Company Announcements

VANCOUVER, BC , April 2, 2026 /CNW/ - Mayfair Gold Corp.("Mayfair", "Mayfair Gold", or the "Company") (TSXV: MFG) (NSYE American: MINE) is pleased to announce that it has entered into a definitive agreement (the "Acquisition Agreement") with Plato Gold Corp. ("Plato") to acquire Plato's interests in the Guibord, Marriott and Holloway properties (the "Properties") for C$2.5 million in cash. The properties are in close proximity to Mayfair's Fenn-Gib Gold project ("Fenn-Gib" or the "Project") east of Timmins, Ontario. The transaction provides Mayfair with three exploration properties that overlay the regionally important Porcupine-Destor Fault Zone ("PDFZ") and provides critical land adjacent to the Project to the southwest to support potential onsite infrastructure.

Mayfair has a clearly defined path to permit and advance a new mine into production at Fenn-Gib. Mayfair also sees substantial potential to enhance the project economics and production profile of Fenn-Gib through near site exploration. Exploration leverage gives Mayfair an additional lever to create value as the company derisks and advances Fenn-Gib.

Nick Campbell, CEO of Mayfair Gold commented, "We are excited to enter into this agreement with Plato to expand our land holdings near the Fenn-Gib Gold Project by more than 65%. All three properties are closely associated with the Porcupine-Destor Fault Zone, a significant regional structure within the Abitibi Greenstone belt that has produced more than 180 million ounces of gold historically. This transaction, as well as targets within our current land holdings provide Mayfair with new exploration leverage adjacent to and within hauling distance of the proposed Fenn-Gib mine. Furthermore, the Guibord property facilitates critical access for potential onsite infrastructure supporting our permitting process "

Strategic highlights

• The Guibord property (50%)
  • Hosts Plato's Silver Fox Project
  • <5km southeast of McEwen Mining's Grey Fox project and Black Fox mine
  • Contiguous to Fenn-Gib concessions, 5km southwest of the deposit
  • 16 contiguous mining claims, two mining leases, covering 275 hectares
  • Highway 572 access to site (western boundary)
  • Provides key land access to support Fenn-Gib permitting

The Guibord property is along strike from McEwen Mining's Grey Fox project and Black Fox Mine along the PDFZ. The historic drilling in 1964 was focused on the contact between the Porcupine-Destor metasediments and the ultramafics of the Stoughton-Roquemaure Assemblage, targeting a series of potentially gold bearing alteration zones. Historic drilling in the 1960's tested several areas which returned narrow intervals of high-grade gold mineralization (13.7 g/t gold over 1.22 metres and 47.01 g/t gold over 0.91 metres) and several broad zones of lower-grade gold mineralization (0.59 g/t gold over 30.5 metres and 0.66 g/t gold over 23 metres.

• The Marriott Property (100%)
  • Located 15km east of the shuttered Holt and Holloway Gold Mines
  • Located ~55km east of the Fenn-Gib Gold Project
  • 142 contiguous mining claims, covering 2,728 hectares
  • Highway 101 access to site
  • Early-stage exploration project within trucking distance of Fenn Gib

The Marriott property is underlain by a series of basalt flows, breccias and hyaloclastites belonging to the Kinojevis Assemblage with occasional interflow graphitic sediments occurring between the basalt flows. Gold mineralization at the Holloway mine was closely associated with a geological contact and the PDFZ located between the Kinojevis Assemblage and the Stoughton-Roquemaure Assemblage and associated structures. An 11-hole 2,858-metre diamond drill program was completed by Plato in 2005. Three of the holes intercepted gold mineralization of more than 1.0 g/t gold.

• The Holloway Property (100%)
  • Located 3km east-northeast and east of the Holt and Holloway Mines, respectively
  • Located ~43km east of the Fenn-Gib Gold Project
  • 10 contiguous mining claims covered by a mining lease, covering 156 hectares
  • Highway 101 access to site
  • Early-stage exploration project within trucking distance of Fenn Gib

The Holloway property is primarily underlain by Kinojevis Assemblage iron and magnesium rich tholeiitic basalts with the northern margin of the property underlain by Timiskaming-style metasediments bounded by the PDFZ. Historical drilling in 1987 intersected narrow zones of high-grade mineralization reported at 52-64 g/t gold over 0.3 - 0.8 metre intervals. The potential for extensions of the Holloway mine mineralization may exist at a depth of 1,000 – 1,200 metres within the property.

Terms of the Purchase Agreement for the Marriott, Holloway and Guibord properties

Mayfair has entered into an asset purchase agreement with Plato for its 100% interest in the Marriott properties, its 100% interest in the Holloway properties and its 50% interest in the Guibord properties for total consideration of C$2.5 million in cash.

The transactions contemplated by the Acquisition Agreement are subject to customary conditions precedent, including ministerial consent with respect to the transfer of certain mining leases.

On closing, the cash consideration will be paid into escrow and held by an escrow agent. 50% of the funds will be released from escrow to Plato upon the transfer of the Marriott Property, 25% will be released from escrow on the transfer of the Holloway Property and the final 25% will be released from escrow on the transfer of the Guibord Property.
