Mayfair Gold Presents the Initial Results from the 2025 Grade Control Drilling Program at the Fenn-Gib Project

 Mayfair Gold Corp. (‘Mayfair’, ‘Mayfair Gold’, or the ‘Company’) (TSXV: MFG,OTC:MFGCF) (NSYE: MINE) is pleased to announce the initial results from the tight-spaced, grade control drilling program (‘Grade Control Program’ or ‘Program’) at the Fenn-Gib Project in Northern Ontario.

Nick Campbell, CEO of Mayfair Gold commented, ‘These initial results increase our confidence in the highest‑grade, early years of the Fenn‑Gib mine. While preliminary, they indicate potential for positive grade reconciliation, support the PFS early‑year assumptions, and are providing important data to advance project financing. Remaining assays are expected in Q1 2026.‘

The Grade Control Program comprised 56 diamond drill holes totaling approximately 4,200 metres. All holes were drilled vertically on a 10 m x 10 m spacing pattern to a target depth of 75 metres. The program was completed within the core of the Phase 1 starter pit and represents roughly one million tonnes of material anticipated to form part of the initial plant feed once construction is complete.

The objective of the program was to simulate grade control drilling and provide additional data to support delineation of the near‑surface portion of the orebody.  This news release reports results from 36 of the 56 drill holes; assays for the remaining holes are pending.

These results are considered interim in nature until all data from the complete Program is received and all QAQC results have been verified. No conclusions are being drawn currently regarding potential impacts on the overall mineral resource estimate or mine plan. In addition, the drill results disclosed herein were not incorporated into the Company’s 2026 Pre-Feasibility Study, published on 8 January 2026 and titled ‘Fenn-Gib Project: NI 43101 Technical Report and Pre-Feasibility Study.’ A copy of the technical report is available under the Company’s profile on SEDAR+.

According to Jean-Francois Metail, Mayfair’s Mineral Resource consultant, ‘In these interim results, the grade control program is already providing a high level of confidence in the block model within the starter pit. Just as importantly, it is generating critical, mining‑scale information on ore geometry, dilution, and potential ore loss that will be hugely useful as the operation moves toward start‑up and early production.‘

The objectives of the Grade Control Program were to:

• Validate near‑surface grade distribution and ore geometry using closely spaced grade‑control drilling
• Compare drilling results directly against the existing resource block model to assess local grade variability
• Improve definition of ore–waste boundaries to support efficient mining (i.e., reduce dilution and metal‑loss in both planning and operations)
• Increase confidence in grades and production during the ramp-up and early years of operations
• Contribute to broader strategy of de‑risking the Project following the PFS
• Enhance confidence for potential lenders as part of the Fenn-Gib project financing

(Interim) Grade Control Program Drill Data

The data presented provides a direct comparison between the intervals drilled during the Grade Control Program and those predicted by the current mineral resource block model.

Figure 1: Comparison of Grade Control and Block Model Results

How to read the table and data format:

• Each row shows one 75m vertical drill hole from the grade‑control program and compares what the assayed grades against the 2026 PFS resource block model grade along the same path. The data is summarized into 5‑metre composites to allow for direct comparison against the 5m resource model block height.
• Comparing the in-rock portion of the drilled holes (column (2)) against the average grade reported over the same interval in the resource block model (Column (3)), the results show a modest increase in average grade (1.47g/t vs 1.40 g/t).
• When applying a cut-off grade of 0.8 g/t, the program indicates higher grades over somewhat shorter lengths (column (4)) versus the block model (column (5)) (1,358m @ 2.21 g/t vs. 1,788m @ 1.68 g/t).
• It should be noted that, while the Grade Control Program reports higher average grades over shorter mineralized intervals above the 0.8 g/t Au cutoff, the resulting grade–length product is broadly consistent with that predicted by the block model.

No conclusions are to be drawn from the Program until final assay results from the remaining 20 of the 56 drill holes are received and all QA/QC procedures have been completed.

QA/QC

Mayfair Gold maintains a Quality Assurance/Quality Control (QA/QC) program aligned with NI 43‑101 requirements and industry best practices. NQ‑size surface drilling was carried out by Black Diamond Drilling of Matheson, Ontario, under the supervision of Mayfair Gold’s exploration team. The drill program includes detailed geological logging and systematic sampling of drill core at Mayfair’s secure facility in Matheson, Ontario.

Drill core selected for analysis was cut longitudinally using a diamond‑blade saw. One half of the core was retained in the core box for reference, and the other half was bagged, sealed, and prepared for shipment. Analytical work was completed by Swastika Laboratories Ltd. in Swastika, Ontario. Swastika Laboratories is accredited by the Canadian Association for Laboratory Accreditation Inc. (CALA) and meets the ISO/IEC 17025 standards for gold analysis by fire assay with gravimetric finish and fire assay with flame atomic absorption spectroscopy (FAAS) finish.

Samples were delivered directly to Swastika Laboratories by Mayfair personnel. Samples are crushed to minimum 80% passing 1,700 μm. Samples are then split to obtain a 300–500 g sample using a rotary divider. 300–500 g samples are pulverized to minimum 85% passing 74 μm. Gold assays were completed using a 30‑gram fire assay with FAAS finish. Samples returning gold grades greater than 10 g/t were re‑assayed using a 30‑gram fire assay with gravimetric finish. As part of Mayfair’s QA/QC protocol, one certified reference material (CRM), one coarse blank, and one coarse duplicate sample were inserted into the sequence of every 25 samples. Routine third‑party check assays are also performed.

All holes in the program were drilled fully vertical (-90° dip) and true thickness is not estimated.
