Two Core Assets
Eagle Project (Nevada) - High Grade Tungsten
A past-producing, high-grade district-scale tungsten system with significant exploration upside.
Spartan launched its Phase 1 exploration program in 2025, including drilling and characterization of historic Tungstonia tailings to define grade, geometry, and recovery potential.
Results will guide a larger-scale drill campaign in 2026, targeting multiple high-priority zones across the district.
Victorio Project (New Mexico) - Large Scale Tungsten
The largest tungsten resource in the United States, with significant tonnage and development potential.
Spartan plans to:
• Develop exploration plans to unlock further value through systematic drilling and resource validation
• Update the 2008 PEA and Mineral Resource Estimate to reflect current tungsten prices and project economics
High‑Grade US Tungsten Project (Eagle)
Historic WO₃ production: ~0.6–0.9% from the past-producing Tungstonia mine; strong exploration upside.
Largest U.S. Tungsten Resource (Victorio)
Historic M&I + Inferred resource base with development potential
Multi‑Commodity Critical Minerals
W, Rb, Sb, Bi, Mo, As + Cu, Ag, In, Au, Pb, Zn identified at surface.
U.S. Department of War Alignment
Strategy focused on domestic supply for critical/defense minerals.
