Endeavour Silver reported a sharply stronger Q1 2026, driven by new mines and record metal prices. Revenue rose to $209.7M from $63.5M, while net earnings swung to a profit of $64.9M from a $32.9M loss. Silver-equivalent production increased 78% to 3.34M ounces as Terronera and Kolpa contributed meaningfully alongside Guanaceví. Operating cash flow strengthened and cash reached $231.8M, supporting shareholders’ equity of $644.7M. Profitability was partly offset by higher unit costs and a $24.2M loss on derivative contracts, but guidance for 2026 still calls for 14.6–15.6M silver‑equivalent ounces at consolidated all‑in sustaining costs of $27–$28 per silver ounce.
Endeavour Silver Corp. reported sharply stronger results for Q1 2026, driven by record production and higher metal prices. Revenue reached $209.7 million, up 230% from Q1 2025, while net earnings swung to a $64.9 million profit from a $32.9 million loss.
Silver equivalent production rose 78% to 3,341,943 ounces, supported by contributions from the new Terronera and Kolpa mines and the sale of lead, zinc and copper. Mine operating earnings increased to $93.5 million, and EBITDA reached $112.6 million, reflecting much higher volumes and realized prices.
Operating costs rose as the portfolio shifted. Cash costs per payable silver ounce climbed to $22.54 and all-in sustaining costs to $37.03, partly from higher royalties and special mining duties. Even with these increases, the company ended the quarter with $231.8 million in cash and working capital of $173.4 million, providing a solid financial position.
Endeavour Silver Corp. describes strong 2025 growth, major project milestones and governance plans ahead of its June 2, 2026 annual meeting in Vancouver. Shareholders will receive the 2025 audited financial statements, vote on setting the board at eight directors, elect directors and re-appoint KPMG as auditor. The company highlights a ~45% production increase to 11.2 million silver equivalent ounces in 2025, driven by acquiring the Kolpa mine in Peru and achieving commercial production at Terronera in Mexico, while divesting the Bolañitos mine and issuing convertible debt to support its balance sheet. Endeavour is advancing the large Pitarrilla silver project toward a 2026 feasibility study, targeting a construction decision in early 2027, and guides 2026 output of 8.3–8.9 million ounces of silver and 46,000–48,000 ounces of gold, or 14.6–15.6 million silver equivalent ounces. The filing also details extensive board skills, committee structures, independence, diversity metrics, safety and sustainability oversight, and use of notice-and-access for distributing meeting materials.
Endeavour Silver Corp. filed an Amendment No. 1 to its Annual Report on Form 40-F/A to attach an Amended Annual Information Form dated April 10, 2026, correcting typographical errors in the Silver-Lead-Zinc Indicated Resources table so it aligns with the applicable technical report. The amendment otherwise leaves the original Annual Report unchanged.
The filing confirms 262,323,863 common shares outstanding as of December 31, 2025, updates the exhibit index (including consents and new CEO/CFO certifications under Rule 13a-14(a)), and attaches previously filed audited financial statements and MD&A by reference.
Endeavour Silver Corp. reported strong operational results for Q1 2026, producing 1,875,375 ounces of silver and 11,740 ounces of gold, equal to 3.34 million silver-equivalent ounces. Silver production rose 56% and gold 41% from Q1 2025, driven mainly by new output from Kolpa in Peru and Terronera in Mexico, partly offset by the sale of the Bolañitos mine.
Terronera’s ramp-up stayed on plan, with improving metal recoveries through the quarter, while Guanaceví saw lower silver output due to weaker grades and a brief transformer-related shutdown. Kolpa expanded processing capacity with new crushers and a larger ball mill, targeting 2,500 tonnes per day in coming quarters despite heavy rainfall and industry-wide labour tightness.
Endeavour Silver Corp. filed its annual report on Form 40-F reporting 262,323,863 common shares outstanding as of December 31, 2025 and incorporated its AIF, audited financial statements and MD&A by reference. Management and KPMG concluded internal control over financial reporting was effective as of December 31, 2025. The Company disclosed it acquired Compañia Minera Kolpa S.A. in 2025 and that that subsidiary represented 19% of total assets, 28% of net assets, 24% of total revenues and (12%) of net income (loss) in the consolidated results; Kolpa's controls were excluded from management's assessment. All audit work was performed by KPMG LLP.
Endeavour Silver Corp. filed a Form 6-K to notify investors of its upcoming Annual General Meeting of security holders. The record date for notice, voting, and beneficial ownership determination is April 10, 2026, and the meeting will be held on June 2, 2026 in Vancouver.
The company will use notice-and-access for both registered and beneficial holders, and will not send proxy materials directly to non-objecting beneficial owners or pay for delivery to objecting beneficial owners.
Endeavour Silver Corp. filed a report highlighting several leadership changes as it advances a new phase of growth. The company, a mid-tier silver producer with three operating mines in Mexico and Peru, is strengthening both its board and senior management team.
The board appointed George Paspalas, an executive with over 40 years of international mining leadership, effective March 1, 2026. He brings experience in developing and operating precious and base metal mines across multiple regions.
On the management side, Chief Operating Officer Don Gray will retire effective April 30, 2026, after leading the Terronera project from exploration toward operations and helping shape Pitarrilla as the company’s next mine. Luis Castro, previously Senior Vice President, Exploration and a long-time executive since 2004, became Chief Operating Officer effective March 1, 2026. In addition, Gord Bussieres was appointed Vice President, Projects, bringing more than 40 years of project development and technical oversight experience to guide Endeavour’s development portfolio through feasibility and construction.
Endeavour Silver Corp. reported much higher 2025 scale but a sizable loss as it transformed its asset base. Revenue rose to $467.5 million, up 115% from 2024, driven by the Kolpa acquisition, first commercial production at Terronera and much higher silver and gold prices.
Silver-equivalent production increased 48% to 11.2 million ounces, with Kolpa adding silver and base metals and Terronera contributing high-grade silver-gold from October. However, higher operating costs, ramp-up spending and non-cash items weighed on earnings. The company posted a net loss of $119.1 million, mainly due to $126.2 million in derivative revaluation losses and higher finance charges tied to early repayment of its Terronera debt facility.
Endeavour strengthened its balance sheet with a $350 million 0.25% convertible note issue and ended 2025 with working capital of $146.4 million. For 2026, management guides to 14.6–15.6 million silver-equivalent ounces from Terronera, Guanaceví and Kolpa, consolidated cash costs of $12–13 per silver ounce and total capital spending of $157.8 million, including major investments at Pitarrilla.
Endeavour Silver reported strong growth in 2025 but a larger net loss. Silver equivalent production rose to 11.2 million ounces, up 48% from 2024, and revenue reached $467.5 million, driven by higher metal prices and contributions from the new Terronera mine and the acquired Kolpa mine.
Despite this, the company recorded a net loss of $119.1 million versus a $31.5 million loss in 2024, mainly due to $126.2 million of losses on derivative contracts, higher finance costs and increased operating costs. All-in sustaining costs climbed to $31.52 per silver ounce, reflecting ramp-up spending at Terronera and higher corporate costs.
Endeavour strengthened its asset base and liquidity, declaring commercial production at Terronera, completing the Kolpa acquisition, selling the Bolañitos mine for cash, shares and contingent payments, and issuing $350 million of convertible notes to repay most third-party debt and advance the Pitarrilla project. Year-end cash was $215.4 million, and management noted a brief, security-related pause at Terronera in early 2026 before operations returned to normal.
