NevGold Announces Up to 85% Antimony Recovery From Positive Phase II Metallurgical Testwork at Oxide Gold-Antimony Limo Butte Project in Nevada
None
The November 5, 2025 news release announces positive results from the Phase II antimony metallurgical testwork program at its Limousine Butte Project in Nevada. Key takeaways include: - Antimony recoveries ranged from 54% to 92% via leaching across a wide spectrum of grades from 0.1% Sb to 8.5% Sb. - Importantly, recoveries in the lower-grade 0.1%-0.2% Sb range were unexpectedly high at 71% to 85%. - The company states these results significantly de-risk the project's metallurgy and unlock the gold-antimony potential. - The ongoing 2025 drilling program has completed 13 holes, with the company awaiting assays, particularly from follow-up drilling at the new high-grade "Bullet Zone" discovery. - The company also announced the retention of GRA Enterprises LLC for marketing and advertising services for a fee of US$100,000 for a 12-month term.
The news is materially positive. While not a new discovery, these metallurgical results are a critical de-risking milestone that confirms and builds upon the initial positive results from July 2025.
- Confirmation and Expansion: The Phase II results validate the initial Phase I findings that antimony is recoverable via conventional methods. Crucially, this second phase tested a much wider range of grades, representative of what might be encountered in a potential mining scenario.
- Economic Significance: The high recoveries (71%-85%) on lower-grade material (0.1%-0.2% Sb) are particularly significant. This suggests that material previously considered low-grade or waste could potentially be economic, which could have a major positive impact on the future mineral resource estimate (MRE) and project economics.
- Project Advancement: This successful metallurgical work is a key prerequisite for the planned initial MRE. It demonstrates a clear path forward on the processing side and allows for more confident assumptions regarding recoveries to be used in resource calculations. The company has systematically advanced the project in 2025, from identifying the antimony potential, releasing historical data, making a new discovery, and now successfully completing two phases of metallurgical testing. This execution builds credibility.
- Context of Prior News: The entire focus in 2025 has been the emergence of Limo Butte as a significant gold-antimony project, a pivot from its prior gold-only focus. This news directly follows the major high-grade "Bullet Zone" discovery announced on October 16, 2025. While the discovery provided the grade and exploration upside, this metallurgical news provides the technical validation that the discovered mineralization could be processed economically.
The engagement of another marketing firm is routine but signals an intent to increase market awareness, which is logical given the stream of positive news and the upcoming MRE catalyst. Overall, this release strongly reinforces the investment thesis and demonstrates competent, systematic project advancement.
NevGold Corp. is a Canadian-based exploration company with a portfolio of projects in the western USA. Its flagship asset is the Limousine Butte (Limo Butte) Project in Nevada. While historically explored for gold, NevGold's work in 2025 has uncovered significant potential for antimony, a federally designated critical mineral in the US. The company's strategy has pivoted to advance Limo Butte as a dual-commodity gold-antimony project. The company also holds the Nutmeg Mountain gold project and the Zeus copper project, both in Idaho.
