Underground Development Acceleration and Strategic Operational Transition

Rouyn-Noranda, Canada, August 25, 2026 – Abcourt Mines Inc. (“Abcourt” or the “Company”)

(TSX Venture: ABI) (OTCQB: ABMBF) is pleased to announce its operational results for the

month of July 2026, as well as the progress of the Long- Hole stopes to date. This update

highlights the steady advancement of the mine development plan and the transition toward

optimized mining methods, targeting higher-grade production and larger tonnage.

Operational Review: July 2026

The month of July was marked by a key technical transition phase. The noticeable increase in

gold pours observed this month primarily reflects the cleanup of inventory accumulated in the

processing circuits. Furthermore, the priority given to underground development temporarily

impacted extracted grades, a situation expected to normalize as work reaches higher -grade

production areas.

Moving Toward Higher Production

The transition to the long-hole (LH) mining method is yielding conclusive results. The first stopes

of this type began in July and are expected to be completed by mid- September. Preliminary

August data confirms their efficiency, notably with the blasting of the first 1,055 tonnes in July at

an unreconciled grade of 6.45 g/t in the 295 -DAC5 sector. These tonnes were milled at the

beginning of August. Additional stopes will be developed in this zone, and the Company expects

to maintain production there through December 2026.

“We are structuring our operations to maximize profitability on every ounce,” stated Abcourt ’s

management. “With the imminent entry into production of Zone 20 and the ongoing development

of Zone 3, the mine is on a robust growth trajectory. Thanks to our sampling rigor and the

continuous refinement of our LH mining procedures ; we are exceptionally well positioned to

increase yield starting at the end of the third quarter.”

The Company reiterates its commitment to transparency and sustainable value creation for all

stakeholders, with the ongoing goal of maximizing project profitability.
