Marathon Gold Publishes 2022 Sustainability Report

TORONTO, ON – September 18, 2023 – Marathon Gold Corporation (“Marathon” or the “Company”; TSX: MOZ) has published its 2022 Sustainability Report for the Valentine Gold Project in the central region of Newfoundland and Labrador.

Matt Manson, President, and CEO commented “This is our second annual Sustainability Report for the Valentine Gold Project, a mining project under full construction. During 2022, we saw the completion of what was three years of social and environmental assessment for Valentine, with approvals to proceed to construction received from both the Newfoundland and Labrador and federal regulators. As I write this, we have completed approximately 11 months of construction, and are on track to deliver first gold in the first quarter of 2025.”

Matt Manson continued “With more than 440 people employed as either a contractor or Marathon employee, the Valentine Gold Project has already become one of Newfoundland and Labrador’s largest employers. The most important statistic in any mining project is health and safety, and I am proud that the 2022 Sustainability Report shows a safe workplace for our people. This will always take priority in our business. The report also describes our approach to the social, environmental, and cultural responsibilities we carry as the developer of what will be the largest gold mine in the Atlantic Canada region, and the largest mine of any type on the island of Newfoundland.”
