Shareholders approved the change of the Company’s name at the General Meeting held on 19 October 2026. In Côte d’Ivoire, TerraNova is contracted to earn interests in eight permits (one granted, seven under application), including the flagship Nielle Gold Project in the north. The remaining “CDI East” permits sit along the Côte d’Ivoire–Ghana border. All are located on fertile Birimian greenstone belts that host numerous multimillion-ounce gold deposits across West Africa.

Its Meeka South Gold Project carries a clear infrastructure advantage, sitting close to the Bluebird Gold Processing Mill (Westgold) and Meeka Metals’ Murchison Gold Project, with geology comparable to established regional producers.
