XXIX Advances Opemiska Development with Launch of Environmental and Social Baseline Studies

Executive Summary

• XXIX Metal Corp. has engaged GCM Enviro Synergies to conduct baseline environmental and social studies at its Opemiska Project in Quebec, advancing the asset toward a Prefeasibility Study.
• The assessment will generate critical datasets on water, soil, wildlife, vegetation, land use, and socio-economic conditions to support future regulatory submissions, engineering studies, and permitting.
• Fieldwork is scheduled to begin in the coming weeks, building on the October 2025 Preliminary Economic Assessment that outlined a highly economic open-pit copper operation.
