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

MONTREAL, Sept. 16, 2026 (GLOBE NEWSWIRE) — Aya Gold & Silver Inc. (TSX: AYA; NASDAQ: AYA) (“Aya” or the “Company”) 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-24-155 intercepted 783 grams per tonne (“g/t”) silver (“Ag”) over 13.0 metres (“m”)
  • Hole ZG-RC-24-354 intercepted 501 g/t Ag over 11.0m, including 4,000 g/t over 1.0m
  • Hole ZG-SF-25-702 intercepted 1,553 g/t Ag over 1.4m
• Intersections in the Central Area:
  • Hole DZG-SF-26-945 intercepted 3,501 g/t Ag over 3.5m, including 7,717 g/t Ag over 1.5m
  • Hole T28-26-1334 intercepted 4,770 g/t Ag over 2.4m
  • Hole T28-26-1333 intercepted 1,362 g/t Ag over 8.4m, including 2,873 g/t Ag over 3.6m
  • Hole T28-26-1404 intercepted 762 g/t Ag over 12.0m
• 16,217m or 54.1% of the 2026 exploration program has been drilled year to date.

“Today’s high-grade results, highlighted by DZG-SF-26-945, continue to reinforce the strength and continuity of silver mineralization both around the open pit and across the central zone,” said Benoit La Salle, President & CEO. “At the same time, development of the exploration drift at the 1,825-metre level is progressing well, setting the stage for drilling west of the fault to begin in Q4 and providing an important new opportunity to expand the mineralized footprint.”

This release contains results from 97 holes, which include one surface diamond drill holes (“DDH”), 31 underground DDH, seven reverse circulation drill hole (“RC”), 45 T28 and 13 YAK holes (T28 and YAK: percussion drilling using an air-compressed hammer). For a full summary of today’s results, refer to Appendix 1 and 2.

Quality Assurance

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.

Forward-looking statements are included to provide information about management’s current expectations, estimates and projections regarding Aya’s future growth and business prospects (including the timing and development of deposits and the success of exploration activities) and other opportunities as of the date of this press release.

All statements, other than statements of historical fact included in this press release, regarding the Company’s strategy, future operations, technical assessments, prospects, plans and objectives of management are forward-looking statements that involve risks and uncertainties. Wherever possible, words such as “aim”, “anticipate”, “assume”, “believe”, “estimate”, “expect”, “goal”, “guidance”, “intend”, “objective”, “plan”, “potential”, “strategy”, “target”, and similar expressions or statements that certain actions, events or results “may”, “could”, “would”, “might”, “will”, or are “likely” to be taken, occur or be achieved, have been used to identify such forward-looking information. Forward-looking statements in this press release include, but are not limited to, statements with respect to: the 2026 exploration program; the timing and commencement of drilling west of the fault at Zgounder; and the potential expansion of the mineralized footprint at Zgounder.

Forward-looking information is based upon certain assumptions and other important factors that, if untrue, could cause the actual results, performance or achievements of the Company to be materially different from future results, performance or achievements expressed or implied by such information or statements. There can be no assurance that such information or statements will prove to be accurate. Key assumptions upon which the Company’s forward-looking information is based include without limitation, assumptions regarding development and exploration activities; the Company’s ability to execute its business plans and objectives; the ability to commence and successfully execute planned drilling and exploration activities; the accuracy of the Company’s geological interpretations and the continuity of mineralization in areas targeted for exploration; the continued validity and good standing of the mining titles necessary to conduct the planned exploration activities; the timely receipt of necessary approvals or permits; the ability to obtain timely financing on reasonable terms when required; future social, economic and political conditions remaining consistent with those currently prevailing; the availability of qualified contractors, consultants, suppliers, equipment, materials and labour on commercially reasonable terms; and the cooperation of government authorities, municipalities and other stakeholders.
