The gold inventory in the circuit at the end of the month of February was 1,020 ounces.
Work at the camp continued in February with the addition of a 36-room block, on top of the existing 50 rooms. This
second phase of adding rooms is expected to be completed in the coming weeks. Construction of the third block of
rooms is scheduled to begin in early summer.
Factors impacting the production
A mechanical failure in the hoisting skip temporarily slowed operations at Abcourt Mines, but the situation has now
been fully resolved. To strengthen the resilience of its facilities, the Corporation has already ordered a spare skip
and received some critical parts. This strategic inventory will ensure an immediate response and maintain
production continuity should a similar situation arise in the future.
During the first quarter of 2026, Abcourt Mines intensified its recruitment efforts, hiring 25 new employees in
January, followed by 8 more in February. While this workforce is essential for growth, the training period in February
temporarily impacted production levels, as new recruits are naturally less efficient than experienced staff. To ensure
optimal skills transfer, five dedicated trainers have been providing ongoing support since the beginning of the year.
Management anticipates that once these miners are fully operational, extraction capacity will increase, allowing for
a steady rise in ore production.
Abcourt-Barvue
Abcourt is pleased to announce that it is currently conducting a geological reassessment of historical data for its
Abcourt-Barvue project, a strategic asset of significant size and value recognized for its substantial silver and zinc
resources. The deposit has historically produced over 5.5 million tonnes. According to the historical mineral
resource estimate updated in 2019, the project has measured and indicated resources totaling 8.08 million tonnes
with average grades of 55.45 g/t silver and 3.06% zi nc. Our geologists are currently focused on the rigorous
interpretation of data prior to 2019 to define the next phases of exploration, with the ultimate goal of reopening
this mine. With a historical silver recovery rate of 77% and recent metallurgical testing suggesting potential
optimizations, Abcourt believes that maximizing the value of this asset is critical in the current metals market
environment.
Corporation Communication
Abcourt has significantly increased its strategic visibility since the beginning of 2026, notably through a prominent
presence at international events such as PDAC and Pre- PDAC in Toronto. These platforms have allowed
management to strengthen its ties with the financial community and highlight the potential of its assets. In addition
to these trade shows, the Corporation has increased its targeted media appearances, granting in-depth interviews
to specialized broadcasters such as Crux Investor and RCTV. These direct marketing efforts aim to ensure greater
transparency and position Abcourt as a key player for institutional and retail investors.
Corporate Update
Abcourt announces that Mr. Loïc Bureau is leaving his position as Chief Operating Officer of Abcourt Mines,
effective immediately, to pursue other opportunities. The operations teams will now report on an interim basis to
Pascal Hamelin until a new Chief O perating Officer is appointed. Abcourt remains fully committed to achieving its
growth objectives toward commercial production at the Sleeping Giant mine.
