Lightning Minerals’ Managing Director Alex Biggs said , “We are excited that we continue to gain confirmation of high-grade epithermal gold mineralisation at Mt Turner. The purpose of this first drill campaign is to do exactly that and we are very pleased with what we are seeing. The Mt Turner project is a very target rich environment which we have proven with the discovery of large scale, high-grade zinc-lead-silver mineralisation at the Cobar prospect which is related to the Mt Turner porphyry system. This is an important step in our exploration at Mt Turner as we are planning to target the Mt Turner porphyry in our next drill campaign. We still have pending results from drilling at Pit 6, the Rocky Reward prospect, which we are excited to see. That will round out our drilling assays from our inaugural drilling campaign at Mt Turner and a very successful first program. Also pending are assays from our soil and rock sampling which will further assist in drill targeting for the next round of drilling.

“ We believe we are on to defining a significant gold system at Mt Turner with the added benefit of the Mt Turner porphyry now under investigation with potential for copper and other base metals now a real possibility. The team is underway planning follow up drilling for what we feel is an exceptional opportunity for the Company, particularly when we begin to compare our rhyolite intrusive thesis and mineralisation styles to proven, large-scale projects such as the Cargo porphyry deposit in New South Wales, Australia. The scale, mineral system and potential at Mt Turner is a strong impetus for the Company to accelerate its exploration efforts”.

Mt Turner - Multiple Intersections Confirm Gold and Base Metals

Recent assay results from holes four to six of a nine-hole program at the Company’s wholly owned Mt Turner Project continue to demonstrate significant epithermal gold potential along the Drummer Fault including assays from Pit 5 (Drummer Girl) yielding:

– Hole L1MP5DD002 (Pit 5 Drummer Girl)

3.9m @ 3.6g/t Au and 8.8g/t Ag from 90m Incl. 1.0m @10.7g/t Au and 17.4g/t Ag from 90m

Additional intersections include:

– Hole L1MP5DD003 (Pit 5 Drummer Girl)

3.0m @ 2.8g/t Au and 7.5g/t Ag from 105m

Incl. 1.0m @ 6.3g/t Au and 17.2g/t Ag from 105m

Drilling at the Cobar prospect has intersected high-grade zinc-lead-silver mineralisation, related to the Mt Turner porphyry system which will be targeted for further drilling during a phase 2 program in 2026. Results include:

Hole 25L1MCOBDD001 (Cobar)

17.2m @ 6.2% Zn, 1.4% Pb and 10.3g/t Ag from 32m, Incl. 4.5m @ 11.6% Zn, 0.5% Pb and 12.4g/t Ag from 43.8m

Multiple zones of mineralisation along the Drummer Fault remain open along strike and at depth. Results are pending for the final two holes of the drill program at Pit 6 (Rocky Reward). The current drill program was primarily focused on shallow mineralisation, down to approximately 100m below surface. The highly encouraging results from the drill program to date provide strong impetus for the Company to potentially define a significant gold system and further its exploration activities across the broader project area. Followup drilling is being planned to target mineralisation down dip and along strike from recent intercepts and the Mt Turner porphyry system for copper, gold and base metals.

Further High-Grade Gold Intersections Confirm Shallow Gold Potential

Drill hole 25L1MP5DD002 was designed to test for epithermal mineralisation extensions adjacent to and below the historic Drummer Girl (Pit 5) open pit. Two occurrences of epithermal mineralisation were encountered at 67m and 90m down hole (Figure 1):

Hole 25L1MP5DD002 (Pit 5 – Drummer Girl)

3.9m @ 3.6g/t Au and 8.8g/t Ag from 90m

Incl. 1.0m @ 10.7g/t Au and 17.4g/t Ag from 90m

1.0m @ 7.2g/t Au and 10.4g/t Ag from 67m

Mineralisation is associated with quartz and sulphide veins in highly altered diorite, in contrast to mineralisation observed in holes 25L1MP5DD001 and 25L1MP5DD003 which was associated with fault breccia zones, (Figure 2). All diorite intersections in drill core are now being analysed for additional mineralisation potential.

Wide, High-Grade Zn-Pb-Ag Mineralisation Identified at Cobar

Drill Holes 25L1MCOBDD001 (Figure 5) and 25L1MCOBDD002 (Figure 6) intersected the base metal zone of the Mt Turner porphyry system encountering high grade zinc, lead and silver mineralisation. The Cobar prospect is located approximately 4km south of the Drummer Fault on the southern side of the Mount Turner porphyry system.

Hole 25L1MCOBDD001 (Cobar)

Incl. 0.6m @ 19.7% Zn, 8.4% Pb, 150g/t Ag and 0.2g/t Au from 22.65m

Inspection of the core in hole 25L1MCOBDD002 identified a late stage miarolitic cavity lined by drusy quartz suggesting proximity to an epithermal system that may host significant high-grade gold potential (Figure 4).

The Cobar prospect comprises a north-south one-kilometre line of 19[th] Century workings through a rhyolitic breccia corridor that hosts mesothermal base-metals with areas of epithermal Au/Ag overprint. The current thesis on mineralisation is that The Mt Turner porphyry was formed along intersecting north-west/north-east

fractures. North-south tension cracks developed and filled with dolerite rock, with rhyolite rock later intruding into the same cracks. Both rock types fractured extensively and filled with metal sulphides (mainly sphalerite, galena and chalcopyrite) at medium temperatures. In some areas a final low-temperature event deposited gold and silver bearing quartz.

Mt Turner Project Location and Prospectivity

The Mt Turner Project is located 15km to the northwest of Georgetown in North Queensland. The Project is held through granted Exploration Permits (EPM 27170 and EPM 27525) The Drummer Fault structure, a 14 km east-west structure readily visible on LiDAR and satellite imagery is a key feature of the terrain Historically, several shallow oxide pits were mined for gold in the 1990’s along the Drummer Fault. In addition, northeast trending structures have intersected the Drummer Fault in numerous locations. These structures have potential to form higher-grade mineralisation and are thus a high priority target. There are multiple existing mineralised targets along the Drummer Fault and below the current open pits.

Prior drilling[1] has been completed by Essex Minerals Inc[2] during 2021, Union Mining NL[3] in the 1990s, and CRA Exploration Ltd[4] in the late 1980’s intersecting multiple gold lodes with positive results including 16m l 6 505 Little Collins St Melbourne VIC 3000 Australia | admin@lightningminerals.com.au | (08) 9429 8806 @ 3.56 g/t Au (Hole UMDT95_D04), 16.0m @ 3.60g/t Au (Hole UMDT95_D03), 12m @ 6.5g/t Au (Hole UMDT95_D03) and 6m @ 2.9g/t Au (Hole PD86_RR2). These results formed the basis for shallow oxide open pit mining across six open pits in the 1990’s. Minimal exploration has occurred beneath the historical open pits but multiple targets exist with shallow mineralisation intercepts of up to 7.0m @ 1.74g/t Au and 67.7g/t Ag from 64m downhole (Hole 21ISMP3RC001).

Geology and Mt Turner Potential – An Evolving Thesis

The Permo-Carboniferous, Mt Turner Porphyry System is a multi-stage felsic magmatic event localised by NW-NE conjugate faults. The system is characterised by a number of felsic quartz eye intrusive stocks and associated rhyolite dyke swarms that emanate some distance from the intrusive centre. These rhyolite dykes are analogous with the type of rock associated with large copper and gold deposits. Analogous points of comparison are under investigation to assist in further thesis development.

The Mt Turner Porphyry System hosts a 6-kilometre diameter magmatic hydrothermal system characterised by a pervasive alteration halo with historical soil data displaying a classic porphyry metal zoning pattern from an inner Cu-Mo core surrounded by a gold-silver-base metal zone (Figure 9). Proximity to the east-west trending Drummer Hill fault structure has provided a large-scale fluid flow pathway for the porphyry related hydrothermal system to operate in, generating near surface epithermal gold and silver deposits peripheral l 6 505 Little Collins St Melbourne VIC 3000 Australia | admin@lightningminerals.com.au | (08) 9429 8806 to the porphyry system itself.

The Company has adopted a targeted exploration model whereby peripheral structures and breccia bodies may host significant precious metal low temperature epithermal style mineralisation. Structural analysis from geophysics and acquired LiDAR topography has demonstrated the existence of a number of prospective peripheral structures and breccia bodies interacting with rhyolite volcanics. Prospective structures were rated on the basis of strike length, historical mining, host rock lithology (Proterozoic basement mafic rocks were considered high priority) and proximity to the Mt Turner porphyry system.

The 14-kilometre east-west trending, regional Drummer Fault and associated splay structures was considered to be of the highest priority. The fault has been intruded by Permo-Carboniferous sub-volcanics and volcanic lithologies with wide -ranging compositions and alteration intensity from mafic dykes to rhyolite to fine grained granite. Fault splays, tensional jogs and horse-tailing have been recognised from analytical signal aero-magnetics which indicates potential tensional zones conducive for mineralisation. The current drilling program is testing some of these prospective tensional zones along the fault.

The second structure prioritised during this initial program was the Cobar Line Structure (Cobar prospect) consisting of a kilometre long north south feature associated with the Mt Turner rhyolite dyke swarm immediately south of the porphyry system within the gold-silver-base metal zone.

Next Steps – Defining the Scale Potential at Mt Turner

Assays are now pending for the final two holes of the drill program which have been drilled at Pit 6 (Rocky Reward). This is six kilometres west of Pit 5 (Hole25L1MP3DD001) where previous drilling has not yet tested l 6 505 Little Collins St Melbourne VIC 3000 Australia | admin@lightningminerals.com.au | (08) 9429 8806 extensions to mineralisation below and along strike from the existing open pit

Soil and rock chip sampling has been completed along the Drummer Fault and over prospects of interest, identified through field reconnaissance and mapping, assay results are pending. These results will further assist in supporting a larger scale targeting exercise on prospects within the broader Mt Turner Project area.

The Company’s geology team is now working to define a follow up drill program further expanding on the areas already identified, both at depth and along strike. Thesis development is also underway to determine relationship between the Mt Turner porphyry, the Cobar zinc-lead-silver discovery and the gold emplacement along the Drummer Fault. Confirmation of multiple gold and base metal occurrences have demonstrated the scale and potential of the Mt Turner project and its highly target rich environment.

In other cases more explanation may be required, such as where there is coarse gold that has inherent sampling problems. Unusual commodities or mineralisation types (eg submarine nodules) may warrant disclosure of detailed information.	With respect to the 2025 drilling by Lightning Minerals • Drilling consisted of 7 HQ diamond holes. • All samples were processed in Townsville by ALS Global, an independent accredited laboratory. Gold assays were completed by 50g screen fire assay with atomic absorption finish. Silver and 33 multi-element analysis was undertaken by a four-acid digest followed by inductively coupled plasma atomic emission spectroscopy (ICPAES). With respect to the 2021 drilling by ISMINS on behalf of Essex Minerals2 • Drilling consisted of two HQ diamond holes with RC pre-collars, the remaining four holes were completed as Reverse Circulation using a 4.5-inch drill bit, and a cone splitter. • All samples were processed in Townsville by ALS Global, an independent accredited laboratory.

Whether logging is qualitative or quantitative in nature. Core (or costean, channel, etc) photography. The total length and percentage of the relevant intersections logged.	With respect to the 2025 drilling by Lightning Minerals • The drill core has been qualitatively logged by geologists with experience in orogenic, epithermal and porphyry mineralisation systems. The diamond core logging has recorded colour, texture, grainsize, weathering, alteration and minerals present in the drill core. The reported drill holes have been logged in full. • Core has been photographed in the wet form. Core photography is currently ongoing. With respect to the 2021 drilling by ISMINS on behalf of Essex Minerals2 • The RC chips have been qualitatively logged by geologists with experience in orogenic, epithermal and porphyry mineralisation systems.

Sub-sampling techniques and sample preparation	If core, whether cut or sawn and whether quarter, half or all core taken. If non-core, whether riffled, tube sampled, rotary split, etc and whether sampled wet or dry. For all sample types, the nature, quality and appropriateness of the sample preparation technique. Quality control procedures adopted for all sub-sampling stages to maximise representivity of samples. Measures taken to ensure that the sampling is representative of the in situ material collected, including for instance results for field duplicate/second-half sampling. Whether sample sizes are appropriate to the grain size of the material being sampled.	With respect to the 2025 drilling by Lightning Minerals • The drill core was drilled with HQ3 size and sampled as complete half core to produce bulk sample for analysis. Intervals selected varied from 0.4m to 1.6m (minimum-maximum), with a nominal sample length of 1m. The core is cut in half length ways just to the right of the orientation line where available using a diamond core saw. All samples are collected from the same side of the core where practicable. Assay preparation procedures ensure the entire sample is first crushed coarse crushed, then fine crushed to better than 85% mass passing 3.15mm screen sizing, with a 250g rotary split taken and pulverised to 75 microns, from which a sub‐sample is taken for analysis. This removes the potential for the significant sub‐ sampling bias that can be introduced at this stage. • No second-half sampling of the core has not been undertaken.

	Discuss any adjustment to assay data.	• Assay values below half detection limit were assigned a grade of half the detection limit.
Location of data points	Accuracy and quality of surveys used to locate drill holes (collar and down-hole surveys), trenches, mine workings and other locations used in Mineral Resource estimation. Specification of the grid system used. Quality and adequacy of topographic control.	• Handheld Garmin GPS instruments were used to geo locate each drill collar location, these instruments are understood to be accurate within a ±5m in the horizontal and vertical planes. Drill hole collar locations will be recorded by a licensed surveyor upon completion of the drilling program. • The level of topographic control is provided by a LiDAR survey flown in 2020, with an expected horizontal accuracy of ±0.05m and vertical accuracy of ±0.5m. • A compass clino has been used to align the drill rig, with a downhole north seeking gyro-based system used for downhole measurements on all holes, hole deviation is minimal and within acceptable tolerances. • All collar locations were recorded in GDA94 Zone 54.
Data spacing and	Data spacing for reporting of Exploration Results.	• Exploration holes are orientated as best possible to intersect the Fault Breccia System. 1m downhole sample spacing is considered appropriate for the reporting of the exploration diamond drilling assay results. • No Mineral Resource or Ore Reserve Estimates have been completed. • Interval length weighted compositing has been used to generate significant intercept grades.
distribution	Whether the data spacing, and distribution is sufficient to establish the
	degree of geological and grade continuity appropriate for the Mineral
	Resource and Ore Reserve estimation procedure(s) and classifications
	applied.
	Whether sample compositing has been applied.
Orientation of data in relation to geological structure	Whether the orientation of sampling achieves unbiased sampling of possible structures and the extent to which this is known, considering the deposit type. If the relationship between the drilling orientation and the orientation of key mineralised structures is considered to have introduced a sampling bias, this should be assessed and reported if material.	• The drilling has been designed to intercept the downdip orientation of the mineralisation at a perpendicular angle, with sampling size designed to delineate grade variability across the mineralisation. • The drilling orientation relative to key mineralised structures is not thought to have introduced any material sampling bias.
Sample security	The measures taken to ensure sample security.	• Samples are collected from the drill rig and processed at a facility in Georgetown. Samples are then driven by representatives of the company into Cairns, where they are freighted directly to the receiving laboratory in Townsville. The companyhas no reason to suspect anytamperingwith the samples.
Audits or reviews	The results of any audits or reviews of sampling techniques and data.	• No audits or reviews of sampling techniques have been conducted to date.

Section 2 - Reporting of Exploration Results

iteria	JORC Code explanation	Commentary
Mineral tenement and land tenure status	Type, reference name/number, location and ownership including agreements or material issues with third parties such as joint ventures, partnerships, overriding royalties, native title interests, historical sites, wilderness or national park and environmental settings. The security of the tenure held at the time of reporting along with any known impediments to obtaining a licence to operate in the area.	• The ‘Mt Turner’ Tenements are in the process of being transferred to Lightning Minerals Ltd from FNQ Resources Pty Ltd (the project vendors) in accordance with agreement entered into in June 2025. • The Mt Turner Project includes exploration licences EPM27525, and EPM27170. • The Tenements are considered to be in good standing at the time of this announcement. • 3% NSR from all minerals on theproperty payable to Optegra Ventures Inc
Exploration done by other parties	Acknowledgment and appraisal of exploration by other parties.	• Exploration undertaken by prior parties includes: • Essex Minerals 2020-2022 • Meryllion Resource Corp 2020-2022 • KNX Resources Australia 2015-2020 • Mega Uranium 2006-2014 • Union Mining 1993-2003 • CRA Exploration 1985-1990
Geology	Deposit type, geological setting and style of mineralisation.	• The Mt Turner Project is prospective for Epithermal and Orogenic gold, silver and base metals, and Porphyry hosted copper and molybdenum.
Drill hole Information	A summary of all information material to the understanding of the exploration results including a tabulation of the following information for all Material drill holes: o easting and northing of the drill hole collar o elevation or RL (Reduced Level – elevation above sea level in metres) of the drill hole collar o down hole length and interception depth, o hole length. If the exclusion of this information is justified on the basis that the information is not Material and this exclusion does not detract from the understanding of the report, the Competent Person should clearly explain why this is the case.	• See main body of the announcement, Figures 1 – 9 and Tables 1 – 2.
Data aggregation methods	In reporting Exploration Results, weighting averaging techniques, maximum and/or minimum grade truncations (eg cutting of high grades) and cut-off grades are usually Material and should be stated. Where aggregate intercepts incorporate short lengths of high-grade results and longer lengths of low grade results, the procedure used for such aggregation should be stated and some typical examples of such aggregations should be shown in detail.	• Exploration results have been weight averaged using sample interval length.
Relationship between mineralisation widths and intercept lengths	These relationships are particularly important in the reporting of Exploration Results. If the geometry of the mineralisation with respect to the drill hole angle is known, its nature should be reported. If it is not known and only the down hole lengths are reported, there should be a clear statement to this effect(eg ‘down hole length, true width not known’).	• Drill holes are designed to intersect the down dip direction of the Drummer Fault system as close to perpendicular as possible. All reporting in the body of text above adequately describes intercepts as ‘downhole lengths’ and not true width.
