VANCOUVER, BC, Oct. 14, 2025 /PRNewswire/ - Mayfair Gold Corp. ("Mayfair", "Mayfair Gold" or the "Company") (TSXV: MFG); (OTCQX: MFGCF) is pleased to announce that it has filed a technical report prepared in accordance with National Instrument 43-101 - Standards of Disclosure for Mineral Projects for the Fenn-Gib Gold Project located in the Timmins Gold District in Northeastern Ontario. The report is titled "National Instrument 43-101 Technical Report - Mineral Resource Estimate Update Fenn-Gib Project, Ontario, Canada". A copy of the technical report is available under the Company's profile on SEDAR+.
The prior NI 43-101 Technical Report for the Fenn-Gib project was filed on July 26, 2023, with an effective date of April 6, 2023. The effective date of this updated mineral resource estimate is September 3, 2024. The assay cut-off date for drill holes included in the mineral resource was April 30, 2024. The gold price in this updated technical report was increased from US$ 1,765/oz Au (used in the prior technical report) to US$ 2,000/oz Au but all other costs and recoveries are unchanged. The increase in metal price resulted in lowering the cut-off grade from 0.4 g/t Au to 0.3 g/t Au and increased the footprint of the resource pit shell. In addition, this new technical report adds further detail relating to the Mineral Processing and Metallurgical Testing completed to date as follow-on from the news release dated 27 May 2025. This mineral resource and metallurgical results will support the pre-Feasibility Study that is currently underway and expected to be released later in 2025.
This technical report was prepared by T. Maunula & Associates Consulting Inc. and Haggarty Technical Services Corporation.
