Aya Gold & Silver acquires copper-silver portfolio

Adding 139 km² Land Package Near Zgounder

MONTREAL, Sept. 01, 2026 (GLOBE NEWSWIRE) -- Aya Gold & Silver Inc. (TSX: AYA; NASDAQ: AYA) (“Aya” or the “Company”) is pleased to announce that it has entered into an agreement to acquire a 139 square kilometers ("km²") portfolio of exploration permits in Morocco (the “Cu-Ag Portfolio”), including a 19 km² mining license, approximately 35 km West of Aya’s Zgounder Silver Mine ("Zgounder").

The acquisition is expected to further consolidate Aya’s land position in the Zgounder district and provide exposure to a large, underexplored copper-silver ("Cu-Ag") system with multiple styles of mineralization and significant exploration potential.

Project Highlights

The Cu-Ag Portfolio Acquisition Adds 139 km² Land Package Near Zgounder (Tizi area)

Strong historical trenching: returned 15 meters ("m") grading 0.65% Cu and 33 grams per tonne ("g/t") Ag. 1

High-grade silver surface samples: up to 837 g/t Ag from historical grab, consistent with Aya's sample returning 500 g/t Ag.

High-grade copper surface samples: up to 4.6% Cu from historical grab, consistent with Aya's sample returning 4.0% Cu.

Principal Cu-Ag horizon over 2 km: confirmed by Aya field visit.

Multiple mineralization styles identified: sediment-hosted/stratiform copper, structurally controlled vein- and shear-hosted Cu-Ag mineralization, and associated alteration zones.

Broader district-scale potential: historical workings and copper occurrences indicative of a potentially larger mineralized system.

Existing exploration access: approximately 20 km of road access associated with historical manganese workings.

Significant untested upside: historical work has been limited to the manganese horizon with the exception of recent reconnaissance and surface exploration for Cu.

1 Historical results referenced above were reported by the previous operator and a qualified person has not done sufficient work to classify the historical estimates as current; Aya is not considering the historical estimates as current and cautions that further work is required to confirm them. Surface grab samples are selective by nature and are not representative of true width, overall grade of mineralization, or is indicative of any further mineralization.

“This acquisition is consistent with our vision of building a dominant land position around Zgounder and strategically consolidating prospective opportunities in Morocco,” said Benoit La Salle, President & CEO. “Adding 139 km² of compelling copper-silver showings only 35 km from Zgounder is in line with this strategy. We see significant potential to apply Aya’s exploration expertise and establish a new copper-silver platform within our growing Moroccan portfolio.” said Benoit La Salle, President & CEO.

Strategic Rationale

The acquisition represents a low-cost opportunity for Aya to consolidate a land position, adjacent to its existing Moroccan operating footprint. Located approximately 35 km West of Zgounder (Figure 1 and 2) the property lies in a similar geological setting to our operating mine, with Neoproterozoic volcano-sediment in proximity to the Askouen granite.

The combination of at-surface, high-grade, Cu-Ag mineralization (Figure 3 and 4), multiple mineralization styles shown by both historical results and sampling completed during our site visits, existing site access, and significant untested strike potential presents Aya with an attractive exploration platform.

The Cu-Ag Portfolio complements Aya’s existing properties and reinforces its strategy of leveraging its operating presence, technical expertise and infrastructure in Morocco to advance new opportunities.

Transaction

Aya, through its wholly owned subsidiary, will acquire all issued and outstanding shares of the seller.

Total consideration for the acquisition is C$4.0 million, payable in Aya common share.

The transaction remains subject to customary closing conditions, including satisfactory confirmatory due diligence, applicable Moroccan and Canadian regulatory approvals, and the Toronto Stock Exchange ("TSX") approval. The Aya common shares issued in connection with the transaction will be subject to applicable statutory sale restrictions.

Closing is expected to occur following satisfaction of the applicable conditions precedent.

Next Steps

Over the next 12 to 18 months, Aya plans to initiate exploration of the Cu-Ag Portfolio to assess the potential for discoveries. We plan to carry-out stream sediments geochemistry, high resolution hyperspectral study, airborne geophysics as well as mapping and prospecting. Results from this phase will inform the next stage of exploration.
