Abcourt Mines Inc. (TSX-V: ABI) (OTCQB : ABMBF) is pleased to announce assay results from all holes drilled in the East Extension of the South Zone on its Flordin property (100% ABI). This gold-bearing zone was discovered in the mid-1980s by Cambior. A total of four (4) 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, we confirm the continuity of the South Zone to our 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 our hole FL-25-282 and returns 1.1 g/t gold over 47.2 metres including 7.6 g/t gold over 3 metres.
• The characteristic high-grade gold mineralization recognized in all of our 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 our holes and seems to thicken as we move east. Mineralized envelopes, several tens of metres thick were intercepted with only 4 holes for a total of less than 2500 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 our 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 our drilling in 2023 (see press release dated January 30, 2024) and in 2025 in the Cartwright area (see press releases dated January 30 and February 11, 2025). We are therefore able to recognize and trace this type of high-grade gold mineralization over a distance of more than 1.8 km.

Quality Control Measures

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 MSALABS laboratory in Val-d’Or, Quebec using the Photon Assay™ method. The samples were crushed to 70% passing two millimeters with a 500-gram division for gamma ray assay for gold. According to MSALABS’ 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 Robert Gagnon, P.Geo., Vice-President Exploration of Abcourt Mines, a Qualified Person as defined by NI 43-101.
