2 Horizon Gold Limited (ASX: HRN) ( Horizon or the Company) is focussed on progressing its exploration and development activities at the 100% -owned Gum Creek Gold Project ( Gum Creek or the Project) located in the Mid-West Region of Western Australia (Figure 1). Gum Creek has historically produced more than 1 million ounces of gold and currently hosts a gold resource of 44.45Mt @ 1.50g/t Au for 2.14 million ounces 1. The Project currently covers 524km 2 of granted tenure over the highly prospective and underexplored Gum Creek greenstone belt, which contains 37 open pit and three underground gold mines. During the quarter the Company completed reverse circulation (RC) water bore drilling to obtain essential information for developing a site-wide groundwater model and water balance model as part of the ongoing Gum Creek Feasibility Study. The holes were sampled and assayed for gold due to their proximity to known gold mineralisation and returned numerous significant intercepts. The Company also commenced a strategic partnership with VRIFY Technology Inc. (“VRIFY”), a global leader in AI-assisted mineral exploration. VRIFY will use its proprietary AI-Assisted Mineral Discovery Platform, DORA, to combine VRIFY’s largest proprietary mineral datasets with over 40 years of geological data from Gum Creek to help discover, prioritise and validate high-potential targets and accelerate growth of the existing 2.14 Moz gold resource.

3 Water Bore Drilling Program Results The Company completed 24 vertical water bores (RC holes) for 2,700m at the Eagle, Hawk, Howards, Hyperno-Reliance, Kingfisher, Swan-Swift and Wedge prospects. All holes were geologically logged, sampled, and airlifted with water flows recorded wherever possible. Slotted 50mm casing was inserted into 10 of the most productive holes for water depth monitoring purposes and for sub-terranean fauna survey work. Two old production bores were refurbished (one at Swan and one at Kingfisher) and the most productive hole at Howards was converted into a dewatering bore for water pumping purposes. Pumping test work has now been completed at all Feasibility Study prospects. Apart from providing essential groundwater information for the Feasibility Study, gold assays from the water bore drilling have confirmed historic drilling results, provided valuable continuity of mineralisation information within the tested prospects, and will increase the resource confidence levels within each of the resource models.

9 AI-Assisted Mineral Discovery Platform (DORA) VRIFY have commenced the exploration data integration process, compiling all relevant drilling, geochemical, geophysical, structural, and topographic data into it s proprietary AI-Assisted Mineral Discovery Platform (DORA) for processing and augmentation. By maximising the use of Horizon Gold’s extensive exploration dataset, DORA’s machine-learning models will be able to enhance the extensive geoscientific and geospatial data and create AI-generated 3D prospectivity maps assigning a prospectivity score to each target identified. The software aims to shorten target generation timelines and increase confidence in conceptual drill targeting. Completion of the initial AI prospectivity model over Gum Creek is expected Q4 2025, with an exploration target review and target field validation due Q1 2026 and continuous data addition and target refinement to continue throughout 2026. Feasibility Study Progress and Resource Drilling Work on the Gum Creek Feasibility Study remains on schedule for completion H1 CY 2026, with a draft processing report received, most environmental and Heritage surveys completed, and mine design and water balance modelling all advancing well. Resource expansion RC drilling has been completed at Goldfinch, Robin, Thornbill West and Toucan all located within 3 kilometres of the old Gidgee Mill. All results are awaited. Deep diamond drilling aimed at testing high priority targets down plunge of existing high- grade mineralisation at the Kingfisher and Omega prospects has commenced. The drilling is testing beneath impressive previous drill intercepts including 15m @ 28.5g/t Au from 346m and 10m @ 8.9g/t Au from 190m3 (Kingfisher), and 30m @ 21.1g/t Au from 57m and 13m @ 10.8g/t Au from 122m4 (Omega). Corporate Capital Raising On the 21 July 2025 the Company announced a $12 million capital raising in the form of a private Placement of $5 million to institutional and high net worth investors and 1 for 10 Non-renounceable Entitlement Offer to existing shareholders to raise up to a maximum of $7 million, both capital raising initiatives were undertaken at $0.48 per share. As a result on 29 July 2025 the Company issued 10,320,000 shares in respect to the Placement to raise $4,953,600 (before costs), on 26 August 2025 the Company issued 12,400,670 shares in respect to Non-renounceable Entitlement Offer and on 4 September 2025 the Company issued 2,083,234 shares being the remaining shortfall shares in the Non-renounceable Entitlement Offer (raising a total of $6,952,274 (before costs) in the Non- renounceable Entitlement Offer). The funds from the capital raising have and will be directed towards completion of the Company’s Feasibility Study, further resource exploration drilling, the repayment of debt and general working capital. Funding In April 2025 the Company secured a $2,000,000 short-term loan facility for working capital from Horizon’s major shareholder Zeta Resources Limited. The loan facility was unsecured, with interest 3 Refer to Horizon Gold Limited ASX announcements titled “Diamond drilling returns 15m @ 28.5g/t Au from Kingfisher" dated 12 December 2022 and titled “Outstanding gold intercepts returned from Gum Creek Diamond Drilling” dated 15 March 2022. 4 Refer to Horizon Gold Limited ASX announcement titled “Gum Creek Geological Review” dated 15 February 2021 For personal use only
