Treasure Creek Drilling Yields 36.65% Antimony Over 1.63m Near Surface

Drilling Success at NW Array

Felix Gold Limited (ASX:FXG) has announced compelling results from its 2025 drilling campaign at the Treasure Creek project in Alaska’s Fairbanks Mining District. The latest batch of assays confirms the extension of a high-grade antimony system known as the NW Array, with significant new intersections reported both west and south of the previously defined mineralised area.

Among the standout results is an intersection of 8.67 metres grading 12.51% antimony from just 17 metres depth, including a remarkable 1.63 metres at 36.65% Sb. These grades are exceptionally rare globally, especially at such shallow depths, and highlight the potential for near-term mining development.

Dual Commodity Potential: Antimony and Gold

Felix Gold’s drilling also continues to reveal gold mineralisation intimately associated with the antimony veins. For example, hole 25TCDC022 returned 25.61 metres at 2.03 grams per tonne gold, including 11.51 metres at 3.88 g/t Au, interpreted as a broader halo around the antimony-bearing breccia structures. This dual commodity system adds strategic value, offering both critical mineral supply and precious metal upside.

The company’s Executive Director, Joseph Webb, emphasised that the ore quality is a key differentiator. The Treasure Creek system produces a clean, high-grade antimony concentrate capable of military-grade specifications, a claim unmatched by any other known Western project outside China. This positions Felix Gold as a potential cornerstone in rebuilding a secure US antimony supply chain, critical for defence and industrial applications.

Strategic Location and Infrastructure Advantages

The Treasure Creek project benefits from excellent infrastructure, including year-round paved road access and grid power, located just 30 kilometres from Fairbanks. This proximity reduces permitting complexity and development timelines compared to many other critical minerals projects in the US. Felix Gold is advancing multiple workstreams in parallel; drilling to expand the resource, permitting for near-term mining, metallurgical testing for refining pathways, and commercial discussions with strategic partners.

While no JORC-compliant Mineral Resources or Ore Reserves have yet been declared for antimony, the ongoing drilling program and assay results are building a robust geological model. The mineralised system remains open in multiple directions, with further assay results pending from 14 diamond holes and 1 RC hole for antimony, and gold assays awaited from 43 diamond and 18 RC holes.

Looking Ahead

Felix Gold’s methodical approach and high-grade results underscore the growing importance of Treasure Creek as a domestic US antimony source. The company’s focus on ore quality, strategic location, and dual commodity potential could position it as a leader in critical minerals supply. However, economic viability and formal resource declarations remain to be established through further technical and regulatory work.
