Project summary

Critical Elements Corporation plans to operate an open pit lithium-tantalum mine on the Rose property, which is located approximately forty kilometres north of the Cree village of Nemaska on the territory of the Eeyou Istchee James Bay Regional Government. The mined ore will be processed to produce both spodumene and tantalum concentrates. The daily production target is 4,600 tonnes of ore, with an expected operating life of 17 years. The planned infrastructure on the site includes an open pit, an ore concentration plant, tailings storage areas and mining water management facilities. The Rose property is accessible from the road that links the Cree village of Nemaska to the Eastmain 1 powerhouse. The project also requires moving a section of the 315 kV Eastmain-1-Nemiscau power line to the east, which will be handled by Hydro Quebec.
