Aya Gold & Silver Reports High-Grade Exploration Drill Results Near Pit Depth at Zgounder

MONTREAL, June 02, 2026 (GLOBE NEWSWIRE) — Aya Gold & Silver Inc. (TSX: AYA; NASDAQ: AYA) (“Aya” or the “Corporation”) is pleased to announce high-grade silver drill results from its at-depth drill exploration program at the Zgounder Silver Mine (“Zgounder”) in the Kingdom of Morocco.

Highlights (all intersections are in core lengths)

• Intersections in the Open-Pit Area:
  • Hole ZG-RC-26-946 intercepted 1,867 grams per tonne (“g/t”) silver (“Ag”) over 6.0 metres (“m”), including 5,100 g/t Ag over 2.0m
  • Hole ZG-RC-26-942 intercepted 739 g/t Ag over 10.0m, including 1,674 g/t Ag over 4.0m
  • Hole ZG-RC-26-799 intercepted 1,160 g/t Ag over 6.0m, including 1,778 g/t Ag over 3.0m
  • Hole ZG-RC-26-943 intercepted 886 g/t Ag over 5.0m
• Intersections Near the Western Fault contact:
  • Hole YAK-26-502 intercepted 795 g/t Ag over 4.8m
  • Hole T28-26-1152 intercepted 445 g/t Ag over 7.2m
• Intersections in the Central Area:
  • Hole DZG-SF-26-740 intercepted 1,330 g/t Ag over 4.6m, including 3,680 g/t Ag over 1.2m
  • Hole DZG-SF-26-741 intercepted 1,087 g/t Ag over 5.5m, including 3,347 g/t Ag over 1.5m
  • Hole T28-26-1248 intercepted 2,176 g/t Ag over 8.4m, including 4,298 g/t Ag over 3.6m
  • Hole T28-26-1177 intercepted 1,464 g/t Ag over 4.8m, including 5,480 g/t Ag over 1.2m
• 9,250m or 30.8% of the 2026 exploration program has been drilled year to date.

“Today’s high-grade results continue to confirm the strong continuity of silver mineralization both around the open pit and within the central zone,” said Benoit La Salle, President & CEO. “Importantly, new intersections near the Western Fault continue to support the significant exploration potential to the west, where development of the exploration drift at the 1825-metre level is advancing ahead of planned drilling west of the fault in the second half of the year. In parallel, drilling along the granite contact continues to demonstrate encouraging high-grade continuity at depth.”

This release contains results from 116 holes, which include 5 surface diamond drill holes (“DDH”), 28 underground DDH, 23 reverse circulation drill hole (“RC”), 33 T28 and 27 YAK holes (T28 and YAK: percussion drilling using an air-compressed hammer). For a full summary of today’s results, refer to Appendix 1.

Technical Information

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 (“Afrilab”) in Marrakech, Morocco or to ALS Laboratory at the Zgounder Mine site. All samples are analyzed for silver, copper, iron, lead, and zinc using Aqua regia and finished by atomic absorption spectroscopy (“AAS”). Samples grading above 200 g/t Ag are reanalyzed by fire assay.

For definition drilling using RC, all individual samples represent 1.0m in length and for T28 drilling equipment, all individual samples represent 1.2m in length. Samples are assayed at either the ALS Mine laboratory or at Afrilab. All samples are analyzed for silver, copper, iron, lead, and zinc using Aqua regia and finished by AAS. Samples grading above 200 g/t Ag are reanalyzed by fire assay. Rigorous quality controls (QaQc) are applied at both locations.
