Endeavour Silver Produces 1,875,375 Oz Silver and 11,740 Oz Gold, for a total of 3.3 Million Silver Equivalent Oz in Q1 2026
VANCOUVER, British Columbia, April 08, 2026 (GLOBE NEWSWIRE) -- Endeavour Silver Corp. ("Endeavour" or the "Company") (NYSE:EXK, TSX:EDR) reports first quarter 2026 production of 1,875,375 silver ounces ("oz"), 11,740 gold oz, and in combination with base metals, a silver equivalent (1) ("AgEq") production of 3.3 million oz. All dollar amounts are in US dollars ($).
"We are pleased to report robust production for the first quarter of 2026, highlighted by steady performance at Terronera, which delivered improved grades and recoveries without any significant shutdowns," commented Dan Dickson, Chief Executive Officer. "Guanaceví continued to perform consistently, and Kolpa not only enhanced its processing capabilities despite adverse weather but is now set to increase production to 2,500 tonnes per day for the quarters ahead. Our team's dedication and adaptability have been instrumental in navigating market conditions and operational transitions, laying a solid foundation for the rest of the year."
Q1 2026 Production Overview
- Terronera Ramp up and Optimization: Throughput was consistent with plan, while metal recoveries improved through continued process refinement. March recoveries were in line with management targets and are expected to continue going forward.
- Guanaceví Shows Resilience: Due to lower silver grades and lower plant throughput than planned, silver production was slightly below plan with gold grades and recoveries in line with plan.
- Kolpa Plant Expansion: During March 2026, new crushers and a new 14´x 24´ ball mill were commissioned to enable throughput of 2,500 tonnes per day (tpd) in the upcoming quarters. A high intensity of rainfall during the quarter increased moisture content of processed material and caused limited power outages, slowing down crushing and plant operations and reducing throughput and metal production, with continued stable grades and recoveries.
- Bolañitos Sale Finalized: On January 15, 2026 the Company completed the sale of the Bolañitos silver and gold mine (see news release from November 24, 2025 here). The first 15 days of 2026, mine production are included in the Company's production results.
- Metal Sales and Inventories: Sold 1,642,220 silver ounces and 10,942 gold ounces during the first quarter. A total of 419,699 silver ounces and 1,405 gold ounces of bullion inventory and 72,048 silver ounces and 575 gold ounces in concentrate inventory were held as at March 31, 2026. At the end of the first quarter, silver and gold prices experienced downward pressure and management decided to hold bullion inventory temporarily.
Q1 2026 Mine Operations
Consolidated silver production was 1,875,375 oz in Q1 2026, slightly below plan, and 56% higher than 1,205,793 oz produced in Q1 2025. Higher production is attributed to the addition of 530,118 oz from Kolpa and 533,301 oz from Terronera, partially offset by the sale of Bolañitos. Silver production at Guanaceví was 22% lower than Q1 2025, predominantly due to 18% lower silver grades and 7% lower throughput.
Consolidated gold production was 11,740 oz in Q1 2026, 41% higher than 8,338 oz produced in Q1 2025. Higher production is primarily attributable to the addition of 8,478 oz from Terronera, partially offset by the sale of Bolañitos. Gold production at Guanacevi was 31% lower than Q1 2025, predominantly due to the 22% lower gold grade and 7% lower throughput.
Terronera's production was in line with plan and is expected to increase during the year as mine development accesses higher-grade areas by Q3 2026. The February security events in Jalisco had minimal impact at Terronera. Operations were paused for three days to ensure safety of our employees, with a minor impact on overall throughput. Terronera recoveries averaged 84.0% for silver and 72.7% for gold, both slightly below Q1 plan. During the first quarter, plant management refined processes to improve recoveries which gradually improved throughout the period. In March, recoveries were in line with plan and are expected to further improve with additional optimization. Ore grades of 113 grams per tonne (g/t) for silver and 2.07 g/t of gold were in line with plan for the quarter.
Guanaceví throughput was 7% lower than Q1 2025 and 7% lower than plan, primarily due to a transformer failure which caused a 2.5-day shutdown of the tailing filters. Supplies of local third-party mill feed continued to supplement Guanaceví production, amounting to 27% of quarterly throughput.
In Q1 2026, Kolpa's throughput was 171,727 tonnes producing 530,118 oz of silver. The material processed had average grades of 106 g/t silver and 3.05% lead, 1.97% zinc and 0.20% copper. During March 2026, new crushers and a new 14' x 24' ball mill were commissioned and will enable throughput of 2,500 tpd in the upcoming quarters. Huancavelica, the region of Peru where Kolpa is located, experienced an unusually high intensity of rainfall in Q1 2026, attributing to a delay in ramping up the plant expansion and leading to increased water treatment and higher humidity of material processed. Additionally, with increased metal prices, increased mining and construction activities in Peru has resulted in labour shortages throughout the mining industry. Despite this, the plant operated efficiently and is on schedule to increase throughput during Q2 2026.
