About Mayfair Gold

Mayfair Gold is a Canadian development-stage gold company focused on advancing the 100%-owned 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”)¹ 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, highlighting the optionality and scalability provided by the deposit. The PFS also outlines the potential to develop Fenn-Gib into a new Canadian gold producer, with initial development capital of C$450 million, a base-case payback period of 2.7 years, and cumulative free cash flow² of US$896 million over the first six years of production based on a US$3,100/oz gold price. The Company is advancing permitting activities, detailed engineering, and stakeholder engagement with the goal of starting construction in 2028 with initial production in 2030. The Company also remains focused on exploration around the broader land package with the goal of enhancing mineral resource scale and growth opportunities.
