Biography: Drew Anwyll, PEng, BEng, MEng

Chief executive officer, Mayfair Gold

Mr. Anwyll is a seasoned mining executive and professional engineer with more than 30 years of experience in the development, construction and operation of large-scale gold assets across Canada and internationally, and has previously served as a director for several publicly traded mining entities. Known as a "mine builder" with a proven record of navigating complex regulatory landscapes, Mr. Anwyll's appointment as CEO marks a strategic development for Mayfair Gold as it advances the Fenn-Gib gold project toward production.

His career is defined by his ability to bridge the gap between technical feasibility and operational reality, particularly within the Ontario mining jurisdiction. Most recently, Mr. Anwyll served as Mayfair's chief operating officer, where he spearheaded the 2026 prefeasibility study (the PFS) and the commencement of front-end engineering and design (FEED) for the Fenn-Gib project.

Expertise in provincial permitting and regulatory success

Mr. Anwyll's most recent success at Generation Mining Ltd. (2020 to 2025) is directly applicable to Mayfair's objective of getting into Ontario's One Project, One Process (1P1P) permitting framework. As chief operating officer at Generation Mining, he was the primary architect of the technical and environmental strategy for the Marathon palladium-copper project.

Under his leadership, the Marathon project successfully navigated a rigorous joint federal and provincial review panel for its environmental assessment, receiving government approval in late 2022, and further advanced the project through the permitting process. His strong working relationships with the Ontario Ministry of Energy and Mines and the Ministry of Environment, Conservation and Parks were instrumental in securing key construction permits. This experience with interdisciplinary, multiagency requirements is a critical asset as Mayfair seeks to streamline its own approval timelines under Ontario's 1P1P initiative, which emphasizes concurrent provincial reviews to accelerate projects.

A legacy of large-scale production: the Detour Lake benchmark

Prior to his tenure at Generation Mining, Mr. Anwyll spent nearly a decade at Detour Gold Corp. (2011 to 2018), where he held senior executive roles including senior vice-president of technical services and interim COO. He was a cornerstone of the leadership team that transformed the Detour Lake project from a massive resource on paper into one of Canada's largest and most efficient gold mines.

His accomplishments at Detour Lake are particularly relevant to the Fenn-Gib project's open-pit profile:

• Construction through ramp-up: He contributed through construction and oversaw the initial start-up and operational scale-up of the Detour Lake mine, managing throughput that exceeded 65,000 tonnes per day at the processing plant and more than 200,000 tonnes per day in the mining operation.
• Strategic optimization: He led long-term technical planning and resource delineation that established the mine as a Tier 1 global asset, which eventually led to its successful $4.9-billion acquisition and integration into Agnico Eagle's portfolio.
• Operational excellence: His focus on high-capacity open-pit mining and operational efficiency at Detour Lake provides Mayfair with the executive oversight needed to derisk the Fenn-Gib construction phase.

Vision for Mayfair Gold

As CEO, Mr. Anwyll is focused on executing a disciplined transition from exploration to production. His strategy integrates technical design elements with a modern permitting framework, ensuring that Mayfair advances the Fenn-Gib gold project efficiently within the Timmins mining camp. His technical rigor, combined with a decade of specific experience in Northern Ontario's permitting, indigenous engagement and labour markets, positions Mayfair Gold to deliver on its promise of becoming Ontario's next significant gold producer.

Mr. Anwyll holds a bachelor's and a master's degree in mining engineering from McGill University. He is a registered professional engineer in Ontario.
