"Exploration success at both Zgounder and Boumadine during 2024 has been instrumental in driving the growth of our assets, with exceptional intercepts highlighting the potential to significantly increase high-grade ounces in the near term," commented Benoit La Salle, President & CEO. "Our completion of over 150,000 meters of drilling, combined with the use of high-resolution spectral imagery and geophysics technology, have been crucial in achieving exploration success and uncovering new opportunities. By expanding our footprint with the addition of over 150 km² of ground in Morocco, we are committed to creating value for all shareholders through the drill bit and will continue this growth momentum into 2025."

Summary of Exploration Results

Zgounder Exploration

The Zgounder Mine is a volcanic Ag mineralization sediment hosted deposit, underground and open pit mine in the central Anti-Atlas mountains of Morocco. Best intercepts for 2024 are shown in Table 1.

• For the period of January to December 2024, a total of 35,469m were completed. (Figure 1)
• Infill drilling, underground and surface, on the high-grade mineralization at the main orebody confirmed the mineralization and extended underground production zones. Results include: DZG-SF-24-172 with 21.0m at 2,165 g/t Ag including 3.5m at 4,600 g/t Ag, DZG-SF-24-065 with 6.5m at 2,870 g/t Ag including 2.0m at 7,229 g/t Ag and ZG-23-54 with 7.0m at 1,846 g/t Ag including 5.0m at 2,095 g/t Ag. (Figure 2)
• Silver mineralization at depth, near the granite contact was confirmed and extended 800m along strike, with results including: ZG-SF-23-084 with 13.5m at 1,089 g/t Ag including 7.5m at 1,700 g/t Ag and 4.5m at 4,469 g/t Ag, ZG-SF-24-200 with 21.0m at 1,151 g/t Ag including 6.0m at 3,290 g/t Ag and ZG-SF-24-123 with 2.5m at 5,696 g/t Ag.
• The open pit area is a key contributor to production, reverse circulation ("RC") drilling on the area, at east of the deposit confirmed the continuity of the mineralization at south and at north. Results include: ZG-RC-24-028 with 24.0m at 986 g/t Ag including 4.0m at 4,418 g/t Ag, ZG-RC-24-228 with 20.0m at 1,356 g/t Ag including 14.0m at 1,799 g/t Ag, ZG-RC-24-277 with 17.0m at 2,425 g/t Ag including 5.0m at 6,311 g/t Ag and ZG-RC-24-082 with 16.0m at 1,155 g/t Ag including 5.0m at 2,335 g/t Ag.

Zgounder Regional Exploration

Exploration drilling focused on near-mine targets within a 2km radius around the Zgounder deposit with a total of 10,651m drilled.

• Zgounder West Target: Drilling targeted the along-strike continuity of the Zgounder deposit to the west, intercepting silver occurrences within the same sedimentary unit that hosts mineralization at the main Zgounder deposit. Assays results are still pending for this area.
• Zgounder East Target: Drilling targeted the Proterozoic sedimentary sequence beneath the Sirwa volcanic complex, which overlies the units hosting the Zgounder deposit. Drill holes reached vertical depths of up to 480m, intercepting felsic volcanic units with anomalous Ag intervals. These anomalous assay results from the Sirwa volcanic complex reveal previously undocumented potential for this unit. Follow up work will be carried in 2025.
• Zgounder South Target: Drilling tested the southern contact of the rhyolite unit bounding the main deposit to the north. The drilling intercepted sedimentary units similar to those hosting the Zgounder deposit, at the contact with the rhyolite. Anomalous Ag results were returned and follow up is expected in 2025.
• Zgounder Southeast Target: Drilling tested an area of Ag occurrence identified through previous surface grab sampling. This target is located in a geological window within a riverbed, exposing lithologies buried beneath the younger Sirwa volcanic complex. Drilling assessed a small portion of the target, and follow-up with surface mapping is planned.
• Geological mapping and prospecting, focusing on the Tirzzit and Zgounder Far East properties, both acquired late in 2023.
• A stream sediment campaign on Tirzzit, Zgounder Far East, and follow-up on previous stream sediment results from Touchkal property.
• Execution of an airborne geophysical survey over the Tirzzit project (154km²).
• Acquisition of World-View 3 hyperspectral imagery for the Tirzzit and Zgounder Far East properties, followed by ground calibration of the hyperspectral survey using samples collected from the concerning areas.

Boumadine Project

Boumadine is a large polymetallic deposit (Ag, Au, Pb, Zn) located in the Anti-Atlas Mountains, 80km south-west of the city of Errachidia. The main mineralization generally consists of 1m to 4m wide (locally reaching over a 10m width) N340- oriented massive sulphide lenses/veins sharply dipping eastward (> 70°). The massive sulphide veins (>80%) are mainly composed of pyrite, with variable proportions of sphalerite, galena, and chalcopyrite. The Tizi and Imarriren zones share the same characteristics except for their N000 orientation. Best intercepts for 2024 are shown in Table 2.

• The estimated mineral resources, as provided on April 16 2024, consist of an Inferred Mineral Resource of 23.6Mt at 85 g/t Ag, 2.62 g/t Au, 2.32% Zn and 0.84% Pb containing an estimated 64.7Moz of Ag, 1.98Moz of Au, 546kt of Zn and 198kt of Pb and an Indicated Mineral Resource of 2.0Mt at 113 g/t Ag, 2.51 g/t Au, 4.32% Zn and 1.07% Pb containing an estimated 7.4Moz of Ag, 165koz of Au, 88kt of Zn and 22kt of Pb.
• In 2024, 219 drillholes totalling 107,683m were completed and the Boumadine Main zone was extended to 5.4km and remain open in all directions. (Figure 3)
• Silver-cupper rich mineralization was intercepted in east-west barite vein with result: BOU-DD24-329 intercepted 2,110 g/t AgEq over 1.9m (0.03 g/t Au, 1,937 g/t Ag, 0.16% Zn, 0.17% Pb and 1.66% Cu).
• Polymetallic mineralization on the Tizi zone was extended to 2.0km in length. Significant intercepts include: 1,021 g/t AgEq over 3.0m (11.48 g/t Au, 89 g/t Ag, 0.78% Zn, 0.15% Pb and 0.24% Cu, BOU-DD24-306) and 445 g/t AgEq over 13.7m (4.9 g/t Au, 42 g/t Ag, 0.35% Zn, 0.37% Pb and 0.06% Cu, BOU-DD24-306)
• High grade gold at Imarriren zone below the known mineralization with result: BOU-DD24-284 intercepted 1,317 g/t AgEq over 1.9m (15.7 g/t Au, 91 g/t Ag, 0.1% Zn, 0.1% Pb and 0.2% Cu).
• High grade mineralization was intercepted in the Main Trend. Significant intercepts include: 763 g/t AgEq over 3m (1.5 g/t Au, 311 g/t Ag, 4.4% Zn, 1.8% Pb and 0.04% Cu, BOU-DD23-223) and 991 g/t AgEq over 17.6m (2.6 g/t Au, 247 g/t Ag, 7.7% Zn, 1.2% Pb and 0.3% Cu, BOU-DD23-230).
• 15 additional exploration permits, expanding the Boumadine exploration footprint to 252.5km². (Figure 4)
• Completion of a satellite mapping and spectral study on Boumadine using WorldView-3 data over 674km². Identification of numerous clay alteration halos similar to Boumadine.
• Completion of an extensive helicopter-borne MobileMT electromagnetic and magnetic survey that covers an area of 1,266 km². Identification of multiple potentially parallel, on-trend conductive anomalies like known conductors identified at Boumadine Main Trend. Very large, potential conductive anomalies occurring 5km west of Boumadine, of similar orientation and stronger intensity than the Boumadine Main Trend conductor. This very large system also includes strong potential conductors occurring in an east-west direction. Continuation of the Boumadine south main trend anomaly, and series of new N340 and north-south oriented potential conductive anomalies.
• Over 27,000 assays are still pending at Boumadine.

Quality Assurance

For core drilling, all individual samples represent approximately one meter in length of core, which is halved. Half of the core is kept on site for reference. Aya has implemented a quality control program to comply with best practices in sampling and analysis of drill core. Drill core samples were transported in sealed bags for analysis at Afrilab laboratory in Marrakech. Standards of different grades and blanks were inserted every 20 samples in addition to the standards, blanks and pulp duplicate inserted by Afrilab.

David Lalonde, B.Sc. P. Geo, Vice-President Exploration, is Aya Gold & Silver's Qualified Person and has reviewed this press release for accuracy and compliance with National Instrument 43-101.
