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

Tier One Silver reported high-grade Phase 2 assay results at its Curibaya project (Apr 21, 2026), including a standout 0.7 m intercept grading 1,015 g/t Ag and 4.52 g/t Au within a broader 2.7 m interval of 284.4 g/t Ag and 1.29 g/t Au (hole 26CUR-018). Results confirm continuity of a high‑grade silver‑gold epithermal system across roughly 6 km of corridors and support lateral/vertical extension from Phase 1 targets. The company is advancing permit expansion to as many as 220 drill holes (EIA-sd application targeted for Q3 2026) to accelerate testing and scale definition. Market impact: these assay results are bullish for silver exploration sentiment (XAGUSD) and for Tier One Silver’s project valuation and financing prospects, potentially lifting investor interest in the junior and in silver-focused plays pending further assays.
