PERTH, Australia, Oct. 29, 2025 (GLOBE NEWSWIRE) -- FireFly Metals Ltd (ASX/TSX: FFM) (FireFly or the Company) is pleased to report on a highly productive quarter which saw the Company generate more outstanding drilling results ahead of its next Mineral Resource Estimate update and progress its studies on an upscaled production restart at Green Bay.

HIGH-GRADE INFILL DRILLING
During the quarter, FireFly announced outstanding assays from infill drilling which continue to show why Green Bay is a world-class copper-gold project with very high grades, continuous mineralisation, scale potential and existing infrastructure in a tier-one location.

Figure 1: Long section through the Green Bay Ming underground mine showing the location of select drill results from ASX announcement dated 17 July 2025. Results from both the high-grade copper-gold VMS zone and broad copper Footwall Zone are shown.  The green shape is a modelled DHEM anomaly (from hole MUG25-040 - see ASX announcement dated 7 May 2025 for further details). Drill assays >0.5% copper are shown in red.

The current Mineral Resource Estimate at the Green-Bay Copper-Gold Project 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 (see ASX announcement dated 29 October 2024).

An extensive six-rig underground drill campaign is underway with the dual objectives of growing the current Mineral Resource (four rigs) and upgrading more of the Inferred Resources to the higher-confidence Measured and Indicated (M&I) categories (2 rigs).

The upcoming Mineral Resource Estimate (MRE) update, due later this year, will underpin upscaled mining and economic studies currently underway and scheduled for completion in early CY2026.

About the Drill Results

FireFly acquired the Green Bay Copper-Gold Project in October 2023 and began an extensive underground drilling campaign at Ming Mine. Since this time, the Company has completed approximately 123,064m of diamond core drilling to 30 September 2025. The diamond drilling is part of the extensive underground development program for the planned upscaling of the past-producing Ming Mine.

There are two distinct styles of mineralisation present at the Green Bay Ming Mine, consisting of a series of upper copper-gold rich Volcanogenic Massive Sulphide (VMS) lenses underlain by a broad copper stringer zone, known as the Footwall Zone (FWZ).

The Footwall Zone is extensive, with the 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 (see ASX announcement dated 16 October 2025).

Drilling continues to demonstrate continuity of the high-grade copper-gold rich VMS mineralisation, with key intersections including 11.6m @ 9.3% CuEq, 14.6m @ 6.7% CuEq, 14.9m @ 5.5% CuEq and 5.5m @ 7.1% CuEq (~true widths) (see ASX announcement dated 17 July 2025).

Infill drilling of the broader copper-rich footwall stringer zone repeatedly intersected thick and continuous mineralisation exceeding 2% copper. Highlights include 26.2m @ 5.3% CuEq, 24.1m @ 3.7% CuEq and 9.5m @ 6.4% CuEq (~ true widths) - supporting the possibility of bulk‐scale mining from the footwall domain (see ASX announcement dated 17 July 2025).

The development of phase two of the 805L exploration drive has now been completed. Two drill rigs have been mobilised to the northern extent of the platform and are testing mineralisation up to 650m beyond the current MRE.   Subsequent to the quarter, on 16 October 2025, it was announced that results of such drilling extended the known mineralisation by 430m beyond previous drilling and more than 650m beyond the current MRE.

Figure 3: Long section through the Ming Mine showing the location of drill platforms and drilling reported in the ASX announcement dated 17 July 2025. Assay results greater than 0.5% Cu are shown in red.

Resource Conversion Drilling from the 805L Exploration Drive

Drilling from the 805L drill drive focused primarily on upgrading the data density in the high-grade copper-gold dominated VMS lenses defined by previously reported exploration drilling. The results demonstrate strong continuity and consistent high grades in the Ming North and South VMS lenses in addition to the FWZ (where targeted).

Drilling from the 805L was predominantly completed from the 805L Crosscut 3 West, 805 Escapeway Access and the 850L stockpile (Figure 3).

Figure 4: Isometric view of drill positions in the 805L Exploration drill drive. Drill results from the ASX announcement dated 17 July 2025 are shown with copper assays >0.5% shown in red.

STEP-OUT DRILLING FOR MINERAL RESOURCE GROWTH

During the quarter, FireFly conducted step-out drilling from the end of the Ming Mine exploration drive. Subsequent to the quarter, on 16 October 2025, it was announced that the results of such drilling extended the known mineralisation by 430m beyond previous drilling and more than 650m beyond the current MRE.

METALLURGICAL RESULTS

On 5 August 2025, FireFly announced results from a comprehensive metallurgical test program completed on ~1,500 kg of bulk samples of mineralisation from the Ming Mine at Green Bay, undertaken at the SGS Canada Inc. (SGS) metallurgical facility in Lakefield, Ontario.

The bulk samples for metallurgical testing incorporated representative samples of both the high-grade VMS lenses and the broader FWZ, and included numerous blend ratios to inform the economic studies.

The metallurgical test work is a key component of the economic studies currently underway, which will be incorporated into the Scoping Study⁶ due for completion in the March quarter of 2026.

Using an optimised flowsheet, metal recoveries to final copper concentrate from all samples averaged +98% for Copper, +75% for Gold and +78% for Silver. Subsequent gravity and conventional leach testing of the pyrite flotation tails improved precious metals recoveries, with gold recovery rising to +85% and silver to +84%.

These results are a significant improvement in comparison to recoveries attained by the previous operator through the small-scale 500ktpa Nugget Pond processing plant.

The improved gold recovery has the potential to enhance the economics of the upscaled restart, with the current MRE containing a total of 550koz of gold⁷ across all Mineral Resource categories, making it a significant contributor to potential future cash flow.

The ore proved metallurgically simple and amenable to conventional, low-cost processing, backed by favourable grindability (Bond Work Index of 10.4-11.4 kWh/t) and low abrasive index (0.1-0.18 g), suggesting lower than average power, maintenance and consumable costs.

These positive results will feed directly into refining processing design, cost models, and revenue assumptions in the upcoming economic and scoping studies.

ENVIRONMENTAL APPROVAL

FireFly is rapidly laying the foundations for a staged upscaled production restart at Green Bay.

As announced on 5 August 2025, FireFly has obtained a conditional environmental release (Environmental Release) from the Province of Newfoundland and Labrador that permits an initial upscaled restart of operations at Green Bay, with a processing plant throughput capacity of 1.8 Mtpa.⁸

As a result of this decision, no further detailed environmental and socio-economic assessments are required for that scale of restart, enabling FireFly to proceed toward construction permit applications and early works.

Applications for construction permits are underway, and early seasonal site preparation works are planned to begin in late 2025.

Ongoing environmental monitoring and closure planning are in progress, supported by external consultants to ensure compliance, including with the conditions of the Environmental Release.

The plant capacity is a technical specification forming part of the environmental submission and not a forecast of the estimated production of the mining operation. The mining operation’s forecast production will not be estimated until such time as the Company has prepared and announced its Scoping Study. Should a larger scale case be adopted than contemplated by the Environmental Release, further assessment may be required by government agencies.

ENGINEERING STUDY UPDATES

FireFly has engaged leading consultants to progress optimal mining and processing designs.

Conceptual mining studies by Entech recommend Transverse Long Hole Open Stoping (TLHOS) for the broader footwall zones and conventional Long Hole Open Stoping (LHOS) for the high-grade VMS zones, both utilising full backfill strategies to optimise extraction.

The Company is designing a paste backfill system that can encapsulate over 50% of tailings underground, offering both operational and environmental benefits.

Process engineering progress is also being advanced. Ausenco is refining the process flowsheet, incorporating the recent metallurgical testwork to guide design choices.

Preliminary design and trade-off studies for the tailings storage facility (TSF) have been completed by Knight Piesold, with final designs to be delivered in the coming months.   Sterilisation and geotechnical drilling in the proposed TSF and processing plant areas have confirmed favourable rock conditions and did not intersect mineralisation.

Newfoundland and Labrador Hydro is conducting the power supply studies which are due for completion before the end of the year. Existing high voltage hydro transmission lines traverse the property and are expected to play an important role in the future development of the upscaled production at the Ming Mine.

In March 2025, Natural Resources Canada (NRCan) announced conditional approval of contribution funding of the Green Bay Power Assessment Project through the Critical Minerals Infrastructure Fund. Subsequent to the quarter, on 2 October 2025, NRCan and FireFly signed a non-repayable contribution agreement for up to C$613,775 in funding to support the Project. This project will advance electrification studies to support the development of infrastructure required to expand critical minerals production in the Province of Newfoundland and Labrador.

The overall study timeline suggests completion of a Scoping Study⁹ in the March quarter of 2026. The Scoping Study will integrate the mining, processing, infrastructure and permitting elements into one cohesive economic assessment.

REGIONAL EXPLORATION AND GREENFIELDS COPPER-GOLD TARGETS

On 24 July 2025, the Company announced the results of a modern geophysical campaign over the central Green Bay Copper-Gold Project claims, which has identified 325 conductive anomalies potentially caused by copper-gold bearing sulphide mineralisation considered to be look-alikes to the known deposits (e.g. Ming, Rambler Main, East Mine). The surveys, comprising airborne electrical (VTEM) and magnetic data plus localised ground electromagnetic (EM) follow-up, represent the first modern regional geophysics over the area and strengthen the case for significant discovery upside.

Geophysics is a key exploration tool at Green Bay, with the mineralisation at the Ming deposit and other known deposits exhibiting strong responses to electromagnetic surveys due to the conductive nature of the chalcopyrite-rich sulphide mineralisation.

Many of the 325 anomalies occur as coherent trends that exhibit strong resemblance to known mineralisation in the district. Similarities include geological setting, orientation of the trends (North-East, similar to Ming), and magnitude of the conductive responses.

Due to the significant number of high priority new geophysical targets, FireFly has mobilised a second surface diamond drill rig and plans to accelerate surface exploration, particularly in prospective zones such as the Hillbog and Southwest areas adjacent to the Ming, Rambler, and East Mines. The Company plans to systematically drill test the high-priority anomalies beyond the known deposits to confirm the cause of the anomalous response, which could include copper and gold bearing sulphides.

Based on the strength of the targets generated, the Company intends to fast-track the surface discovery program with part of the proceeds of the recent capital raising.   A total of ~C$10 million raised via the issue of Canadian flow-through shares as part of the June 2025 equity raising (see ASX announcement dated 5 and 10 June 2025) has been allocated to discovery, targeting and testing of greenfields areas at Green Bay through to December 2026.

Recently, surface drilling has been focused on testing mineralisation proximal to historical deposits such as the Rambler Main and East Mines. Results previously announced from drilling at Main Mine included 10m @ 6.4% CuEq and 12.9m @ 4.3% CuEq (see ASX announcement dated 15 May 2025).

Figure 5: Multiple significant new targets from the recent airborne VTEM and magnetic geophysical surveys. The white dots represent bedrock conductive anomalies.  There are numerous untested conductive trends in a similar orientation (yellow boxes) to the known mineralisation at the Ming, Rambler Main and East Mines (white boxes).  So far, a total of 325 conductive responses have been identified which are significant and potentially caused by copper-gold bearing sulphide mineralisation.

Initial Targets

TILT COVE PROJECT

FireFly has commenced exploration at the recently acquired Tilt Cove Project, located approximately 30 km east of the Ming Mine. Tilt Cove is a large-scale copper-gold VMS system that historically produced around 170,000 t of copper and 50,000 oz of gold between 1864 and 1967, with limited modern exploration completed since.

Ground EM surveys have confirmed a strong, large-scale conductive anomaly (Figure 6) at the project, which is scheduled for drill testing later in 2025 (see ASX announcement dated 24 July 2025).

In addition, FireFly is completing a lease-wide airborne VTEM and magnetic survey over the project area, the first of its kind at Tilt Cove, with results to be reported as they become available (see ASX announcement dated 27 October 2025).

RAMBLER MAIN MINE AND EAST MINE AREA: HILLBOG TARGET

In addition to identifying the surface expression of both historical Rambler Main and East Mines, the airborne VTEM survey identified a large previously unknown look-alike anomaly 300m to the south of Rambler Main Mine, known as Hillbog (see ASX announcement dated 24 July 2025).

Drilling of this target has commenced.

SOUTHWEST TARGET AREA

In the Southwest portion of the Green Bay Project, approximately 8 km SW of Ming Mine, a series of large untested EM anomalies have been defined in prospective volcanic rocks (Figure 6). The area is covered by glacial sediments and boulders with very little outcropping exposures. The EM response is similar to known mineralisation within past producing copper mines on FireFly’s land package.

Figure 6: Tilt Cove Copper-Gold Project area showing the large-scale conductor (red) identified by FireFly’s ground-based EM survey. This conductor is significant and potentially caused by copper-gold bearing sulphide mineralisation. These results confirm an anomaly earlier identified in a 1983 EM survey completed by Newmont Exploration.  The anomaly has yet to be drill tested and will be the subject of maiden drilling later in 2025.

FORWARD WORK PLANS

Near-term drilling activities at the Green Bay Copper-Gold Project will continue to focus on three key areas: Mineral Resource Growth, Upgrading the Mineral Resource (with infill drilling results) and New Discoveries from both underground and surface. At 30 September 2025, the Company had completed 251 drill holes for ~123,064 metres of underground diamond drilling. A total of six underground rigs will continue to advance the underground Mineral Resource growth and development activities. Additionally, a second surface drill rig has been mobilised to fast-track surface regional discovery.

Green Bay (Ming Mine) Mineral Resource Growth and Development

The low-cost Mineral Resource growth strategy is underpinned by the 805L exploration drill drive at the Ming Mine. The Company has invested in 2,335 metres of underground exploration and ancillary development since acquisition of the project in October 2023 to provide drill platforms to accelerate growth and discovery from underground. The second phase of 805L Exploration drive has been completed, providing locations for both infill drilling and further down-plunge Mineral Resource extension. Underground drilling from the drill drive is currently underway to test the Ming mineralisation up to 650m beyond the current Mineral Resource boundary. Subsequent to the quarter, on 16 October 2025, it was announced that initial results of such drilling extended the known mineralisation by 430m beyond previous drilling and more than 650m beyond the current MRE.   The relevant results included:

• 49.0m @ 6.1% CuEq (4.9% Cu & 1.3g/t Au) in hole MUG25-202 (~39.2m true thickness), including 14.3m @ 13.7% CuEq (10.6% Cu & 3.2% Au) (see ASX announcement dated 16 October 2025).
  

Development of additional platforms for further ongoing exploration and infill drilling will continue at Ming throughout 2025.

Upgrading the MRE remains a key priority for the Company’s plans to resume upscaled mining at Green Bay. Infill drilling is expected to upgrade the Inferred Resource (34.5Mt @ 2.0% CuEq) at Ming to the higher quality M&I Resource categories which currently stand at 24.4Mt @ 1.9% CuEq¹⁰.

Based on results to date, it is likely that the amount of mineralisation classified as M&I will increase in the MRE update currently planned by year-end 2025.¹¹ This will be important for future economic studies.

Economic evaluation of the proposed upscaled resumption of production at Green Bay is in full-swing. Key consultants have been appointed to complete the economic studies, including Entech, Ausenco, Stantec and Knight Piesold. SGS have completed comprehensive metallurgical test work on samples of both VMS and footwall stringer-style mineralisation. The results have demonstrated considerable improvement (see ASX announcement dated 5 August 2025). Such results are expected to be a catalyst for ongoing discussions with potential offtake groups interested in securing the high-quality copper-gold concentrate expected to be produced from the Ming Mine. Various scenarios for an upscaled restart to operations are being evaluated. With the huge success of the drilling programs to date, the Company wishes to avoid unnecessarily limiting the size of any future potential upscaled mining operation until it has completed the next phase of growth drilling.

The first economic studies are currently planned for completion in Q1 2026.¹⁰

Having received from the Environmental Release from the Newfoundland and Labrador Department of Environment and Climate Change, FireFly will has now commenced applying for early works and construction permits.

Green Bay (Ming Mine) Regional Discovery

Based on the quality of targets identified, the Company is accelerating the regional discovery program at Green Bay over the next 6-12 months.

Surface drilling during 2025 has focused on extensions of mineralisation at Rambler Main Mine. Further assay results from this program are expected in the coming weeks. The second surface rig is testing targets beyond the known deposits. Key priority areas to be tested include the Hillbog prospect and Southwest target area.

Geophysics is a key exploration tool at Green Bay, with the mineralisation at Ming and other known deposits exhibiting strong responses to electromagnetic surveys due to the conductive nature of the chalcopyrite-rich sulphide mineralisation.

Targets identified by recent VTEM surveys are scheduled to be systematically drill tested in upcoming exploration drilling campaigns through to December 2026.

Exploration will also ramp up at the Company’s Tilt Cove Project. Follow-up drill testing of the conductive anomaly, that was confirmed by ground-based EM, is scheduled before the end of 2025.

PICKLE CROW GOLD PROJECT

No field activities were undertaken by the Company at the Pickle Crow Gold Project during the quarter due to the team’s focus on the development and exploration activities at the Green Bay Copper-Gold Project.

As announced on 30 April 2025, the Company appointed BMO Capital Markets to assist with a strategic review with respect to the Company’s 70% interest in the high-grade Pickle Crow Gold Project (Strategic Review). The objective of the Strategic Review is to evaluate options to maximise value for shareholders and allow the Company to focus on progressing the Green Bay Copper-Gold Project. The BMO-led Strategic Review, including a thorough evaluation of strategic alternatives and recommendations to maximise shareholder value, is being evaluated and finalised. A conclusion is expected to be completed and released to the market by the end of 2025.

Investors are cautioned that there is no guarantee that the Strategic Review will result in the divestment of all or any part of the Company’s interest in the Pickle Crow Gold Project and the Company will otherwise keep the market updated in accordance with its continuous disclosure obligations.

CORPORATE
S&P/ASX 300 Index
On 5 September 2025, the Company was announced by S&P Dow Jones Indices as an addition to the S&P/ASX 300 Index, effective prior to the open of trading on 22 September 2025, as a result of the September quarterly review.

FINANCIAL OVERVIEW
Share Purchase Plan (SPP)
On 11 July 2025, FireFly announced that due to strong investor demand it had doubled its SPP from A$5.0 million to A$10.0 million. The SPP was completed on 14 July 2025, with the issue of 10,416,666 ordinary fully paid shares in the Company (New Shares).

The SPP was undertaken concurrently with the Company’s broader equity raising of ~A$98.1 million comprising the following components (together, the Equity Raising):

• ~A$11.2 million (~C$10.0 million) charity flow-through placement to Canadian investors at a price of approximately A$1.49 per share (Charity Flow-Through Placement) which completed on 13 June 2025 with the issue of 7,559,539 New Shares;
• ~A$54.9 million two-tranche institutional placement at a price of A$0.96 per share (Institutional Placement) of which the first tranche completed on 16 June 2025 with the issue of 28,064,281 New Shares and second tranche completed on 3 September 2025 with the issue of 29,166,667 New Shares; and

Metal equivalents for Mineral Resource Estimates
Metal equivalents for Mineral Resource Estimates have been calculated at a copper price of US$8,750/t, gold price of US$2,500/oz and silver price of US$25/oz. Individual Mineral Resource grades for the metals are set out in Appendix A of this announcement. Copper equivalent was calculated based on the formula: CuEq(%) = Cu(%) + (Au(g/t) x 0.82190) + (Ag(g/t) x 0.00822).

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 calculations have a reasonable potential to be sold and recovered 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.

Metal equivalents for Exploration Results
Metal equivalents for 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 grades for the metals are set out in the ASX announcements in which the Exploration Results were first reported by the Company.

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% based on historical recoveries achieved at the Ming Mine in addition to historical metallurgical test work to increase recoveries. Zinc recovery is applied at 50% based on historical processing and potential upgrades to the mineral processing facility.

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 the Company’s operational experience.

Copper equivalent was calculated based on the formula CuEq(%) = Cu(%) + (Au(g/t) x 0.82190) + (Ag(g/t) x 0.00822) + (Zn(%) x 0.15038).

Exploration Results
The Exploration Results referred to in this announcement were first reported by the Company in the ASX announcements cross-referenced in this announcement.
