American Tungsten Provides Operation and Development Update

Executive Summary
- Completed rehabilitation of ~1,000 ft of the D‑level adit at the IMA Mine and began underground infrastructure work to support an upcoming 5,000‑ft diamond drill program slated for mid‑November 2025.
- Launched a metallurgical testwork and flowsheet development program with WSP to evaluate transitioning from a Direct Shipping Ore (DSO) model to a full‑scale on‑site milling operation.
- Initiated historical data validation activities, including re‑packaging of 2008 drill pulps, check assays, and an underground channel sampling program targeting the No. 5 and No. 7 vein systems.
