Canadian gold development company Mayfair Gold Corp. (TSXV: MFG | NYSE American: MINE) has announced a significant strengthening of its technical leadership team, appointing Adree DeLazzer, P.Geo as Vice President, Exploration and Jean François Métail as Vice President, Mineral Resource Management. Both appointments arrive at a pivotal moment — as the company advances its flagship Fenn-Gib Gold Project in Northern Ontario through permitting and detailed engineering, with construction targeted for 2028 and initial production in 2030.
Adree DeLazzer, P.Geo — VP Exploration
Adree DeLazzer is a professional geologist with 20 years of experience in mineral exploration and mine-site geology across Canada, with deep expertise in gold systems across the Abitibi Greenstone Belt — one of the world's most prolific gold-producing regions. Her career encompasses some of the most significant gold projects and discoveries in Canadian mining history.
Most recently, DeLazzer served as VP Exploration at Northern Superior Resources Inc., where she led corporate exploration strategy across a large, district-scale land position in the Chibougamau Gold Camp, overseeing multi-million-dollar exploration programmes. She was instrumental in advancing a camp-scale consolidation strategy and contributed directly to the company's growth and its ultimate acquisition by IAMGOLD Corporation.
Earlier in her career, DeLazzer held senior technical roles with Kirkland Lake Gold Ltd. and Detour Gold Corporation, leading exploration at the Detour Lake Mine — now the largest gold mine in Canada — supporting significant resource expansion and contributing as part of the 58N discovery team.
In her new role, DeLazzer will lead exploration activities across Mayfair Gold's expanded land package — including the recently acquired South Block and Plato properties, which increased the company's total land position by more than 65%. Exploration will focus on defining and prioritising 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.
"The Fenn-Gib Project is a well-defined asset, and the broader land package presents a compelling opportunity to evaluate additional targets along the Destor–Porcupine Deformation Zone. I look forward to working with the team on the ground to advance exploration programmes focused on defining and prioritising structurally controlled high-grade gold targets across the property."— Adree DeLazzer, P.Geo, VP Exploration, Mayfair Gold
Jean François Métail — VP Mineral Resource Management
Jean François Métail is a seasoned geo-scientist with more than 30 years of global experience in exploration, resource development, reserve strategy, and production reconciliation. His career includes senior technical roles at two of the world's most prominent gold mining companies, bringing deep expertise in resource modelling, QA/QC systems, grade control, and reserve conversion that directly supports the development stage work underway at Fenn-Gib.
Métail spent 16 years at Barrick Gold, serving as Director of Geology and Reserve Strategy within the corporate Operations Support group. His responsibilities encompassed reserve stewardship, resource-to-reserve conversion, and establishing best practices for geological modelling, reconciliation, and QA/QC across Barrick's global portfolio — spanning operations in Mexico, Chile, Quebec, and Ontario.
From 2012 to 2017, Métail held senior roles at Detour Gold, including VP Exploration and Mineral Resources Management — where he oversaw resource growth, geological interpretation, and technical support for the Detour Lake Gold Mine. Many of the systems he built there continue to underpin operations at Canada's largest gold mine today. He subsequently served as President and Senior Technical Advisor to Blue Thunder Mining, supporting exploration strategy in the Abitibi region. Métail holds a B.Sc. from the Université de Montréal and completed a Citation Program in Geostatistics at the University of Alberta.
Having previously supported Mayfair Gold in a consulting capacity, Métail transitions into his full-time role with an existing depth of knowledge of the project. His expanded mandate covers geological oversight for Fenn-Gib, resource modelling, and the technical de-risking work critical to advancing the project through development and into operations.
"We are very pleased to welcome Adree to the Mayfair team. Her background in leading exploration programmes, combined with her experience in camp-scale consolidation and strategic development, will be important as we continue to evaluate the broader potential of our land package."— Drew Anwyll, P.Eng, CEO, Mayfair Gold
Why These Appointments Matter: Building for Development
The simultaneous appointment of two highly experienced technical leaders signals a deliberate and coordinated effort by Mayfair Gold to build the internal expertise required to advance Fenn-Gib from its current development stage through to production — while simultaneously growing its exploration pipeline for the future.
DeLazzer brings the near-mine exploration and camp-scale discovery experience needed to unlock the full potential of a land package that has grown significantly with the addition of the South Block and Plato properties. Métail brings the resource-to-reserve conversion and geological systems expertise that transforms exploration success into bankable ounces — an essential technical function as the project advances toward construction finance and operational readiness.
Together, their combined experience at Detour Gold — Canada's largest operating gold mine — provides direct, first-hand institutional knowledge of what it takes to develop, model, and operate a large-scale Abitibi gold project from early stage through to sustained production.
