Mayfair Gold lines up C$310m Macquarie financing pathway for Fenn-Gib

Mayfair Gold Corp. (TSXV: MFG; NYSE American: MINE), the Canadian gold developer advancing the Fenn-Gib Gold Project near Timmins in northern Ontario, has agreed a financing framework with Macquarie Bank Limited that could provide up to C$310 million through a combination of equity and project debt. Macquarie has committed C$10 million of equity at C$4.26 per share, while a separate non-binding term sheet contemplates a C$300 million senior project-finance facility.

The proposed debt would cover a substantial portion of Fenn-Gib’s estimated C$450 million initial development capital. Macquarie would act as mandated lead arranger, agent and sole underwriter, while retaining the ability to syndicate at least 30% of the facility to other lenders or risk participants.

Why is the Macquarie financing important for Mayfair Gold?

Funding is often the point at which apparently attractive mining studies collide with market reality. A project can have a sizeable gold resource and positive net present value but remain stranded if its developer cannot assemble several hundred million dollars of construction capital on acceptable terms.

Mayfair Gold’s proposed C$300 million facility addresses much of that problem. The 2026 pre-feasibility study estimated Fenn-Gib’s initial capital requirement at C$450 million, meaning the Macquarie debt package could theoretically cover roughly two-thirds of initial construction spending before other equity, cash or financing sources are considered.

The C$10 million strategic equity component is also notable because Macquarie agreed to invest at C$4.26 a share, approximately 10% above the five-day volume-weighted average price disclosed by Mayfair Gold. Equity priced at a premium sends a different signal from a distressed capital raise below market.

What are the economics of the Fenn-Gib Gold Project?

Fenn-Gib hosts an indicated mineral resource of approximately 4.3 million ounces of gold contained within 181.3 million tonnes grading about 0.74 grams per tonne. The current development strategy focuses initially on a higher-grade probable reserve of approximately one million ounces contained within 25.1 million tonnes grading 1.29 grams per tonne.

The pre-feasibility study, using a base-case US$3,100-per-ounce gold price, estimated an after-tax net present value at a 5% discount rate of C$652 million and a payback period of approximately 2.7 years. Mayfair Gold also projected about C$896 million of cumulative free cash flow during the first six years of production.

Operating estimates included life-of-mine cash costs of around US$1,203 per ounce and all-in sustaining costs of approximately US$1,292 per ounce. Those figures create potentially substantial margins at the study’s assumed gold price, but actual economics remain sensitive to construction costs, operating inflation, metallurgical performance and realised gold prices.

How would the C$300m debt facility work?

The proposed facility carries an interest rate of adjusted term CORRA plus 4.75% during development, stepping down to CORRA plus 4.25% following project completion. Up to C$20 million of interest could be capitalised during construction.

The structure includes an anticipated C$25 million early-draw tranche. If definitive financing is completed, that capital could support early works, detailed engineering and long-lead equipment purchases before the full construction package is drawn.

Repayments would begin six months after commercial production starts, with final repayment due no later than 72 months after the initial drawdown following the early tranche. This attempts to align debt servicing with the point at which the mine should be generating commercial cash flow rather than requiring substantial principal repayment during construction.

What does Macquarie get besides interest?

The financing includes a potentially valuable gold offtake right. Macquarie would be entitled to purchase the first 50,000 ounces of gold produced each year, up to a cumulative maximum of 300,000 ounces, at a published reference price less US$50 per ounce.

Half of that offtake right would vest alongside the engagement letter and equity investment, while the remainder would vest when the project-finance facility closes. The structure shows how mining finance often extends beyond a simple interest rate, with lenders obtaining commercial rights linked directly to future production.

For Mayfair Gold shareholders, the relevant question is whether conceding part of future offtake economics is justified by reducing financing risk and potentially limiting the need for a much larger equity issue.

Why has Mayfair Gold’s share-price reaction been relatively restrained?

Mayfair Gold closed October 1 at approximately C$3.86, up about 1.1% for the session after trading as high as C$4.13. That relatively modest gain suggests the market recognised the importance of the financing framework while also distinguishing the binding C$10 million equity subscription from the non-binding C$300 million debt term sheet.

That distinction matters. Macquarie still needs to complete due diligence, including independent engineering review, and definitive documentation must be negotiated before the project debt becomes available. The facility materially improves the funding pathway without making construction financing unconditional.

Mayfair Gold’s shares also remained below levels above C$4.50 reached earlier in September, showing that the market continues to price permitting, financing, execution and gold-price uncertainty into the developer’s valuation.

What happens next at Fenn-Gib?

Mayfair Gold is targeting construction in 2028 and initial production in 2030 under its current development schedule. Before that can happen, permitting, engineering and financing need to converge into a fully executable project plan.

Macquarie’s involvement makes financing considerably more tangible, but it does not eliminate the remaining roughly C$150 million of headline initial capital not covered by the proposed C$300 million facility. Contingency funding, corporate cash, additional equity or other financing sources may still be required.

The financing framework nevertheless shifts Fenn-Gib meaningfully along the development curve. The project now has a global mining lender prepared to invest equity and work toward underwriting a debt package capable of funding most of construction.
