Processing volumes in the fourth calendar quarter of 2016 were 16% higher than in the same quarter of the prior year due to the extended planned maintenance shutdown in the processing plant during the fourth quarter of calendar 2015.

Diamonds recovered in the fourth calendar quarter of 2016 were 10% higher than in the same quarter of the prior year, reflecting higher processing volumes that were partly offset by lower recovered grade.

Diamonds recovered in calendar 2016 of 6.7 million carats were 4% higher than in calendar 2015, but 4% lower than the revised calendar 2016 plan of 6.9 million carats. Lower-than-expected diamond recovery reflected lower grades due to underground dilution, which resulted from granite sloughing from the walls of the open pit.

The completion of A-21 dike construction and the start of dewatering are expected during calendar 2017, in accordance with the project plan.

A new mine plan and budget for calendar 2017 is under review by Rio Tinto plc and the Company.

Mining activities will be exclusively underground. Processed ore will be sourced from the following kimberlite pipes in the approximate proportions noted below:

Production from Coarse Ore Rejects (“COR”) is expected to be negligible in 2017. Production from COR is not included in the Company’s ore reserves, and is therefore incremental.

The aforementioned mine plan for the Diavik Diamond Mine was prepared and verified by Diavik Diamond Mines (2012) Inc. (“DDMI”), operator of the Diavik Diamond Mine, under the supervision of Calvin Yip, P. Eng., Principal Advisor, Strategic Planning of DDMI, and a Qualified Person within the meaning of National Instrument 43-101 of the Canadian Securities Administrators.
