CEO.CA Chairman's Briefing

MONTREAL, May 13, 2024 (GLOBE NEWSWIRE) -- Aya Gold & Silver Inc. (TSX: AYA; OTCQX: AYASF) (“Aya” or the “Corporation”) is pleased to announce new high-grade drill exploration results from its 2024 program of 120,000 meters (“m”) at Boumadine in the Kingdom of Morocco. Today’s results extend the main mineralized trend by 800m and continues to demonstrate continuity of the Boumadine Main Zone, which remains open in all directions. The Corporation also reports it has secured the right to 7 additional exploration permits, expanding the Boumadine exploration footprint to over 198 square kilometers (“km²”).

• Key Highlights¹
  • Extension of Boumadine strike length to 5 kilometers (“km”):
    • BOU-DD23-265 intersected 1,355 grams per tonne (“g/t”) silver equivalent (“AgEq”) over 3.1 m (16.25 g/t gold (“Au”), 86 g/t silver (“Ag”), 0.1% zinc (“Zn”), 0.1% lead (“Pb”) and 0.1% copper (“Cu”) and 442 g/t AgEq over 8.0m (4.51 g/t Au, 58 g/t Ag, 0.3% Zn, 0.2% Pb and 0.2% Cu)
    • BOU-DD24-292 intersected 354 g/t AgEq over 2.9m (4.06 g/t Au, 27 g/t Ag, 0.4% Zn, 0.1% Pb and 0.03% Cu)
    • BOU-DD24-284 intersected 1,317 g/t AgEq over 1.9m (15.70 g/t Au, 91 g/t Ag, 0.05% Zn, 0.1% Pb and 0.2% Cu)
  • Extension of the Tizi strike length to 1.6km:
    • BOU-DD24-310 intersected 445 g/t AgEq over 13.7m (4.90 g/t Au, 42 g/t Ag, 0.3% Zn, 0.4% Pb and 0.1% Cu), including 1.6m at 1,988 g/t AgEq and 1.5m at 813 g/t AgEq
    • BOU-DD24-306 intersected 1,021 g/t AgEq over 3.0m (11.48 g/t Au, 89 g/t Ag, 0.8% Zn, 0.2% Pb and 0.2% Cu) including 1.5m at 1,755 g/t AgEq
  • New style of mineralization with very high silver grade:
    • BOU-DD24-310 intersected 7,820 g/t Ag over 1.0m
  • Secured 7 new exploration permits totaling 56.9 km² at Boumadine (Figure 1)
    

“Today’s high-grade drill results including BOU-DD23-265 in the north of the Main Trend extend the Boumadine footprint to 5km, and BOU-DD23-310 at Tizi confirms the potential to increase the resource,” said Benoit La Salle, President & CEO. “We are excited to expand our presence further at Boumadine through the strategic addition of 7 new permits, as part of our ongoing strategy to grow our land package and underscoring our confidence in the region's mineral potential. With an area of almost 200km² in what we consider to be a generational asset and a potential district, we are in position to deliver value for all stakeholders.”

2024 Exploration Results

This year, 60 diamond drill holes (“DDH”) for 27,122m have been completed at Boumadine (Figure 2 and Appendix 2). Drilling was conducted on strike along the Main Trend (North Zones), Tizi and North-West Zones. The majority of results have been received for drill holes up to BOU-DD23-310 (Table 1, Figure 4, and Appendix 1).

Results received since January 2024 including hole BOU-DD24-292 confirm the high-grade continuity of the Main Trend and extend the mineralized strike length to 5km. The Main Trend remains open in all directions. Today’s results also significantly extend the strike length of the Tizi Zone from 600m to 1.6km. The Tizi Zone also remains open in all directions.

Hole BOU-DD24-310 returned high-grade silver results including 7,820 g/t Ag over 1.0m in a small East-West structure. This new structure is a brecciated carbonate-quartz-galena vein with low temperature texture (blades, crustiform and colloform). Because the drilling was planned for Tizi, the East-West structure was intersected at a very low core-angle. True thickness is still unknown but is probably less than 0.2m. This type of vein will be better targeted with a specific “East-West” drill program.

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. Tizi and Imarriren share the same characteristics except for their N000 orientation. Figure 3 presents the results of the Boumadine Main Zone on a longitudinal section along the deposit.

Next Steps

Significant upside potential exists to expand the Boumadine Main Trend, which currently extends 5.0km and remains open in all directions. Currently, the Corporation has mobilized seven drill rigs to complete the 120,000m drilling program. Half of the program will test the continuation of the known trend and infill. The remaining 50% will focus on geological targets generated by 2023 work and will be informed by the ongoing hyperspectral and high-resolution geophysical surveys. Hyperspectral and the geophysical surveys began in early 2024 and results are expected in late Q2-2024. The results from ongoing geology work will determine additional development work.
