Mayfair Gold Corp. (TSX-V: MFG) (OTCQB: MFGCF) is pleased to announce the latest set of drill results from the Fenn-Gib resource expansion and infill drill program. Mayfair’s 100% controlled Fenn-Gib Project, located in the Timmins region of Northeast Ontario, hosts a NI 43-101 open-pit-constrained Indicated Resource of 3.06 million (M) ounces and an Inferred Resource of 0.31M ounces (see the “About Mayfair” section below), with disseminated gold mineralization striking east-west on the Pipestone Fault over more than 1.25 kilometers (km) and up to 300 meters (m) wide at the west end.

Mayfair Gold President and CEO Patrick Evans commented: “Exceptionally wide intercepts of gold mineralization continue to be reported from ongoing infill and expansion drilling at the Fenn-Gib deposit. Holes FG22-294A and 298A, drilled on the same section, successfully extended significant gold mineralization well into the north side of the current conceptual open pit. Additional results from Fenn-Gib infill drilling are pending.”

Highlight drill results include:

1. FG22-298A intersected 0.71 grams per tonne (g/t) Gold (Au) over 371.0m, including 1.00 g/t Au over 71.0m and 0.91 g/t Au over 137.8m;
2. FG22-294A intersected 11.43 g/t Au over 6.0m including 64.15 g/t Au over 1.0m, 0.90 g/t Au over 121.7m including 1.12 g/t Au over 45.5m and 1.56 g/t Au over 28.6m, 0.53 g/t Au over 42.4 (this last interval remains open downhole with assays pending).

Mr. Evans added: “Currently, two drill rigs are defining the full extent of the higher-grade Footwall Zone mineralization located immediately to the northwest of the Fenn-Gib deposit. A third drill rig is executing the open-pit geotechnical program in support of Mayfair’s planned pre-feasibility study, which is scheduled to begin shortly and expected to be completed in H2 2023. On the Fenn-Gib North Block, approximately 102 line km of IP geophysical surveys were completed on Grid A, successfully defining five new compelling coincident IP chargeability and resistivity drill targets. The IP survey on Grid B over the Footwall Zone gold trend is expected to be completed by month end. Results from the geophysical programs will guide further drill programs.”

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 of a total open-pit constrained Indicated Resource of 118.07M tonnes containing 3.06M ounces at a grade of 0.81 g/t Au and an Inferred Resource of 13.8M tonnes containing 0.31M ounces at a grade of 0.70g/t Au. (Source: Garth Kirkham, P. Geo., of Kirkham Geosystems Ltd., who is deemed a qualified person as defined by NI 43-101, dated October 15, 2022). The Fenn-Gib deposit has a strike length of approx. 1.25km with widths ranging up to 300m. 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%.
