Endeavour Silver Provides Q1 2024 Construction Progress Update on Terronera; Construction Progress Reaches 53% Completion - Seite 3

Environmental – Environmental and social assessment initiatives continue according to schedule as outlined under the Equator Principal requirements for project loan financing.

Next Steps and Planning

The Terronera Project is on track for commissioning in Q4 2024.

For Q2 2024, surface construction will continue focusing on mechanical installations and initial electrical work for the crushing, coarse-ore stockpile, grinding, flotation and tailing thickener areas. Excavation of the Lower Platform is anticipated to be complete in the coming months. Concrete work is expected to be initiated for the LNG and power generation and concentrate and tailing filtration. Concentrate and tailing filtration structural, mechanical, and electrical installations will commence in early Q3.

Mine development in Portal 1, 2 and 4 declines will continue with first ore development anticipated in Q2. Initial long-hole mining is planned for Q3 followed by cut-and-fill mining; ore will be stockpiled for mill ramp up. Development activities at La Luz are anticipated to begin in Q2 with portal construction and ramp advance to ore access anticipated in Q4. The critical path remains the TSF and lower platform construction and advancing underground mine, where development is meeting expectations.
