Company profile
Mayfair Gold is a Canadian development-stage gold company focused on advancing the 100% controlled Fenn-Gib Project in the Timmins region of Northern Ontario. Fenn-Gib hosts a 4.3 million ounce indicated mineral resource of gold (181.3Mt at an average grade of 0.74 g/t) and the expected strategy outlined in the 2026 Pre-Feasibility Study (the “PFS”) is to develop the project under the provincial permitting process, targeting the higher-grade 1 million ounce probable mineral reserve (25.1Mt at an average grade of 1.29g/t) sitting near-surface first with optionality to target the broader resource in the future. The PFS outlines initial development capital of C$450 million, a base-case payback period of 2.7 years, and cumulative free cash flow of US$896 million over the first six years of production based on a US$3,100/oz gold price. The Company is run by a team that was instrumental in building and operating the Detour Lake gold mine and securing permits for Generation Mining's Marathon Project. The company expects to enter Ontario's streamlined permitting process (1P1P) in September and is currently undergoing detailed engineering and stakeholder engagement with the goal of starting construction in 2028 and production in 2030. The company also remains focused on exploration around the broader land package along the Porcupine Destor Fault Zone with the goal of enhancing mineral resource scale and growth opportunities.
