Agnico Eagle Provides An Update On 2025 Exploration Results And 2026 Exploration Plans – Year Over Year Mineral Reserves Increase 2% To 55.4 MOZ; Indicated Mineral Resources Increase 10% To 47.1 Moz And Inferred Mineral Resources Increase 15% to 41.8% MOZ
Press Release
TORONTO, Feb. 12, 2026 – Agnico Eagle Mines Limited (NYSE:AEM) (TSX:AEM) (“Agnico Eagle” or the “Company”) is pleased to provide an update on year-end 2025 mineral reserves and mineral resources, exploration activities at mine sites and select advanced projects in 2025, and the Company’s exploration plans and guidance for 2026. The Company’s exploration focus remains on extending mine life at existing operations, testing near-mine opportunities and advancing key value driver projects.
“I would like to congratulate our exploration team for their performance in 2025 in terms of safety, productivity and cost control with an average of 120 diamond drill rigs in operation drilling 1.4 million metres of core. The exploration program continued to yield exciting results at our mines and key pipeline projects, which drove an increase in our mineral reserves and in our measured, indicated and inferred mineral resources primarily from additions at Detour Lake, Odyssey and Hope Bay,” said Guy Gosselin, Agnico Eagle’s Executive Vice-President, Exploration. “The success of our 2025 exploration program reinforces our view that we have built the strongest project pipeline in the Company’s history, with exceptional exploration upside—arguably the best in the gold mining sector,” added Mr. Gosselin.
Highlights from 2025 include:
- Gold mineral reserves increase to record level – Year-end 2025 gold mineral reserves increased by 2.1% to 55.4 million ounces of gold (1,330 million tonnes grading 1.30 grams per tonne (“g/t”) gold). The year-over-year increase in mineral reserves is due to a combination of mineral reserve replacement from operating mines and the initial declaration of mineral reserves at the Marban deposit in Malartic. At year-end 2025, measured and indicated mineral resources were up 9.6% to 47.1 million ounces (1,200 million tonnes grading 1.22 g/t gold) and inferred mineral resources were up 15.5% to 41.8 million ounces (522 million tonnes grading 2.49 g/t gold)
- Detour Lake – The Company’s exploration program continued to de-risk the Detour Lake underground project in the western plunge of the main orebody hosting the producing open pits. Conversion drilling further increased underground indicated mineral resources below the resources open pit to 3.47 million ounces of gold (52.9 million tonnes grading 2.04 g/t gold) at year-end while exploration drilling below and to the west of the open pit increased underground inferred mineral resources to 3.88 million ounces of gold (59.6 million tonnes grading 2.03 g/t gold) at year-end
- Odyssey – Inferred mineral resources increased by 62% (2.8 million ounces of gold) year over year at the East Gouldie deposit to 7.4 million ounces of gold (94.3 million tonnes grading 2.43 g/t gold), including the Eclipse zone. The Odyssey mine now hosts a total of 6.03 million ounces of gold in proven and probable mineral reserves (59.7 million tonnes grading 3.14 g/t gold), 3.4 million ounces of gold in measured and indicated mineral resources (57.8 million tonnes grading 1.85 g/t gold) and 12.7 million ounces of gold in inferred mineral resources (177.7 million tonnes grading 2.21 g/t gold)
- Marban – As part of the “fill-the-mill” strategy at Canadian Malartic, a technical evaluation was completed at the Marban deposit during the fourth quarter of 2025 that updated the probable mineral reserves to 1.58 million ounces of gold (51.6 million tonnes grading 0.95 g/t gold) at December 31, 2025. This is the first declaration of mineral reserves by the Company at Marban since the acquisition of O3 Mining Inc., which includes the Marban deposit, in March 2025
- Hope Bay – Exploration drilling in 2025 totalled 131,208 metres and focused mainly on mineral resource expansion of the Madrid deposit following the exploration success at the Patch 7 zone during 2024 and 2025. The Patch 7 zone now hosts 1.0 million ounces of gold in indicated mineral resources (4.5 million tonnes grading 6.77 g/t gold) while inferred mineral resources have increased by 123% to 1.7 million ounces of gold (8.0 million tonnes grading 6.57 g/t gold)
- Exploration guidance – In 2026, the Company’s total exploration expenditures and project expenses are expected to be between $565 million and $635 million, with a mid-point of $600 million. This includes approximately $384 million for capitalized and expensed exploration, and approximately $216 million for advanced exploration project expenses, studies, and other corporate development activities. The Company’s exploration focus remains on extending mine life at existing operations, testing near-mine opportunities and advancing key value driver projects. Priorities for 2026 include continued drilling of the Detour Lake underground project, assessing the full potential of the Canadian Malartic property, supporting regional synergies in Abitibi and exploring Hope Bay
GOLD MINERAL RESERVES
As at December 31, 2025, the Company’s proven and probable mineral reserve estimate totalled 55.4 million ounces of gold (1,330 million tonnes grading 1.30 g/t gold). This represents a 2.1% (1.16 million ounce) increase in contained ounces of gold compared to the proven and probable mineral reserve estimate of 54.3 million ounces of gold (1,277 million tonnes grading 1.32 g/t gold) at year-end 2024 (see the Company’s news release dated February 13, 2025 for details regarding the Company’s December 31, 2024 proven and probable mineral reserve estimate).
The increase in mineral reserves at December 31, 2025 is the result of the replacement of 3.0 million ounces of gold mined from operating assets, including Odyssey, Meliadine, LaRonde, Goldex, Fosterville and Macassa, combined with the acquisition of the Marban project, where initial mineral reserves were declared at year-end 2025.
A technical evaluation of the Marban deposit completed during the fourth quarter of 2025 resulted in new probable mineral reserves of 1.58 million ounces of gold (51.6 million tonnes grading 0.95 g/t gold) at December 31, 2025. The progress in mineral reserve development at Marban is the result of efforts by the Company to leverage regional synergies following the recent transactions to consolidate the Malartic camp at Canadian Malartic and advance the “fill-the-mill” strategy.
Mineral reserves were calculated using a gold price of $1,600 per ounce for most operating assets, with exceptions that include Detour Lake open pit using $1,500 per ounce; Amaruq and Pinos Altos using $2,000 per ounce; and variable assumptions for some other pipeline projects, including Marban and Wasamac using $1,650 per ounce. For detailed mineral reserves and mineral resources (“MRMR”) data, including the economic parameters used to estimate the mineral reserves and mineral resources and by-product silver, copper and zinc at mines and advanced projects, see “Detailed Mineral Reserves and Mineral Resources Data (as at December 31, 2025)” and “Assumptions used for the December 31, 2025 mineral reserve and mineral resource estimates reported by the Company” below.
The ore extracted from the Company’s mines in 2025 contained 3.74 million ounces of in-situ gold (65.5 million tonnes grading 1.78 g/t gold).
The Company’s gold mineral reserves as at December 31, 2025 are set out in the table below, and are compared with the gold mineral reserves as at December 31, 2024. Data in this table and certain other data in this news release have been rounded to the nearest thousand and discrepancies in total amounts are due to rounding.
