Figure 1: Gordons Project location in context to Horizon Minerals tenement holdings, regional geology and surrounding infrastructure The Company is focussed on becoming a standalone gold producer by refurbishing and repurposing the Black Swan processing plant into a gold plant with a nominal throughput of 1.5Mtpa. Horizon is undertaking a Pre-Feasibility Study (PFS) to develop a five-year life of mine plan to feed the plant. This acquisition is very close to Black Swan and complements the Company’s existing extensive tenement portfolio. Project Summary The Gordons Project area comprises of 34 granted mining, prospecting and exploration licences covering a mostly contiguous area of approximately 77 km as well as four pending mining and miscellaneous licenses (Figures 1 and 2). A complete list of the tenements in Appendix E Table 2. The Project is located within a prospective Archean Greenstone sequence of lithologies which also Page 2 of 69 ASX ANNOUNCEMENT hosts the Mulgarrie and Gordon Sirdar Gold Mines (Figure 2). Several gold prospects and targets at various stages of exploration and development as well as the Gordons Dam Deposit comprise the Gordons Project (Figure 3). Horizon Minerals is of the opinion that there is potential to identify extensions to mineralisation across numerous gold targets and prospects. Project History No economic scale historical mining activities within the Gordons Project exist however there is evidence of mining activities such as shafts dating back to 1901. Prior to the Gordons Project and underlying area being acquired by Yandal Resources in 2018, extensive exploration activities occurred by multiple companies and parties (refer Appendix B JORC Table 1, Project Gordons Dam – Exploration, Section 2). Historical drillholes (drilling activities undertaken prior 2018 and Yandal Resources ownership) as well as drilling conducted by Yandal Resources are identified in figures 2 and 3 as well as Table 1 (Appendix D) and Figure 1 (Appendix E) of this announcement. Drill collars represented as maximum downhole assays (ppm). The historical drillhole data was compiled originally by Yandal Resources from open file WAMEX reports, then reviewed and validated by Horizon Minerals. WAMEX open file reports that include historical drillhole data include A037661, A044420, A048153, A051519, A057836, A059314, A60036, A60913, A064353 and A06613. Hole location and drilling type for all previous drilling within the entire project area are highlighted in Figure 1 of Appendix E in this Announcement. Numerous significant intercepts from drilling activities undertaken by Yandal Resources have been identified within the database with better intercepts identified in Table 1 (Appendix E). Significant intercepts determined on samples returning a gold assay value >1.0 ppm Au over an interval of greater than 2m without the inclusion of internal material of < 1.0 ppm Au. Project Geology The Gordon’s Project contains tenements covering an area within the Boorara Domain of the Kalgoorlie Terrane, part of the larger Norseman-Wiluna Archean Greenstone Belt bounded by the Bardoc Shear Zone to the west and the Mount Monger Fault to the east. The geology of the Project is dominated by a sequence of mafic, ultramafic and felsic rocks with numerous porphyry intrusions thrust against the large granite body of the Scotia-Kanowna Granite to the west. The major structural feature of the Project is the Gordon Sirdar Shear Zone (GSSZ) that extends throughout the entire area and is interpreted as being coincident with a number of gold prospects as well as the gold deposits of Gordon Sirdar and Mulgarrie. The GSSZ and related splays is interpreted to be associated with the steepening of the eastern margin of the Scotia-Kanowna Granite and is a key feature to investigate for further gold prospectivity.

Page 5 of 69 ASX ANNOUNCEMENT Mineral Resource Estimate (MRE) Located within the Gordons Dam project area is the Gordons Dam deposit which has a MRE of 365,000t @ 1.7g/t Au for 20,000oz (> 1g/t Au lower cut-off grade) (Figure 3). The Gordon’s Dam deposit includes mineralisation hosted within laterite, transported cover sediments (paleochannel material) and weathered and fresh bedrock. Primary mineralisation occurs in quartz veins that occur at the margins of pillow basalts intruded by later microgranite/porphyrys. Mineralisation within the MRE extends from approximately 30m below surface to a current maximum depth of 120m. Zones of mineralisation are associated with a laterally extensive paleochannel at the base of oxidation and at depth into the fresh bedrock with an overall mineralised north-west trend of approximately 320m in strike length. Further detailed information on the Gordons Dam MRE is presented in the Technical Overview section of this announcement. Acquisition Key Terms The Company has executed a binding Tenement Sale Agreement (“TSA”) to acquire the project areas from Yandal Resources Limited, for a total consideration of A$2.810m. The A$0.2m refundable cash deposit already been paid, with deferred consideration of A$1.0m in cash and $1.610m in Horizon shares payable at settlement with the shares to be issued at an issue price equal to a 10% discount to the 15 trading day volume weighted average price up to and including the day immediately prior to the date of execution of the TSA The consideration will be funded from existing cash reserves and placement capacity. Conditions precedent to settlement include: • Regulatory approvals typical of a transaction of this nature • Consent of the Minister required under the Mining Act for the transfer of the tenements having been obtained • The execution of any third-party agreements required • The provision of all mining information Settlement of the transaction is expected in the current September quarter 2025. Page 6 of 69 ASX ANNOUNCEMENT Appendix 1 – Material Information Summary (Listing Rule 5.8.1) Technical Overview – information required by Listing Rule 5.8.1 Pursuant to ASX listing rule 5.8.1, and in addition to the information contained in the attached JORC Code tables, the Company provides the following details in respect of the Gordons Dam MRE. Material Information Summary – Mineral Resources Location The Gordons Project is located on Mt Vetters pastoral station approximately 45km northeast of Kalgoorlie- Boulder. The project is 15km north of the Kanowna Bell Gold Mine and surrounds the Gordon-Sirdar Gold Mine. Access is via Yarri Road to Kanowna, then approximately 5 kms north on the Mulgarrie-Kanowna Gazetted Road. Numerous prospector and historical mine tracks cross the area provide excellent access to most areas of the project. Regional Geology The Gordons project lies within the Boorara domain of the Kalgoorlie Terrane, part of the broader Norseman-Wiluna Archaean greenstone belt. The Norseman-Wiluna greenstone belt is approximately 600 km long and is characterised by very thick, possibly rift-controlled accumulations of ultramafic, mafic and felsic volcanics, intrusive and sedimentary rocks. The Kalgoorlie Terrane of the south-eastern Goldfields has since been formally subdivided into numerous tectono-stratigraphic domains. These include four major domains, Coolgardie, Ora Banda, Kambalda and the Boorara Domain. The Boorara domain, bounded by the Bardoc Shear Zone to the west and the Mount Monger Fault to the east, is interpreted as the easternmost portion of the Kalgoorlie Terrane. This terrane is regarded as an originally coherent volcano-sedimentary basin formed between 2.72 Ga and 2.68 Ga and is characterised by a regional lithostratigraphy; a lower tholeiitic basalt, komatiite, upper highMg basalt and a composite felsic unit. In the Boorara domain, the Gordon project area contains a lower pillowed basalt unit overlain by large homogenous dacite and komatiite intercalations, the uppermost komatiite unit is overlain by an extrusive basaltic sequence. These units generally trend north- east, and prominent shear zones strike to the north-west. The Gordons tenements lie on the eastern limb of the Scotia Kanowna Dome. Deposit Geology and Mineralisation Primary mineralisation at the Gordons Dam deposit is hosted within pillow basalts (observed from drill core) and a discordant felsic intrusive that dips moderately to the north-east. Gold mineralisation transects the felsic intrusive. The intrusion has a probable rheological control on mineralisation with gold being deposited preferentially where the mineralising structure(s) interact with the intrusion. The dominant structural fabric is controlled by a series of discontinuous faults and weak shear zones with an overall trend to the north-north-west. A second structural feature in the area is a “kink” zone Page 7 of 69 ASX ANNOUNCEMENT defined by a 400m wide zone nearer to north-trending, very open Z-style folding in the stratigraphy. Gordons Dam is hosted within the interplay of this kink zone and the dominant north-north-west trend. There are multiple generations of veining at Gordons Dam, with both quartz dominant, quartzcarbonate +/- sulphides and carbonate plus sulphide veins observed in chips and diamond core. Current observations suggest that only the quartz dominant veining is associated with gold mineralisation. These veins are quartz rich (grey and cloudy), with minor carbonate and pyrite as thin selvages and rarer disseminations. Chalcopyrite has been noted in polished thin sections. Narrow alteration halos develop around the veining dominated by sericite, chlorite, silica and minor pyrite. Mineral Resource Statement Overview The Gordons Dam mineral resource was completed by Yandal Resources. Horizon Minerals has conducted a detailed review and audit of the Mineral Resource Estimate and confirms the veracity of the MRE. BM Geological Services (BMGS) were engaged by Yandal Resources to complete a Mineral Resource Estimate (MRE) for the Gordons Dam deposit situated 45 kilometres northeast of Kalgoorlie-Boulder, during November 2022. The MRE is based on recent and historical reverse circulation (RC) and diamond (DH) drill hole data. The MRE utilised four diamond (DDH) and 91 Reverse Circulation (RC) drill holes to create3dimensional (3D) mineralisation wireframes and weathering surfaces. The interpretation was then used to flag drilling data to be used in the estimation of gold grades into a block model constructed using the Geovia Surpac software package (Surpac). The mineralisation interpretation was completed on 20 metre spaced drill sections, using a nominal 0.5 g/t Au lower cut-off. The MRE was classified as Inferred based on drill density, geological understanding, grade continuity and economic parameters of Open Pit mining. The MRE contains 365,000 tonnes at 1.7 g/t Au for 20,000 ounces of gold using a 1.0 g/t gold lower reporting cut-off (Table 1). Results were originally announced by Yandal Resources in April 2023. 3 Table 1 - Gordons Dam Mineral Resource Estimate (1.0g/t Au Lower Grade Cut-off) above 136m vertical depth. Category Tonnes Grade (g/t Au) Total Ounces Inferred 365,000 1.7 20,000 Note: Due to the effects of rounding, totals may not represent the sum of all individual components Drilling, Sampling and QA/QC The drilling database used to compile the MRE comprised 95 drill holes. A summary of hole types used in the estimation process are listed in Table 2. Figure 4 indicates the location of the drillholes 3 As announced to the ASX by Yandal Resources on 6 April 2023. Page 8 of 69 ASX ANNOUNCEMENT used to compile the MRE as well as the location of other previous drillhole collars and types within the immediate area.

Page 9 of 69 ASX ANNOUNCEMENT The QAQC process for monitoring the sampling and assaying included: • • • • • • Collection of 4 m composites using a PVC spear and 1 m samples through a rig mounted cone splitter. The inspection of drill samples to check recovery, moisture, and contamination. The assaying of samples using the fire assay method. The inclusion of certified reference standards (standards) for a range of gold grades to test the accuracy of the laboratory. The inclusion of fine blanks to test for contamination at the sample preparation stage and the assaying stage. The collection of field duplicate samples by collecting 2 samples at the same time from the cone splitter to test the repeatability of the samples. RC Samples were returned through a hose into a cyclone which then emptied its contents into an RC bag. At the time of drilling, 1 m splits were taken using a riffle splitter then a 4 m composite was collected using a 450 mm by 50 mm PVC spear-tube. If an anomalous gold grade was return (>0.1 g/t) from the composite sample, the four single metre splits were submitted for assaying. All RC samples were visually checked for recovery and moisture content. No issues were reported with sample recoveries. All samples were assayed using 50 g charge lead collection Fire Assay. Eleven different standards (certified reference material - CRM) representing the range of grades expected at Gordons Dam were submitted with samples sent to the laboratory. Standards were inserted at an average rate of 1 in every 20 samples collected. Duplicates were collected at a nominal rate of 1 in every 33 samples resulting in 384 duplicate pairs. Hole collar locations have been confirmed and updated by field personnel checking locations on site. All drill holes use the MGA Zone 51 Datum GDA 94. All holes used either a gyro or digital downhole camera at 30 m intervals for downhole survey orientations. All RC and DD holes have been geologically logged; the data was then entered into a Microsoft Excel spreadsheets and imported into a Microsoft Access database. Estimation Methodology The model was estimated using both Ordinary Kriging (OK) and Inverse Distance Squared (ID2). Domains were estimated separately using the wireframe as hard boundaries to prevent smearing of grades. Wireframes Mineralisation wireframes were provided to BGMS by the project geologists. The wireframes consist of a stacked series of 26 parallel lodes that have an overall trend striking towards 310° and a 30° dip to the northeast. An additional six domains (27-32) sit in the transported and oxide zone, have various strikes and are flat lying. A nominal cut-off of 0.5 g/t gold was used to define mineralisation boundaries; however, lower grades were sometimes included to maintain continuity. The Page 10 of 69 ASX ANNOUNCEMENT mineralised lodes were flagged to the “domain” attribute in the model. mineralisation wireframes in plane and long section views respectively. Figure 5 shows the Figure 5: Gordons Dam Wireframes: Plan (left), Long-section viewing north-east (top right) Weathering Base of alluvial (BOA), base of complete oxidation (BOCO) and top of fresh rock (TOFR) surfaces were interpreted by the project geologists and are based on the oxidation and lithology logging in the database. Compositing With over 99% of samples being 1.0 m or less in length, 1.0 m was chosen as the compositing length. A composite string file was created in Surpac from all RC and DD drilling. The composite file was passed through each domain wireframe and any composites falling within a wireframe were coded with the domain number. The individual composites were combined into one file representing all mineralisation to be used in statistical evaluation and grade estimations. All samples that fell outside of the wireframe solids were put in another file that represents the background waste material in the deposit. Grade Bias Analysis The dataset was assessed for bias from extreme grades that would require adjustment or top cut. Composite statistics for each lode, where there were sufficient samples for statistical analysis, were reviewed and top cuts were selected based on the coefficient of variation, the max composites value Page 11 of 69 ASX ANNOUNCEMENT and the grade distribution. Domains with limited samples were visually reviewed to ensure high value composites were not having an undue effect on the mean grade. A top cut of 19.5 g/t Au was selected by analysing the spatial characteristics of the dataset using the series of graphs displayed in Figure 6.

Experimental variograms were generated for the lodes with sufficient samples to assess the continuity and allow for generation of a variogram model. To ensure the composited data accurately reflected a normal histogram for Variogram analysis a normal scores transformation was completed. Continuity fans were then used to select the orientations of major and minor continuities. Experimental variograms were generated for these orientations with downhole continuity being utilised to select the nugget and the subsequent directional variograms were fitted with models best matched to the data. The variogram model was back transformed before being exported into a Surpac variogram file to be used in estimation. Variography was attempted on each domain individually, however the small number of composites available did not produce any usable variograms. To increase the number of composites available for analysis variography was carried out on the whole dataset.

Gordons Dam SECTION 1 Sampling Techniques and Data (Criteria in this section apply to all succeeding sections) Criteria JORC Code explanation Commentary Sampling techniques Nature and quality of sampling (e.g. 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. 4m composite samples taken with a sample scoop thrust into the RC sample bag laid out in individual metres in a plastic bag on the ground. 1m single splits taken using a cone splitter at time of drilling, if 4m composites are anomalous (>100200ppb or lower depending on location), 1m single splits are submitted for analyses. The average sample weights for 4m composites is approximately 3.0kg and 3.0-4.0kg for 1m samples. Include reference to measures taken to ensure sample representivity and the appropriate calibration of any measurement tools or systems used. For RC and AC drilling, regular air and manual cleaning of the cyclone to remove hung up clays were
