Aya Gold & Silver Reports High-Grade Exploration Results at Boumadine, Extends Imariren Zone to 0.7km and Adds 4 New Regional Permits

MONTREAL, June 05, 2025 (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 - 2025 program at Boumadine in the Kingdom of Morocco. Today's results extend the Imariren mineralized trend by 400 meters ("m”), 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 ("km²”).

• Extension of the Imariren Strike Length to 0.7km:
  • BOU-DD25-509 intercepted 296 g/t AgEq over 9.3m (2.18 g/t Au, 62 g/t Ag, 1.5% Zn, 0.7% Pb and 0.1% Cu), including 1.6m at 897 g/t AgEq
  • BOU-DD25-504 intercepted 349 g/t AgEq over 6.6m (3.69 g/t Au, 46 g/t Ag, 0.3% Zn, 0.2% Pb and 0.05% Cu), including 1.2m at 851 g/t AgEq
  • BOU-DD25-511 intercepted 449 g/t AgEq over 4.9m (1.95 g/t Au, 270 g/t Ag, 0.6% Zn, 0.1% Pb and 0.1% Cu)
• Acquired one (1) mining licence and three (3) exploration permits totaling 42.9 km² in the Boumadine area (Figure 3).

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.”
