Felix Expands High-Grade NW Array Antimony

Why It Matters

The project could provide the United States with its first domestic source of high‑purity antimony, reducing reliance on China for a critical defense and technology metal. Its rapid‑development model may set a template for other strategic mineral projects.

Key Takeaways

• NW Array antimony grades up to 12.5% near surface
• Drill program expanded mineralized area to 250x400m
• Project aims to supply U.S. military‑grade antimony
• Infrastructure near Fairbanks enables rapid mine development
• No other non‑Chinese project offers comparable antimony quality

Pulse Analysis

Antimony, a silvery metalloid used in flame‑retardants, lead‑acid batteries, and high‑performance alloys, has become a strategic material for defense and electronics. The United States currently imports virtually all of its antimony, with the majority sourced from China, exposing supply chains to geopolitical risk. Recent policy initiatives, including the Department of Defense’s push for domestic critical minerals, have heightened interest in projects that can produce “military‑grade” antimony. In this environment, any new domestic source that can deliver high purity at scale is viewed as a national security asset.

Felix Gold’s NW Array on the Treasure Creek property stands out because it offers surface‑accessible, high‑grade antimony deposits rarely seen outside China. Drill results from the 2025 program show intercepts ranging from 3.1% to 12.5% antimony over intervals up to 17.9 meters, defining a roughly 250 by 400 meter zone of veining and breccia. The site benefits from existing highway access, power lines, and a nearby community, allowing the company to pursue a “precision‑scale” quarry‑style operation rather than a large‑scale mine. Parallel workstreams—drilling, metallurgical testing, permitting, and stakeholder engagement—are intended to compress the timeline to first production.

If Felix can bring the NW Array into commercial operation, it would not only fill a critical gap in the U.S. antimony supply chain but also demonstrate a replicable model for other strategic minerals. The company is already courting strategic partners and potential off‑take agreements, positioning the project as a long‑term feedstock for domestic refiners and defense manufacturers. Success could encourage further investment in Alaska’s mineral‑rich regions, where infrastructure is already in place, and could spur policy makers to support similar fast‑track approvals for critical‑metal projects. Ultimately, a reliable domestic antimony source would bolster U.S. manufacturing resilience and reduce exposure to external supply shocks.
