VANCOUVER, British Columbia, Sept. 11, 2023 (GLOBE NEWSWIRE) -- Mayfair Gold Corp. ("Mayfair" or the "Company") (TSXV:MFG, OTCQB:MFGCF) is pleased to announce further drill results from the higher-grade Footwall Zone located approximately 100 meters (m) to the north 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 (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 (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 Fenn-Gib pit-constrained deposit is a high-quality ‘cornerstone' asset with highly favorable geology capable of delivering industry-leading gold recoveries with standard flowsheet options. Beyond that, ongoing drilling at the Footwall Zone and Contact Zone discoveries immediately adjacent to the Fenn-Gib deposit continues to identify wide zones of higher-grade gold mineralization. Step-out drilling supported by two drill rigs has so far extended the strike of the outcropping Footwall Zone to more than 500m, remaining open both to the northeast and southwest, and confirmed continuity to a depth of more than 600m. Mayfair expects to report a maiden underground Footwall Zone resource in early 2024."

1. FG23-345 intersected 1.44 g/t Au over 49.5m, including 9.20 g/t Au over 2.5m and 2.92 g/t Au over 3.0m;
   
   
2. FG23-304 intersected 1.46 g/t Au over 25.9m, including 14.32 g/t Au over 1.0m and 3.0 g/t Au over 3.5m and 5.88 g/t Au over 1.9m;
   
   
3. FG23-314 intersected 2.19 g/t Au over 17.1m, including 13.67 g/t Au over 2.0m; and
   
   
4. FG23-326 intersected 3.67 g/t Au over 8.0m, including 6.47 g/t Au over 4.2m including 19.89 g/t Au over 0.9m.
   

The latest drill results continue to intersect significant gold mineralization building on Mayfair's previously reported Footwall Zone drill results that included: hole FG21-139 intersected 1.94 g/t Au over 38.0m, including 4.06 g/t Au over 15.0m (news release June 01, 2021); FG21-166 intersected 1.42 g/t Au over 66.0m, including 3.4 g/t Au over 19.2m, including 6.20 g/t Au over 9.2m. A lower zone in hole FG21-166 returned 1.02 g/t Au over 34.0m, including 11.49 g/t Au over 1.0m; FG21-170 intersected 37.51 g/t Au over 2.6m and 59.05 g/t over 1.0m; hole FG21-186 intersected 2.31 g/t Au over 30.0m, including 6.58 g/t Au over 7.0m (news release October 25, 2021). FG21-188 intersected 25.93 g/t Au over 1.5m, 1.37 g/t Au over 25.5m including 5.4 g/t Au over 5.0m; FG21-203 intersected 2.70 g/t Au over 15.0m; including 4.04 g/t Au over 9.0m, including 7.18 g/t Au over 4.0m; FG21-215 intersected 2.88 g/t Au over 49.0m, including 6.53 g/t Au over 17.5m and FG22-218 intersected 0.71 g/t Au over 92.0m, including 2.15 g/t Au over 10.0m. A lower zone returned 2.40 g/t Au over 47.4m, including 3.83 g/t Au over 4.7m and 5.26 g/t Au over 6.6m and 6.78 g/t Au over 7.0m (news release June 15, 2022). FG23-300 intersected 2.05 g/t Au over 16.2m, including 3.72 g/t Au over 6.2m (news release February 27, 2023), and hole FG23-328 returned 15.65 g/t Au over 1.5m and 7.94 g/t Au over 7.0m and hole FG23-344A intersected 4.72 g/t Au over 30.0m, including 6.59 g/t Au over 19.6m (June 21, 2023 news release).

The Footwall Zone target consists of multiple mineralized zones hosted primarily in the footwall mafic volcanic assemblage, located immediately north of the Fenn-Gib deposit striking in a north easterly 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 testwork on a Footwall Zone underground composite sample indicated favorable performance, with whole ore cyanidation yielding 94.2% Au extraction at a P₈₀ 60 µm grind and 48-hour leach time from a head grade of 4.15 g/t Au with 2.5% S^2- (news release March 28, 2022). Alternative processing schemes considered flotation at 80% passing 100 µm to a rougher concentrate at 20% mass pull, followed by fine grinding to 80% passing 10 µm and cyanidation of the concentrate which yielded similar 94% overall Au recovery for the Footwall underground composite. The hybrid approach involving flotation-regrinding-cyanidation demonstrated consistent overall Au recovery over the expected variability in deposit lithology, gold and sulfide content.
