From Gold Rush Waste to Critical Mineral Treasure: A Nevada Explorer's Plan to Secure America's Antimony Supply

NEW YORK, NY – April 23, 2026 – By Sandra Patterson

A geopolitical showdown over a little-known but vital mineral is fueling a high-stakes resource race across the American West. The mineral is antimony, and with the United States 100% dependent on imports and its primary supplier, China, restricting exports, Washington is urgently seeking a domestic supply. Amid this scramble, a junior exploration company, NevGold Corp., has made a series of rapid-fire announcements that position it as a key contender in rebuilding this critical supply chain from the ground up, using an innovative approach that turns a previous generation's mining waste into a 21st-century strategic asset.

In a span of just six weeks, NevGold has secured over C$42 million in financing, announced high-grade antimony and gold drill results from its Limousine Butte project in Nevada, and confirmed exceptional metallurgical recoveries. The company's strategy bypasses the lengthy and costly process of developing a new mine, instead focusing on reprocessing historical leach pads left over from the 1980s—a plan that could fast-track it to production by 2027.

The National Security Imperative

Until recently, antimony was an obscure entry on the periodic table for most. Today, it is a matter of national security. The U.S. Geological Survey designates it as a critical mineral essential for defense applications, including armor-piercing munitions, night-vision goggles, and infrared sensors. It is also a key component in flame retardants and emerging technologies like advanced batteries and semiconductors.

The strategic vulnerability of the U.S. was laid bare in December 2024 when China, which dominates global production, imposed export restrictions specifically targeting the United States. While those restrictions were temporarily suspended in late 2025, a stringent licensing system remains, and the ban on exports for U.S. military end-users is still in force. The market shock was immediate, with antimony prices reportedly tripling and underscoring the precariousness of a supply chain entirely reliant on foreign, and often adversarial, nations.

In response, Washington has begun deploying significant capital through the Department of War (DoW) and the U.S. Export-Import Bank, committing billions to a handful of companies with viable domestic antimony projects. The bottleneck isn't money; it's the scarcity of advanced-stage, permitted projects that can deliver oxide antimony ore in the near term.

NevGold's Breakthroughs at Limousine Butte

It is within this high-pressure environment that NevGold has delivered a string of catalysts. On April 20, the company announced it had upsized a planned C$25 million financing to a staggering C$42.2 million, a 69% increase driven by overwhelming investor demand. This capital injection fully funds NevGold through its next critical milestones, including a 20,000-meter drill program and the delivery of a maiden Mineral Resource Estimate (MRE) for Limousine Butte, expected in the second quarter of 2026.

That funding arrives on the back of compelling geological results. On April 9, NevGold reported drill intercepts at the Resurrection Ridge prospect that included a high-grade core of 1.11% antimony over 6.1 meters, located within a much larger mineralized zone of 1.93 g/t gold equivalent over 100.6 meters starting directly from the surface. CEO Brandon Bonifacio described the project as “one of the highest grade antimony projects in North America that is near-surface and oxide,” a combination that is ideal for low-cost processing.

The most economically significant news, however, may have come from the metallurgy lab. On April 2, the company revealed that a sequential leaching process—extracting antimony first, then gold—was highly effective. Phase II tests on material from historical leach pads showed antimony extraction as high as 92%. Critically, subsequent cyanide testing on the remaining material recovered up to 99% of the gold. This confirms that the two metals can be recovered from the same feedstock without interfering with one another, unlocking the potential for two distinct revenue streams from a single operation.

The Brownfield Advantage: A Faster Path to Production

NevGold's core strategy is what sets it apart from many competitors. Instead of a traditional greenfield project, which involves discovering a deposit and building a mine from scratch, NevGold is focused on a brownfield site. The antimony and gold it is targeting for 2027 production are contained within large leach pads and waste dumps—already-crushed rock that was mined for gold between 1989 and 1990, when antimony was not considered economic.

This “re-mining” approach carries a structurally different and lower risk profile. It eliminates the need for new mining activities to initiate production, drastically shortening timelines and reducing initial capital costs. Follow-up sonic drilling on the pads, announced on April 14, confirmed consistent grades that were even higher than initial sampling, including 0.34% antimony and 0.41 g/t gold over 12.5 meters. This data will feed directly into the upcoming MRE and a future economic study.

Further de-risking the project, the entire 68-square-kilometer Limousine Butte property is covered by a U.S. Bureau of Land Management-approved Plan of Operations. This 10-year permit allows for up to 200 acres of disturbance, providing a clear regulatory path for the exploration and development activities required to bring the historical pads into production.

Assembling a Domestic Supply Chain

NevGold is entering an active field where a new, vertically integrated American antimony supply chain is being assembled in real time. Several other publicly traded companies are advancing projects with significant government and institutional backing:

• Perpetua Resources (NASDAQ: PPTA) is the most advanced player, with its Stibnite Gold-Antimony Project in Idaho potentially supplying up to 35% of U.S. demand. The company is seeking a $2.7 billion loan from the EXIM Bank to fund construction.
• United States Antimony Corporation (NYSE: UAMY) operates the only antimony smelter in the U.S. and is a direct recipient of Department of War funding to expand its capabilities and integrate its own mining sources.
• Nova Minerals (NASDAQ: NVA) is developing a project in Alaska, backed by a $43.4 million award from the DoW, and is targeting first antimony production in late 2026 or 2027.
• Americas Gold and Silver (NYSE American: USAS), which operates what it calls the only currently producing antimony mine in the U.S., has formed a joint venture with UAMY to build a processing facility in Idaho, a clear example of miners and processors collaborating to close the supply chain loop.

Within this landscape, NevGold's Limousine Butte project offers a unique proposition. It combines the near-term production potential of reprocessing with the exploration upside of a large, mineral-rich land package. With a freshly fortified treasury of over C$50 million, a clear path to a maiden resource, and a proven metallurgical process that unlocks both gold and antimony, the company is positioned at the intersection of geology, metallurgy, and geopolitics. As the U.S. government continues to fast-track domestic critical mineral projects, NevGold’s innovative plan to turn yesterday’s waste into tomorrow’s strategic resource is a development that the market and Washington will be watching closely.
