Ngemuva kohambo olunabile lwabakhiqizi be-dredge emhlabeni wonke kanye nemishini ekhona yendawo eyakhiwe ngayo, abakwaFigjarloo Joint Venture banikeze u-Ellicott® iphrojekthi ye-turnkey ukuklama nokwakha indawo yabo yokuhlala, "COOLJARLOO I", yezimayini zamaminerali ezisindayo eNtshonalanga Australia. Umugqa wamasondo omabili omgodi wamasondo, owaqala ukusebenza ngoDisemba 1989, wachazwa njengendawo enkulu kunazo zonke yezimbiwa zamanzi ezinesihlabathi emhlabeni kanye nesakhiwo esikhulu kunazo zonke kunoma yiluphi uhlobo e-Australia.
