Endeavour Silver has provided its 2026 guidance projecting combined silver production of 8.3–8.9 million ounces from its Terronera, Guanaceví and Kolpa mines, with gold output of 46,000–48,000 ounces from Terronera and Guanaceví. The newly integrated Kolpa operation is expected to deliver 22,000–24,000 tonnes of lead, 16,000–18,000 tonnes of zinc and 650–750 tonnes of copper. In aggregate, the three assets are forecast to produce between 14.6 million and 15.6 million silver equivalent ounces, reflecting the first full-year contribution from Terronera following commissioning in 2025 and the recent addition of Kolpa to the portfolio.

Endeavour forecasts consolidated cash costs of US$12.00–US$13.00 per payable silver ounce, driven lower by higher silver output and stronger by-product metal assumptions. All-in sustaining costs are expected to range US$27.00–US$28.00 per ounce, modestly higher than 2025 levels due to increased mine development at Terronera and post-acquisition capital investment at Kolpa. Terronera is projected to report negative net cash costs—between negative US$1.00 and negative US$2.00—on its higher gold-to-silver ratio, while Guanaceví’s unit costs are estimated at US$21.00–US$22.00 per ounce and Kolpa’s at US$13.00–US$14.00 per ounce, net of by-product credits.

The Company plans US$157.8 million in total capital expenditures for 2026, of which US$91.0 million is earmarked for sustaining capital across its operating mines and US$66.8 million is allocated to growth and greenfield projects. Terronera will receive US$56.7 million—split between US$32.9 million of mine development and US$23.8 million of infrastructure enhancements—while US$24.5 million is budgeted at Guanaceví and US$9.8 million at Kolpa. Growth capital includes US$48.0 million for the Pitarrilla project, US$1.8 million for regional exploration and US$0.3 million for corporate initiatives.
