ABCOURT MINES REPORTS RECORD DEVELOPMENT FOR Q4 2026 AT ITS SLEEPING GIANT MINE, FOLLOWED BY A 160% INCREASE IN TONNAGE PROCESSED

Abcourt Mines Inc. has presented a major, unaudited operational update for the fourth quarter ended June 30, 2026, as well as the year-to-date consolidated results for its Sleeping Giant gold mine, located in Abitibi, Quebec.

Q4 2026 operational highlights (quarter ended June 30, 2026):

• Strong acceleration in mill processing: A total of 11,891 tonnes of ore were processed during Q4, representing an impressive 160-per-cent increase compared with the previous quarter (7,445 tonnes in Q3). The month of June marked a historical peak for the year with 5,229 tonnes milled.
• Continuing gold production: Gold production in Q4 amounted to 720 ounces produced (with 646 ounces poured), bringing the annual cumulative total to 3,628 ounces produced (including 2,647 ounces poured for the fiscal year).
• Underground development up 180 per cent: Underground mine development reached a record 554 metres in Q4 (including 215 metres in the month of June alone), compared with 307 metres in Q3.
• Intensification of exploration drilling: Diamond drilling totalled 11,059 metres in Q4, representing a 155-per-cent increase compared with Q3, demonstrating the sustained effort to expand the mine's resources.
• Start of the first long-hole stope: The drill is currently operating in the mine, allowing the start of long-hole stope extraction.

Detailed operational data -- 2025-2026 fiscal year

The following table presents the monthly and quarterly evolution of mill activities and underground operations at the Sleeping Giant mine.

Production variance analysis:

• Milled tonnage (Q4 versus Q3): plus 160 per cent in mill throughput capacity, driven by the continuing training of the underground work force;
• Average grade: the average grade for the fiscal year stands at 4.18 grams per tonne gold; the decrease in Q4 (2.1 grams per tonne) reflects the processing of lower-grade development zones, typical of a transitional expansion phase in underground workings;
• Ounces produced (Q4 versus Q3): 60 per cent of Q3 production, directly correlated with the lower grade during these three months, though partially offset by the increased mill throughput.

Underground mine development experienced a major leap in Q4 with 554 metres completed (a 180-per-cent increase compared with Q3). Gallery rehabilitation also showed a marked increase of 231 per cent (1,052 metres compared with 455 metres in Q3), which will help improve the number of available working faces in the future.

A message from management

"This fourth quarter demonstrates the success of our ramp-up phase at Sleeping Giant," stated Pascal Hamelin, president and chief executive officer of Abcourt Mines. "Despite temporarily lower grades this quarter, due to mine plan sequencing, mill efficiency and daily throughput have reached new heights. With over 11,000 metres of drilling and 1,052 metres of rehabilitated galleries during the last quarter, we are laying solid foundations for the upcoming fiscal year."
