Tier One Silver Intersects 0.7 Metres of 1,015 g/t Silver and 4.52 g/t Gold at Curibaya

The most recent release (April 21, 2026) reports Phase 2 drilling results from the Curibaya project in Peru. Key highlights include a high-grade intercept of 0.7 metres grading 1,015 g/t Silver and 4.52 g/t Gold in hole 26CUR-018. The company confirms continuity of mineralization across approximately 6 km of structures and demonstrates vertical consistency relative to Phase 1 drilling. Management is advancing permit applications (EIA-sd) to increase drilling capacity from 17 holes to up to 220 holes, with submission expected in Q3 2026. The program also identified potential porphyry copper-type system indicators including skarn mineralization and copper-bearing breccias grading up to 6% copper.

The news validates the high-grade epithermal model previously announced during the Phase 2 commencement updates in January and February 2026. While the intercepts are exceptional (1,015 g/t Ag), they confirm expectations rather than introducing a fundamentally new discovery scale that would immediately warrant a resource estimate. The stock price has already corrected from its January peak ($0.19) to current levels ($0.10), suggesting the market had priced in the potential of this program. The announcement is positive but incremental, serving as confirmation of the exploration thesis rather than a game-changing event like a maiden resource release or production start.

Tier One Silver is an exploration company focused on developing world-class silver-gold discoveries in Peru. The flagship asset is the Curibaya project, located on a prolific copper porphyry belt surrounded by major mines (Cerro Verde, Toquepala). The project hosts six high-grade silver-gold mineralized corridors and a notable copper porphyry target. As of April 2026, the company remains in the exploration phase with no production guidance or reserves disclosed.
