Selected Financial Data

The following selected financial data is summarized from the Company's financial statements and related notes thereto (the "Financial Statements") for the three and nine months ended September 30, 2024 and 2023.

2024 Outlook

In the first quarter of 2024, the Company announced the commencement of a pre-feasibility study on the Fenn-Gib project. The study will build further on the metallurgical, geotechnical, hydrogeology, and environmental evaluations completed to date to develop a clearly defined project description in support of a potential environmental assessment. Mayfair Gold has engaged Richard Klue as Vice President of Technical Services to manage the entire Fenn-Gib project, who has included AGP Mining Consultants, Halyard Inc, Terracon Geotechnique and Environmental Applications Group (EAG) as lead engineers and scientists of a multi-disciplinary group to deliver the pre-feasibility study. The pre-feasibility study is a major milestone towards the development of the Fenn-Gib project.

About the Fenn-Gib Project

The Fenn-Gib Project comprises two property packages, referred to as the Fenn-Gib North and South Blocks, which are separated by approximately three kilometers. The Fenn-Gib Deposit is located on the North Block along the regional Contact Fault, an east-west to south-east trending shear zone on the Pipestone Fault, which is interpreted to be a splay off the Porcupine-Destor Fault. The Fenn-Gib Deposit hosts significant concentrations of gold mineralization within two zones: (i) the Main Zone, and (ii) the Deformation Zone. These two zones overlap completely. A third zone of mineralization, known as the Footwall Zone, is located approximately 100 meters to the northwest of the Fenn-Gib Deposit. A fourth zone of mineralization, known as the Contact Zone, is located at depth below the current pit-constrained resource.

September 3, 2024 Fenn-Gib Resource Estimate by Category Using 0.30 g/t Au Cut-Off

All mineral resources have been estimated in accordance with Canadian Institute of Mining and Metallurgy and Petroleum definitions, as required under NI 43-101. Ounce (troy) = metric tonnes x grade / 31.10348. All numbers have been rounded to reflect the relative accuracy of the estimate

QA/QC Controls

Mayfair employs a QA/QC program consistent with NI 43-101 and industry best practices. Surface drilling was conducted by Major/Norex Drilling of Timmins, Ontario and was supervised by the Mayfair exploration team. Mayfair's drill program includes descriptive logging and sampling of the drill core for analysis at Mayfair's secure facility located in Matheson, Ontario. Sampled drill core intervals were sawn in half with a diamond blade saw. Half of the sampled core was left in the core box and the remaining half was bagged and sealed. Mayfair utilizes accredited laboratories that include, Activation Laboratories Ltd. (Actlabs) and AGAT Laboratories Ltd. (AGAT) both located in Timmins, Ontario. Mayfair personnel transport the samples directly and deliver to Actlabs, and samples are collected by AGAT personnel directly from Mayfair's secure core logging facility in Matheson, Ontario. Gold was analyzed by 30-gram fire assay with AA-finish. Certified reference material (CRM) standards and coarse blank material are inserted every twenty-five samples. Mayfair completes routine third-party check assays.

Qualified Person

Tim Maunula, P. Geo., of T. Maunula & Associates Consulting Inc, is a qualified person for the purposes of National Instrument 43-101 and was responsible for the completion of the updated mineral resource estimation.
