Announcement PDF ASX Announcement 18th Dec 2025 Antimony Results and ​ Worley Engagement Advancing Processing Pathways ​ Felix Gold Limited (ASX: FXG) is pleased to report additional drilling results from the NW Array antimony-gold prospect at the Treasure Creek Project in the Fairbanks Mining District, Alaska, including 3.04m @ 6.3% Sb. Multiple drill holes confirm the continuity of high-grade stibnite veining exposed in trenching earlier this year, with a shorter parallel footwall vein structure also identified. These and other results support the model of multiple, sub-parallel antimony-bearing vein structures within the mineralised system, adding to the overall mineralisation inventory as the Company advances toward bulk sampling. In addition Worley has been engaged to conduct site smelter site selection and investigate potential fast tracking metal production through toll treatment options. Highlights Antimony Result ●​ Multiple holes confirm continuity of high-grade stibnite vein zone exposed in trench 25NWTR005 ●​ 3.04m @ 6.3% Sb from 36.58m (25TCRC029) ●​ 6.09m @ 2.59% Sb from 21.34m (25TCRC016) ●​ 3.05m @ 3.54% Sb from 15.24m (25TCRC026) ●​ Parallel footwall vein zone identified with grades up to 5.89% Sb over 1.53m ●​ High-grade breccia-style mineralisation intersection of 7.54m @ 2.47% Sb (25TCDC003) ●​ Results support model of multiple stacked vein structures; system remains open ●​ Gold assay results pending for a substantial number of holes; news flow expected through Q1 2026 Worley Engagement ●​ Worley has been engaged to advance U.S. site selection for Felix Gold’s own processing facility while simultaneously assessing potential toll-treatment options, with the objective to create parallel pathways that preserve strategic control and accelerate the timeline to first metal.​ Felix Gold’s Executive Director, Joe Webb, commented: Felix Gold continues to execute rapidly across the full value chain, with technical, permitting, and downstream workstreams advancing in parallel with the objective to accelerate the pathway to first metal while preserving long-term strategic optionality. Engineering and baseline programs have now progressed to a point where downstream processing decisions are transitioning from conceptual assessment to site-selection and execution planning, with Worley engaged to advance U.S. site selection for the Company’s own processing facility while simultaneously assessing potential toll-treatment options. Recent drilling continues to validate and expand the NW Array geological model. Multiple holes have confirmed strong continuity of the high-grade vein zone exposed in trenching, while the identification of parallel footwall zones and broader breccia-hosted mineralisation supports the interpretation of a stacked, corridor-scale system that remains open along strike and at depth. This work is directly increasing the Felix Gold Limited (ASX.FXG)​ ​ 1 ASX Announcement 18th Dec 2025 inventory capable of feeding a U.S. domestic antimony supply chain, with ore supply—rather than processing capacity—representing the true bottleneck to near-term production. The Company is advancing toward near-term production through bulk sampling, with commencement targeted as soon as practicable following receipt of necessary permits and Board approval. Subject to these approvals, the project is positioning with the objective for a transition from bulk sampling into sustained operations. Felix Gold is making rapid, coordinated progress across all critical workstreams as it advances toward first metal, with multiple near-term catalysts spanning drilling results, bulk sampling readiness, metallurgy, downstream processing and permitting. Extensive gold and antimony assays are pending, baseline and engineering programs are well advanced, and metallurgical work continues to confirm the ability to produce military-grade concentrate through simple processing. In parallel, Worley has been engaged to progress U.S. site selection for the Company’s own processing facility while also assessing toll-treatment options, providing parallel pathways to accelerate production while preserving strategic control. Engagement with multiple U.S. federal agencies is intensifying as Felix Gold advances alignment on domestic antimony supply and national-security objectives. Together, these initiatives position the Company as a leading, near-term solution to a critical U.S. military-grade antimony supply-chain gap, while maintaining the commercial flexibility required to maximise long-term value from a scarce, high-grade asset. Further detail on this strategic update is set out below. The production timeline remains subject to completion of appropriate technical studies, permitting approvals, funding, and Board approval.

Felix Gold Limited (ASX.FXG)​ ​ 2 ASX Announcement 18th Dec 2025 Strategic Positioning Central to this approach is Felix Gold’s deliberate focus on military-grade and semiconductor-grade antimony supply chains. While broader consumer-grade antimony markets fluctuate, pricing and demand for high-purity, defence-critical material continue to strengthen, underscoring the strategic value of the Company’s NW Array mineralisation. Entering early sales agreements would constrain commercial flexibility, limit alignment with strategic counterparties, and risk materially undervaluing an asset that is increasingly recognised as strategically scarce. Accordingly, the Company is prioritising pathways that maximise long-term value and preserve commercial optionality. Permitting & Baseline Programs At the project level, Felix Gold is materially de-risking the transition from bulk sampling into sustained operations. All baseline programs required for long-term development are well advanced or complete, including wetlands delineation, air monitoring, surface water and fish habitat studies, waste-rock characterisation, cultural heritage assessments, and groundwater monitoring, with eleven monitoring wells installed across Treasure Creek. In parallel, detailed engineering for on-site mining and processing is progressing, and drafting of the long-term operating permit is well advanced and remains on track for submission in Q1. Together, these activities significantly increase confidence in a seamless progression to continuous operations. Downstream Processing Downstream, Felix Gold is deliberately assessing compressing timelines to first metal. Worley has been engaged to advance site-selection work for the Company’s own U.S.-based processing facility, reflecting the level of engineering maturity now achieved and the strategic importance of retaining long-term control over metal production. In parallel, Worley is also assessing potential toll-treatment options within the United States, providing a secondary pathway that could materially accelerate initial metal production while final site and development decisions are completed. These parallel pathways are complementary, not mutually exclusive, and ensure speed without sacrificing strategic positioning. Material Quality Metallurgical testwork has already confirmed that NW Array material can produce military-grade concentrate through simple, single-stage processing, materially reducing technical and execution risk. As downstream arrangements are finalised, the Company may undertake short-term stockpiling of high-grade material, ensuring ore is immediately available for conversion to metal once processing pathways are locked in. This approach accelerates—rather than delays—the achievement of first production. Government Engagement In parallel, engagement with multiple U.S. federal agencies continues to intensify as the strategic importance of secure, domestic antimony supply becomes increasingly recognised. Discussions are focused on near-term production, downstream processing pathways, and alignment with U.S. critical-minerals and national-security objectives. This engagement reinforces the Company’s decision to preserve strategic optionality and maintain flexibility in potential commercial and development structures as it advances toward first metal. Felix Gold Limited (ASX.FXG)​ ​ 3 ASX Announcement 18th Dec 2025 Treasure Creek Project Overview The Treasure Creek Project is located in the Fairbanks Mining District, Alaska, approximately 30km north of Fairbanks and 20 minutes from Felix's operational base. The Fairbanks Gold Mining District has produced over 16 million ounces of gold historically and hosts Kinross Gold's Fort Knox mine, a Tier 1 operation. Felix is the largest landholder in the Fairbanks Mining District. The district's existing infrastructure—power, roads, skilled workforce and proximity to processing facilities—offers a straightforward development pathway for both gold and antimony. ​ Fig 1. Location of NW Array within Treasure Creek with near-term antimony production focus Felix Gold Limited (ASX.FXG)​ ​ 4 ASX Announcement 18th Dec 2025 NW Array Prospect The NW Array Prospect hosts both high-grade antimony and gold mineralisation within the same structural corridor. Gold generally forms a broader mineralisation halo within and around antimony-bearing structures. The prospect includes the historic Scrafford Mine, Alaska's second-largest historical antimony producer with recorded production grades up to 58% Sb. Felix's exploration in early 2025 discovered a 25-metre-long stibnite vein near surface with intersections including 3m @ 50.26% Sb (true width). Systematic drilling has now defined additional veining and extended mineralisation over an area approximately 200 metres by 125 metres to depths exceeding 150 metres vertically, with the system remaining open along strike and at depth. Gold assay results from the 2025 drilling program remain pending, with continued news flow expected through Q1 2026. Key Project Attributes ●​ Location: Alaska, USA – stable jurisdiction with established mining history ●​ Infrastructure: 20 minutes from Fairbanks with year-round road access, grid power, and a skilled workforce ●​ Mineralisation: High-grade stibnite with simple mineralogy (predominantly Sb₂S₃) ●​ Timeline: Objective is to commencement prior to or early in 2026 for initial production from bulk sampling ●​ Permits: Bulk sample permit amendment lodged; multi-year permit targeting Q1 2026 submission ●​ Strategic Context: Domestic US antimony supply for defence and industrial applications Drilling Results - NW Array 2025 Program Program Overview An extensive program of drilling at the NW Array gold-antimony prospect has recently been completed. To date a total of 56 RC holes for 3,077 m (including 9 water monitoring bores) and 67 diamond holes for 5,858.65 m have been completed. Drilling is targeted at better defining the extents and grade of high-grade antimony and gold mineralisation intersected in previous drilling and trenching campaigns. Samples from the drilling program have been submitted to MSA Laboratories in Vancouver for multi-element analysis with specialised methods for high-grade antimony and PhotonAssay for gold. Multi-element and antimony assays are pending for 10 RC holes and 51 diamond holes, with gold assay results pending for 49 RC holes and 58 diamond holes. Results Antimony assay results have been received for 11 RC holes, 2 diamond holes and 1 trench. Collar details are presented in Table 2 with significant intersections (above a cut-off of 0.2% Sb) summarised in Table 3 . A map of and cross section of results are presented in Fig 2 and Fig 3 respectively. Felix Gold Limited (ASX.FXG)​ ​ 5 ASX Announcement 18th Dec 2025 Main Vein Zone – Trench 25NWTR005 Correlation Drill holes 25TCRC025, 026, 029 and 030 all intersected the east-west trending and south dipping zone of stibnite veining exposed in trench 25NWTR005, returning grades between 0.58% and 6.3% Sb over downhole widths of 3.0m to 4.5m (estimated true widths between 0.65m and 3.2m). A less continuous but parallel zone of stibnite veining was intersected in the footwall of this main zone, with grades between 0.67% and 5.9% Sb over downhole widths between 1.5m and 3.0m. Although 25TCRC048 should also pass through this veining zone, the highest-grade sample within the corresponding part of the drill hole is only 0.1% Sb. Northeast Vein Zone Holes 25TCRC016 and 017 intersected another east-west striking vein some 40m northeast of trench 005 with grades of 2.58% and 1.58% over downhole widths between 3m and 6m respectively. These are correlated with similar grades in previously reported holes in the same structure. Southern Vein Zone Hole 25TCRC015 intersected high Sb grades within a WNW striking vein zone to the south of 25NWTR005, consistent with several other RC and diamond core holes in the same area. Northern Area The wider intersection in hole 25TCRC003 of 16.76m @ 0.95% Sb is located at the northern end of the current drilling area where the geological interpretation is uncertain at this time. Diamond core holes here intersect zones of intense brecciation and faulting but the orientations of the structures are unclear. Work is ongoing to better understand this area. Other Results Intersections within the upper 10m of 25TCRC004 and 25TCDC011 are related to other east-west to northeast-southwest trending vein zones. Antimony mineralisation in the upper part of 25TCDC003 is within a fault breccia, although the orientation of the structure is unclear. High grades in the lower part of 25TCDC003 are also within breccia, which is identical in appearance to the 'black breccia' in 25TCDC004 and other holes in the same area. Hole 25TCDC011 is interpreted to have drilled down the hangingwall contact of this breccia zone, but without intersecting any of the high-grade material. A narrow stibnite vein striking 112° was mapped in the western end of trench 25NWTR003 corresponds with a sample of 2.56% Sb over one metre. Eastern Extension Testing Hole 25TCRC024 was one of three holes (022 and 023) drilled testing the easterly extensions to vein zones. No antimony mineralisation was intersected.

Previously reported antimony intersections are coloured by average Sb grade. Note that indicated vein zones and the general trend of intersections may not align due to the oblique angles between the section line, drill holes and vein zones. Antimony Context The 2025 drilling program at Treasure Creek was designed to test high-grade antimony and bulk gold mineralisation at the NW Array prospect. Results from this program, announced through October and November 2025, include: ●​ 3m @ 50.26% Sb (true width) at surface from trenching ●​ 17.78m @ 3.17% Sb including 6.7m @ 5.3% Sb from drilling ●​ 6.1m @ 7.86% Sb from 39.62m in high-grade vein In November 2025, mineralogical analysis of high-grade trench samples showed 89.2% of the in-situ material was antimony-bearing minerals with low levels of impurities—a geological rarity. Multiple processing pathways were validated, including production of a concentrate grading 74% Sb (exceeding US military specification) by standard flotation and extraction of 98% of contained antimony metal via direct alkaline leach - electrowining. The metallurgical program identified separate gold recovery from antimony concentrates and tailings as a priority for future testwork. Maximising gold payability via gravity separation or hydrometallurgical extraction prior to concentrate sale will be a key economic driver given the high gold grades observed.

Felix Gold Limited (ASX.FXG)​ ​ 12 ASX Announcement 18th Dec 2025 APPENDIX: JORC Code Table 1 Report Section 1: Sampling Techniques and Data Criteria 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 downhole 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 drilling was sampled on 1.52 m (5 feet) intervals from which 2-3kg was split and pulverised / crushed to produce samples for ICP multi-element analysis, high grade Sb analysis and gold analysis by PhotonAssay™ ●​ Diamond drill core was sampled over downhole lengths between 0.3m and 2.5m (average 1m) to produce samples for ICP multi-element analysis, high grade Sb analysis and gold analysis by PhotonAssay™ . Diamond drill-core sample intervals were based on changes in geology. ●​ Trenches were excavated using a mechanical excavator to a depth of 1.5 metres. Samples were collected by chipping the exposed area along the trench face with a geological hammer. Polyweave bags were placed under the sampling interval to collect sample debris and to avoid contamination with other material. Samples were generally taken as 1 metre composites 0.75m above the floor of the trench with some smaller composites where the geologist identified different rock types. Total sample weights were generally around 1-2 kg. Felix Gold Limited (ASX.FXG)​ ​ 13 ASX Announcement 18th Dec 2025 Criteria Explanation Commentary 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). ●​ Reverse Circulation (RC) holes were drilled with a 76mm (3 inch) face-sampling hammer with 73mm (2.875 inch) drill rods and 102mm (4 inch) casing. ●​ Diamond holes were wireline HQ (63.5mm diameter) holes. ●​ The diamond drill program reported here was undertaken by C-n-C Drilling LLC utilizing CS 14 skid mounted drill. ●​ Core was oriented wherever possible for collection of structural data using a Reflex ACTIII ●​ The core was reconstructed into continuous runs on a cradle for orientation marking before it was laid in the box at the drill. 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. ●​ RC samples were visually assessed for recovery and were considered representative of bedrock intersected. ●​ Visual inspection of samples estimated no significant loss of sample from each 1.52m interval. ●​ No relationship between sample recovery and reported analyses has been established. ●​ Diamond core recovery was determined by measuring the total length of core in the barrel over the run length. ●​ Hole depths were checked against the drillers core blocks at the time of processing. Inconsistencies between the logging and the driller’s depth measurement blocks were investigated. ●​ Diamond core samples are considered dry. The recovery and condition are recorded between every core block. Generally, recovery is 98-100% but on very rare occasions in weathered material or very broken material, recovery was down to 50%. ●​ For Diamond drilling, contractors adjust the rate of drilling and method of recovery issues arise ●​ No significant sample loss or bias has been noticed Felix Gold Limited (ASX.FXG)​ ​ 14 ASX Announcement 18th Dec 2025 Criteria Explanation Commentary 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. ●​ Qualitative logging of RC chips and diamond core for lithology and alteration with semi-quantitative logs for oxide and sulphide mineralisation. ●​ RC and diamond holes were logged in for their entire lengths. ●​
