Mayfair Gold Corp. announced the successful completion of the geotechnical and hydrogeology studies in support of pre-feasibility-level open-pit design for the Fenn-Gib Project. 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 (M) ounces (oz) gold (Au) at a grade of 0.93 grams per tonne (g/t) Au, and an Inferred mineral resource of 0.16Moz Au at 0.85 g/t Au.

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 500 meters (m) wide at the west end. Mayfair Gold contracted InnovExplo Inc. to manage the geotechnical and hydrogeology campaign. Field data was collected from geomechanical drilling, televiewer, and hydrogeological analyses to support laboratory testing.

Seven geomechanical holes were drilled (3,228m) and 11 holes were surveyed using televiewer (5,306m). A total of 395 laboratory tests were performed to characterize the rock mass, along with various point load tests and other tests. The geological and geomechanical surveys described eight distinct geomechanical units?including the deformation zone, mafics, and sedimentary units, which form most of the modeled pit walls.

Laboratory tests (including uniaxial compressive tests, Brazilian tests, and triaxial tests) were carried out on all geomechanical units, except for the diabase and the ultramafic volcanic units. All geomechanical units demonstrated good rock mass quality based on the RMR89, Q-system, and GSI classifications, except for the diabase, which has an average Q-value of weak. The mafics, main zone, and sedimentary units yielded the best properties from the laboratory tests, with uniaxial compressive strength estimated over 100 MPa.

The deformation, footwall, and pyroxenite zones showed lower property values.
