The Rio Tinto-owned Diavik diamond mine has been awarded the Northwest Territories (NWT) Mining and Exploration (MAX) special achievement award for the design, construction and operations of its dykes and its contribution as a joint venture partner to the Tibbitt-to-Contwoyto winter ice road.
The NWT MAX awards are a partnership between the NWT & Nunavut Chamber of Mines and the NWT government’s Department of Industry, Tourism and Investment. The awards recognise major contributions to the Northwest Territories’ minerals industry, the largest private sector contributor to its economy.
Diavik’s three award winning rock-fill dykes are an integral part of its life of mine plan enabling safe access to underwater deposits whilst keeping the pristine waters of Lac de Gras at bay. The most recent rock-fill dyke was constructed to encircle the ore body of Diavik’s fourth diamond pipe, known as A21. It took 3 million tonnes of rock to build the 2.2 kilometre embankment which has a maximum depth of 30 metres.
Diavik Diamond Mines president and chief operating officer Patrick Boitumelo said “We are delighted and honoured to receive this award, which is a testament to the pioneering spirit of everyone at Diavik.”
The Tibbitt to Contwoyto winter ice road was also the recipient of a special achievement award. This seasonal highway is a vital supply artery for the three operating diamond mines in the Northwest Territories. Director of winter road operations Ron Near said, “We are honoured to be selected by the committee. This award is a testament to the collaborative work done between the three joint venture partners. Operating in such remote areas with challenging technical constraints brings the best out of respective teams, we look forward to another successful Winter Road season in 2019.”
