Abcourt Intersects 24.3 g/t Over 1.9 m Including 41.9 g/t Over 0.6 m in the 785N Zone and Provides an Update on Its Sleeping Giant Activities

Abcourt Mines Inc. ("Abcourt" or the "Corporation") (TSX Venture: ABI) (OTCQB: ABMBF) is pleased to report new drilling results and an update on its activities at the Sleeping Giant mine.

In 2025, Abcourt completed 36 underground drill holes totaling 5,632 meters. Of these holes, seven target the 785N zone and the underlying areas for a total of 3,316 meters. This 785N zone is in a new sector to the east and at depth of the developed sectors of the mine. After releasing the results of two of these holes earlier this year, Abcourt is today releasing the results of two more holes, 78-888 and 78-890.

The highlights included in this press release are as follows:

• Hole 78-890 intersected the 785N Zone at the targeted depth ( 24.3 g/t over 1.9 metres including 41.9 g/t over 0.6 metres );
• Abcourt will add a third underground drill rig to accelerate its resource conversion drilling program at the upper levels of the mine;
• Abcourt continues work in anticipation of the closing of previously announced financing which will enable the mine to develop towards production.
  

Pascal Hamelin, President and CEO, comments: "Since underground drilling began in the fall of 2023, our goal has been to increase the quality and quantity of the mineral resources at Sleeping Giant. This drilling, along with the work accomplished by our Sleeping Giant team, has allowed us to build a solid financial plan for mine development and rapid production ramp-up. Indeed, our surface and underground infrastructure are in very good condition, which will allow us to quickly develop the mine towards a profitable production. Furthermore, we are very excited to see this new promising sector 785N near our underground infrastructure. We believe that we will be able to extend the life of the mine once it is in production."

The main results of holes 78-888 and 78-890 are displayed in Table 1:

The main drilling results are illustrated in Figure 1

Figure 1: Main Results – Interception of 785N Zone.

Drilling data reveal:

• A concordance between the intervals intersected by drill holes 78-888 and 78-890 and those encountered in nearby previously drilled holes 66-1126-11, 78-885, and 78-886
• The presence of several mineralized intervals upstream of the 785N Zone. These subparallel mineralized veins are part of the vein system underlying the 785N Zone, as previously mentioned in the February 13, 2025 press release.

Drilling work continues in the 785N zone. Results are being interpreted as they are received. Abcourt will publish all results following the first phase of work.

Alongside the program to enhance the deep mining potential of the Sleeping Giant Mine, drilling activities are currently underway in the upper part of the mine. These efforts aim to:

• Maximize the conversion of inferred resources into indicated resources;
• Update the mineral resource estimate for Sleeping Giant property;
• Support the engineering studies necessary to optimize the mining plan and initiate production.
  

Renewal of the Drilling Contract with G4 Drilling

Abcourt has renewed the underground drilling contract with G4 Drilling and has requested the addition of a third underground drill rig. This rig will be designed for conventional mining requirements to facilitate movement and installation. This additional drill rig should be ready to drill in a few weeks to accelerate the conversion of our inferred resources to indicated resources and better define our production stopes if needed.

Progress of Financing Procedures

The standard due diligence review, the site visit by an independent team appointed by the potential lender, and the preparation of the final documents for the 8M USD loan are progressing according to the established schedule, marking a significant step forward in the development of mine. See the press release issued April 10 ^th for the details on the terms of the proposed loan. This review also provided an opportunity to highlight the strategic potential of Sleeping Giant's infrastructure, while confirming our team's exemplary preparation for the restart of operations.

Quality Control Measures (QA/QC)

The drilling and core description work was carried out under the supervision of Mohamed Haithem Bennia, geo, Superintendent Geology, qualified person according to Regulation 43-101.

The core is also oriented using high-precision digital tools (Reflex ACTIII) to provide a better understanding of the geological structure.

The quality assurance and control protocols for the analyses include the insertion of blank, standard and duplicate samples every 25 samples, in addition to the internal control of the laboratory samples.

The half-cores were prepared at the Sleeping Giant mine's internal laboratory according to industry standards.

The samples used in the preparation of this press release were analyzed by the MSALABS laboratory in Val-d'Or, Quebec, using the Photon AssayTM method. MSA operates numerous laboratories worldwide and maintains ISO-17025 accreditation for many metal determination methods. MSA is an ISO-17025 accredited laboratory for the Photon AssayTM method.
