Mountain Province holds 49% of the mine, with operator De Beers Canada holding 51%. 

The mine suspended production early February after reporting several cases of COVID-19.

The ramp-up follows an essential services team crew change, which included bringing in two industrial hygienists to review and oversee work protocols and further deep cleaning.

Essential services include maintaining power, water treatment, clearing roads, time critical maintenance work, water management, and receiving incoming winter road fuel and cargo shipments. 

The next step is to bring in the production crew later this week and to begin the build up to production over the weekend. 

Mountain Province chief executive Stuart Brown said: "Plans to mitigate the loss of production are being assessed and will continue to be reviewed over the coming weeks. It is important to keep our focus on maintaining a safe and secure site while balancing the need to make up for lost production as we navigate our way through the pandemic."

De Beers Group is controlled by Anglo American PLC.
