Abcourt Mines Inc. (TSX-V: ABI) (OTCQB: ABMBF) is pleased to announce that it has completed all drilling east of the Cartwright stripping to the boundary of its Flordin property and the Kinebik property now owned by Vior Gold Corporation (see Figure 2). Eleven (11) holes were drilled on two NW-SE lines for a total of 2,960 metres. As of today, 3,900 metres of drilling have been completed during the 2026 drilling campaign, which totals 20,000 metres. The next area to be drilled is located 300 metres west of the Cartwright stripping. Four (4) holes will test the lateral and depth extensions of stripping no 25-02 (9.5 g/t gold over 7 metres including 112.7 g/t gold over 0.5 metres) and no 25-01 (1.4 g/t gold over 4.0 metres). See press release dated September 25, 2025.

Summary of Drilling Completed in the East part of the Property

New drilling in the eastern sector of the property extended the known mineralized zones to the boundary of our Flordin property with the Kinebik property. All the drill hole intersected gold values. Hole FL-26-291 returned 1.7 g/t gold over 12 metres, including 15.2 g/t gold over 1 metre, within 50 metres of our property boundary. Based on geological observations and assay results, we can confirm that despite the continuity of the structure, mineralization, alteration and gold grades are less significant east of the Cartwright stripping than to the west. See Table 1 for a summary of the eastern sector drill results. With the eastern holes completed, the 2026 campaign will move westward and attempt to link the mineralized zones of stripping 25-01 and 25-02 with the holes drilled in 2023, to finally end in the South Zone area. With the 2026 drilling rate reached and steady, we expect to drill no less than 2,000 metres per month, with only one drill rig in operation.

Pascal Hamelin, President and Chief Executive Officer, commented: “The eleven holes drilled in the eastern sector of the property confirmed the continuity of the mineralized zones observed east of the Cartwright Trench to the boundary of our Flordin property with the Kinebik property. Given the interest generated by the auction of this property, it became imperative for Abcourt Mines to validate and corroborate the geological information in this area, and it has been done. We can now focus our efforts west of the Cartwright Trench by continuing to define our high-grade gold corridor over 2 kilometres in length to the South Zone.”

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 of Exploration of Abcourt Mines, a Qualified Person as defined by NI 43-101.
