BHP Billiton has approved the Misery open pit project at its EKATI Diamond Mine in Canada.
The project consists of a pushback of the existing Misery pit which was mined up until 2005.
Stripping operations are expected to begin October this year and ore production in late 2015.
The execution phase is expected to cost $US323 million and Graham Kerr, President of BHP Billiton Diamonds and Specialty Products said the company is looking forward to continuing its involvement in Canada.
“Since it started production in 1998, EKATI has been a cornerstone of the economy of the Northwest Territories and has contributed enormously to local communities,” he said.
“With the approval of the Misery project, we are able to continue to make the most of the resources at EKATI and also continue our proud legacy,” he added.
