Louis-Pierre Gignac, President & Chief Executive Officer, commented: "Thanks to our shareholders, team members, local stakeholders and other supporters, 2022 has been a transformational year for GMIN. As 2022 drew to a close, I am extremely gratified to take stock of some of what we have accomplished as a team. I look forward to leading this team to make continued excellent progress on all fronts on our TZ project using our proven self-perform approach. I am excited for GMIN's future as we continue to target commercial production at TZ in the second half of 2024, and I look forward to growing the Corporation using TZ as its cornerstone asset. I would like to offer my thanks for everyone's contribution and support to what has been an outstanding year for G Mining Ventures Corp."

Additionally, GMIN is committed to social and environmental responsibility in all its activities.

• The Project is expected to create up to 1,200 jobs during the construction phase and over 600 permanent jobs during the operation stage

• In addition to powering the project through 80% renewable energy, the transmission line will become part of the state utility infrastructure, providing reliable power to the region
• Construction of a bypass road in Jardim do Ouro to improve safety by diverting heavy traffic from current industrial activities by other companies (and future GMIN operations) away from the village

In closing, GMIN is on the cusp of an exciting new phase, made possible by the experience, ability, innovation, and can-do attitude of the GMIN team.
