Spartan Metals Expands Past-Producing Tungstonia Mine Mineralization Footprint More Than 13-Fold, Defining 5.7 km2 of Tungsten-Silver Veins with Assays up to 5.18% WO3
Spartan expands its Eagle Project tungsten footprint thirteen-fold to target domestic critical metal supply.
Spartan Metals Corp. announced a significant expansion of tungsten-silver mineralization at its 100% owned Eagle Project in Nevada. The company defined eight tungsten-silver veins over a 5.7 km² area, representing a 13-fold increase in defined mineralization compared to the area known at acquisition in July 2025. Cumulative surface strike length is approximately 6.8 km, with rock samples returning up to 5.18% WO3 and significant silver values. Specific veins (Vein 4, Spartan C, B, A) have been extended, with Vein 4 showing 5.18% WO3 over a 1.1 km length.
Approximately 50% of the Tungstonia Claims remain unexplored. Next steps include ~3,000 meters of diamond core drilling starting mid-August 2026, supported by ongoing ground geophysics. Strategic context emphasizes U.S. critical mineral independence, noting China's ~80% global tungsten production share and the lack of commercial U.S. tungsten mining since 2015.
Spartan Metals Corp. (W) released a routine positive exploration update that confirms the expansion of its mineralized footprint and validates historic high-grade assays, aligning with the company’s prior 2026 exploration roadmap. The market has already priced in the acquisition of the Eagle Project and early exploration successes, with the stock rallying to $0.84 in March 2026. The current update is consistent with expectations and does not introduce a transformative catalyst or a material miss.
Spartan Metals Corp. is a critical minerals exploration company focused on its 100% owned Eagle Project in White Pine County, Nevada. The project encompasses past-producing tungsten mines, including Tungstonia, Rees, Antelope, and Yellow Jacket, and covers approximately 36.5 km² (9,033 acres). Deposit types at the site include Porphyry, Skarn, and Carbonate Replacement Deposits (CRD). Primary commodities include Tungsten (W), Rubidium (Rb), and Silver (Ag), with secondary commodities comprising Copper, Antimony, Arsenic, Bismuth, and Indium. The company is also advancing the Victorio Tungsten-Molybdenum Project in New Mexico, which it acquired via an option agreement in March 2026.
