How Far Does Felix Gold’s High-Grade NW Array Gold Extend?
Felix Gold Limited has confirmed significant extensions to gold mineralisation at its NW Array prospect in Alaska's Treasure Creek, with high-grade assay results and broad gold halos around antimony veins. The mineralised system remains open for further expansion, supporting the company's dual-commodity strategy.
- 67m trench with 26m at 1.86 g/t gold extends mineralisation 130m west
- Multiple drill holes confirm broad gold zones around high-grade antimony veins
- 831,000-ounce JORC gold resource underpins strategic optionality
- Gold and antimony mineralisation coexist within the same structural corridor
- Proximity to Kinross Gold’s Fort Knox mill offers potential toll treatment opportunities
Overview of NW Array Drilling and Trenching Results
Felix Gold Limited (ASX, FXG) has released new assay results from its tightly focused drilling and trenching program at the NW Array prospect within the Treasure Creek project in Alaska. The program, initially designed to test high-grade antimony mineralisation, has also confirmed significant extensions of gold mineralisation, reinforcing the dual-commodity potential of the project.
A key highlight is the surface trench 25NWTR001, located approximately 130 metres west of the main 2025 drilling area. This trench exposed 67 metres of gold mineralisation across a 90-metre length, including a 26-metre interval grading 1.86 grams per tonne (g/t) gold, with a higher-grade 12-metre section at 2.86 g/t. These results extend the NW Array mineralised corridor into newly acquired ground, validating historical shallow drilling results.
Geological Context and Mineralisation Styles
The NW Array hosts both gold and antimony mineralisation within the same structural corridor. Gold typically forms broad halos around the antimony-bearing stibnite veins, particularly within brecciated fault zones. Drilling has identified two main mineralisation styles, east-west trending quartz vein zones dipping southwards, and broader 'black breccia' fault zones dipping southeast. High gold grades are commonly associated with these brecciated zones, which also contain antimony mineralisation.
Drill results continue to confirm broad zones of gold mineralisation enveloping the antimony veins, with significant intersections such as 47.36 metres at 1.34 g/t gold (including 7.09 metres at 2.27 g/t) and 15.71 metres at 2.91 g/t gold. The mineralised system remains open along strike and at depth, suggesting further exploration upside.
Strategic Positioning and Infrastructure Advantages
Felix Gold's Executive Director, Joseph Webb, emphasised the strategic value of the company's 831,000-ounce JORC gold resource in the Fairbanks Gold Mining District. The district is historically prolific, having produced over 16 million ounces of gold, and hosts Kinross Gold’s Fort Knox mill, a Tier 1 facility located just 30 kilometres from NW Array by paved road.
Kinross is actively seeking additional ore sources under its Alaska strategy, currently trucking ore from 400 kilometres away. Felix Gold’s proximity to this mill presents a potential toll treatment pathway for gold ore, complementing the company's immediate focus on establishing a fully integrated domestic antimony supply chain. The shared infrastructure, permitting, and baseline studies benefit both commodities, enhancing the project's development prospects.
Ongoing Work and Future Outlook
The 2025 drill program at NW Array is ongoing, with assay results pending for a significant number of diamond and reverse circulation holes. The program supports waste rock characterisation and near-term production studies, particularly for antimony. Felix Gold cautions that no mineral resources or ore reserves have been declared for antimony, and economic viability studies are underway.
The company’s dual focus on gold and antimony within the same structural corridor offers a unique value proposition. As drilling continues to delineate the extent and grade continuity of mineralisation, Felix Gold is well positioned to advance both commodities in parallel, leveraging the established infrastructure and strategic location within a premier mining district.
Bottom Line?
Felix Gold’s latest results bolster its dual-commodity strategy, but pending assays and economic studies will be critical to unlocking full project value.
Questions in the middle?
- What will the pending assay results reveal about the full extent and grade continuity of gold and antimony mineralisation?
- How will Felix Gold advance the economic viability and permitting for near-term antimony production?
- Could a toll treatment agreement with Kinross Gold’s Fort Knox mill materialise, and what impact would that have on project economics?
