West of Boumadine, Expands Footprint and Reports High-Grade Results from
Boumadine Main Trend and Tizi Zone
MONTREAL, Sept. 15, 2025 -- Aya Gold & Silver Inc. (TSX: AYA; OTCQX: AYASF) (“Aya” or the “Corporation”) is pleased to
announce new drilling results supporting the discovery of new gold zone at Asirem Zone, west of the Boumadine Main Trend in
Morocco, highlighting the zone’s emergence as a promising new target. Aya also reports high-grade drill results from the

“The discovery and new gold zone at Asirem, west of Boumadine’s Main Trend confirms that Boumadine is
evolving into a true district-scale asset with multiple mineralized trends,” said Benoit La Salle, President & CEO.
“Drilling has traced gold over eight kilometers of strike at Asirem, with geophysics pointing to more than ten
kilometers of potential. Along with grab samples grading up to 12.2 g/t gold and 4.1% copper, this new corridor
highlights promising exploration opportunities. With a PEA on the Boumadine Main Trend targeted for release by
year-end, these results highlight additional zones of mineralization, reinforcing Boumadine’s scale and optionality
as one of Morocco’s most significant emerging precious metals discoveries.”

2025 Exploration Results
This year, 346 diamond drill holes (“DDH”), 37 reverse circulation holes (“RC”) and 20 multi-purpose drill holes (“MP”) totaling
102,979m 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, including the recently discovered Asirem Zone.
The majority of results have been received for drill holes up to BOU-DD25-583 (Table 1, Table 2, Figure 3, Figure 4 and
Appendix 1).
Results received so far in 2025, including holes BOU-DD25-584 and BOU-DD25-572, confirm the high-grade continuity of the
Main Trend, which remains open in all directions. Today’s results, also extend Imariren mineralization to 1.2km. The Imariren
and Tizi zones remain open in all directions.
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.

Figure 4 – Surface Plan of Boumadine South Zone with New DDH Results
Figures 5 shows the recently received grab results on the newly discovered Asirem zone, which reveals high-grade parallel
structures with results up to 12.2 g/t Au and 4.1% Cu, and highlight the potential of the area. The Au-Cu surface anomalies
coincide with a strong N080 geophysical feature and a regional. Figure 6 presents the simplified geology of Asirem in the
discovery drill section.
Geology of Asirem is composed of a package of Neoproterozoic rocks, mainly rhyolitic tuffs in contact or in close proximity
with the Cambrian sedimentary shists. The contact consists of a major normal regional fault oriented N090-N080 injected by
various quartz, quartz-carbonate and barite veins and veinlets containing various degree of Au, Cu and traces of Ag, Pb and Zn.
The veins can locally reach 5m thickness and they regularly form stockworks with traces of pyrite and chalcopyrite. In it
oxidized phase, malachite, azurite and chalcosite are present. The Asirem structure can be followed on surface over a trend of
more than 10km within our permits.

Next Steps
Significant upside potential exists to expand the Boumadine Main Trend, which currently extends 5.4km, the Tizi Zone, which
currently extends 2.0km and the Imariren Zone, with a current extension of 1.2km; the three trends remain open in all
directions. In addition, follow up drilling will take place at the newly discovered 8km Asirem trend. Currently, the Corporation
has mobilized drill rigs to complete the 100,000m to 140,000m drilling program. Half of the drilling is focused along the Main
Trend, Imariren 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 (“Afrilab”) 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 samples representing 1/16th, ranging
from 2 to 4 kilogram is sent for preparation and assaying to African Laboratory for Mining and Environment (“Afrilab”) 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 (“AAS”). 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.

Forward-Looking Statements
This press release contains certain statements that constitute forward-looking information within the meaning of applicable
securities laws (“forward-looking statements”), which reflects management’s expectations regarding Aya’s future growth and
business prospects (including the timing and development of new deposits and the success of exploration activities) and other
opportunities. Wherever possible, words such as “promising”, “expected”, “pointing”, “opportunity”, “targeted”, “significant”,
“potential”, “plan”, “additional”, “grow”, “significant”, 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. Specific forward-looking statements in this press release include, but are not limited to,
statements and information with respect to the continuity of the mineralization and its grade, the potential to meaningfully grow
resources and for all deposits grow in any direction, the potential for any drilling result to confirm the existence of a new zone,
the capacity of the Corporation to complete and publish the PEA by year end, the new Asirem zone to extend to 10km as
indicated by the geophysics, the new corridors to translate into new exploration opportunities, the existence of a significant
upside to expand the Boumadine Main Trend, and to execute on planned drilling in the area through the remainder of 2025.
Although the forward-looking information contained in this press release reflect management’s current beliefs based upon
information currently available to management and based upon what management believes to be reasonable assumptions, Aya
cannot be certain that actual results will be consistent with such forward-looking information. Such forward-looking statements

incorrect. These assumptions include, among other things, the ability to obtain any requisite governmental approvals, obtaining
regulatory permits for on-site work, importing goods and machinery and employment permits, the accuracy of Mineral Reserve
and Mineral Resource Estimates (including, but not limited to, ore tonnage and ore grade estimates), the price of silver, the
price of gold, exchange rates, fuel and energy costs, future economic conditions, anticipated future estimates of free cash
flow, and courses of action. Aya cautions you not to place undue reliance upon any such forward-looking statements.
The risks and uncertainties that may affect forward-looking statements include, among others: the inherent risks involved in
