Mayfair Gold Corp. Delivers Robust Pre-Feasibility Study for the Fenn-Gib Gold Project

Mayfair Gold Corp. announced the results of its 2026 Pre-Feasibility Study ("PFS") for the Fenn-Gib gold project in the Timmins Gold District of Ontario, Canada. The study has been prepared in accordance with National Instrument 43-101 – Standards of Disclosure for Mineral Projects ("NI 43-101"). The NI 43-101 Technical Report for the PFS will be filed within the next 45 days and will be made available under the Company's profile on SEDAR+ and on the Company's website. Unless otherwise stated, all dollars in this news release are expressed in Canadian dollars. Highlights of the 2026 PFS for the Fenn-Gib Gold Project in Ontario include an after-tax NPV(5%) of USD 652 million and IRR of 24% at a USD 3,100/oz base case gold price and 1.35 CAD/USD exchange rate, and an after-tax NPV(5%) of USD 1.37 billion and IRR of 38% at a USD 4,450/oz spot gold price and 1.38 CAD/USD exchange rate. The study reports an average grade processed of 1.47 g/t gold over the first six years of operations for average annual gold production of 71,336 ounces at an AISC of USD 1,171/oz, and an average grade processed of 1.29 g/t gold over the 14.3-year reserve life for average annual gold production of 64,096 ounces at an AISC of USD 1,292/oz. Free cash flow in the first six years of operation is estimated at over USD 896 million at the base case gold price and $1.43 billion at the spot gold price, with initial development capital costs of USD 450 million and a short payback period of 2.7 years on the base case, dropping to 1.7 years at spot gold. The mine plan and associated economics only exploit 1.04 Moz (24%) of the total 4.3 Moz Indicated Resource, preserving optionality for future growth. Environmental Baseline studies are well advanced to allow for early 2026 commencement of the Environmental Assessment and Ontario permitting process, with a final investment decision expected within three years and commercial operation within five years. The study outlines Mayfair's strategy to reduce execution risk and prioritize high-margin material early in the mine plan, supported by a realistic and financeable initial capital outlay, enabling rapid value generation from Fenn-Gib while preserving long-term flexibility to deploy free cash flow toward regional growth opportunities or advancing secondary assets to diversify and expand production. Economic results are presented on an unlevered basis to highlight the strong standalone project returns, and Mayfair intends to prudently utilize project-level debt and other financing options to minimize overall cost of capital and maximize per-share economic returns. Initial capital expenditures are estimated at USD 450 million, including a 26% contingency on direct costs, and the PFS considers a conventional open-pit mining operation with modular processing plant designs allowing for a simplified construction schedule of less than 24 months, reducing inflationary and execution risks. The Project will proceed under the Provincial Class Environmental Assessment process and does not trigger a Comprehensive EA or federal Impact Assessment under current regulations. Social and community engagement has focused primarily on the Apitipi Anicinapek Nation due to its proximity to the Fenn-Gib site, with an active Exploration Agreement in place and continued collaborative consultation toward a Community Benefit Agreement. The Project plans to advance Ontario-led environmental approvals, Indigenous agreements, and engineering-design-procurement in parallel to enable major construction within 24–36 months and commercial operations within five years. The 2026 PFS assumes an average annual gold production of 71.3 koz over the first six years of operation and total life-of-mine production of 920 koz over 14.3 years. Base case economics are calculated on an unlevered basis using a gold price of USD 3,100 and a flat exchange rate of CAD 1.35 per USD 1, including an effective royalty rate averaging 1.7%. Free cash flow after working capital changes is expected to total USD 896 million in the first six years, increasing to USD 1.43 billion at a spot gold price of USD 4,450/oz. The mine plan reflects total gold processing of 1.04 Moz with 88.3% recovery, representing 24% of the September 3, 2024 Indicated Mineral Resource estimate of 4.3 Moz. Sensitivity analysis shows that every USD 100 change in the gold price assumption results in an approximate USD 50 million change in NPV. Initial capital cost is estimated at USD 450 million including USD 66 million of contingency, with a main construction period of 18 to 24 months. Sustaining capital includes mining fleet additions and replacement, highway relocation, and future TSF dam raises, with no provision for potential plant expansion capital. Life-of-mine unit operating costs are estimated at USD 59.43 per tonne of ore processed, with average life-of-mine cash costs and AISC of USD 1,203 and USD 1,292 respectively. The PFS outlines a production profile based on a high-grade open pit with a projected operating mine life of 14.3 years, averaging 1.29 g/t Au and metallurgical recovery of 88.3%, with first six-year average annual production of 71,336 oz at a feed grade of 1.47 g/t and peak output of over 82,000 oz in year two, while mined Reserves represent only 24% of the overall 4.3 Moz Indicated Mineral Resource.
