Announcement PDF bsite Drilling and Baseline Studies Underway ​ at High-Grade U.S. Antimony Project Felix Gold Limited (ASX: FXG) is pleased to announce that field-based exploration and development activities have commenced at its flagship Treasure Creek Antimony Project in Alaska. The program is designed to generate the data required for a feasibility study into a potential near-term antimony production opportunity. Subject to positive study outcomes and permitting, the company is targeting a development decision that could enable first concentrate production as early as Q4 2025. No results are being reported in this announcement.​ Thursday, 12th June 10am (AEST)​ Join Executive Director of Felix Gold, Joe Webb, for an online investor briefing​ Register here: https://felixgold.investorportal.com.au/investor-briefing ​ Highlights: ●​ Trenching and Drilling Commenced: Trenching and drilling now underway at NW Array and Scrafford prospects to potentially convert existing resources to higher confidence categories and/or expand the current mineral footprint, which will form the basis of development studies. ●​ Baseline Environmental Studies in Progress: Environmental surveys, including surface and groundwater hydrology monitoring, fish studies, and flora and fauna studies are actively being undertaken to support permitting and potential future development. ●​ Engineering and Plant Design: Engineering design work ongoing based on recent exceptional metallurgical test work. ●​ Community and Government Engagement: Ongoing consultation with local communities and commencement of early-stage pre-permitting discussions with state and federal agencies. ​ Felix Gold’s Executive Director, Joe Webb, commented: "Treasure Creek is uniquely positioned — a brownfield site that has already supplied the U.S. government, sitting just outside Fairbanks with road, power, and workforce on its doorstep. We’ve recorded five of the seven highest-grade antimony intercepts ever reported in the S&P Global database, and mineralisation begins right at surface. With record antimony prices and a clear U.S. policy push for secure, domestic supply, we couldn’t be better placed. What we’re doing now is moving with intent — trenching, drilling, environmental and engineering work — to assess the viability of getting this project into production in the near term."

Antimony mineralisation occurs primarily as stibnite (Sb₂S₃) and oxidised forms, including stibiconite and some valentinite, hosted within quartz-mica schists and associated with gold mineralisation. The project benefits from excellent infrastructure access, being located within 20 minutes of Fairbanks, with established roads, power, and a skilled workforce. This proximity to infrastructure significantly de-risks any future development scenarios. ​ ​ Fig. 2 Location of Treasure Creek with near-term antimony production focus Felix Gold Limited (ASX.FXG)​ ​ 3 bsite Fig. 3 NW Array Prospect Trenching with Location of Metallurgical Sample​ ​ ​ This ASX release was approved for release by the Board.​ ENDS Felix Gold Limited (ASX.FXG)​ ​ 4 bsite ​ Enquiries Joseph Webb ​ ​ ​ ​ ​ ​ Reach Markets Executive Director ​ ​ ​ ​ ​ Investor and Media Relations Felix Gold Limited ​ ​ ​ ​ ​ Ph: 1300 805 795 Ph: +61 422 955 411 ​ ​ ​ ​ ​ E: ir@reachmarkets.com.au E: joe.webb@felixgold.com.au To stay up to date with company news, register your details on the Felix Gold investor portal​ ​ Thursday, 12th June 10am (AEST)​ Join Executive Director of Felix Gold, Joe Webb, for an online investor briefing​ Register here: https://felixgold.investorportal.com.au/investor-briefing ​ About Felix Gold Felix Gold Limited (ASX: FXG) is an ASX-listed gold and critical minerals discovery business operating in the highly endowed Tintina Gold Province of Alaska in the United States. Our flagship asset is a substantial landholding in the world-class Fairbanks Gold District, where historical gold production exceeds 16 Moz and historical antimony production shows grades up to 58% Sb from the Scrafford Mine, Alaska's second-largest historical antimony producer. In Fairbanks, our tenements sit within one of the largest gold production centres in the entire Tintina belt and lie in close proximity to both Kinross Gold’s Tier 1 gold mine, Fort Knox, and the rapidly growing Freegold Ventures’ discovery, Golden Summit. Felix’s key projects are located only 20 minutes from our operational base in the central mining services hub of Fairbanks City, Alaska. This base is a huge advantage for Felix with its existing infrastructure, low-cost power, skilled workforce and long history of gold and antimony production. It allows us to explore year-round and delivers genuine potential development pathways for our assets. Felix’s value proposition is simple: we are striving to be the premier gold and critical minerals exploration business in the Tintina Province through the aggressive pursuit and realisation of Tier 1 gold discoveries.​ ​ Visit the Felix Gold website for more information.
