• Hole FG23-359 reports 27.60 g/t Au over 2.1m, hole FG23-361 intersected 16.47 g/t Au over 2.3m and hole FG23-351 reported 2.19 g/t Au over 16.8m, including 3.28 g/t Au over 7.0 and 3.21 g/t Au over 2.0m
• Mineralization outside current Fenn-Gib pit-constrained 3.38M ounce deposit
• Footwall Zone structure over 500m strike length, open in all directions
• Steep dipping mineralization from surface to below 600m
• Multiple parallel mineralized structures intersected
• Two drill rigs active at Footwall Zone

Mayfair Gold Corp. (TSX-V: MFG; OTCQB: MFGCF) is pleased to announce further results from the higher-grade Footwall Zone located approximately 100 meters to the northwest of the Fenn-Gib gold deposit. Mayfair’s 100% controlled Fenn-Gib Project, located in the Timmins region of Northeast Ontario, hosts a NI 43-101 open-pit constrained Indicated mineral resource estimate of 3.38 million ounces gold at a grade of 0.93 grams per tonne Au and an Inferred mineral resource of 0.16Moz Au at 0.85 g/t Au (see the “About Mayfair” section below). The near-surface Fenn-Gib gold mineralization is broadly disseminated striking east-west on the Pipestone Fault over more than 1.5 kilometers (km), and is over 500m wide at the west end.

Mayfair Gold President and CEO Patrick Evans commented: “The 3.38Moz Fenn-Gib deposit is a high-quality ‘anchor’ asset with very favorable geology capable of delivering industry-leading gold recoveries with standard flowsheet options. Resource drilling on the Footwall Zone discovery immediately adjacent to the Fenn-Gib deposit continues to identify wide zones of high-grade gold mineralization. Drilling has so far extended the strike of the outcropping Footwall Zone to more than 500m, remaining open to both the northeast and southwest, and confirmed continuity to a depth of more than 600m.”

Mr. Evans added: “Drilling resumes this week with one of the three drill rigs positioned approximately 1 km to the southwest of currently defined Footwall Zone mineralization, where past drilling at the G101 target intersected 4.47 g/t Au over 13.2m in hole C4-3 and 4.42 g/t Au over 3.35m in hole C4-5. Step-out drilling will test the potential continuity of mineralization between the Footwall Zone and G101.”

The Footwall Zone target consists of multiple mineralized zones hosted primarily in the footwall mafic volcanic assemblage, located immediately northwest of the Fenn-Gib gold deposit. The Footwall Zone strikes in a northeasterly direction and with a steep northerly dip. Mineralization consists of bleached, buff-altered (silica-albite-carbonate alteration), pillowed mafic volcanic with pyrite ranging from 2% to over 20%.

Metallurgical tests conducted on a Footwall Zone underground sample showed excellent metallurgy. Whole-ore cyanidation confirmed high gold recovery of 94.2% at a P₈₀ 59um grind size and 48-hour leach time (News release March 28, 2022).

The latest reported drill results are summarized in Table 1 below and Table 2 lists the drill hole details.

Additional drill results from the infill, expansion and step-out drill program will be announced as they are received.

QA/QC Controls

Mayfair Gold (Mayfair) employs a QA/QC program consistent with NI 43-101 and industry best practices. Surface drilling was conducted by Major/Norex Drilling of Timmins, Ontario and was supervised by the Mayfair exploration team. Mayfair’s drill program includes descriptive logging and sampling of the drill core for analysis at Mayfair’s secure facility located in Matheson, Ontario. Sampled drill core intervals were sawn in half with a diamond blade saw. Half of the sampled core was left in the core box and the remaining half was bagged and sealed. Mayfair utilizes accredited laboratories that include, Activation Laboratories Ltd. (Actlabs) and AGAT Laboratories Ltd. (AGAT) both located in Timmins, Ontario, and Swastika Laboratories Ltd located in Swastika, Ontario. Mayfair personnel transport the samples directly and deliver to Actlabs, and samples are collected by both AGAT and Swastika personnel directly from Mayfair’s secure core logging facility in Matheson, Ontario. Gold was analyzed by 30-gram fire assay with AA-finish. Certified reference material (CRM) standards and coarse blank material are inserted every twenty samples. Mayfair completes routine third-party check assays. Drill intercepts cited do not necessarily represent true widths, unless otherwise noted.

About Mayfair Gold

Mayfair Gold is a Canadian mineral exploration company focused on advancing the 100% controlled Fenn-Gib gold project in the Timmins region of Northern Ontario. The Fenn-Gib gold deposit is Mayfair’s flagship asset and currently hosts an updated NI 43-101 resource estimate with an effective date of April 6. 2023 of a total Indicated Resource of 113.69M tonnes containing 3.38M ounces at a grade of 0.93 g/t Au and an Inferred Resource of 5.72M tonnes containing 0.16M ounces at a grade of 0.85 g/t Au at a 0.40 g/t Au cut-off grade (Source: Tim Maunula, P. Geo., of T. Maunula & Associates Consulting Inc., who is deemed a qualified person as defined by NI 43-101). The Fenn-Gib deposit has a strike length of over 1.5km with widths ranging over 500m. The gold mineralized zones remain open at depth and along strike to the east and west. Recently completed metallurgical tests confirm that the Fen-Gib deposit can deliver robust gold recoveries of up to 94%.
