FireFly Managing Director Steve Parsons said: “These exceptional new results from extensional drilling set the scene for our resource update, which is on track for delivery this month.
”Our recent drilling has confirmed that mineralisation at the Ming underground mine extends a further 650m from the existing Resource and remains open, validating our strategy of delivering rapid, low-cost resource growth via the drill bit.
“With the funds from the recent institutional placement, we are well-placed to fast-track our growth strategy of resource growth and new discovery drilling.
“This concerted drilling effort is intended to allow us to unlock the full size potential of the Green Bay copper-gold project”.
FireFly Metals Ltd (ASX: FFM) is pleased to announce more strong drilling results which further extend the known mineralisation at the Green Bay copper-gold project ahead of the impending resource update.
There are two distinct styles of mineralisation at the Ming underground mine at Green Bay. One comprises the upper copper-gold rich Volcanogenic Massive Sulphide (‘VMS’) lenses. This sits above a broad copper stringer zone known as the Footwall Zone (‘FWZ’).
FireFly’s strategy of delivering rapid resource growth via the drill bit is well underway, with four drill rigs operating from the underground exploration drive positioned to test the mineralised system outside the Resource, which currently stands at 39.2Mt @ 2.1% for 811,000t CuEq.[1]
Outstanding drill results have been returned from resource extension drilling targeting both the upper high-grade copper-gold VMS zone and the underlying broad-scale copper FWZ. Key results from the upper VMS zone include 17.8m @ 4.2% CuEq and 22.2m @ 5.1% CuEq.
Thick, consistent mineralisation continues to be discovered in the FWZ, with highlights including 56.8m @ 2.7% CuEq, 31.7m @ 3.5% CuEq and 61.8m @ 1.8% CuEq.
These new results are considered to be highly significant because both the high-grade VMS mineralisation and the broad copper stringer zone have been extended more than 200m beyond the limits of historic exploration drilling, which returned a previous intersection of 102m @ 1.7% Cu.
The mineralisation remains open, and drilling continues to demonstrate the world-class growth potential of the Green Bay copper-gold project.
These new results also confirm the presence of high-grade copper and gold mineralisation in down-hole electromagnetic anomalies identified during the recent geophysical surveys completed by the Company (see ASX release dated 16 September 2024).
1 The Company first announced the foreign estimate for the Green Bay Project on 31 August 2023. The foreign estimate is prepared in accordance with Canadian National Instrument 43-101 and has not been reported in accordance with JORC 2012. A competent person has not done sufficient work to classify the foreign estimates in accordance with the JORC Code and it is uncertain that following evaluation and or further exploration that a foreign estimate will be able to be reported in accordance with the JORC Code. Further information on the foreign estimate is set out in Appendix A.

About the Drill Results
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, the Company has completed 79 drill holes for 37,110m of diamond core to date from underground development.
Assays have been received for the first 68 holes drilled by FireFly. Logging and analysis of the remaining 11 drill holes is ongoing, with details to be reported regularly as results are received.
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 1.85km and it remains open down-plunge.

The new results reported in this release are from holes completed by FireFly from the initial Phase One 750m exploration drive that will ultimately extend to 1,500m of drill drive development.
Development Drive Drilling (from the 805L)
Development of a 1,500m exploration drive continues, with Phase One (750m) completed. Four drill rigs are currently operating underground, with three rigs deployed in the northernmost cross-cuts drilling extensional holes that will be incorporated in the Resource update scheduled for October 2024.
This release contains results from a further 15 drill holes completed from the first two drill platforms completed in the drill drive and from the existing mine development. All holes demonstrate the presence of both VMS and FWZ-style mineralisation, confirming continuity for >700m beyond the current underground workings.

Growth Outlook
The development of the Phase One 750m drill drive has been completed.
Phase Two has now commenced, which consists of a further 1,200m of planned development to enable further step-out resource growth. The owner-operator mining crew have completed 1,488m of lateral development (including ventilation and secondary egress) since the recommencement of underground mining.
Four rigs continue to operate underground with a focus on extensional resource growth drilling.
All assay data to be incorporated in the impending Mineral Resource update has now been received. The revised Mineral Resource Estimate remains on track for delivery during October 2024. Regional exploration drilling will now commence, with airborne geophysical surveys well underway and drill testing over the coming months.
FireFly remains well-funded for its accelerated growth strategy following the recent highly successful A$65M institutional placement; Firefly has also announced its intention to undertake a non-underwritten Share Purchase Plan (‘SPP’) to raise an additional ~A$5M.

COMPLIANCE STATEMENTS
– Foreign Resource Estimate Green Bay Project
The Company first announced the foreign estimate of mineralisation for the Green Bay Project on 31 August 2023. The Company confirms that the supporting information included in the announcement of 31 August 2023 continues to apply and has not materially changed.
Metal equivalents
Metal equivalents for the foreign estimate of mineralisation have been calculated at a copper price of US$8,295/t, gold price of US$1,912/oz and silver price of US$22.59/oz. Individual grades for the metals are set out at Appendix A of this announcement. Copper equivalent was calculated based on the formula CuEq(%) = Cu(%) + (0.74112 x Au(g/t)) + (0.00876 x Ag(g/t).
Metal equivalents for the drilling at the Green Bay Project have been calculated at a copper price of US$8,300/t, gold price of US$2,000/oz, silver price of US$25/oz and zinc price of $2,500/t. Individual grades for the metals are set out at Appendix B of this announcement. Copper equivalent was calculated based on the formula CuEq (%) = Cu(%) + (Au (g/t) x 0.77472) + (Ag (g/t) x 0.00968) + (Zn (%) x 0.3012).
No metallurgical recovery factors have been applied to the in-situ resource nor drill hole results. It is the Company’s view that all elements in the copper equivalent calculation have a reasonable potential to be recovered and sold.

Rambler held a 100% interest in the Ming property and between 2005 and 2023 and conducted a multi-phase diamond drilling program consisting of surface drilling, directional drilling, and underground delineation drilling. A total of 220,704m from 1,365 diamond drill holes were completed by Rambler. Between 2012 and 2022 the Ming mine produced 3Mt at 1.86% Cu and 0.71 Au for total of 55Kt of copper and 68Koz of gold.

| Geology | • | Deposit type, geological setting and | • | The Green Bay project is a Noranda-type |
| style of mineralisation. | Volcanogenic Massive Sulfide (VMS) hosted by | |||
| Cambrian-Ordovician metavolcanic and | ||||
| metasedimentary rocks of the Pacquet Harbour | ||||
| Group. The style of mineralization, alteration, host | ||||
| rock, and tectonism most closely resembles other | ||||
| VMS deposits throughout the world. The deposit | ||||
| consists of several individual massive sulphide | ||||
| lens and their underlying stockwork zones. It is | ||||
| thought that the stockwork zone represents the | ||||
| near surface channel ways of a submarine | ||||
| hydrothermal system and the massive sulphide | ||||
| lens represents the accumulation of sulphides | ||||
| precipitated from the hydrothermal solutions, on | ||||
| the sea floor, above and around the discharge | ||||
| vent. The Ming deposits are polymetallic (Cu, Au, | ||||
| Ag ± Zn) massive sulphides that occur along the | ||||
| flank of a felsic dome. The Ming deposits have | ||||
| undergone strong deformation and upper | ||||
| greenschist to amphibolite facies metamorphism. | ||||
| The massive sulphide bodies are now thin and | ||||
| elongate down the plunge of the regional lineation | ||||
| (30-35ºNE). Typical aspect ratios of length down- | ||||
| plunge to width exceed 10:1, and the bodies exhibit | ||||
| mild boudinage along the plunge. The foot wall | ||||
| stock work comprises mainly of quartz-sericite- | ||||
| chlorite schist, which hosts disseminated and | ||||
| stringer pyrite and chalcopyrite with minor | ||||
| sphalerite, galena, and pyrrhotite with locally | ||||
| significant gold contents that could represent a | ||||
| discordant stockwork stringer feeder zone. The | ||||
| mineralization is crosscut by younger mafic dykes. |
