Abcourt intersects 9.5 g/t Gold over 7.0 metres in channel, including 112.7 g/t over 0.5 metre, more than 650 metres west of the Cartwright Area of the Flordin Project

ROUYN-NORANDA, Quebec, Sept. 25, 2025 (GLOBE NEWSWIRE) -- Abcourt Mines Inc. ("Abcourt" or the "Company") (TSX Venture: ABI) (OTCQB: ABMBF) is pleased to announce its most recent results from the Flordin Cartwright project where two new strippings were completed. These have extended the current mineralized zone to more than 650 metres while identifying new mineralized zones parallel to previously identified zones that had never been exposed or drilled at depth.

The Campaign

Stripping 25-01 presents mineralization parallel to the historic Adam, Horse and Little Joe zones, further north, while being located close to the main access road. This new mineralized zone, which had never been drilled or sampled, identified a gold grade of 1.4 g/t Au over 4.0 metres in Channel No. 1 while remaining open in both directions. The mineralization remains traceable from channel to channel and therefore demonstrates lateral continuity. The new mineralized zone is more silicified than known historical showings; also hematization, which is characteristic of the mineralized zones of the Cartwright area, is absent.

Stripping 25-02 located more than 650 metres west of the Cartwright area contains the Horse and Adam zones. This demonstrates the lateral continuity over at least 700 m of mineralization at the Cartwright area in an area that had not been explored prior to 2025. In addition, Strip 25-02 is located 600 metres SE of hole FL-23-265 which returned 3.9 g/t gold over 19 metres including 14.8 g/t gold over 4 metres (press release dated January 30, 2024). We are now able, thanks to its stripping, to demonstrate the thickening and thinning (socking) phenomena of the mineralized zones over more than 650 metres laterally.

The Methodology Used

The new phase of work made it possible to carry out six channels of approximately 10-15 metres in length on stripping 25-01 as well as 2 on stripping 25-02.

The samples collected are all 0.5 metres long and are connected to each other. Each of the samples averages 6 to 8 cm deep and the channel intersects perpendicularly with the mineralized zones. These zones are oriented approximately east-west and have a sub-vertical dip. The mineralization is associated with significant shear and is composed of pyrite-silica-hematite-rich bands associated with light-coloured alteration (sodium metasomatism). Surface alteration (weathering) of the gossan type (dissolution of pyrites, yellow surface).

The samples are then sent to the MSALABS analytical laboratory in Val-d'Or, Quebec where they were all analyzed using the Photon Assay^TM method.

The Results

Table 1. Main results obtained by channel sampling

Channel No.	Stripping No.	Intercept
Channel 25-01	25-01	1.4 g/t gold over 4.0 metres
Channel 25-02	25-01	0.5 g/t gold over 2.0 metres
Channel 25-04	25-01	0.8 g/t gold over 1.5 metres
Channel 25-01	25-02	0.3 g/t sur 7.0 metres
Channel 25-02	25-02	9.5 g/t d’or over 7.0 metres incl. 112.7 g/t d’or sur 0.5 metres

Pascal Hamelin, President and Chief Executive Officer commented: "The new channels completed confirm the continuity of the known mineralized zones over more than 650 metres. The areas remain open laterally to the east and to the west. Once again, with a minimal budget, we were able to significantly increase the footprint of the gold mineralization at surface. These new results will allow us to focus on our next phase of drilling.”

Future Developments

Abcourt is also pleased to announce that it will be present at the MUNICH MINING CONFERENCE on October 3 and 4, 2025 at the Olympic Hall Munich. During this conference, she will be able to present her excellent results as well as her new discoveries to the world of international investment.

Analytical Procedure

The 0.5-metre-long channel rock samples were shipped and analyzed by the MSALABS laboratory in Val-d'Or, Quebec using the Photon Assay^TM 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.
