Highlights:
- Excellent High-Grade and Wide Intercept in the Western Down-Plunge Zone:
- Hole 1274-26-378W1 intersected 1.48% CuEq over 46.7 m (1.33% Cu, 0.13 g/t Au) starting at 946 m depth, including a higher-grade interval of 4.04% CuEq (3.63% Cu, 0.37 g/t Au) over 14 m.
- Confirms High-Grade continuity by 50 m along the eastern extension of the Western Down-Plunge, supporting resource growth through a potential increase in tonnage and grade in this area of the resource.
- High-grade assay results should positively impact the block model in this area, which is currently estimated at under 2% CuEq.
London, Ontario – May 27, 2026 – Abitibi Metals Corp. (CSE: AMQ) (OTCQB: AMQFF) (FSE: FW0) (“Abitibi” or the “Company”) is pleased to report another exceptional wide and high-grade copper-gold intercept from its ongoing drill program at the B26 Polymetallic Deposit (“B26” or the “Deposit”) in Québec. The Company’s resource improvement drilling campaign outperforms expectations, confirming excellent grade continuity. Abitibi currently holds an 80% interest in the B26 Project, with SOQUEM Inc., a subsidiary of Investissement Québec, holding the remaining 20% (see news release dated March 12, 2026).
Jonathon Deluce, CEO of Abitibi Metals, commented: “Our 2026 drill program is progressing well, with results continuing to align with and validate our disciplined, high-impact capital allocation strategy at B26. Hole 378W1 is a strong example of this approach, successfully achieving multiple objectives within a single drill hole. Notably, it confirms a 50-metre eastern extension of the High-Grade Western Down-Plunge—one of the most significant discoveries from last year’s program. This hole also contributes to the delineation of the indicated resource drill grid and delivered both greater width and higher grade than the current block model in this area, supporting continued organic resource growth at B26 and reinforcing our confidence in grade continuity across the deposit.”
Discussion of Results:
Holes 1274-26-378 and 378W1 further underscore the Western Down-Plunge as a highly prospective and priority growth corridor within the B26 Deposit. Positioned approximately 50 metres from hole 269W6, these drill holes successfully targeted both the up-dip projection and eastern extensions of this high-grade zone. The current drill spacing is expected to support the conversion of this sector into the indicated resource category, marking a significant step forward in resource confidence.
The results strongly confirm the continuity and robustness of the high-grade mineralization, reinforcing the expansion potential of the system. Collectively, these two holes are expected to have a meaningful positive impact on the high-grade domain within the block model, further enhancing the overall resource profile.
Mineralization is typical of a well-developed copper stringer system, characterized by intense dark chlorite alteration and evidence of remobilization and deformation, often associated with thicker, more massive sulphide sections. These geological features are consistent with, and highly characteristic of, the Western Down-Plunge Zone, supporting the interpretation of a dynamic and evolving high-grade corridor with considerable upside.

Note 1: The intercepts above are not necessarily representative of the true width of mineralization. The local interpretation indicates that the mineralized lens’ true width generally corresponds to 60% to 80% of the core length.

QAQC
The core logging and QAQC protocol program was run and supervised by the Company technical team. The drill core was split in half, sent to AGAT Laboratories Ltd. All sample preparation takes place in Val-d’Or, all fire assay takes place in Thunder Bay and all 4-Acid digestion and multi element analysis takes place in Calgary. Prepared samples are fused using accepted fire assay techniques, cupelled and parted in nitric acid and hydrochloric acid. Sample splits of 30 g are routinely used though 50 g may also be used (AGAT Code 202 551). 0.2 g of prepared samples are digested with a series of acids (HClO4, HF, HCL and HNO3) at a temperature of ~200oC until incipient dryness. It is then heated with HNO3 and HCl, then diluted to 12 mL with de-ionized water. While very aggressive, the solubility of some elements can be dependent on the mineral species present and as such, data reported from the 4-Acid digestion should be considered as representing only the leachable portion of a particular analyte. Some elements show poor recovery due to volatilization (B, As, Hg). PerkinElmer 7300DV/8300DV ICP-OES and Agilent 5900 ICP-OES instruments are used in the analysis. Inter-Element Correction (IEC) techniques are used to correct for any spectral interferences. Blanks, sample replicates, duplicates, and internal reference materials (both aqueous and geochemical standards) are routinely used as part of AGAT Laboratories’ quality assurance program. AAS instruments are used in the analysis.

Forward-looking statement:
This news release contains certain statements, which may constitute “forward-looking information” within the meaning of applicable securities laws. Forward-looking information involves statements that are not based on historical information but rather relate to future operations, strategies, financial results or other developments on the B26 Project or otherwise. Forward-looking information is necessarily based upon estimates and assumptions, which are inherently subject to significant business, economic and competitive uncertainties and contingencies, many of which are beyond the Company’s control and many of which, regarding future business decisions, are subject to change. These uncertainties and contingencies can affect actual results and could cause actual results to differ materially from those expressed in any forward-looking statements made by or on the Company’s behalf. Although Abitibi has attempted to identify important factors that could cause actual actions, events or results to differ materially from those described in forward-looking information, there may be other factors that cause actions, events or results to differ from those anticipated, estimated or intended. All factors should be considered carefully, and readers should not place undue reliance on Abitibi’s forward-looking information. Generally, forward-looking information can be identified by the use of forward-looking terminology such as “expects,” “estimates,” “anticipates,” or variations of such words and phrases (including negative and grammatical variations) or statements that certain actions, events or results “may,” “could,” “might” or “occur.” Mineral exploration and development are highly speculative and are characterized by a number of significant inherent risks, which may result in the inability of the Company to successfully develop current or proposed projects for commercial, technical, political, regulatory or financial reasons, or if successfully developed, may not remain economically viable for their mine life owing to any of the foregoing reasons, among others. There is no assurance that the Company will be successful in achieving commercial mineral production and the likelihood of success must be considered in light of the stage of operations.
