# Western Star Advances Domestic Tungsten Supply

Western Star Resources Inc. is advancing a U.S.-focused strategy to revitalize domestic tungsten production by developing past-producing assets in Nevada and New Mexico. This effort supports secure North American supply chains for tungsten, a critical mineral essential for defense applications such as armor-piercing munitions and kinetic-energy penetrators. The upcoming January 1, 2027 DFARS regulation imposes binding constraints favoring tungsten sourced from compliant non-Chinese suppliers, increasing demand for domestic production.

- **Why this matters:** Procurement professionals should anticipate increased sourcing requirements for tungsten that comply with DFARS restrictions effective January 2027, emphasizing non-Chinese origin.
- Western Star's projects in Nevada and New Mexico represent key opportunities to secure strategic mineral supply chains critical to defense manufacturing.
- Contractors and suppliers involved in defense materials and tooling should evaluate partnerships or supply agreements with domestic tungsten producers to meet regulatory and operational needs.
- This development signals a broader government emphasis on securing critical mineral supply chains within North America, impacting procurement planning and risk management.
