• Improved Copper Grade Following Overlimit Assays: Final results from hole 1274-17-269W3 returned an updated intercept of 4.46% CuEq over 21.1 metres (previously 3.65% CuEq), within a broader interval of 1.8% CuEq over 69.0 metres (previously 1.55% CuEq), starting at a downhole depth of 932 metres. These enhanced grades further highlight the strength of the copper-gold mineralization at the B26 Deposit.

• Torque to Rising Gold and Silver Prices: The B26 Deposit benefits from significant gold and silver credits that enhance the overall copper-equivalent grade. Using spot metal prices, the headline intercept from hole 1274-17-269W3 increases to 5.89% CuEq over 21.1 metres ⁴ , reflecting the contribution of a 1.14 g/t gold credit. This highlights the deposit's strong leverage to precious metal prices and its potential to deliver enhanced value in a rising gold and silver price environment.

• Phase 3 Drill Program Expanded to 20,000 Metres: Based on the success of hole 269W3 and encouraging visual mineralization observed in subsequent holes, Abitibi Metals has expanded the ongoing Phase 3 program to 20,000 metres.

• Three Rigs Advancing Under Phase 3: The drill campaign continues with three active rigs, utilizing IMDEX directional drilling technology. Phase 3 is on track for completion by the end of November.

London, Ontario--(Newsfile Corp. - October 9, 2025) - Abitibi Metals Corp . (CSE: AMQ) (OTCQB: AMQFF) (FSE: FW0) (" Abitibi" or the "Company ") is pleased to announce the expansion of its Phase 3 drill program at the B26 polymetallic deposit in Québec to 20,000 metres, alongside the release of final assay results from hole 1274-17-269W3. Drilling continues to successfully intersect mineralization outside of the current Mineral Resource Estimate ("MRE"), confirming the potential to expand the mineralized footprint.

Abitibi currently holds a 50% interest in the B26 Deposit and retains the option to earn an additional 30% from SOQUEM Inc. ("SOQUEM"), a subsidiary of Investissement Québec (see November 16, 2023 News Release ).

Three drill rigs are active on site, focused on high-priority expansion targets along the western and down-plunge extensions of the B26 system. Final overlimit copper assays from hole 1274-17-269W3 have returned an upgraded intercept of 4.46% CuEq over 21.1 metres, representing an increase of 22% from the previously reported 3.65% CuEq. This updated result further underscores the strength and continuity of the copper-gold system at B26.

Hole 269W3 represents one of the most robust intercepts to date in the western plunge, validating the high-grade growth potential of this zone, supported by a meaningful gold credit. The hole successfully tested a large gap in the current drill pattern, located approximately 80 metres down-dip from hole 1274-17-260, which returned 2.56% CuEq over 10.0 metres within a broader 1.26% CuEq over 28.5 metres. The comparison suggests increasing grade and width with depth.

Based on this world-class intercept and consistently strong visual mineralization observed in follow-up drilling, the Company has expanded the Phase 3 program from its original scope to 20,000 metres, aimed at unlocking further growth in the high-grade western plunge area.

"We are extremely encouraged by the final results from 269W3, which demonstrate world-class copper grades," said Jonathon Deluce, CEO of Abitibi Metals. "As a result, we are expanding the Phase 3 drill program through the end of the year to 20,000 metres, with a focus on the high-grade western plunge of the system, where we are also seeing strong gold enrichment. This phase will include aggressive step-out drilling - up to 500 metres from the current B26 Resource - to test the broader expansion potential and to vector in on the potential source of this copper-gold stringer system."

Note 1: The intercepts above are not necessarily representative of the true width of mineralization. The local interpretation indicates core length corresponding generally to 40 to 70% of the mineralized lens' true width.

Note 2: Copper equivalent values calculated using metal prices of $4.00/lb Cu, $1.50/lb Zn, $20.00/ounce Ag and $2,500/ounce Au. Recovery factors were applied according to SGS CACGS-P2017-047 metallurgical test: 98.3% for copper, 90.0% for gold, 96.1% for zinc, 72.1% for silver.

Note 3: Intervals are generally composited starting with a 0.1% CuEq cut-off and between 0.6% CuEq cut-off grade for the "including" intervals, allowing for up to 3 consecutive samples below cut-off grade.

Note 4: Spot copper equivalent values calculated using metal prices of $5.00/lb Cu, $1.35/lb Zn, $48.00/ounce Ag and $3,900/ounce Au. Recovery factors were applied according to SGS CACGS-P2017-047 metallurgical test: 98.3% for copper, 90.0% for gold, 96.1% for zinc, 72.1% for silver.
