MFG Mayfair Gold Corp

Mayfair Gold Corp. (“Mayfair” or the “Company”) (TSX-V: MFG; OTC: MFGCF) is pleased to announce positive results from the Company’s 2022 preliminary metallurgical gold recovery test (“MET”) program performed on seven separate composited core‐based bulk samples from the Fenn-Gib deposit. The MET campaign is managed by Ausenco Engineering Canada Inc. (“Ausenco”) as part of the planned preliminary economic assessment (“PEA”) expected to be completed by Q4 2022. The 100% controlled Fenn-Gib deposit, located in the Timmins region of Northeast Ontario, hosts a NI 43-101 pit-constrained Indicated Resource of 2.08M ounces (see the “About Mayfair” section below) with disseminated gold mineralization striking east-west on the Pipestone Fault over 1.25 kilometers (km) and is up to 300 meters (m) wide at the west end.

Mayfair Gold President and CEO Patrick Evans commented: “Our maiden MET campaign confirms that the Fenn-Gib deposit can deliver robust recoveries for both direct whole ore cyanidation and flotation. While varying in sulfide content, values associated with Fenn-Gib ore are not considered refractory. We are particularly excited about the benefits that flotation may potentially offer for the project economics. The MET results indicate that Fenn-Gib can deliver a clean, high-grade sulfide-and-iron-rich gold concentrate that would be very suitable for milling in conventional leaching or autoclave operations. Importantly, flotation has the potential to significantly reduce capital and operating costs, expedite permitting and materially reduce final closure and reclamation costs.”

The MET program was conducted to assess the potential gold recoveries and to support the selection of the most appropriate process flowsheet for the Fenn-Gib deposit. Ausenco selected seven different drill hole sample locations to be spatially distributed within the conceptual open pit shell, as well as to align with the estimated average gold grade. The program was performed on the seven composited diamond drill core samples collected from NQ size half core taken from the 2021 drill program. Five of the samples are from the central, south, and east areas of the Fenn-Gib deposit, and the sixth is from the Footwall mineralization that lies within the conceptual open pit. The seventh composited sample is from the Footwall Zone outside of the conceptual open pit, which has potential for inclusion in future conceptual mine plans.

Three primary processing options for gold recovery were undertaken by SGS Minerals Services, including whole ore leach, flotation and flotation regrind leach. The tables below summarize the MET test results.

Table 1 below summarizes the whole ore cyanidation leach test results for the Fenn-Gib Main/Deformation Zone.

Table 1 - Main/Deformation Zone whole ore cyanidation results

Sample	Head Grade (Au g/t)	Grind P80 (μm)	Leach Time (h)	Recovery (Au %)
Central Pit Upper	1.00	59	48	79.0
Central Pit Mid	1.27	62	48	83.4
Central Pit Lower	2.93	55	48	91.4
South Pit	0.98	63	48	88.8
East Pit	0.75	59	48	78.8

The overall average recovery is 84.3%, with the best results in the central and south portions of the conceptual open pit.

Table 2 below summarizes the flotation test results for the Fenn-Gib Main/Deformation Zone.

Table 2 - Main/Deformation Zone flotation results

Sample	Head Grade		Rougher Concentrate			Cleaner Concentrate
			Recovery (% of circuit feed)		Grade	Recovery (% of circuit feed)		Grade
	Au (g/t)	S (%)	Mass	Au	Au (g/t)	Mass	Au	Au (g/t)
Central Pit Upper	1.00	3.02	15.6	96.0	6.46	6.3	93.7	15.6
Central Pit Mid	1.27	2.22	12..2	95.3	8.80	3.8	93.0	27.4
Central Pit Lower	2.93	0.94	14.7	95.8	9.32	2.0	94.3	66.7
South Pit	0.98	2.62	24.4	95.1	3.59	3.8	93.0	13.3
East Pit	0.75	1.84	20.8	97.9	3.58	4.7	95.1	15.4

Samples were ground to 80% passing approximately 70 µm prior to flotation, and flotation concentrates were reground to approximately 80% passing approximately 15 µm. Concentrate grades and recoveries were achieved with three cleaning stages. Concentrates contain between 80% and 95% pyrite. Final concentrate gold grades are sufficiently high to be sold for potential third-party processing in conjunction with the high pyrite contents.

Table 3 below summarizes the flotation regrind leach test results for the Fenn-Gib Main/Deformation Zone.

Table 3 - Main/Deformation Zone flotation regrind leach test results

Sample	Head Grade (Au g/t)	Regrind P80 (μm)	Leach Time (h)	Recovery (Au %)
				RougherConcentrate	Leach	Overall
Central Pit Upper	1.00	17	48	96.0	87.9	84.4
Central Pit Mid	1.27	14	48	95.3	89.9	85.7
Central Pit Lower	2.93	12	48	95.8	96.6	92.5
South Pit	0.98	18	48	95.1	87.9	83.6
East Pit	0.75	15	48	97.9	88.3	86.4

Regrinding and leaching of flotation concentrates provides slightly higher recoveries than whole ore leaching subject to economic analysis.

Table 4 below summarises whole ore cyanidation results for the Fenn-Gib Footwall Zone.

Table 4 - Footwall Zone whole ore cyanidation results

Sample	Head Grade (Au g/t)	Grind P80 (μm)	Leach Time (h)	Recovery (Au %)
Footwall	0.55	59	48	59.8
Footwall U/G	3.38	59	48	94.2

The low head grade of the Footwall sample is a contributing factor in the low recovery.   The Footwall U/G sample shows good metallurgy with high recoveries at a typical underground gold grade.

Table 5 below summarises the flotation test results for the Fenn-Gib Footwall Zone.

Table 5 - Footwall Zone flotation results

Sample	Head Grade		Rougher Concentrate			Cleaner Concentrate
			Recovery (% of circuit feed)		Grade	Recovery (% of circuit feed)		Grade
	Au (g/t)	S (%)	Mass	Au	Au (g/t)	Mass	Au	Au (g/t)
Footwall	0.55	4.64	22.0	94.3	2.33	9.7	89.3	5.01
Footwall U/G	3.38	2.81	17.94	93.5	17.9	5.0	91.5	58.4

Table 6 below summarizes the flotation regrind leach test results for the Fenn-Gib Footwall Zone.

Table 6 - Footwall Zone flotation regrind results

Sample	Head Grade(Au g/t)	Regrind P80(μm)	Leach Time(h)	Recovery (Au %)
				RougherConcentrate	Leach	Overall
Footwall	0.55	23	48	94.3	63.6	60.0
Footwall U/G	3.38	15	48	93.5	97.5	91.2

The Footwall sample recovery is comparable to the whole ore leach recovery, while the Footwall U/G sample is lower.

Based on the above results, Ausenco will undertake a trade-off study between the three selected process flowsheets in preparation for the PEA that will commence on completion of the 80,000m infill and expansion drill program currently underway. Approx. 66,000m of drilling has been completed to date. The drill program is on target for completion by mid-2022 and is expected to support a resource update by Q3 2022.

QA/QC

For this metallurgical study, NQ sized drill core was logged, sawn in half with the half core sampled and bagged and sent to Actlabs laboratory in Timmins for gold assays on individual samples (see Mayfair QA/QC below). For the metallurgical test work at SGS Canada Inc. (SGS) laboratories, the Actlabs gold assay results were used by Mayfair and Ausenco (managing the SGS test work) to produce seven sample composites from the remaining sawn half core to best represent a range of locations within the Fenn-Gib deposit. The remaining half core was sampled by Mayfair staff, bagged and sent to SGS. SGS conducted the metallurgical test work at the SGS Lakefield, Ontario laboratory. SGS conforms to the requirements of ISO/IEC 17025 and is accredited by the Standards Council of Canada for the specific tests undertaken.

Mayfair employs a QA/QC program consistent with NI 43-101 and industry best practices. Surface drilling is conducted by Major/Norex Drilling of Timmins, Ontario and is supervised by Mayfair’s 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 are sawn in half with diamond blade saws. Half of the sampled core is left in the core box and the remaining half is bagged and sealed. Mayfair utilizes accredited laboratories and the samples are transported by Mayfair personnel to the Actlabs laboratory in Timmins, Ontario. Gold is analyzed by 30-gram fire assay with AA-finish. Certified reference material (CRM) standards and coarse blank material are inserted every 20 samples. Drill intercepts cited do not necessarily represent true widths, unless otherwise noted.
