Aim-listed Stellar Diamonds has entered into a potential deal that will see its Tongo kimberlite diamond project, in Sierra Leone, merged with Octea Mining’s adjacent Tonguma kimberlite diamond project to form a single 250 000 ct/y mining operation. The move, which will effectively establish West Africa’s second-largest diamond mining operation, will significantly enhance production and operational margins as the assets are brought into production using the same infrastructure.
