Military Metals Soil Survey Reveals 815-Meter Antimony Anomaly at Last Chance Nevada

An 815-meter northwest-southeast trend of anomalous antimony in B-horizon soils has been mapped at the Last Chance antimony project, a past-producing property owned by Military Metals Corp. The company reported that upper-decile soil assays ranged roughly 53.5 to 952 ppm Sb, while selective spring 2025 grab samples returned very high antimony values, with individual samples up to about 11.6% Sb. The data will be used to define drill targets for follow-up exploration.

The Last Chance property sits about 12 km west of Kinross’ Round Mountain mine and roughly 70 km north of Tonopah, placing the anomaly well within existing mining country that has established access roads and regional services. Military Metals framed the work in the context of antimony’s designation as a U.S. critical mineral and noted historical small-scale production at the site. The company released the soil-orientation results and technical notes on January 21, 2026, describing the 2025 sampling program and assay statistics.

From a technical standpoint, the distinction between B-horizon soil anomalies and high-grade grab samples is important. B-horizon anomalies measured in the high tens to low thousands of parts per million signal a robust geochemical footprint across an 815-meter trend, while grab samples exceeding 11 percent Sb, equivalent to roughly 116,000 ppm, represent localized concentrations that warrant targeted follow-up. Together these lines of evidence give the company geochemical templates to prioritize drill fences and test beneath soil anomalies.

For Nye County residents, the development could translate into increased exploration activity, short-term employment for drilling and surveying crews, and heightened permitting and road use around Last Chance. Investors and regional suppliers often view proximity to major operations like Round Mountain as a de-risking factor because infrastructure, power and services are already nearby. At the same time, any uptick in exploration raises questions about environmental review, water use and reclamation that will be part of permitting discussions if drilling is proposed.

On a broader scale, the result fits within a national push to secure domestic supplies of critical minerals. If follow-up drilling substantiates mineralization at depth, Last Chance could contribute to U.S. antimony supply chain resilience, an issue the federal government has prioritized. For now, Military Metals’ next steps are to translate the soil anomaly into drill targets and to seek the necessary permits and funding for a drilling program. Local stakeholders should expect more detailed technical reports and permit filings as the company moves from geochemistry to drilling.
