🟢 Perpetua Resources is trading 5% up in after-hours trading — catalyst remains unconfirmed

Perpetua Resources is trading 4.84% up at $23.60 after closing at $22.51 on September 16, 2026; no company-specific catalyst is confirmed.

• Searches found no confirmed announcement, earnings release, or late-breaking catalyst dated September 16.
• The latest clearly identified financial-results release was dated August 17; Reuters coverage concerns earlier antimony-processing discussions.
• The broader market was weak after the Federal Reserve’s rate hike, so macro sentiment does not clearly explain the contrary-direction move.
