Aim-listed IronRidge Resources has secured a first-mover advantage over a potential major new gold discovery in Chad after entering into a conditional share subscription agreement with private Singapore-registered company Tekton Minerals. The Africa- and Australia-focused mineral exploration company will invest up to $3.5-million to acquire up to 58% of the shareholding in Tekton and, subsequently, obtain access to exclusive rights over five exploration permits covering 1 000 km2 and reconnaissance licences covering 400 km2 within the Ouaddaï province.
