    • On April 16, 2024, the Corporation announced an updated NI 43-101-compliant Mineral Resource Estimate for its Boumadine project that incorporates drilling from 2018 to 2023.
      • Indicated Mineral Resources of 2.0Mt at 113 g/t Ag, 2.51 g/t Au, 4.32% Zn and 1.07% Pb containing an estimated 7.4 Moz of Ag, 165 koz of Au, 88 kt of Zn and 22 kt of Pb.
      • Inferred Mineral Resources of 23.6 Mt at 85g/t Ag, 2.62 g/t Au, 2.32% Zn and 0.84% Pb containing an estimated 64.7 Moz of Ag, 1.98 Moz of Au, 546 kt of Zn and 198 kt of Pb.
        

"We started 2024 with a strong performance that provides us with runway to execute on our growth strategy objectives and guidance this year," said Benoit La Salle, President & CEO. "We made significant progress at Zgounder in the quarter. The expansion is 89% complete, on budget and on schedule to start commissioning in Q2. At our operations, we built inventory from mining lower grade ore from the open pit to access higher grade zones in addition to mining lower grade, underground stope extensions that were identified outside of our modeled resource. Zgounder also returned high-grade drill results at the granite contact, which continues to be a source for mineralization.

"In parallel, we announced a significantly increased resource update at Boumadine, and have since extended its strike to 5 kilometers and secured 7 additional permits. With $111 million in cash and restricted cash at quarter-end, we remain fully funded to complete the mine expansion and our aggressive exploration programs. We expect 2024 to be an exciting year for the exploration team as we focus on delivering the expansion and our guidance."

Q1-2024 Operational and Financial Highlights (in 000's of $)

Q1-2024 Operations Review

In Q1-2024, 22,229 tonnes of ore were mined from the open pit. As expected, the first benches of the open pit were lower grade and oxidized, and their mining exposed higher-grade zones. As per the mine sequence, higher-grade zones are being mined along with current zones which will result in higher average grade from the open pit throughout the remainder of the year. During the quarter, ore was mined from the open pit at an average strip ratio of 18, which is expected to decrease to 13 for the year. The open pit is mined using a mining contractor. To date, the contractor's performance and the costs associated to mining the open pit are to plan.

The underground mining team worked on ore drives, defining future underground stopes, and improving old stopes to make them safe for operations in the quarter. They followed the Corporation's standard mining methods to achieve a high ore recovery. Several historical high-grade stopes are being completed with lower-grade extensions before the stopes are backfilled with cemented rock fill. The combination of these activities resulted in mining of lower grade ore during Q4-2023 and Q1-2024. Total mining rate for the quarter averaged 1,175 tpd, for a total of 106,880t of ore mined in the quarter. Overall, stockpiles were at 275,663t as at March 31, 2024. As planned, the mine capital development rate has been reduced to focus on ore drives. A total of 579m of lateral development was completed for the quarter.

In Q2, six stopes are in operation with more to be added throughout the year. Additional stopes are being defined, and historical stope rehabilitation continues. The team expects to reach higher grade stopes in the coming quarters as known, defined, vertical orebodies become accessible via the 1,925 level.

In Q1-2024, 81,331t of ore were processed. Total mill availability for the quarter was 96.3%. Mill feed grade was 173 g/t Ag, and recovery averaged 81.8%. The lower recovery rate was due to processing oxidized ore from the first benches of the open pit. Recoveries will return to historical levels once the surface oxidized ore is consumed and fresh ore is mined as the open pit progresses. In the new plant, recoveries for both the oxidized and fresh ore are expected to be equal. Total production of 366,362 oz was achieved in the quarter.

The Q1-2024 mining rate, grade, and mill recovery rate were factored into the 2024 guidance.

Zgounder Expansion

At the end of Q1-2024, construction of the plant and surface infrastructure continued to track on budget. Overall, the expansion project was 89% complete, compared to 80% at the end of the fourth quarter.

• Mine expansion is fully funded and on track to start commissioning in Q2-2024.
• Tailings and water storage facilities are complete.
• Processing plant is approximately 87% complete.
• Electrical infrastructure is 90% complete.
• Underground development of 9,031m completed, 94% of the initial lateral development program.
• Approximately 83% of vertical development completed.
• Production from the open pit is ongoing with 103,449t stockpiled.
• On target to complete expansion within the capital cost estimate.

2024 Exploration Programs

• Zgounder
  

In Q1-2024, the Corporation maintained its focus on defining at-depth mineralization, with 7 underground rigs and 1 surface rig drilling a total of 8,710m of DDH on the Zgounder mining permit. A total of 15,000m for exploration was assigned to the Zgounder Mine permit in 2024 to follow up on underground targets generated by the 2023 program.

Preliminary results in the quarter continue to confirm high-grade silver mineralization near the granite contact. In particular, holes ZG-SF-23-084 and ZG-SF-23-092 are hosted within the rhyolite, which was previously believed to be barren, opening a new area for exploration.

• Zgounder Regional
  

A 10,000m drill program has been established for Zgounder Regional in 2024 with the aim of finding mineralization similar to the near-mine permit. Two surface rigs were mobilized during the quarter, carrying out a total of 2,998m on Zgounder East and Zgounder South targets adjacent to the mine. Results are still pending.

• Boumadine
  

Through 2024, the Corporation plans to mobilize seven drill rigs to complete a 120,000m drill program on Boumadine. Half of the program will test the continuation of the known trend and carry out infill drilling. The remaining 50% will focus on geological targets generated by 2023 work and will be informed by the ongoing hyperspectral and high-resolution geophysical surveys.

The first quarter saw the Corporation drill 15,027m DDH at Boumadine to explore along strike and test new targets. Results confirmed high-grade mineralized zones in the central and northern portions of the Main Trend with BOU-DD23-180 intersecting 1,039 g/t AgEq over 23.5m (6.41 g/t Au, 116 g/t Ag, 4.7% Zn, 0.6% Pb and 0.4% Cu).

At the end of the first quarter, the Corporation had acquired six new exploration permits in the vicinity of the Boumadine Main Trend. These additions boost the Boumadine total land package to 141.4 square km, a 346% increase compared to year-end 2023.

A 6,515 linear km airborne MobileMT geophysical survey was flown over the Boumadine land package, including the new permits, in the first quarter with a view of obtaining at-depth drill targets.
