Planning process

On 20 January 2016 it was reported that the deadline for the feasibility study for the Jatobá plant had been extended to December 2016, and the deadline for the Jamanxim plant feasibility study was now 31 December 2017.
A "platform" approach is proposed for construction to minimise environmental impact.
There would be no access roads, and workers would be taken to the site by helicopter.
After construction is complete the site would be regenerated.
