Diavik Diamond Mine A21 OrebodyTuesday, November 19, 2019 - 4:00pm to 4:20pm Theatre Two
Diavik’s newest orebody, the A21 kimberlite pipe, was brought into production in December 2017 when surface mining began. This is the fourth kimberlite pipe to be mined at the Diavik Diamond Mine, located at Lac de Gras, 300 kilometres northeast of Yellowknife. To access this underwater orebody, Diavik constructed an engineered, 2.1 km long rock fill water retention dike during 2014 to 2017. This has now opened up the opportunity to study and evaluate possible mining methods below the open pit. Such additional kimberlite extraction would occur from 2023 to 2025.
