Spartan Metals said its recently staked land expansion of the Tungstonia Claim block at its 100 percent owned Eagle Project in eastern Nevada, includes the acquisition of the past producing Yellow Jacket Tungsten Mine. The Yellow Jacket Tungsten Mine is located approximately 2 kilometers (km) of the legacy Tungstonia Mine.
“Acquiring an additional, past producing tungsten mine in the district is an exciting development for Spartan as it allows the team to evaluate and explore both the vein system at Tungstonia and skarn type mineralization potential at Yellow Jacket. Our geologic work continues to expand the footprint of tungsten mineralization at the Eagle Project that commonly exceeds 1.0 percent WO3,” said Rebecca Ball, Spartan’s VP of Exploration.
“The higher-grade material that was historically produced from the Yellow Jacket Tungsten Mine combined with the known production from our Tungstonia and Rees tungsten mines indicates a significant tungsten endowment in the district, and we are focused on expanding this district-scale exploration project,” added Ball.
Planned activities for 2026 include:
• Additional soil sampling over the newly staked ground at Tungstonia (including at Yellow Jacket)
• Geophysics over the entire Tungstonia Claim block
• Diamond core drilling of high potential targets
The Yellow Jacket Claims were historically mined as a skarn style deposit with scheelite mineralization hosted within the favorable Guilmette formation carbonates along the contact with the Tungstonia Pluton. The Guilmette is also in contact with the Tungstonia Pluton at the Rees Mine with known scheelite mineralization and along the southern edge of the Tungstonia Pluton where Spartan recently identified a large tungsten soil anomaly.
The presence of this large tungsten soil anomaly at this favorable contact and its similarity to the Yellow Jacket and Rees mines suggests the potential for strong, skarn type mineralization at the newly identified tungsten target in the southeast portion of the Tungstonia claim block. Similar projects hosted in Guilmette formation are Kinross’s Alligator Ridge and Bald Mountain deposits and Ridgeline Minerals Selena project as a few among many others in Nevada.
Spartan Metals is focused on developing critical minerals projects in well-established and stable mining jurisdictions in the Western United States, with an emphasis on building a portfolio of diverse strategic defense minerals such as tungsten, rubidium, antimony, bismuth, and arsenic. Spartan’s flagship project is the Eagle Project in eastern Nevada that consists of the highest-grade historic tungsten resource along with significant under-defined resources consisting of: high-grade silver; rubidium; antimony; bismuth; indium; as well as precious and base metals.
