- 01Near-surface gold confirmed with high-grade intersections at NW Array.
- 02Gold-antimony co-occurrence strengthens dual-commodity system potential.
- 03Development hinges on economic viability studies and regulatory approvals.
Felix Gold (ASX: FXG) has released its final 2025 assay results from the NW Array prospect at its Treasure Creek Project, confirming multiple near-surface gold intersections including high-grade, structurally controlled intervals.
Importantly, the results also highlight the co-occurrence of gold within high-grade antimony zones, strengthening the geological case for a dual-commodity system at the Alaskan project.
The results are from 22 diamond core and two reverse circulation (RC) holes, providing a comprehensive picture of the mineralisation.
The most notable gold intersection reported is 29.26 metres @ 2.16 grams per tonne Au from 13.41 metres, which includes a higher-grade zone of 21.03 metres @ 2.83 g/t Au.
The same hole also delivered 9.10 metres @ 1.92 g/t Au from 3.38 metres, demonstrating shallow, high-grade potential.
Dual-Commodity Potential Strengthened
Other significant gold results from the program include 28.65 metres @ 0.89 g/t Au and 19.35 metres @ 1.42 g/t Au.
The latest results are particularly compelling for Felix Gold's dual-commodity strategy, with assays as high as 4.74g/t Au revealing the co-occurrence of gold within high-grade stibnite zones.
Key antimony intersections include 2.53 metres @ 4.34% Sb, featuring a high-grade component of 0.50 metres @ 20.85% Sb.
Another strong antimony intercept was 3.36 metres @ 2.20% Sb, including 0.47 metres @ 13.59% Sb in hole 25TCDC059.
This finding reinforces the geological model that a single structural system at NW Array hosts both gold and antimony, potentially enhancing the project's overall value and development optionality.
Development & Exploration Progress
Felix Gold has made a series of positive advancements at its Treasure Creek Project, where the company is primarily focused on achieving near-term antimony production, with bulk sampling operations already underway.
This follows the Alaska Department of Natural Resources' approval of a permit amendment in March 2026, authorising the extraction of approximately 1,600 tons (about 1,450 metric tonnes) of high-grade massive stibnite material.
Metallurgical test work results from the same month confirmed that Felix Gold's hand-sorted massive stibnite ore exceeds US Military Concentrate Specification MIL-A-22131 as direct ore.
Independent programs demonstrated viable ore-to-metal processing pathways through direct smelting and alkaline sulphide leach followed by electrowinning, and Worley has also completed a US processing facility site selection assessment.
Economic Viability and Future Steps
Reinforcing its long-term tenure, Felix Gold secured 100% ownership of two upland mining leases and 25 mining claims at Treasure Creek in March 2026, with a remaining consideration of US$1.4 million due.
Previous drilling in April 2026 also confirmed additional near-surface gold zones at NW Array, including 37.65 metres @ 2.02 g/t Au.
While the exploration results are encouraging, Felix Gold has reiterated that no Mineral Resources or Ore Reserves have been declared, and that the economic viability of the project remains under assessment.
Progression toward antimony production is subject to further technical, regulatory, and commercial evaluations, as well as final Board approval.
The company will utilise the latest drill results to refine its geological model and define targets for future drilling programmes, aiming to advance both its gold and antimony prospects.
