Mayfair Gold puts a plan in place to mine near Matheson by 2030

Mayfair Gold is on the permitting path to put its Fenn-Gib Gold Project, outside Matheson, into production within five years.

The Vancouver company delivered an update on its plans and outlook for 2025, April 5.

Fenn-Gib is Mayfair’s only asset and contains an indicated gold resource of 4.3 million ounces. The average grade is 0.74 grams per tonne within 181.3 million tonnes of ore.

The project is 21 kilometres west of Matheson. Highway 101 runs by the property.

On Mayfair’s agenda for 2025 is to do all the necessary prep work toward entering the provincial approvals and permitting process, the company said in a news release. A prefeasibility study of what a mine will look like is expected out by year’s end.

Mayfair envisions a scenario of Fenn-Gib as open-pit mine capable of processing 4,800 tonnes of ore a day. The strategy is to begin mining operations with a high-grade starter pit to generate some revenue and reduce its up-front capital costs at startup.

The plan is put Fenn-Gib into production by 2030.

Mayfair recently bolstered the team by adding Drew Anwyll as chief operating officer. He filled the same role with Generation Mining at its Marathon copper-palladium project. Before that, he was instrumental in the development and startup of the Detour gold pit, north of Cochrane.

Metallurgical test work is being done to better understand how the ore’s physical and chemical properties and how it will respond to processing. Those results will factor into the design of the processing flow sheet, which is a road map that lays out all the various stages and functions of the milling equipment used and how the ore will be processed.

The company has been collecting environmental baseline data since 2022. To ensure the provincial permitting process runs smoothly, Mayfair said it’s reviewing all this data to determine if any work needs to be done.

Mayfair pledges an “advanced” engagement process with Indigenous communities in the area to share its plans on the mine’s design, potential spinoff economic benefits, and mitigation strategies to reduce any adverse effects from mining on the environment, health and social disruption. 

"The 2025 work program is designed to support the provincial permitting process and ensure that the design and execution of the development adheres to high environmental standards,” said Mayfair CEO Nick Campbell in a statement. “With the proper planning and discipline, Mayfair is preparing to begin the Ontario provincial environmental assessment process in 2025.”
