(1) Silver equivalent ratios for 2026 are calculated using 90:1 Ag:Au, 45 silver oz to 1 lead tonne; 61 silver oz to 1 zinc tonne; 238 silver oz to 1 copper tonne. Silver equivalent ratios for 2025 are calculated using 80:1 Ag:Au, 60 silver oz to 1 lead tonne; 85 silver oz to 1 zinc tonne; 300 silver oz to 1 copper tonne.
(2) These are non-IFRS financial measures and ratios. Further details on these non-IFRS financial measures and ratios are provided at the end of this press release and in the MD&A accompanying the Company’s financial statements, which can be viewed on the Company’s website, on SEDAR+ at www.sedarplus.com and on EDGAR at www.sec.gov.
(3) Bolañitos mine was sold January 15, 2026, and the 15-day period from January 1, 2026, to January 15, 2026, is included in the consolidated results above.
(4) Kolpa was acquired on May 1, 2025. Accordingly, the three- and six-month periods ending June 30, 2025 include two months of operations of the Kolpa mine.

Direct operating costs per tonne in Q2 2026 were $161.73, 14% higher than $142.00 in Q2 2025. The increase in the average cost compared to Q2 2025 was driven by the inclusion of Terronera with higher direct operating costs per tonne than the consolidated average of $169.49 and higher costs at Guanaceví and Kolpa. Underlying costs in Mexico were negatively affected by the Mexican peso being 12% stronger on average during the current period compared to the same period in 2025. In comparison to Q1 2026, which had a similar Mexican peso exchange rate, Q2 2026 costs per tonne were 13% lower. As a result, direct operating costs per tonne in the first half of 2026 were $173.63, compared to $142.30 in 2025.

Consolidated cash costs per silver ounce, net of by-product credits, were $23.52 in Q2 2026, representing a 53% increase from $15.35 in Q2 2025 mainly due to higher metal prices causing higher royalties and third-party material costs. For the three months ended June 30, 2026, cash costs per silver ounce were $22.23 for Kolpa, $40.17 for Guanaceví and $5.07 for Terronera. Cash costs per silver ounce for the six-month period ended June 30, 2026, were $23.03 compared to $15.59 in 2025, a 48% increase driven by the same reasons described above.

Consolidated AISC per silver ounce in Q2 2026 were $36.89, 47% higher than $25.16 in Q2 2025 and in line with Q1 2026. The increase compared to Q2 2025 was predominantly due to higher cash costs and higher sustaining capital expenditures, particularly at Terronera, which was not operating in the comparative period. AISC per silver ounce for the six-month period ended June 30, 2026, were $36.96 compared to $24.85 in 2025, for the same reasons described above.

In Q2 2026, the Company’s mine operating earnings were $74.0 million, higher than the $7.7 million for the same period in 2025, driven by higher metal prices as well as higher volume of silver and gold ounces sold with the addition of Terronera and a full quarter of Kolpa operations. Revenue from operations was $212.1 million, compared to $85.3 million in Q2 2025, while cost of sales, which now include Terronera and a full quarter of Kolpa operations, increased to $138.1 million from $80.9 million.

The Company recorded operating earnings of $64.7 million in Q2 2026 (Q2 2025 – operating loss of $4.8 million) after exploration and evaluation costs of $6.4 million (Q2 2025 – $4.9 million) and general and administrative expenses of $2.9 million (Q2 2025 – $7.6 million). Exploration expenses increased due to additional expenditures on advancing Pitarrilla and exploration work at Kolpa, while general and administrative expenses decreased predominantly due to the $3.6 million acquisition costs ineligible to be capitalized in Q2 2025 and a $1.6 million change in the loss on revaluation of the cash-settled deferred share units liability.

The Company recorded a $21.7 million gain on derivative contract revaluations in Q2 2026 (Q2 2025 – $10.1 million loss). Finance costs increased to $5.7 million (Q2 2025 – $1.1 million), primarily due to a $5.1 million finance charge related to the senior convertible notes issued in December 2025. Investment and other losses of $2.6 million (Q2 2025 – income of $0.7 million) were recorded during the period, largely due to the revaluation of Guanajuato Silver shares received as consideration for the sale of Bolañitos. As a result, earnings before taxes were $79.5 million in Q2 2026, compared to a loss before taxes of $14.6 million in Q2 2025.

Cautionary Note Regarding Forward-Looking Statements

This news release contains “forward-looking statements” within the meaning of the United States private securities litigation reform act of 1995 and “forward-looking information” within the meaning of applicable Canadian securities legislation. Such forward-looking statements and information herein include but are not limited to statements regarding advancing the Company’s growth initiatives in the second half of the year; mine complex ramp-up at the Terronera project; Endeavour’s ability to unlock value across the Company’s development pipeline and deliver long-term value for its stakeholders, and the timing and results of various activities. The Company does not intend to and does not assume any obligation to update such forward-looking statements or information, other than as required by applicable law.

Forward-looking statements or information involve known and unknown risks, uncertainties and other factors that may cause the actual results, level of activity, production levels, performance or achievements of Endeavour and its operations to be materially different from those expressed or implied by such statements. Such factors include but are not limited to unexpected changes in production and costs guidance; the ongoing effects of inflation and supply chain issues on mine economics; fluctuations in the prices of silver and gold; fluctuations in the currency markets (particularly the Mexican peso, Peruvian sol, Canadian dollar, Chilean peso, and U.S. dollar); fluctuations in interest rates; effects of inflation; changes in national and local governments, legislation, taxation, controls, regulations and political or economic developments in Canada, Peru and Mexico; operating or technical difficulties in mineral exploration, development and mining activities; risks and hazards of mineral exploration, development and mining (including, but not limited to, environmental hazards, industrial accidents, unusual or unexpected geological conditions, pressures, cave-ins and flooding); inadequate insurance, or inability to obtain insurance; availability of and costs associated with mining inputs and labour; the speculative nature of mineral exploration and development; diminishing quantities or grades of mineral reserves as properties are mined; risks in obtaining necessary licenses and permits; and challenges to the Company’s title to properties; as well as those factors described in the section “risk factors” contained in the Company’s most recent form 40F/Annual Information Form filed with the S.E.C. and Canadian securities regulatory authorities.

Forward-looking statements are based on assumptions management believes to be reasonable, including but not limited to: the continued operation of the Company’s mining operations, no material adverse change in the market price of commodities, forecasted mine economics, mining operations will operate and the mining products will be completed in accordance with management’s expectations and achieve their stated production outcomes, and such other assumptions and factors as set out herein. Although the Company has attempted to identify important factors that could cause actual results to differ materially from those contained in forward-looking statements or information, there may be other factors that cause results to be materially different from those anticipated, described, estimated, assessed or intended. There can be no assurance that any forward-looking statements or information will prove to be accurate as actual results and future events could differ materially from those anticipated in such statements or information. Accordingly, readers should not place undue reliance on forward-looking statements or information.


Risks

  • Higher cash costs and sustaining costs, partly due to increased royalties and third-party material costs, pressure margins impacting mining sector profitability.
  • Commodity price volatility, especially fluctuations in silver, gold, and base metal prices, could materially affect revenue and earnings.
  • Foreign exchange rate fluctuations (e.g., stronger Mexican peso) and potential operational or regulatory challenges in Mexico and Peru could impact costs and operational performance.
