Diavik mine A21 pipe development, Canada
Name and Location
Diavik mine A21 pipe development, Canada.
Client
The Diavik Joint Venture, comprising Rio Tinto (60%) and Dominion Diamond Corporation (40%).
Project Description
The development of a fourth pipe, known as A21, at the remote subarctic Diavik mine site, has been approved by Rio Tinto.
The A21 development will require rockfill dyke construction to encircle the orebody, just offshore of existing mining operations at Lac de Gras. Diavik will use the same innovative design and engineering technologies used to build the mine’s two other dykes, which have enabled the mining of three existing pipes.
The A21 production will provide an important source of incremental supply for Diavik, ensuring the continuation of existing production levels.
