Aya Gold & Silver Inc. (TSX: AYA) (NASDAQ: AYA) is pleased to report new high-grade drill exploration results at the Boumadine Project from its ongoing infill drill program in the Kingdom of Morocco. These results confirm strong high-grade continuity along the Boumadine Main Trend and support the potential for continued resource growth.

Highlights¹

Boumadine Main Trend (5.4km)

• Multiple additional high-grade intercepts:
  • BOU-DD26-848 intercepted 392 grams per tonne silver equivalent over 24.3 metres (0.61 g/t gold, 239 g/t silver, 2.6% zinc, and 1.9% lead, including 776 g/t AgEq over 10.0m (1.08 g/t Au, 488 g/t Ag, 5.2% Zn, and 3.9% Pb).
  • BOU-DD26-883 intercepted 593 g/t AgEq over 15.2m (1.05 g/t Au, 319 g/t Ag, 5.3% Zn and 3.5% Pb), including 1,038 g/t AgEq over 4.2m (1.81 g/t Au, 586g/t Ag, 8.1% Zn and 6.2% Pb).
  • BOU-DD26-0950 intercepted 299 g/t AgEq over 15.1m (1.70 g/t Au, 98 g/t Ag, 1.7% Zn and 0.6% Pb).
  • BOU-DD26-861 intercepted 1,030 g/t AgEq over 4.1m (1.06 g/t Au, 794 g/t Ag, 4.2% Zn, and 1.8% Pb) including 2,827 g/t AgEq over 1.0m (1.90 g/t Au, 2,477g/t Ag, 3.4% Zn and 3.2% Pb).
  • BOU-DD26-834 intercepted 696 g/t AgEq over 5.7m (2.70 g/t Au, 342 g/t Ag, 3.8% Zn and 1.3% Pb) and 277 g/t AgEq over 6.9m (0.56 g/t Au, 151g/t Ag, 2.1% Zn and 1.4% Pb).
• Exploration Update:
  • 145,719m drilled at Boumadine year-to-date.
  • 38.6% of the 360,000m infill program, to be carried out over 2026 and 2027, has been completed.

“Today’s high-grade results continue to demonstrate the continuity, width and potential at Boumadine,” said Benoit La Salle, President & CEO. “With over 145,000 metres drilled year-to-date and 14 drills currently turning, we are aggressively advancing the 2026–2027 infill and expansion program ahead of the updated Feasibility Study expected next year.”

1. Ag equivalent is based on a silver price of US$30/oz with a process recovery of 96%, a gold price of US$2,800/oz with a process recovery of 96%, a zinc price of US$1.20/lb with a process recovery of 75%, a lead price of US$1.00/lb with a process recovery of 82%, and a copper price of US$4.60/lb with a process recovery of 75% resulting in the following ratios: 1g/t Au: 89.7g/t Ag; 1% Cu: 78.6 g/t Ag; 1% Pb: 18.7 g/t Ag; and 1% Zn: 20.4 g/t Ag.
2. True width remains undetermined at this stage; all values are uncut.

2026 Exploration Results

This year, 406 diamond drill holes, totaling 145,719m have been completed at Boumadine (Figure 1 and Appendix 2). Drilling was done on strike along the Main Trend, Tizi and Imariren. All results have been received for drill holes up to BOU-DD26-1028 (Table 1, Figure 2, Figure 3 and Appendix 1).

Today’s results, including BOU-DD26-848 and BOU-DD26-883, confirm the high-grade nature and continuity of the Boumadine Main Trend, which remains open in all directions.

Mineralization within the Boumadine Main Trend measures up to 4m wide (locally reaching over a 10m width) and is 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 Imariren share the same characteristics except for their N000 orientation.

Next Steps

Infill drilling, following the latest positive preliminary economic assessment, will be ongoing for the next 15 months with a drill program of approximately 360,000m planned.

Significant potential exists to expand the Boumadine Main Trend (currently 5.4 km), the Tizi Zone (2.0 km) and the Imariren Zone (1.2 km), with all three trends open in all directions. Follow-up drilling is also planned on the 8 km Asirem trend for later this year.

Most drilling will continue to focus on the Main Trend, Imariren and Tizi to extend known mineralization along strike and at depth, while infilling key areas to advance the Project toward a Feasibility Study. The balance of the 2026 program (~20,000m) will target Asirem follow-up and greenfield exploration, testing geological hypotheses and targets generated over the past four years. Ongoing geological work will guide additional development priorities.

Technical Information

Aya has implemented a quality control program to comply with best practices in sampling and analysis of drill core and RC chips. For core drilling, all individual samples represent approximately one metre in length of core, which is halved. Half of the core is kept on site for reference, and its counterpart is sent for preparation and assaying to African Laboratory for Mining and Environment in Marrakech, Morocco. For drilling using RC, all individual samples represent 1.0m in length and a representative portion is kept for every metre in some chip trays stored on site. A split samples representing 1/16th, ranging from 2 to 4 kilogram is sent for preparation and assaying to African Laboratory for Mining and Environment in Marrakech, Morocco.

All samples are analyzed for silver, copper, iron, lead, zinc, tin, and molybdenum using Aqua regia and finished by atomic absorption spectroscopy. Samples grading above 200 g/t Ag are reanalyzed using fire assaying. Gold is assayed by fire assaying. Standards of different grades and blanks were inserted every 20 samples in addition to the standards, blanks and pulp duplicate inserted by Afrilab.
