Zgounder Expansion Feasibility Study

At quarter-end, the Zgounder FS was 73% complete and the following milestones had been achieved:

• Process: 90% completed

• Hydrology: 95% completed

• Environment: 95% completed

• 40,703m of the scheduled 42,000m diamond drill program have been completed

• The exploration database is expected to close in mid-November to complete the resource update.

“The third quarter marks a year that the Aya team has been working together, and we saw the benefit of

this in our results,” said Benoit La Salle, President & CEO. “ In the most challenging production quarter,

we continued the trend of strong operational performance, posted record cash flow , closed a C$70

million financing, announced ongoing exploration success at Zgounder and initial promising results

from Imiter bis, all while maintaining a heavy focus on mine development and advancing two feasibility

studies. This lays the groundwork for several catalyst-rich quarters, starting with the updated resource

estimate for Zgounder.”

Q3-2021 Exploration Highlights

Zgounder Exploration

The quarter saw the Corporation return high-grade assays that defined the new Zgounder East Zone and

expanded the down-dip and on-strike continuity of Zgounder mineralization. These areas remain open

for future growth. Within the Zgounder East Zone, results confirmed continuity along strike with notable

high-grade intervals such as holes ZG -21-40 and ZG -21-41 opening the zone at depth in previously

undrilled areas below 2,000m. Significant results such as ZG-SF-21-25 extended Zgounder mineralized

systems to the granite contact within the explor ation target and will be followed up in Q4-2021.

Additionally, hole ZG -SF-21-39 define d continuous high -grade mineralization below current mine

galleries and remains open in both directions.

As a result of the positive results received year to date, the 2021 drill program at Zgounder was

expanded from 35,000m to 42,000m into year -end. In the quarter, 15,834m of diamond drilling were

carried out for a total of 40,703m completed to date (excludi ng T28 drilling). Currently, five drills are

operating at Zgounder, three on surface and two at depth. The updated mineral resource estimate

remains on track for delivery before year -end and will form the basis of the Zgounder maiden reserve

estimate that will support the feasibility study.

The Corporation has engaged Geotech to fly a VTEM™ heliborne terrain, magnetic and radiometric

geophysical survey over the entire Zgounder Regional project before year-end.

Imiter bis Exploration

In the quarter, the Corporation’s initial fieldwork program at its Imiter bis Project identified a north-south

structure extending over four kilometers long. Highlight grades from 2021 surface grab and channel

sampling programs include 15.42 g/t Au, 289 g/t Ag, 5.51% Cu, 31.23 % Pb and 10.23% Zn, showing

potential for epithermal Au-Ag occurrence and copper-rich deposit. Five priority drill target zones were

identified, and a 4,000m diamond drill program began in October 2021 on three of the zones.

During the quarter, a detailed ground magnetic survey was conducted over the same three zones

together with a high-resolution multi -spectral study , T he Corporation will also fly Geotech’s VTEM™

heliborne terrain, magnetic and radiometric geophysical survey over the property before year-end.

Q3-2021 Zgounder Optimisation and Capital Projects

In the quarter, the Corporation ramped up its capital project activities including refurbishment of the

cyanidation plant, replacement of the flotation plant cone crusher, ongoing construction of a new

underground explosive depot, and the start of a new mine access at the 2,075m level.

Mining operations benefited from a full quarter using the new cut -and-fill stoping mining method and

from easier extraction because of the wider access bay. As a result of the heavy development work in

the quarter, mine extraction reached 609 tpd with 50,836t of ore blasted. Preparation for the 2022 mine

plan is advancing well , with additional mining equipment being purchased to continue the

mechanization of mining operations.

Silver recovery in the quarter increased to 81% relative to 63% for the same period in 202 0. The slight

decrease in Q3 -2021 recovery compared to Q2-2021 is pr imarily due to a recovery rate of 79% at the

cyanidation plant. Both issues are being addressed by the construction of a 60,000m3 water retention

basin and a tailings thickener to minimize water discharge to the tailings dam. Recovery at the

cyanidation plant is expected to improve in Q4-2021.

In the quarter, availabilities reached 87% and 89% for the flotation and cyanidation plants, respectively.

Availability, which was impacted by a two -day planned shutdown of the flotation plant and a two -day

unplanned shutdown of the cyanidation plant , is expected to continue to improve as maintenance

processes mature.
