6 terms

indicated mineral resource technical

"indicated mineral resource of 4.3 million ounces"

A quantified portion of a mineral deposit where geological evidence and sampling give a reasonable level of confidence in the quantity, grade and continuity of the minerals — think of it as a well-marked stretch on a treasure map rather than a vague hunch. It matters to investors because it provides a credible estimate that can be used for preliminary economic studies and valuation, reducing uncertainty compared with less-certain resource categories.

probable mineral reserve technical

"probable mineral reserve of 1 million ounces"

A probable mineral reserve is the portion of a mineral deposit that geologists and engineers judge likely to be economically mineable based on available data and reasonable assumptions about extraction, costs and market conditions; it carries a moderate level of confidence, higher than a resource estimate but lower than a proven reserve. Investors care because it represents the amount of commodity a company can reasonably expect to convert into saleable product—like a cautiously optimistic shopping list that helps estimate future production, revenue and project risk.

Pre-Feasibility Study technical

"the expected strategy outlined in the 2026 Pre-Feasibility Study"

A pre-feasibility study is an initial assessment that evaluates whether a proposed project or investment idea is worth exploring further. It involves examining basic factors like costs, potential benefits, and possible challenges, similar to conducting a preliminary check before deciding to invest more time and resources. This helps investors determine if pursuing the project further is practical and likely to be successful.

free cash flow financial

"cumulative free cash flow of US$896 million"

Free cash flow is the amount of money a company has left over after paying all its expenses and investing in its business, like buying equipment or updating facilities. It shows how much cash is available to reward shareholders, pay down debt, or save for future growth. This helps investors understand if a company is financially healthy and able to grow.

hold period regulatory

"4-month and one day “hold period”"

A hold period is a specific span of time during which an investor is required or expected to keep a security or asset and cannot freely sell it or realize its value. It matters because it limits liquidity and can affect tax treatment, risk exposure and timing of gains or losses—like a cooling-off or fixed-term commitment that prevents you from quickly cashing out even if market conditions change.

non-GAAP financial measures financial

"prospective non-GAAP financial measures"

Non-GAAP financial measures are numbers companies use to show their financial performance that exclude certain expenses or income. They help investors see how the company might perform without one-time costs or other unusual items, giving a different perspective from official reports. However, since they can be adjusted, they don’t always tell the full story and should be looked at alongside standard financial figures.

About Mayfair Gold

Mayfair Gold is a Canadian development-stage gold company focused on advancing the 100%-owned Fenn-Gib Project in the Timmins region of Northern Ontario. Fenn-Gib hosts a 4.3-million-ounce indicated mineral resource of gold (181.3Mt at an average grade of 0.74 g/t) and the expected strategy outlined in the 2026 Pre-Feasibility Study (the "PFS")¹ is to develop the Project under the provincial permitting process, targeting the higher-grade 1-million-ounce probable mineral reserve (25.1Mt at an average grade of 1.29g/t) sitting near-surface, highlighting the optionality and scalability provided by the deposit.  The PFS also outlines the potential to develop Fenn-Gib into a new Canadian gold producer, with initial development capital of C$450 million, a base-case payback period of 2.7 years, and cumulative free cash flow² of US$896 million over the first six years of production based on a US$3,100/oz gold price. The Company is advancing permitting activities, detailed engineering, and stakeholder engagement with the goal of starting construction in 2028 with initial production in 2030. The Company also remains focused on exploration around the broader land package with the goal of enhancing mineral resource scale and growth opportunities.

² Free cash flow does not have a standardized meaning and may not be comparable to similar measures presented by other issuers, referred to as non-GAAP financial measures. As the Corporation is not in production, the Corporation does not have historical non-GAAP financial measures nor historical comparable measures under IFRS, and therefore the foregoing prospective non-GAAP financial measures may not be reconciled to the nearest comparable measures under IFRS.
