Spartan Metals Identifies Two New Tungsten-Silver-Rubidium Targets at its Eagle Project, Nevada

The most recent news release from December 9, 2025, states that Spartan Metals Corp. has identified two new tungsten-silver-rubidium exploration targets at its 100% owned Eagle Project in eastern Nevada, specifically at the Tungstonia deposit. These targets were defined based on results from a 2025 surface soil sampling program. Key highlights include soil sample grades up to 272 ppm tungsten, 5.9 g/t silver, and 537 ppm rubidium. The company notes that the strength and extent of these anomalies, in some cases exceeding those observed around the past-producing Tungstonia mine, suggest the potential for a significantly larger mineral system than historically recognized. Spartan Metals plans to conduct additional soil sampling, with the goal of generating drill targets for a program in the spring of 2026. The CEO, Brett Marsh, emphasized that these results validate their exploration model and are important steps towards defining drill targets.

This news is a positive development that aligns with the company's stated exploration strategy and previous commitments. It demonstrates progress from the initial rock chip sampling (August 2025) and the commencement of the exploration program (October 2025). The identification of new targets from soil sampling is a logical and necessary step in early-stage exploration, moving the project closer to drill-ready status.

The results, with anomalous tungsten, silver, and rubidium, are encouraging, especially the CEO's comment that they "exceed those observed around the past-producing Tungstonia mine," which hints at district-scale potential. However, soil sampling, while a good indicator, is not as definitive as drill results. The impact is routine in the sense that this is expected exploration progress for a company at this stage, but it is positive as it confirms and extends the mineral potential, reinforcing the narrative around the Eagle Project's critical mineral importance.

The company has been actively building its exploration team and marketing efforts, including recent management appointments (Rebecca Ball as VP Exploration) and multiple investor relations agreements. These new targets provide a tangible outcome of the initiated exploration program and give substance to the ongoing marketing efforts. The next crucial step will be defining and executing the planned drill program, as soil anomalies need to be tested at depth to confirm economic viability. The news does not provide an immediate game-changing impact but steadily de-risks the project by validating exploration models and advancing towards drilling.

Spartan Metals Corp. is a Canadian exploration company focused on developing critical minerals projects in top-tier mining jurisdictions in the Western United States. Its primary strategic focus is on building a portfolio of diverse strategic defense minerals, including tungsten, rubidium, antimony, bismuth, and arsenic, with an emphasis on U.S. critical metal onshoring objectives.

The company's flagship project is the Eagle Tungsten-Silver-Rubidium Project, located in White Pine County, eastern Nevada, USA. Spartan acquired 100% ownership of the project on July 31, 2025. The Eagle Project incorporates the historic Tungstonia and Rees mines, which historically produced 8,352 tonnes of tungsten trioxide (WO3) with average grades of 0.6% to 1.0% between 1917 and 1956. Beyond tungsten, the project is known to contain significant concentrations of rubidium, silver, copper, antimony, lead, and zinc. Recent exploration efforts by Spartan have aimed to confirm historical data, identify new mineralization, and expand the known prospective areas. The company doubled its land position at the Tungstonia claim block in November 2025, significantly expanding the exploration footprint.
