Mayfair's Chief Executive Officer Nicholas Campbell commented,

"Dear Stakeholders,

I am pleased to provide an update on our progress at Mayfair Gold and the Fenn-Gib Gold project in Northern Ontario. In Q3 2025, Mayfair completed a $40 million LIFE Offering which secured substantial funding to support the Mayfair Gold and advance the Fenn-Gib gold project through permitting, detailed engineering and community engagement. The company continued to advance work on the Pre-Feasibility Study (" PFS ") for a 4,800 tpd open pit operation targeting the high-grade near surface zone of mineralization at Fenn-Gib.

The Company commenced a confidence drilling program in October 2025, which will give Mayfair more data to better define waste to ore boundaries and improve confidence in the grade profile for the mine over the first several years of production. Results of the drill program are expected to be available in Q1 2026. Mayfair continues to focus on derisking the Fenn-Gib gold project. The PFS remains on track to be completed in Q4 2025 with formal Provincial permitting activities expected to commence at the start of 2026.

With a strong balance sheet, an established team to advance the Fenn-Gib Project, execute the construction of the mine and with the upcoming PFS to illustrate the potential economics of 4,800 tpd open pit targeted the high-grade zone at Fenn-Gib, Mayfair Gold is very excited about the prospects for the Company as we unlock the value of Fenn-Gib and work to advance Mayfair Gold into a new Canadian Gold producer."
