MINE · Mayfair Gold Corp.

Mayfair Gold Corp. announced the appointment of Adree DeLazzer as Vice President, Exploration and Jean François Métail as Vice President Mineral Resource Management, effective May 13, 2026. Ms. DeLazzer, a professional geologist with 20 years of experience in mineral exploration across Canada, most recently served as VP Exploration at Northern Superior Resources Inc., where she led corporate exploration strategy and oversaw multi-million-dollar programs. She will lead exploration activities across Mayfair's expanded land package, including the South Block and recently acquired Plato properties, which increased the Company's land position by over 65%. The exploration focus will be on defining structurally controlled gold targets along the Destor-Porcupine Deformation Zone and advancing near-mine opportunities to support the long-term growth of the Fenn-Gib Project. Mr. Métail, a seasoned geoscientist with over 30 years of global experience, previously held senior roles at Barrick Gold and Detour Gold. He will oversee resource modelling, QA/QC systems, and technical de-risking as the Fenn-Gib Project advances through development and into operations. These appointments strengthen Mayfair's technical leadership as it progresses the Fenn-Gib Project, which is supported by a 2026 Pre-Feasibility Study outlining 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 at a US$3,100/oz gold price. The Company is advancing permitting and detailed engineering with the goal of starting construction in 2028 and initial production in 2030.
