Final assay results for Reverse Circulation (RC) drilling completed at six prospects including Swift, Eagle, Goldfinch, Shrike South, Thornbill West and Vigilant have been received (Figure 1). Significant results are outlined below. Figure 1: Gum Creek Gold Project existing Mineral Resources, Potential Mineral Resources and Exploration Targets over simplified geology. Managing Director Scott Williamson said: “These impressive high-grade RC drilling results from Swift, Eagle, Shrike South and Goldfinch continue to unlock our free-milling open pit mining strategy. We’re consistently adding shallow, high- grade resource ounces less than two kilometres from the proposed 2.4Mtpa processing plant while simultaneously drilling deeper to unlock the underground potential throughout the Gum Creek Greenstone Belt. Eagle, Shrike South and Goldfinch have all delivered consistent high grades, with resource estimation underway to define material expansions to the Eagle MRE and maiden MREs for Shrike South and Goldfinch. Importantly, these resource additions sit outside the current Feasibility Study, positioning us for a meaningful uplift to project economics over the coming months. 3 The Feasibility Study remains on track for mid-year completion, with further results expected in the coming weeks as resource expansion drilling continues.” Swift Prospect The Swift Prospect is located 1.2km east of the historic Gidgee mill (Figure 1). The current Swan/Swift open cut MRE is 7.00Mt @ 1.85g/t Au for 415,600oz, and the Swift underground MRE is 0.85Mt @ 2.52g/t Au for 68,800oz (Table A). The Company completed twelve RC holes at Swift for a total of 1,974m including three 120m deep pre-collars for diamond drilling (Figure 2). The program aimed to test for down dip and up-dip extensions to high-grade mineralisation outside of the current Swift resource block model. The Swift Prospect RC drilling returned the following significant intercepts (Figure 3 & Table B):  6m @ 5.13g/t Au from 95m including 2m @ 14.7g/t Au from 98m (SFRC002)  5m @ 4.28g/t Au from 146m including 2m @ 10.28g/t Au from 146m (SFRC013)  3m @ 6.13g/t Au from 123m including 1m @ 17.6g/t Au from 123m (SFRC012)  9m @ 1.10g/t Au from 152m (SFRC012)  8m @ 1.09g/t Au from 145m (SFRC011) Figure 2: Swift and Vigilant drill hole plan showing $2900/oz optimised pit shell outline (white dashes), recent drill holes and recent gold intercepts >8 GxM over satellite image. 4 Figure 3: Swift cross section showing recent RC drill intercept, interpreted mineralised envelopes, previous drill intercepts (>40 GxM) & Swift open pit. The high-grade intercept returned from SFRC002 is located 40m down dip of previous drilling and requires up-dip infill, and down dip and along strike extension drilling. The high-grade intercepts returned from SFRC012 and SFRC013 support the impressive 2021 result of 15m @ 4.0g/t Au from 145m in SWRC006. Crucially, these results confirm the interpreted flat lying, stacked lode model to the west of the main Swift lode (Figure 3)1 .Follow up drilling will also be required to the east of these intercepts. Diamond core extensions to three RC pre-collars (SWRC005-007D) aim to extend to the main Swift lode down dip to the east and provide important structural information about potential controls on the high-grade plunging gold shoots. These holes will be completed in the coming months prior to an MRE upgrade for Swift later in 2026. Eagle Prospect The Eagle Prospect is located 1.2km southeast of the historic Gidgee mill (Figure 1). The current MRE for Eagle is 2.02Mt @ 1.28g/t Au for 83,400oz (Table A). The Company completed 33 RC holes for 2,590m aimed at testing for shallow open pittable mineralisation along strike of the existing resource (Figure 4). Significant intercepts (Table C) include:  3m @ 6.62g/t Au from 43m including 1m @ 16.35g/t Au from 43m (EARC057) 1 Refer to Horizon Gold Limited ASX announcement titled “Significant RC Drilling results from Swift, Swan and Eagle Targets” dated 16 June 2021. 5  13m @ 1.50g/t Au from 34m including 6m @ 2.77g/t Au from 34m (EARC038)  8m @ 2.36g/t Au from 58m including 4m @ 4.47g/t Au from 58m (EARC053)  8m @ 1.13g/t Au from 50m including 2m @ 3.09g/t Au from 52m (EARC038)  5m @ 1.90g/t Au from 29m including 2m @ 4.04g/t Au from 29m (EARC057)  14m @ 0.81g/t Au from 55m including 8m @ 1.02g/t Au from 57m (EARC047)  15m @ 0.59g/t Au from 35m including 4m @ 1.15g/t Au from 38m (EARC042)  3m @ 2.85g/t Au from 42m (EARC061)  5m @ 1.57g/t Au from 48m including 1m @ 6.69g/t Au from 48m (EARC058)  3m @ 2.47g/t Au from 34m (EARC035) Gold mineralisation down to about 70m below surface at Eagle is supergene related, with primary mineralisation hosted within steep west dipping quartz-carbonate-pyrite veins within sericite-carbonate altered basalt. The RC program has successfully extended the known gold mineralisation at Eagle for approximately 300m to the south of the current block model. Wireframing is underway in advance of completing an update to the Eagle MRE. Figure 4: Eagle / Goldfinch drill hole plan showing recent recent gold intercepts >6 GxM over satellite image. 6 Figure 5: Eagle cross section showing interpreted mineralised zones and significant 2026 RC intercepts (>3 GxM). Goldfinch Prospect The Goldfinch Prospect is located 2.0km southeast of the Gidgee Mill. There is no MRE for this prospect. Two RC holes including one re-entry / extension hole were completed for 170m, as follow up to the RC program completed late in 2025. Significant assay results were returned from both holes (Figure 6 & Table D) including:  4m @ 6.19g/t Au from 75m to EOH (GFRC032)  3m @ 5.11g/t Au from 73m (GFRC030) Gold mineralisation at Goldfinch down to approximately 40m below surface is supergene in origin. Below this depth primary mineralisation is hosted within moderate, west dipping quartz-sulphide veins within sericite-carbonate altered basalt (Figure 6). Geological wireframing is currently underway ahead of planned deeper drilling and the estimation of a maiden MRE for the prospect. 7 Figure 6: Goldfinch cross section showing interpreted mineralised zones and significant 2026 and previous RC intercepts. Shrike South Prospect The Shrike South Prospect is located 1.3km southeast of the Gidgee Mill. The Prospect has been mined historically by open cut methods over a total strike length of ~280m. The Prospect is not in the Company’s current project-wide mineral resource estimations. The Company completed twelve RC holes for 1,187m. The drilling aimed to test for shallow strike extensions to gold mineralisation beneath and along strike of the existing pit. Numerous significant intercepts were returned (Figure 7 & Table E) including:  11m @ 1.18g/t Au from 72m including 5m @ 2.20g/t Au from 73m (SSRC011)  7m @ 1.43g/t Au from 82m including 3m @ 2.49g/t Au from 82m (SSRC008)  7m @ 1.33g/t Au from 65m (SSRC004)  7m @ 1.33g/t Au from 68m (SSRC003)  5m @ 1.57g/t Au from 30m (SSRC001)  2m @ 3.91g/t Au from 55m (SSRC002)  7m @ 1.01g/t Au from 72m including 1m @ 4.25g/t Au from 72m (SSRC008)  6m @ 1.00g/t Au from 46m including 1m @ 3.85g/t Au from 50m (SSRC009) 8 Gold mineralisation down to approximately 60m below surface is supergene in origin. Below this depth primary mineralisation is hosted within steep west dipping quartz-sulphide veins within sericite altered basalt. Wireframing is underway in advance of completing a maiden MRE for the prospect. Figure 7: Shrike South & Thornbill West drill hole plan showing recent drill intercepts (>6 GxM) & gram x metre pierce points over satellite image. 9 Figure 8: Shrike South cross section showing interpreted mineralised zone and significant intercepts (>10 GxM). The Thornbill West Prospect is located 1.6km southeast of the Gidgee Mill, where the Company completed an additional three RC holes for 270m. Drilling returned the following significant gold intercepts (Figure 7, Table F):  20m @ 0.65g/t Au from 7m including 3m @ 2.11g/t Au from 22m (THRC012)  10m @ 0.62g/t Au from 11m including 1m @ 3.08g/t Au from 18m (THRC010) Drilling has successfully extended gold mineralisation to the north of the prospect. Further drilling is planned to test for structural continuity and determine if this zone connects with the Shrike South prospect The Vigilant Prospect is located 1.3km east of the Gidgee Mill and forms part of the Swan/Swift open cut and underground MRE. An infill program consisting of three RC holes totalling 311m were drilled to tighten the drill spacing within the current resource. The program returned a best intercept of 2m @ 1.39g/t Au from 130m in hole VIRC010 (Table G). Moving forward, exploration drilling will shift focus toward testing the shallow supergene mineralisation at the southern end of the Vigilant open pit. Feasibility Study Progress The Gum Creek Feasibility Study (FS) is progressing well, risk assessments have been concluded, and a draft FS report nearing completion. The Study remains on schedule for market release mid- 2026. The Company believes the Gum Creek Gold Project will support a robust, commercially viable stand‐ alone mining operation. Sustained strength in the gold price further enhances the economics 10 established in the March 2024 Scoping Study2 and provides a high degree of confidence for the upcoming Feasibility Study outcomes. Preparation work for the Mine Development and Closure Proposal (MDCP) and associated statutory applications is already underway.

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. • Reverse Circulation (RC) drill holes were routinely sampled at 1m intervals down the hole. The upper sections of some holes were sampled at 2m intervals. • Samples were collected at the drill rig using an industry standard rig- mounted cone splitter to collect a nominal 2 - 3 kg sub sample in a numbered calico sample bag, with the remaining sample retained at the drill site for future resampling and/or metallurgical sampling if required. • Routine standard reference material, sample blanks, and sample duplicates were inserted/collected at every 25th sample in the sample sequence. • All RC samples were submitted to Australian Laboratory Services (ALS) in Perth for preparation (including pulverising) to produce a 50g sub-sample for analysis for gold by 50g Fire Assay. Pre-2014 Drillholes • All RC samples were collected at 1m intervals through the drill rig cyclone and then split via riffle and cone splitters. RC samples were typically dry. Composite samples were collected by tube sampling the bulk RC sample bags. • Initially assaying utilised the aqua regia process but most assays used in this report have been by fire assay with an AAS finish using the site laboratory or off-site laboratories. A 50g charge was generally used. • After the year 2000, samples (mainly grade control) were assayed at the accredited on-site laboratory at Gidgee using the Leachwell method. Leachwell cyanide (bottle-roll) assays are apparently more predictive of expected recoveries from Carbon-in-Pulp gold recovery plants, so provide a more realistic grade estimate. Drilling techniques • Drill type (eg core, reverse circulation, open-hole hammer, rotary air blast, auger, Bangka, sonic, etc) and details (eg core diameter, triple or standard tube, depth of diamond tails, face- sampling bit or other type, whether core is oriented and if so, by what method, etc). • All RC holes were completed by reverse circulation (RC) drilling techniques using a DR05 SREPS SR650 drill rig and auxiliary compressor. • Drill rod diameter was 4.5” (114mm) and drill bit diameter was nominally 143mm to 146mm. • A face sampling down hole hammer (5' type 760 SREPS) was used at all times. • All RC drill holes were surveyed for down hole deviation using an Axis Champ Navigator north seeking downhole gyro with downhole readings collected every 5m. Pre-2014 Drillholes • RC drilling was completed with industry standard RC drill rigs using a 4.5” to 5.5” drill bit with either a cross-over sub or a face sampling hammer. 17 Criteria JORC Code explanation Commentary Drill sample recovery • Method of recording and assessing core and chip sample recoveries and results assessed. • Measures taken to maximise sample recovery and ensure representative nature of the samples. • Whether a relationship exists between sample recovery and grade and whether sample bias may have occurred due to preferential loss/gain of fine/coarse material. • A qualitative estimate of sample recovery was done for each RC sample metre collected from the drill rig. • A qualitative estimate of RC sample weight was completed to ensure consistency of sample size and to monitor sample recoveries. • Most RC material was dry when sampled, with damp and wet samples noted in sample sheets and referred to when assays were received. • RC sample recovery and quality is considered to be adequate for the drilling technique employed. Pre-2014 Drillholes • Where documented, RC drilling returned good recoveries, however drill recoveries for some historical holes are not known. • All RC samples were split and mixed in the riffle splitting process. • There is no evidence of there being sample bias due to non- representative or preferential sampling. • No apparent relationships were noted in relation to sample recovery and grade. Logging • Whether core and chip samples have been geologically and geotechnically logged to a level of detail to support appropriate Mineral Resource estimation, mining studies and metallurgical studies. • Whether logging is qualitative or quantitative in nature. Core (or costean, channel, etc) photography. • The total length and percentage of the relevant intersections logged. • All RC drill holes were geologically logged by a qualified Geologist. • Qualitative and quantitative geological logging recorded colour, grain size, weathering, oxidation, lithology, alteration, veining and mineralisation including the abundance of specific minerals, veining, and alteration using an industry standard logging and geological coding system. • A small sample of all RC drill material was retained in chip trays for future reference and validation of geological logging. Pre-2014 Drillholes • All historical drill holes have been logged using the various company logging codes. The type of drill log varies with time depending on drill technique, year and company. • Logging included codes and descri
