc and were calculated based on the formula:
CuEq(%) = Cu(%) + (Au(g/t) x 0.82190) + (Ag(g/t) x 0.00822).
Copper equivalents for the Exploration Results include zinc and were calculated based on the formula:
CuEq(%) = Cu(%) + (Au(g/t) x 0.82190) + (Ag(g/t) x 0.00822) + (Zn(%) x 0.15038)
Metallurgical factors have been applied to the metal equivalent calculation. Copper recovery used was 95%. Historical production at the Ming Mine has a documented copper recovery of ~96%. Precious metal (gold and silver) metallurgical recovery was assumed at 85% on the basis of historical recoveries achieved at the Ming Mine in addition to historical metallurgical test work to increase precious metal recoveries.
In the opinion of the Company, all elements included in the metal equivalent calculation have a reasonable potential to be recovered and sold based on current market conditions, metallurgical test work, the Company’s operational experience and, where relevant, historical performance achieved at the Green Bay project whilst in operation.

APPENDIX B – Significant Intersection Table
Collar co-ordinates and orientation are listed in the local Ming Mine grid, which is rotated +35 degrees from NAD83 True North. Significant intersections reported are those above a 1% copper cut-off or 0.5g/t gold, and contain a maximum of 6 metres of internal waste. Please refer to the compliance statements for further details on parameters used in the copper equivalent calculation. All results are approximate true width (~TW) unless otherwise noted.
