Key Highlights
Article content
- Updated LOM Plan
- Average Annual Silver Production: 6 million ounces (“Moz”) of silver (“Ag”) over the next 11 years, totaling ~66 Moz Ag over the LOM.
- Average LOM Operating Costs: Cash cost1 of $16.26/oz and $69.47 per tonne of ore (“t”) processed over the LOM.
- Sustaining Capital Expenditures: $71 million (“M”) over the LOM.
- Extended LOM to 2036: The updated mine plan is based on a capital-efficient open-pit strategy, with targeted underground zones, extending the mine life to 2036 and supported by net reserve growth.
- Net Reserve and Resource Growth
- P&P Reserves: 73 Moz Ag at 145 g/t (15.7 million tonnes (“Mt”)), a 4% increase in Ag ounces from the prior estimate, net of depletion, with reserves estimated using a silver price assumption of $26 per oz (“oz”).
- Reserve Replacement: P&P Reserves include additions of 13 Moz, exceeding the 11 Moz mined since the prior estimate (December 31, 2021), resulting in a reserve-replacement ratio of 120%.
- Open-Pit Weighted Reserves: Reserves are now largely open-pit (78%), with underground reserves (22%) focused on deeper levels.
- Measured & Indicated Resources (“M&I Resources”)2: 100 Moz Ag at 165 g/t Ag (18.9 Mt), a 5% increase in total Ag ounces from the prior estimate, net of depletion, with resources estimated using a silver price assumption of $28/oz.
- Stronger Geological Model Supported by Extensive Drilling
- The updated interpretation incorporates ~275,000 metres (“m”) of drilling since 2021 (64% of all drilling on the property), and structural studies of the deposit, enhancing confidence in the resource model and the mine plan.

Article content
“The updated mine plan supports annual silver production of ~6 Moz over the next 11 years, with a disciplined, capital-efficient, open-pit focused strategy extending mine life to 2036,” said Benoit La Salle, President & CEO.
Article content
“The update reinforces the resource model and strength of the project. Extensive drilling, operational experience, and a deeper geological understanding have improved the reliability of the model and mine plan. We are pleased that exploration over the past several years has replenished reserves and contributed to net growth, providing a solid foundation to advance execution. The reserve estimate includes mining dilution in line with current operations.
Article content
“With the ramp-up phase complete and a favorable market landscape, we are well positioned to execute the plan and support Aya’s future growth. Zgounder remains open to the west, offering potential for long-term mine-life extension, and we will continue to evaluate opportunities for optimization and production increases as part of our commitment to long-term value creation.”

Mineral Resources
Article content
The June 30, 2025 Mineral Resource Estimate was prepared by RSC using Leapfrog Geo. Geological modelling was conducted using the interval selection and the vein system tools to create a geological model, consisting of a lithological model and a simplified structural model. Estimation domains using indicator radial basis function (RBF) interpolants were constrained at three different modelling grade cut-offs: 10.0 g/t Ag for low-grade mineralization (LG10), 60.0 g/t Ag for medium grade (MG60) and 150.0 g/t Ag for high grade (HG150). Grades were interpolated using ordinary kriging for the LG10 and MG60 domains and residual indicator kriging (RIK) for the HG150 domain.
Article content
The open pit Mineral Resource estimates are pit-constrained and reported above a 40 g/t Ag cut-off; the out-of-pit Mineral Resource estimates are reported above a 90 g/t Ag cut-off. The Mineral Resource estimates and metal content as of June 30, 2025, are detailed in Table 1.

Notes:
Article content
- M&I Resources are inclusive of Mineral Reserves.
- Updated Technical Report Mineral Resources are reported assuming a silver price of $28/oz, and Mineral Reserves are reported assuming a silver price of $26/oz, and accounting for mine depletion until September 30th, 2025.
- December 31, 2021 Mineral Resources are reported assuming a silver price of $22.5/oz, and Mineral Reserves are reported assuming a silver price of $20/oz.
Article content
Compared with the previous estimate, the updated P&P Reserves show a net increase of approximately 2.5 Moz Ag, and the M&I Resources (inclusive of reserves) show an overall increase of 5.0 Moz, after accounting for all material mined from 2022 through Q3-2025. Open-pit Mineral Reserves have increased, while underground Reserves have decreased, reflecting Aya’s strategy to expand the open-pit operation while focusing underground mining on deeper levels. Reported grades are lower, primarily due to the integration of extensive new drilling, improved geological interpretation, and updated estimation methods better suited to the deposit’s complex ore distribution. The updated P&P Reserves also incorporate dilution assumptions informed by current mining practices and benefits from enhanced geological and structural interpretations resulting in a more accurate representation of the deposit’s geometry and grade profile.
Article content
Article content
Approximately 275,000m of drilling have been completed since the previous estimate, representing 64% of all drilling conducted on the property to date. With this extensive drilling, enhanced understanding of the resource, and an independent third-party review, the updated MRE provides a clearer and more representative view of the deposit.

Life of Mine Plan
Article content
The LOM plan for Zgounder incorporates both open-pit and underground mining, alongside the reclamation of surface stockpiles, with all the ore processed at the Zgounder mill. Based on the 2025 Mineral Reserves, the mine life is projected to run until 2036, with average production of approximately 6.2 Moz from 2026 through 2036. Key aspects of the LOM plan include:
Article content
- Mining Methods: A mix of cut-and-fill and longhole stope mining is planned though the LOM, with a gradual shift towards greater reliance on longhole mining and reduced cut-and-fill.
- Underground Sequencing: Cut-and-fill mining will continue through 2031, while longhole mining will start in 2026 and run through 2032.
- Open-Pit Mining: Open-pit mining will continue until 2036, with mining rates averaging at 45 thousand tonnes per day (“ktpd”) of material (ore and waste) until 2030, moderating to 22 ktpd until 2033, and 12-14 ktpd for the remainder of the LOM.
- Processing: The processing plant is expected to operate at a rate of 3,650 ktpd through 2026 and then at 3,850 ktpd through the end of the LOM.
- Development: A total of 8,340m of lateral development and 2,402m of vertical development are planned by 2029.
- Metallurgy: Silver recovery is estimated at 91.5%
- LOM Operating Costs: Average operating costs of $69.47/t processed for a cash cost of $16.26/oz.
- Sustaining Capital Expenditures: $71M over the LOM.
