Nicola Mining reopens Treasure Mountain Silver Mine portals, targets 2027 restart

• Nicola Mining reopened Portals 1 and 2 at the Treasure Mountain silver-lead-zinc mine in British Columbia to support a 2027 restart.
• An independent July 27, 2026 underground inspection found workings in better condition than expected following about 13 years of inactivity.
• Both portals remained accessible; no flooded sections or major collapse zones were encountered in inspected areas; ventilation was functioning.
• Rehabilitation is expected, with localized work flagged near the Portal 2 entrance before systems are recommissioned.
• Next steps include geotechnical work, rehabilitation planning, surveying, then mine planning to prioritize areas for renewed extraction.
