2.14 1.50 1.54
Processing volumes in the third calendar quarter of 2016 were
22% higher than in the same quarter of the prior year primarily due
to higher ore availability, particularly from A-418 which
experienced poor ground conditions in the third quarter of calendar
2015.
Diamonds recovered in the third calendar quarter of 2016 were
also 22% higher than in the same quarter of the prior year
reflecting higher processing volumes. Diamonds recovered in the
third quarter of calendar 2015 included approximately 40,000 carats
recovered from Coarse Ore Rejects (“COR”). Recovered grades were
also higher than the same quarter of the prior year, but below plan
in the quarter as a result of increased underground dilution as a
result of granite sloughing from the walls of the open pit. The
Diavik Diamond Mine team is in the process of assessing this
dilution increase and the possible impact on the remaining calendar
year production.
The development of the A-21 pipe continues to progress according
to plan. During the quarter, the closure of the dike was completed
before the end of the open water season.
