08:17 AM EDT, 05/28/2025 (MT Newswires) -- Mayfair Gold ( MFGCF ) reported overnight Tuesday "excellent" gold recovery rates from the metallurgical test program under a pre-feasibility study (PFS) for the Fenn-Gib gold project in Ontario.

The company said the test work evaluated the performance of 50 composite samples selected to represent the variability of the overall deposit lithologies, across a head grade range of 0.20 to 9.92 grams per tonne (g/t) gold.

Mayfair said results achieved between 94-97% recovery of gold to the concentrate. After rougher concentrate regrind and cyanidation, the tests indicate an overall metallurgical gold recovery of approximately 82.5% at a feed grade of 0.8 g/t and 88.4% at 1.5 g/t, the company said.

"The results are instrumental in determining the predicted metallurgical recovery, and importantly, validated a largely conventional process flow sheet including crush and grind, rougher flotation, concentrate regrind and cyanidation for the project PFS," said Nick Campbell, president and CEO of Mayfair.

The PFS is scheduled to be completed by year-end 2025, Mayfair said.
