• Targeting near surface high-grade mineralization to support open pit mining operation
• Reverse circulation drill program planned to improve confidence in the zone targeted for early years of operations at Fenn-Gib

VANCOUVER, BC , June 9, 2025 /CNW/ - Mayfair Gold Corp.("Mayfair", "Mayfair Gold" or the "Company") (TSXV: MFG) (OTCQX: MFGCF) is pleased to provide an update on the conceptual pit designs being progressed to advance the Pre-Feasibility Study ("PFS") for the Fenn-Gib Gold Project in Ontario ("Fenn-Gib" or the "Project"). The PFS work is focused on advancing Fenn-Gib based on an open pit mining operation targeting a high-grade starter zone of mineralization.

The Company's updated mineral resource estimate for the Fenn-Gib Project was released with an effective date of September 3, 2024 and originally presented in a news release dated September 10, 2024.  At a 0.30 g/t gold cutoff, there is a total Indicated Mineral Resource estimate of 181.3 million tonnes at a grade of 0.74 g/t gold containing 4.3 million ounces of gold and an Inferred Mineral Resource estimate of 8.92 million tonnes at a grade of 0.49 g/t gold containing 0.14 million ounces of gold. The mineral resource estimate ("MRE") will be the basis for the PFS which is currently in progress and is expected to be completed by the end of 2025.

For the PFS, the Company is targeting a mine design focused on the high-grade mineralization in the upper elevations of the open pit MRE to maximize the feed grade to the proposed processing plant.  It is anticipated that the design will include a conventional drill and blast, with truck and shovel open pit mining operation supplying the plant.  By applying a strategy that emphasizes an elevated cut-off grade targeting the high-grade near surface mineralization within the MRE, the result will maximize the value of the Fenn-Gib asset in the short-term while maintaining the integrity of the overall resource. 

Figure 1 shows the possible pit outline of a design using 0.8g/t COG and targeting a high-grade pit.

Reverse Circulation Drilling Program to Commence in Summer 2025

To provide additional data and improve confidence in the near surface high-grade zone of mineralization targeted in the early years of the proposed mine plan, Mayfair plans to complete a 20,000-metre reverse circulation ("RC") drill program at Fenn-Gib. The RC drilling program is to be completed in two stages.  The first stage of the RC drill program is planned to begin in the summer of 2025, utilizing the existing onsite road network to partially test the near surface high grade zone. The second stage of the RC drill program will begin after the 2025 winter freeze-up, when ground conditions improve to allow Mayfair to more effectively complete the remaining RC drill program. This program will also advance additional diamond drilling with open pit geotechnical holes for improved clarity on pit wall designs needed for future operations.

Nick Campbell, President and CEO of Mayfair Gold, stated, "Many open pit gold deposits have better grade deeper in the deposit. We believe Fenn-Gib is unique in that some of the highest grade mineralization occurs near surface. This allows for the potential to start operations at Fenn-Gib with a smaller, targeted, mining operation, focused on the near-surface, high-grade gold mineralization.  Rather than targeting a larger scale operation, we think this approach allows Mayfair to focus operations on higher margin material at the start of operations, it mitigates construction execution risk, reduces initial capital requirements and provides a clear Ontario Provincial permitting path. With a current Canadian gold price in excess of C$4,600/oz, Mayfair is excited about the opportunity to advance Fenn-Gib into a new gold producer within the current gold cycle. The PFS is expected to be completed by the end of 2025. A nimble, smaller, targeted, high-grade operation should provide a path forward for the company to consider a production decision within the next three years.  Advancing Fenn-Gib to production and cash flow should help fund potential future growth opportunities, including the potential to permit and develop a larger operation at Fenn-Gib that optimizes the full MRE."

Mayfair Evaluating Potential to Uplist to NYSE American Exchange

The Company is pleased to report that it is reviewing the potential to uplist to the NYSE American Exchange from the current OTCQX listing in the United States.  Mayfair is reviewing the listing requirements and potential timelines to complete the uplisting process. The Company intends to provide further updates on the potential uplisting for Mayfair shares in the future.
