Mayfair Gold Increases Fenn-Gib Open Pit Indicated Resource by 47% to 3.06M Ounces and Inferred Resource by 315% to 0.31M Ounces

 

 

 

 

 

  • Interim resource update includes assay results up to July 31, 2022, for approx. 67,000m drilled, or 61% of current drill program
  • Infill and expansion drilling ongoing: approx. 96,000m completed to date
  • 110,000m drill program on schedule for completion in January 2023
  • Drilling shows continued expansion of the gold mineralization
  • Further resource update scheduled for Q2 2023
  • Incremental gold ounces added for average drilling cost of approx. C$6.00 per ounce

 

Mayfair Gold Corp. (TSX-V: MFG; OTCQX: MFGCF) is pleased to announce an updated mineral resource estimate at the Company’s 100% controlled Fenn-Gib Gold Project, located in the Timmins region of Northeast Ontario. Based on assay results from 61 percent of the Company’s current 110,000-meter (m) infill and expansion drill program, the Fenn-Gib deposit now hosts a NI 43-101 pit constrained Indicated mineral resource estimate of 3.06 million (M) ounces (oz) gold (Au) and an Inferred mineral resource of 0.31M oz Au. The near-surface Fenn-Gib gold mineralization is broadly disseminated striking east-west on the Pipestone Fault over more than 1.25 kilometers (km) and is up to 300m wide at the west end.

 

Mayfair Gold President and CEO Patrick Evans commented: “With the expansion of the Fenn-Gib gold zones, the mineral resources have shown significant improvement over the previous estimates. Within 18 months of acquiring Fenn-Gib, Mayfair has increased the Indicated resource size by 47 percent. The Fenn-Gib mineralization remains open for expansion in most directions, and we are excited about the near-term potential to further increase the resources with the ongoing drill program supported by three drill rigs.”

 

Mr. Evans added: “A large portion of the incremental tonnes reported today come from the Expansion Zone in the center of the Fenn-Gib deposit and to the east of the higher-grade Main Zone. Previously poorly defined, the Expansion Zone has been the focus of Mayfair’s drill program, supported by two of the three drill rigs, and has added significant tonnage to the Fenn-Gib mineral resources.”

 

The 30,000m Phase 3 infill and expansion drill program is ongoing with gold mineralization continuing to be intersected in all holes reported to date. Based on the continuing success, Mayfair expects to declare a further resource update in Q2 2023 on completion of the 110,000m drill program. The potential exists for a further significant increase in the Fenn-Gib resource.

 

Highlights of the Updated Fenn-Gib Mineral Resource Estimate:

  • Pit constrained Indicated resource: 47% increase in Au to 3,061,991 oz from 2,077,661 oz
  • Pit constrained Inferred resource: 315% increase in Au to 311,356 oz from 74,967 oz
  • Maiden underground resource: Inferred underground Au resource of 103,586 oz

Notes:

  1. Effective date of this updated mineral resource estimate is October 15, 2022. The effective date for the drill-hole database used to produce this updated mineral resource estimate is July 31, 2022.
  2. All mineral resources have been estimated in accordance with Canadian Institute of Mining and Metallurgy and Petroleum definitions, as required under NI 43-101. Mineral Resource Statement prepared by Garth Kirkham, P. Geo (Kirkham Geosystems Ltd.) in accordance with NI 43-101.
  3. Mineral Resources reported demonstrate reasonable prospect of eventual economic extraction, as required under NI 43-101. Mineral Resources are not Mineral Reserves and do not have demonstrated economic viability. The Mineral Resources may be materially affected by environmental, permitting, legal, marketing and other relevant issues.
  4. Mineral Resources are reported at a cut-off grade of 0.35 g/t Au for an open-pit mining scenario. Cut-off grades are based on a price of US$1,750/oz gold, and a number of operating cost and recovery assumptions, including a reasonable contingency factor. Metallurgical recoveries of 94% were used. Densities were assigned based on physical measurements.
  5. Ounce (troy) = metric tonnes x grade / 31.10348. All numbers have been rounded to reflect the relative accuracy of the estimate.
  6. The quantity and grade of reported Inferred Resources are uncertain in nature and there has not been sufficient work to define these Inferred Resources as Indicated or Measured Resources. It is reasonably expected that most of the Inferred Mineral Resources could be upgraded to Indicated Mineral Resources with continued exploration.
  7. Tonnages and ounces in the tables are rounded to the nearest thousand and hundred, respectively. Numbers may not total due to rounding.

 

Based on Mayfair’s drilling costs, the incremental gold ounces reported have been added at an average cost of approx. C$6.00 per ounce. Despite a modest increase in drilling costs to account for increased fuel prices, Mayfair expects to continue adding to the Fenn-Gib resource at industry-leading costs.

February 5, 2021 Fenn-Gib Mineral Resource Estimate

 

A pit-constrained NI 43-101 resource estimate was completed entitled “NI 43-101 Technical Report Fenn-Gib Project, Ontario, Canada” dated February 5, 2021, by JDS Energy and Mining Inc. and prepared by Garth Kirkham, P. Geo., an Independent Qualified Person as defined by NI 43-101, from Kirkham Geosystems Ltd.

 

QA/QC Controls

 

Mayfair Gold 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.
