The United States faces a critical vulnerability in its defense supply chain: antimony, a metal essential for munitions, flame retardants, and night-vision equipment, has no domestic primary mine. With China controlling the vast majority of global supply, Washington is now scrambling to secure domestic sources. NevGold Corp. (TSXV: NAU) (OTCQX: NAUFF) (Frankfurt: 5E50) is positioning itself at the forefront of this effort through its Limousine Butte project in Nevada.
A Strategic Pivot from Gold to Critical Minerals
NevGold, a Vancouver-based exploration and development company, owns a portfolio of 100%-held projects across Nevada and Idaho. While initially focused on gold, the company's drilling at Limousine Butte repeatedly returned significant antimony grades alongside gold, revealing a dual commodity opportunity. The project is a brownfield site—a former mine with existing disturbance and historical infrastructure—hosting near-surface oxide mineralization amenable to heap leaching. This brownfield status can ease permitting and shorten development timelines, while oxide material is generally cheaper and faster to process than refractory sulphide ore.
Recent Catalysts: Funding and Drilling
In May 2026, NevGold closed an upsized brokered private placement of approximately C$42 million, providing one of the strongest treasuries among junior antimony-gold developers. This removes the financing overhang that often stalls exploration plays. Concurrently, the company commenced a 20,000-meter drill program at Limousine Butte, focused on resource building, expansion, and new discoveries.
Technical results have been encouraging. The company reported consistent oxide antimony-gold mineralization from the historic crushed leach pad, including an interval of 0.32% antimony and 0.39 g/t gold over 14.9 meters. In late May, surface sampling from the historical Pre-Strip Dump yielded grades up to 53.7% antimony, with fourteen samples exceeding 2% antimony. Earlier metallurgical testwork indicated up to 99% gold recovery and a processing sequence where antimony can be leached first with minimal impact on subsequent gold recovery—a potential pathway to near-term antimony production followed by gold extraction.
Addressing a National Security Gap
Antimony is classified as a critical mineral by the U.S. government, yet the country remains entirely dependent on imports, primarily from China. This dependency poses a strategic risk for defense applications. NevGold's Limousine Butte project, with its near-surface, leachable oxide mineralization and historical infrastructure, offers a rare opportunity to establish a domestic supply chain. The company targets a maiden antimony-gold resource in Q2 2026, which could mark a significant step toward reducing the U.S. antimony gap.
With a well-funded treasury and an aggressive drill program underway, NevGold is racing to close the antimony gap—and Washington is watching closely.
