Perpetua Resources is trading 4.5% higher at $21.61 in pre-market action as investors continue to react to the recent opening of its U.S. Army–backed antimony trisulfide pilot plant at Idaho National Laboratory.
- The facility is a key milestone in securing a domestic supply of antimony trisulfide, a critical mineral used in defense and energy storage applications.
- The stock's performance aligns with broader strength in the materials sector, which is benefiting from rising commodity prices and a positive risk-on sentiment in equity futures.
