Positioned for Growth in America’s Critical Mineral Supply Chain

Spartan’s portfolio targets minerals central to U.S. industrial resilience and national security - all of which the U.S. currently imports in large part or entirely.
‍
As U.S. policy accelerates support for domestic sourcing of defense and technology metals, Spartan is uniquely positioned to benefit from both geological potential and national demand.
