ABCOURT INTERSECTS 1.1 G/T GOLD OVER 47.2 METRES AND CONFIRMS THE EAST EXTENSION OF THE SOUTH ZONE ON THE FLORDIN PROPERTY IN THE LEBEL-SUR-QUEVILLON AREA

Abcourt Mines Inc. has released assay results from all holes drilled in the eastern extension of the south zone on its Flordin property (100 per cent owned by Abcourt Mines). This gold-bearing zone was discovered in the mid-1980s by Cambior. A total of four holes for a total of 2,340 metres were drilled directly in the eastern extension of the south zone. Hole FL-25-282 intersected a large, mineralized envelope of 47.2 metres at 1.1 g/t gold. With this first phase of work, the company confirms the continuity of the south zone to its 2023 drilling and to the Cartwright zone.

Pascal Hamelin, president and chief executive officer, comments: "The drilling campaign in the south zone area was a great success, with all of our holes (four in total) intersecting the gold-bearing structure and returning gold grades. A significant gold envelope several tens of metres thick was uncovered during this campaign. We have demonstrated that the type of high-grade gold mineralization that is associated with pyrite-silica-hematite and sericite bands is present throughout our Flordin property. Gold mineralization appears to be continuous over more than 1.8 kilometres between the south zone and the Cartwright zone. The goal of phase 2 drilling will be to connect the zones between them. Our exploration team is already in the process of interpreting and planning it."

Highlights:

• A significant mineralized zone was intersected in hole FL-25-282 and returned 1.1 grams per tonne (g/t) gold over 47.2 metres, including 7.6 g/t gold over three metres.
• The characteristic high-grade gold mineralization recognized in all of the company's drill holes is traceable over more than 1.8 kilometres.
• Significant mineralized envelopes, several tens of metres thick, were confirmed during this campaign.
• The south zone is continuous and remains unexplored laterally and at depth.

The 2025 holes drilled in the eastern extension of the south zone are the deepest ever drilled in this area of the property. The south zone has been recognized in all of the company's holes and seems to thicken as Abcourt Mines moves east. Mineralized envelopes, several tens of metres thick, were intercepted with only four holes for a total of less than 2,500 metres. To generate such a gold intersection, a major mineralizing system is required and the goal of phase 2 drilling will be to confirm this hypothesis. Historical descriptions are consistent with the mineralization observed in the company's drill core. Indeed, the type of mineralization that characterizes the south zone, namely bands of pyrite associated with bands of pink hematized silica with sericite and bands of magnetite without quartz vein. This type of mineralization has already been recognized in the company's drilling in 2023 (see news release dated Jan. 30, 2024) and in 2025 in the Cartwright area (see news releases dated Jan. 30, 2025, and Feb. 11, 2025). The company is therefore able to recognize and trace this type of high-grade gold mineralization over a distance of more than 1.8 kilometres.

Quality control measures (QA/QC (quality control/quality assurance))

Following an analytical quality assurance and quality control program, blank samples and certified reference materials were added to the NQ half core samples, and were shipped and analyzed by the MSA Labs in Val d'Or, Que., using the Photon Assay method. The samples were crushed to 70 per cent passing two millimeters with a 500-gram division for gamma ray assay for gold. According to MSA Labs' internal procedure, blank and standard samples are inserted. MSA operates numerous laboratories around the world and maintains ISO-17025 accreditation for many metal determination methods. MSA is an ISO-17025-accredited laboratory for the photonic analysis method. The drilling, core description and assay preparation work was carried out under the supervision of Mr. Gagnon, a qualified person as defined by National Instrument 43-101.
