Australia’s rough diamond output will decline from 14.2-million carats to 137 000 ct once the Argyle mine closes in 2021, says data and analytics company GlobalData.
The company notes that the country’s rough diamond supply has been entirely reliant on output from the Argyle mine, in Western Australia, following the suspension of mining at the Ellendale mine in 2015, which followed the collapse of Kimberley Diamond Company in the same year.
