Its plans come as miners are increasingly aiming to reduce emissions, although recent analysis by Bloomberg Intelligence indicated the majority had failed to set carbon reduction goals that aligned with climate goals under the Paris agreement.

Mayfair said it would partner with a leading sustainability advisor to record carbon emissions at Fenn-Gib and the impact of limited land clearing to design appropriate offsets for the duration of the exploration phase.

"As a carbon neutral gold operation, Fenn-Gib will account for all carbon emissions over the life of the project and, to the greatest extent possible, aim for zero emissions," president and CEO Patrick Evans said.

"Our commitment starts immediately during the project's exploration phase and will continue as we embark on the pre-feasibility study in early 2022 for the initial mine design."

The company said the environmental and commercial benefits of relying on renewable energy and having its entire mobile fleet based on battery electric or fuel cell electric motors were "strongly compelling".

Mayfair acquired the project from Pan American in December.

Fenn-Gib has an indicated 2.08 million ounce gold resource and 75,000oz inferred.

Mayfair has a 50,000m drilling campaign underway, aiming to increase the resource to plus-3Moz by year-end.

It reported intercepting 241.1m at 1.67g/t from 11.5m at Fenn-Gib in June.

The company debuted on the TSX Venture Exchange in March after closing a C$19.8 million IPO with shares issued at C$1.85 and $2.62 per flow-through share.

The company had $13.2 million in working capital at June 30.

Its shares closed down 2.2% to 88c yesterday, valuing it at $68 million (US$54 million).
