**Mayfair Gold Appoints Drew Anwyll, P.Eng., as CEO**

<br>**Toronto, Ontario – May 4, 2026** – Mayfair Gold Corp. (**"Mayfair"**, **"Mayfair Gold"**, or the **"Company"**) (TSXV: MFG, NYSE American: MINE) is pleased to announce the appointment of Drew Anwyll, P.Eng., formerly Chief Operating Officer of the Company, as Chief Executive Officer of the Company, effective immediately. Nick Campbell, current Chief Executive Officer, will be stepping down and departing the Company.

**Darren McLean, Chair of the Board,** states, "*Mayfair is on the path to build and operate the Fenn-Gib Gold Project. By appointing Drew, an accomplished operator, as CEO, the Company is well positioned to execute on this plan. The Board would like to thank Nick for his leadership and contributions, including his work in elevating the Fenn-Gib story, progressing the NYSE American listing, and advancing us to this point. We wish him well in his future endeavours.*"

*"Mayfair is advancing with Fenn-Gib project designs and moving into the approvals phase with momentum and a team built to deliver,"* said **Drew Anwyll, P.Eng.,** incoming CEO. *"I'm proud of the culture of excellence, ownership, and execution that exists within the organization. Our focus is to move Fenn-Gib toward production on an accelerated path, with discipline. I look forward to stepping into this role and am committed to further strengthening relationships with Indigenous partners, local communities, government agencies, and all stakeholders as we advance together."*

**Nick Campbell, outgoing CEO,** said, "*My role at Mayfair was to help shape the strategy with the Board, begin telling the story, and bring the team together to execute on that vision. That foundation is now firmly in place. The team Drew has assembled stands out in any project development organization. The culture Drew has fostered in such a short time is remarkable, and I look forward to watching Mayfair continue to advance.*"

**Biography: Drew Anwyll, P.Eng., B.Eng., M.Eng.**

**Chief Executive Officer, Mayfair Gold Corp.**

Drew 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 track 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 Pre-Feasibility 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 Limited** (2020–2025) 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, multi-agency 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 Corporation** (2011–2018), 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:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;·**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.

------

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;·**Strategic optimization:** He led long-term technical planning and resource delineation that established the mine as a "tier-one" global asset, which eventually led to its successful C$4.9 billion acquisition and integration into Agnico Eagle's portfolio.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;·**Operational excellence:** His focus on high-capacity open-pit mining and operational efficiency at Detour Lake provides Mayfair with the executive oversight needed to de-risk 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.
