Aya Gold & Silver Inc. (TSX: AYA) (OTCQX: AYASF) is pleased to announce new high-grade drill exploration results from its 2024 – 2025 program at Boumadine in the Kingdom of Morocco. Today’s results extend the Imariren mineralized trend by 400 meters, confirming high-grade continuity along the Boumadine Main Trend. In addition, Aya is pleased to announce the addition of four (4) new permits to the west, expanding the Boumadine exploration footprint by 15.7% to over 314.5 square kilometers.

1. All intersections are in core lengths. Ag equivalent is based on a silver price of US$24/oz with a process recovery of 89%, a gold price of US$2,200/oz with a process recovery of 85%, a zinc price of US$1.20/lb with a process recovery of 72%, a lead price of US$1.00/lb with a process recovery of 85%, and a copper price of US$4.00/lb with a process recovery of 75% resulting in the following ratios: 1g/t Au: 77.9 g/t Ag; 1% Cu: 85.4 g/t Ag; 1% Pb: 24.2 g/t Ag; and 1% Zn: 24.6 g/t Ag.

Today’s high-grade drill exploration results highlight the scale and continuity of Boumadine and mark a significant step in unlocking its full potential,” said Benoit La Salle, President & CEO. “High-grade holes BOU-DD25-513 and BOU-DD25-516 confirm strong continuity of the Boumadine Main Trend at depth—this is the backbone of the deposit and will form the foundation of our upcoming PEA. Drilling continues to expand the footprint, with extensions to the north at Imariren and new intercepts at depth on the parallel Tizi structure. Boumadine continues to demonstrate the potential to become a large-scale, high-grade deposit with mineralization open in all directions. With four new permits secured, a consolidated 314 km² land package, and exploration rights over 600 km², we are in a strong position to continue creating value.”

2025 Exploration Results 

This year, 140 diamond drill holes, 31 reverse circulation holes and 11 multi-purpose drill holes totaling 72,044m have been completed at Boumadine (Figure 1, Figure 2 and Appendix 2). Drilling was conducted on strike along the Main Trend (North Zones), Tizi, Imariren as well as on some regional targets. The majority of results have been received for drill holes up to BOU-DD25-530 (Table 1, Figure 3, and Appendix 1).

Results received so far in 2025, including hole BOU-DD24-465, BOU-DD25-513 and BOU-DD25-516, confirm the high-grade continuity of the Main Trend, which remains open in all directions. Today’s results, with BOU-DD25-504, BOU-DD25-509 and BOU-DD25-511, also confirm the continuity of the Imariren Zone and extend Tizi mineralization to 0.7km. The Imariren Zone also remains open in all directions.

Hole BOU-MP24-015 returned high-grade silver results including 774 g/t Ag over 1.6m in an east-west structure.

The main mineralization generally measures 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 Imariren share the same characteristics except for their N000 orientation.

Figures 4 shows the newly acquired permits expanding the Boumadine exploration footprint by 15.7% to over 314.5 km².

Next Steps

Significant upside potential exists to expand the Boumadine Main Trend, which currently extends 5.4km and remains open in all directions. Currently, the Corporation has mobilized 6 drill rigs to complete the 100,000m to 140,000m drilling program. Half of the drilling will focus along the Main Trend and Tizi to continue extending the known mineralization trend along strike and at depth and to infill known areas advancing the project towards a preliminary economic assessment. The remaining 50% will focus on greenfield exploration designed to test geological hypotheses and drill targets generated from the past three years of work. The results from ongoing geology work will determine additional development work.

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 meter 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 meter in some chip trays stored on site. A split sample representing 1/16^th, ranging from 2 to 4 kilograms 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.
