NevGold Announces Up to 99% Gold Recovery From Phase II Metallurgical Testwork on Oxide Antimony-Gold; Identifies More Antimony Mineralization At Surface In Historical Gold Waste Dump
Advancing a dual-track oxide gold and critical mineral antimony strategy in Nevada.
The most recent news (April 2, 2026) reports Phase II metallurgical results for the Limousine Butte Project in Nevada. Key findings include gold recoveries exceeding 93% (up to 99%) from residual tailings after antimony has been leached. This confirms that a sequential leaching flowsheet—recovering antimony first via acid leach and then gold via cyanide leach—is technically feasible with minimal interference between the two processes. Additionally, the company identified new surface antimony mineralization in a historical waste dump and confirmed that the Mineral Resource Estimate (MRE) for the historical leach pads is on track for early Q2-2026.
The news is Material - Positive because it provides the final metallurgical "proof of concept" required to advance the project toward a near-term production scenario. - De-risking the Flowsheet: Achieving >93% gold recovery after antimony extraction removes a major technical hurdle. Investors often fear that complex metallurgy in poly-metallic deposits leads to high "penalty" losses; these results suggest the opposite. - Near-Term Cash Flow Potential: By confirming the viability of processing historical leach pads (2.4M to 3.0M tonnes of material already above ground), NevGold is shifting from a pure exploration play to a potential producer by 2027. - Strategic Alignment: The identification of further surface antimony in waste dumps adds "free" tonnage to a project already benefiting from the U.S. government's urgent mandate to secure domestic antimony (a critical mineral for defense and energy).
NevGold is a North American explorer focused on "Tier 1" jurisdictions (Nevada and Idaho). Its flagship is the Limousine Butte Project (Nevada), a Carlin-type gold system with a significant, high-grade oxide antimony component. The project is unique because it contains historical leach pads and waste dumps that allow for a "staged development" approach—targeting low-capex antimony production in the near term while defining a larger multi-million ounce gold resource for the long term.
