STRONG IP RESULTS ACROSS YANDAL PROJECT

IP SURVEY REFINES KEY TARGET AT MUSTANG-PONY AS WELL AS ACROSS THE DUSK ‘TIL DAWN AREA

HIGHLIGHTS

• Recently completed IP survey produced excellent results across two of Gateway’s key target areas, Dusk 'til Dawn and Mustang-Pony.

• A strong chargeability anomaly has been modelled at Haflinger in an area with high structural complexity – favourable setting for further gold mineralisation.

• Modelling of the Dusk ‘til Dawn intrusive units and associated chargeability and resistivity anomalism has provided key data for the upcoming diamond drilling program.

• Diamond drilling to commence this week – 4,600 metres planned.

• Gateway remains well capitalised to undertake planned 2025 and 2026 exploration, with cash and liquid ASX listed securities of approximately $12.1m as at the end of the June quarter, as well as having recently completed a $22.5m capital raising.

Management Comment

Gateway’s Executive Chairman, Mr Andrew Bray, said: “The recently completed IP survey produced anomalies precisely where we expected to see them. The survey was designed to map alteration and disseminated sulphides, as well as provide greater definition of key structures adjacent to the modelled intrusive units. This information provides critical input into the diamond drill program planning, which will commence this week.

On the Mustang-Pony trend, a 1km wide anomaly was modelled at the margins of the large Haflinger intrusive. This is an area of great structural favourability (convergence of shear zones, multiple northeast cross-cutting structures, intrusive unit, abundance of dilation zones, shear zone flexure, maficintermediate contact), and importantly historic drilling demonstrates the presence of gold in the system – HWRAB372, which was drilled right on the far western edge of the anomaly, intersected 16m @ 1.0g/t Au from 36m[1] , and HWRAB526, which is also on the outer edge of the anomaly and 100m away from HWRAB372, intersected 20m @ 0.6g/t Au from 48m to EOH (see Figure 2). All drilling in this area finished in weathered material, meaning the main structure remains entirely untested by drilling.

Two 3D surveys were conducted at Dusk ‘til Dawn over the eastern and western intrusive units. A very high chargeability response (>16msec) was modelled over 4km of strike, coinciding with shear zone flexures, multiple north-east cross cutting intersections, and the highest Au-Cu-Mo anomalism seen in the area. On the western trend, gold mineralisation appears to be associated with resistivity anomalies wrapping around the key sanukitoid margins.

Diamond drilling will commence in the coming days. The first hole to be drilled is at the Comanche prospect, which is at the northern end of the Dusk ‘til Dawn intrusive unit (see Figures 1 and 4). A 300mwide chargeability anomaly, which is indicative of sulphides, has been delineated within the shear zone and immediately adjacent to the intrusion margin. The anomaly also coincides with a north-east fault intersection.

A further update will be provided this week once diamond drilling has commenced.”

Introduction

Gateway Mining Limited (ASX: GML) ( Gateway or Company ) is pleased to provide an update on its Yandal Gold Project in Western Australia (Figures 5 and 6) and provide the results of Induced Polarisation (IP) surveys that have been completed across Pony-Mustang and Dusk ‘til Dawn. This work was undertaken by Moombarriga Geoscience and follows on from the recent gravity inversion modelling (please refer to ASX announcement of 9[th] September 2025) and bottom of hole (BOH) sampling that delineated several late-stage Mo-Bi-Te-Cu intrusions (sanukitoids), which Gateway believes are associated with the known gold mineralisation.

The aim of the IP survey was to map alteration, zones of disseminated sulphides, and critical structures adjacent to these major intrusive units, which are believed to be the key ingredients to large-scale Archaean orogenic gold deposits elsewhere across the Eastern Goldfields Terrain.

Given the scale of the historic BOH gold anomalism and alteration across the Eastern and Western intrusions across Dusk ‘til Dawn, it was decided that two 3-Dimensional IP surveys be completed along the strike of the combined 12km anomalous trend, with the aim of using the subsequent 3-Dimensional Inversion Modelling (undertaken by Terra Resources) to better enhance drill target testing. 2- Dimensional survey lines were completed across modelled (Mo-Bi-Te-Cu) intrusives to the north of Dusk ‘til Dawn (Comanche Prospect) and across the Haflinger prospect (Pony-Mustang target area). The results from this work is summarised below (Figure 1).

Figure 1: IP Survey locations

Haflinger Prospect (Mustang-Pony Target Area)

The Haflinger Intrusion is situated at the intersection of two regionally-significant shear zones, Celia and Mustang. This combined structural corridor consists of numerous second-order splay shears and interconnecting linkage structures. Structural complexity is further enhanced by flexures along the western margin of the Haflinger Intrusion, which are additionally transected by a suite of northeasttrending structures. The Company considers this structurally dynamic environment highly prospective for large-scale gold mineralisation, as the abundance of dilation zones is conducive to the emplacement of hydrothermal fluids and subsequent gold deposition.

The 2D IP survey at Haflinger was designed to traverse the intersection of three key structural elements: the shear convergence zone, a prominent northeast-trending fault, and a major flexure within the shear zone adjacent to the Haflinger Intrusion. The survey delineated a high chargeable anomaly approximately 1km in width (Figure 2), spatially coincident with this structural intersection (Figure 3), suggesting the presence of disseminated sulphides within the shear zone. Notably, the anomaly also coincides with the lithological contact between mafic and intermediate volcanic units – an interface recognised elsewhere within the Yandal Project as a favourable host for gold mineralisation.

Historic rotary airblast (RAB) drilling, conducted on wide spacing and to shallow depths west of the identified chargeability anomaly, returned encouraging gold intercepts including 16m @ 1.0g/t Au from 36m (HWRAB372)[2] and 20m @ 0.6g/t Au from 48m to BOH (HWRAB526) (Figure 2 above). Another hole 300m to the south returned 15m @ 0.9g/t Au from 68m to BOH (HWRAB913)[2] , potentially signifying a large lateral extent to the mineralisation footprint. Importantly, these holes terminated in weathered material and did not intersect the main shear structure or anomaly. Crucially, their positioning was offset

too far west, leaving the key structural intersection zone and the coincident 1km-wide IP anomaly entirely untested.

Comanche Prospect – (Dusk ‘til Dawn Target Area)

The Dusk 'til Dawn Northern Intrusion lies directly along strike from, and in the same stratigraphy as, the existing Dusk 'til Dawn Mineral Resource, where the shear zone dips beneath a strongly silicified, transported cap of dolomitic breccia. The principal target at Dusk 'til Dawn North is the flexure of the shear zone around the western margin of the Northern Intrusion, which is further dissected by a northeast-trending fault. A 2D IP survey was strategically positioned to image the zone where the flexured shear zone is intersected by this NE fault.

The survey identified a 300m-wide chargeability anomaly, indicative of sulphides, within the shear zone, located directly on the margin of the Northern Intrusion, with elevated chargeability coinciding with the NE fault intersection. Furthermore, resistivity data highlighted the position of the silicified cap, delineating it to a depth of approximately 40m. Historical aircore drilling in the area failed to penetrate the silicified cap, leaving both the shear zone and the associated chargeability anomaly untested.

The first hole of the upcoming diamond drilling program will be drilled at this prospect (Figure 4).

Western Intrusion - 3D IP Survey (Dusk ‘til Dawn Target Area)

The Dusk 'til Dawn Mineral Resource is hosted within a splay of the Celia Shear Zone, which flexures around the western margin of an intrusive body which recent petrology work classified as a sanukitoid. Sanukitoid intrusions are a common feature associated with multi-million ounce gold deposits across the Eastern Goldfields. Structural complexity is further enhanced by a northeast-trending fault that dissects the shear zone flexure.

Gold mineralisation at Dusk 'til Dawn is characterised by intense silica-potassic alteration, Au-Mo-Bi geochemical anomalism, and a white mica-kaolinite spectral signature. An outboard halo of pyrite alteration is present, with little to no pyrite observed in the mineralised zone. Collectively, the alteration and geochemical characteristics of the Dusk 'til Dawn deposit indicate a strong genetic link to the sanukitoid intrusion.

Gravity inversion modelling and hyperspectral analysis of drill chips across the broader Dusk 'til Dawn region have identified multiple analogous targets along the margin of the sanukitoid. The most prominent hyperspectral white mica-kaolinite anomaly is located on the eastern margin of the intrusion, where the same NE-trending fault that intersects the Dusk 'til Dawn deposit also cuts another splay of the Celia Shear Zone at a major flexure around the sanukitoid intrusion.

Results from the 3D IP survey reveal that the Dusk 'til Dawn deposit is situated within a resistivity anomaly that wraps around the sanukitoid margin, with increasing chargeability (and decreasing resistivity) outboard of mineralisation.

==> picture [76 x 46] intentionally omitted <==

This response is likely reflective of the alteration zonation that is characteristic of the Dusk 'til Dawn deposit, with a resistive silica-potassic core proximal to the sanukitoid, and increasing conductive pyrite outboard of mineralisation.

A second resistivity anomaly is present on the eastern margin of the intrusion, spatially aligned with the hyperspectral and geochemical analogue target – further supporting the potential for new gold discoveries within the Dusk 'til Dawn corridor and highlighting the importance of proximity to sanukitoids as a targeting criteria within the Yandal Project.

Eastern Intrusion – 3D IP Survey (Dusk ‘til Dawn Target Area)

The Dusk 'til Dawn Eastern Target is defined by an elongated gravity low anomaly extending over 8km of strike, interpreted to represent a series of intrusive bodies. Historical shallow RAB and aircore drilling across the area has delineated Au-Cu-Mo-Bi-Te-Ag anomalism over a 5km strike length, hosted within the sheared contact between volcaniclastics and the intrusions—referred to as the Django Shear.

The Django Shear displays multiple major flexures along the intrusion margins, with additional structural complexity introduced by cross-cutting northeast-trending faults.

The 3D IP survey has identified very high chargeability responses (>16 msec) on both margins of the intrusions that spans 4km of strike, coinciding with interpreted shear zones and spatially associated with the highest tenor Au-Cu-Mo anomalism. These elevated chargeability zones align with areas of pronounced structural complexity, including NE-fault intersections and major flexures within the shear corridor.

Section 1 Sampling Techniques and Data

Criteria	JORC Code explanation		Commentary
Sampling techniques	• Nature and quality of sampling (eg cut channels, random chips, or specific specialised industry standard measurement tools appropriate to the minerals under investigation, such as down hole gamma sondes, or handheld XRF instruments, etc). These examples should not be taken as limiting the broad meaning of sampling. • Include reference to measures taken to ensure sample representivity and the appropriate calibration of any measurement tools or systems used. • Aspects of the determination of mineralisation that are Material to the Public Report. • In cases where ‘industry standard’ work has been done this would be relatively simple (eg ‘reverse circulation drilling was used to obtain 1 m samples from which 3 kg was pulverised to produce a 30 g charge for fire assay’). 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.		GML – IP Survey • Survey consisted of a grid, Double offset Pole Dipole IP (PDIP) with 100m dipole spacing with 100m Transmitter dipoles, 100m moves. • Equipment included a Search 50kVA transmitter and SMARTem 24 channel receivers. • N level is 16 channels. • Square Waveform - 0.125Hz (2 second on, 2 second off time base) • Receiver survey lines were 300m apart, with TX lines 600m apart with 100m dipole spacing for both transmitter and receiver. Newcrest • Vertical RAB drilling conducted with sampling every 2m until refusal or hole failing in palaeochannels. • Samples were collected using a spear from sample piles. • Drilling was conducted on an initial 4.5km x 400m grid and later infilled to 1.5km x 400m. Eagle Mining • Eagle Mining operated in the Horse Well Project between 1993 and 1997. • RAB drilling was undertaken by Kennedy Drilling Pty Ltd using a custom built RAB rig using 600 CFM and 300PSI. • Samples were submitted to AAL in Kalgoorlie for analysis of Au using a single stage and grind preparation with an aqua regia digest and an AAS finish to a detection limit of 0.02ppm Au.

			• Aircore drilling was completed by Raglan Drilling and were completed to blade refusal, usually at saprock or fresh bedrock to an average depth of 66 metres. • This reconnaissance drilling was carried out a widely spaced pattern of 200 metres by 400 metres, with drill samples composited over 4 metre intervals and assays for gold down to 0.001ppm or 1ppb Au. Any gold values greater than 0.05ppm Au in the 4-metre composite were considered significant to warrant follow up drilling. • Drilling samples were transported by trailer to Wiluna, where they were placed in bulky bags and shipped to Perth via Toll-Ipec for assay. The drilling samples were analysed by ALS-Chemex in Perth. All samples and blind standards were analysed for gold using 30g fire assay and ICP-AES finish (range 0.001-10ppm Au). Assays greater than 10ppm were analysed using the AA25 methos, but only standard samples were above this level. • The initial RC program at Warmblood was carried out by Easternwell Drilling. RC samples were split directly from the cyclone into 2kg bags for every metre drilled. Samples were assayed as 4 metre composites. For all 4 metre composite samples which returned greater than 0.5g/t Au, 1 metre samples were collected from the original ‘split’ one metre samples and assayed. Alloy Resources & Doray Minerals Ltd (JV) From 2013 to 2021 exploration work was undertaken by Alloy Resources and Doray Minerals Ltd under the pre-existing JV agreement. The details regarding RC sampling from this work is outlined below: • Reverse circulation (RC) percussion drill chips collected through a cyclone and cone splitter at 1m intervals. • Spitter was cleaned regularly during drilling. • Splitter was cleaned and levelled at the end of each hole. • Mineralisation determined qualitatively through rock type, sulphide and quartz content and intensity of alteration.

	• Whether sample sizes are appropriate to the grain size of the material being sampled.		• Samples were submitted to AAL in Kalgoorlie for analysis of Au using a single stage and grind preparation with an aqua regia digest and an AAS finish to a detection limit of 0.02ppm Au. No multi element analysis was undertaken during this time. Alloy Resources • RC chips were cone split every metre, sampled dry where possible and wet when excess ground water could not be prevented. Sample condition (wet, dry or damp) was recorded at the time of logging. • Where mineralisation was unlikely in RC holes, the samples were composited by spear sampling – four x 1 metre subsamples combined to approximately 3kg and submitted for assay. • For AC drilling, 1m samples were sub-sampled using a spear and composited into a 4m sample and submitted for assay. Samples that returned anomalous results were subsequently re-sampled at 1m intervals using a spear. • No details exist regarding rock chip sample QAQC practises.
Quality of assay data and laboratory tests	• The nature, quality and appropriateness of the assaying and laboratory procedures used and whether the technique is considered partial or total. • For geophysical tools, spectrometers, handheld XRF instruments, etc, the parameters used in determining the analysis including instrument make and model, reading times, calibrations factors applied and their derivation, etc. • Nature of quality control procedures adopted (eg standards, blanks, duplicates, external laboratory checks) and whether acceptable levels of accuracy (ie lack of bias) and precision have been established.		Newcrest • Samples were analysed at AAL, Perth by Au-BLEG and Pd-BLEG achieving detection limits of 0.1ppm and 0.01ppm, respectively. • The internal laboratory precision is noted as 10%. Eagle Mining • The majority of samples were analysed using Aqua Regia which is a partial analysis. • No information was recorded regarding QAQC or sampling practices at this time. Alloy Resources • Fire assay was used and is a total digest technique for RC samples, and a mix of Fire Assay and Aqua Regia was used for aircore samples and rock chip samples.

			• Certified reference material standards were inserted at 1 in every 50 samples. • Lab: Random pulp duplicates were taken on average 1 in every 10 samples. • Accuracy and precision levels have been determined to be satisfactory after analysis of these QAQC samples. • Quality control procedures are not outlined in WAMEX archive reports for rock chip samples.
Verification of sampling and assaying	• The verification of significant intersections by either independent or alternative company personnel. • The use of twinned holes. • Documentation of primary data, data entry procedures, data verification, data storage (physical and electronic) protocols. • Discuss any adjustment to assay data.		Newcrest • Data is present in hardcopy files from AAL and scanned paper maps showing drillhole locations. Eagle Mining • Logging and sampling were recorded on paper logs. Alloy Resources transferred these logs to digital format and loaded them into the corporate database. Alloy Resources • All sampling was routinely inspected by senior geological staff. Significant intercepts were inspected by senior geological staff. • Data was hard keyed into Excel data capture software and merged with Datashed SQL based database on Strickland’s internal company server. Data is validated by a Database Administrator, import validation protocols in place. • Visual checks of data were completed within Surpac software by consultant geologists.
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.

			• Drill collar coordinates are handwritten on paper logs and plotted on topographic maps in a local grid. Eagle Mining • The grid system used was MGA94 Zone 51. Historic holes were surveyed by DGPS or handheld GPS by Strickland Metals. • Topography was built using collar surveys surveyed by DGPS. Alloy Resources • Collars and rock chip samples: surveyed with GPS with expected relative accuracy of approximately 2-3m. • Downhole: surveyed with in-rod reflex Gyro tool continuously. • Holes are located in MGA94 zone 51. • Estimated RL’s were assigned during the drilling.
Data spacing and distribution	• Data spacing for reporting of Exploration Results. • 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.		GML – IP Survey • Survey lines were 300m apart, with survey points on lines were 100m apart. Receiver survey lines were 300m apart, with TX lines 600m apart with 100m dipole spacing for both transmitter and receiver Eagle Mining/Newcrest • The majority of the historic vertical RAB drilling completed by Eagle Mining were on wide spaced 200m x 200m spacings (Eagle Mining) and 1.5km x 400m spacing (Newcrest). This style of drilling, coupled with the partial aqua regia/BLEG assay analysis and wide spaced drill collar spacings indicate that this is not adequate for any mineral resource reporting. Alloy Resources • AC drilling was completed at 400mNW x 200mNE spacing and infilled to 200m x 200m spacing, where mineralisation was intercepted at Mustang.

			• One fence line of RC drilling as completed at Mustang on 100m spacing, drilling -60 degrees to the SE. No lateral continuity of mineralisation has been determined. • Rock chip samples were collected at each outcrop as deemed necessary by the geologist. No nominal sample spacing was used for rock chip sampling.
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.		GML – IP Survey • The orientation of the IP geophysical survey is appropriate for the structural and geological trends observed in both the ground gravity and aeromagnetic datasets. Historic Drilling • RAB and Vacuum drilling were conducted vertically to a shallow depth, which is deemed reasonable given the horizontal nature of transported cover and supergene mineralisation. Drilling did not penetrate in-situ fresh material, thus structural orientation is not deemed relevant for shallow holes.
Sample security	• The measures taken to ensure sample security.		GML – IP Survey • Data was collected by Moombarriga Geoscience in the field and sent to Terra Resources directly for processing. Newcrest • No details exist. Eagle Mining • The data was originally maintained by Eagle Mining Corporation and forwarded to Normandy Jundee Operation. Alloy Resources • Alloy Resources' historic samples sent to the laboratory by Company personnel. • The database and Chain of Custody of sample data was managed by a dedicated Company employee.

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. • The assumptions used for any reporting of metal equivalent values should be clearly stated.	Historic Drilling • No top-cuts have been applied when reporting results. • No metal equivalent values were used for reporting of exploration results. • No aggregate results are shown in this announcement.
Relationship between mineralisation widths and	• 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.	Historic Drilling • The wide-spaced nature of the historic vertical RAB drilling along the Mustang and Nabberu Shear Zones are too wide spaced and shallow to determine the structural orientation of these features.
