Mayfair files NPS to advance Fenn‑Gib toward Ontario mine‑in‑production

Vancouver filing advances Fenn‑Gib toward Ontario mine status

Main development: Ministry notice and project registration

Mayfair Gold is formally submitting a Notice of Project Status (NPS) for its 100%‑owned Fenn‑Gib gold project in the Timmins mining district, registering the project with the Province of Ontario and notifying the Ministry of Energy and Mines of its intent to advance Fenn‑Gib toward “mine in production” status under the Ontario Mining Act. The filing signals that Mayfair is moving from study phase toward regulatory permitting, positioning the project within Ontario’s modernized permitting framework and establishing an official pathway for future construction and operating approvals.

The NPS frames a staged program of work that continues detailed engineering, environmental assessment and socioeconomic studies while expanding stakeholder consultation. Mayfair is emphasizing ongoing, meaningful engagement with the Apitipi Anicinapek Nation and other local and regional Indigenous communities as part of its permitting and permitting-readiness activities, and is carrying out technical work intended to de-risk the project ahead of licence applications and financing discussions.

By notifying the ministry, Mayfair aims to anchor timelines for the next phases of development and to demonstrate regulatory and community alignment as it pursues mine‑in‑production status. The company positions the NPS as a commitment to responsible project planning and transparent engagement, steps it says are necessary to support future construction approvals and to keep the project on the targeted schedule toward construction and production.

Economic case and schedule

Mayfair’s prefeasibility study underpins the filing, outlining a potential development with initial capital of about 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 based on a US$3,100/oz gold price. The company is targeting the start of construction in 2028 and initial production in 2030, contingent on further permitting, financing and licence approvals.

Technical review and next steps

The technical content of the NPS is reviewed and approved by Drew Anwyll, P.Eng., Mayfair’s chief operating officer and a qualified person under NI 43‑101. Mayfair is continuing detailed engineering, environmental and socioeconomic work while seeking to secure financing, regulatory approvals and the licences needed to meet its proposed 2028–2030 timetable.
