Endeavour Silver Intersects High-Grade Silver and Gold Mineralization at its Terronera Operation
Endeavour’s high-grade Terronera drill results extend mine life despite cost creep and reserve depletion at Guanaceví.

Executive Summary
- Endeavour Silver announced positive drill results from its 2025-2026 exploration program at the Terronera mine in Jalisco, Mexico.
- The program successfully extended high-grade silver and gold mineralization along strike and at depth across the La Luz and Terronera vein systems.
- Key intercepts include LL-43 (1.06m at 574 g/t Ag, 23.92 g/t Au) and TRU-001 (8.11m at 282 g/t Ag, 1.80 g/t Au).
- La Luz mining is scheduled to commence in 2027 using long hole and cut-and-fill methods.
- Two drill rigs are currently active, with testing expected through mid-Q4 2026.
- Results were analyzed by SGS laboratory and approved by Qualified Person Dale Mah, P.Geo.
Material Impact
- This is a Routine - Positive update. The drill results are expected and telegraphed by management's prior commitment to release exploration data in Q2.
- While the high-grade intercepts are geologically encouraging and support the 2027 La Luz ramp-up, they do not alter near-term production volumes, cost guidance, or capital allocation plans.
- The stock price has remained flat since the Q1 earnings release ($12.68 on May 6 to $12.49 on June 17), indicating the market had already priced in the operational context and these results are not a surprise.
