Mayfair says Fenn-Gib hosts a 4.3-million-ounce indicated gold resource and a 1-million-ounce probable mineral reserve. The 2026 pre-feasibility study outlines C$450 million in initial development capital and a 2.7-year base-case payback, and describes potential cumulative free cash flow of US$896 million over the first six years of production at a US$3,100-per-ounce gold price.

Mayfair Gold Corp. announced a proposed financing package of up to C$310 million to support development, construction, commissioning and start-up of its 100%-owned Fenn-Gib Gold Project in Northern Ontario. The package combines a C$10 million strategic equity investment under a subscription agreement with a proposed C$300 million project finance facility with Macquarie Bank Limited.
The equity investment is priced at C$4.26 per share, a 10% premium to the five-day volume-weighted average trading price on and including September 30, 2026, subject to acceptance by the TSX Venture Exchange. The facility term sheet is non-binding; Macquarie would act as Mandated Lead Arranger, Agent and Sole Underwriter.

Macquarie may, in consultation with Mayfair Gold, arrange participation by additional lenders or risk participants for a minimum of 30% of the facility amount. The proposed facility and related transactions remain subject to due diligence, including review by an independent engineer, definitive documentation and customary conditions precedent.
Mayfair Gold Corp. entered into a subscription agreement for a proposed C$10 million strategic equity investment by Macquarie Bank Limited at C$4.26 per common share, and an engagement letter and non-binding term sheet for a proposed C$300 million project finance facility.
