5.87m at 4.34% Sb Confirms NW Array’s Down-Dip Mineralisation Extension

Strong Assay Results Reinforce Felix Gold's Antimony Potential

Felix Gold Limited (ASX – FXG) has delivered a fresh wave of encouraging assay results from its NW Array gold-antimony prospect in Alaska’s Treasure Creek Project. The latest drilling confirms the down-dip extensions of high-grade antimony mineralisation previously identified at surface, with intervals including 5.87 metres grading 4.34% antimony, and ultra-high-grade veins reaching up to 38% antimony. These results underscore the continuity and quality of the mineralisation at relatively shallow depths, bolstering the project’s development prospects.

Executive Director Joe Webb highlighted the strategic significance of the timing, noting the acute supply shortages triggered by China’s export ban on antimony to the U.S. and the soaring antimony prices now exceeding US$60,000 per tonne. Situated just 20 minutes from Fairbanks, the project benefits from excellent infrastructure access, enabling Felix Gold to pursue a rapid development pathway targeting production within months rather than years.

Streamlined Development and Bulk Sampling Plans

Felix Gold has lodged a permit amendment to conduct a bulk sampling program of approximately 1,600 tonnes focusing on veins with near-pure stibnite, the primary antimony mineral. Metallurgical testing indicates the potential for a simple processing flow sheet involving excavation, hand sorting, and bagging, avoiding complex crushing or milling operations. This low-capital, modular approach aligns with the company’s strategy to start small and fast, reducing geological and environmental risks while addressing urgent U.S. supply chain needs.

Drilling remains active through the winter season, with 52 reverse circulation holes and 38 diamond core holes completed to date. While antimony assays are pending for 64 holes and gold assays for 90 holes, the ongoing program aims to better define the extent, grade, and geometry of the mineralisation. Environmental baseline studies and community engagement efforts are also underway, supporting a planned multi-year mining permit submission targeted for early Q1 2026.

Geopolitical Context and Market Implications

The project’s timing is particularly fortuitous given the U.S. government’s emergency declarations and funding initiatives to secure domestic critical mineral supplies. Antimony is essential across defense, clean energy, and industrial sectors, with no viable substitutes and a critical shortfall in U.S. stockpiles. Felix Gold’s proximity to infrastructure and straightforward processing route position it as a potential rapid-response supplier in a market dominated by China and Russia.

While no feasibility study has yet been completed and production scenarios remain conceptual, Felix Gold’s approach reflects a pragmatic response to a global supply crunch. The company’s focus on delivering near-term production, securing offtake agreements, and building a longer-term strategic operation aligns with federal priorities and market demand dynamics.

Looking Ahead

With high-grade antimony mineralisation confirmed and development activities accelerating, Felix Gold is poised to play a pivotal role in reshaping the U.S. critical minerals landscape. The coming months will be critical as assay results continue to flow, permitting advances, and feasibility work progresses, setting the stage for potential production and market impact in late 2025 and beyond.
