Abcourt Provides Sleeping Giant Project development Update

Rouyn-Noranda, Canada, August 7, 2025 – Abcourt Mines Inc. (“Abcourt” or the “Corporation”) (TSX Venture:

ABI) (OTCQB: ABMBF) is pleased to provide an update on the ramp- up activities at the Sleeping Giant Project in

Eeyou Istchee, Québec.

Pascal Hamelin, President and CEO of Abcourt, commented: “We had a very good start of the project as soon as

we completed the financing with Nebari in early July. We immediately started the installation of the sleep camp on

site. The underground teams began the rehabilitation of the underground openings as well as preparing the mining

of the first stope that began at the end of July. The mill and surfac e teams prepared the mill during the month of

July to start processing material from underground in August. Finally, we also began the hiring process to increase

the size of the development and mining crews. Overall, we’re all excited to start the development and ramp- up of

the project.”

July Activities

• Built a surface stockpile between the mine and the mill of approximately 1,000 tonnes of ore.

• Began to blast the first stope underground in July.

• Started the construction of a 50 persons dormitory. In the coming days, we will complete the installation of

the utilities feeding the dormitory. It’s planned to accept the first persons later in August. The delivery of

the kitchen and rec room are scheduled in a few weeks. The 50-person dormitory is the first phase of a

larger dormitory. Abcourt is in the permitting process for phase 2 to increase the capacity from 50 to 1 00

rooms. The current 50-person dormitory should be enough to accommodate up to 100 workers base on a

7 days in 7 days out, 24 hours a day schedule. Also, we will continue to lodge some workers in the city of

Amos until we complete phase 2.

• Began the works on the tailing facilities. The tailing construction management will consist of a small team

who will execute the construction every year from generally May until October. The new environmental

Certificate of Authorization, received in the Spring 2025, for the pulp storage is good until 2032 at th e

proposed mining rate of 100,000 to 125,000 tonnes per year of ore.

August Outlooks

• Increase the underground activities to start feeding the mill,

• Commission the crushing plant,

• Commission the grinding and leaching circuits to fill the mill circuit.
