Update on Diavik Mine Plan: Flexible Production to Adapt to Changing Market
In calendar 2009, it is estimated that 1.3 million tonnes of open pit ore will be mined, the majority of which will come from the A-418 kimberlite pipe, with the remaining production coming from the A-154 South open pit. However, if market conditions improve, additional carats can be produced by shifting the mix of ore from A-418 to the higher grade A-154 South. Total carat production is expected to be between 5 and 6 million carats on a 100% basis.
In calendar 2010, the A-418 kimberlite open pit is expected to be the primary ore source supplemented by A-154 South, where open pit mining is planned to be complete by the second quarter. Total open pit ore mined is expected to be 1.5 million tonnes. In addition, underground mining is scheduled to commence on a limited scale with approximately 0.5 million tonnes of ore during the year, sourced mainly from the A-154 North pipe.
In calendar 2011, underground mining is expected to ramp up to 0.9 million tonnes a year, principally from the A-154 North and South pipes. Production from the A-418 open pit is expected to peak at 1.5 million tonnes as the strip ratio is reduced during the later phases of open pit mining.
In the absence of production from A-21, calendar 2012 is expected to be the final year of open pit mining. An amended pit plan for A-418 is expected to allow the open pit depth to be extended by 10 meters to 9200 elevation, reallocating 240,000 tonnes of A-418 ore from underground to open pit for a total of 0.3 million tonnes from open pit in calendar 2012. Underground mining in 2012 is expected to reach approximately 1.0 million tonnes.
By 2013, underground mining is expected to reach its ongoing capacity of 1.5 million tonnes a year with a blend of ore from A-154 North, A-154 South, and A-418. Additional production capacity beyond 1.5 million tonnes a year or to extend production beyond 2022 will be dependent on, among other things, bringing resources and exploratory tonnages in to reserves.
Cost of Sales
The summer and winter production shutdowns are planned to last six weeks each, during which time diamond production will temporarily cease and the mine will be placed on a short-term care and maintenance schedule. The summer shutdown is scheduled for

Cost of sales for the mining segment for fiscal 2009 included proceeds of an insurance settlement related to a Diavik Diamond Mine shovel fire and significant costs attributable to development activity versus production activity during the A-418 pre-production period. After adjusting for these factors, the Company expects cost of sales for the mining segment to increase in fiscal 2010 by an estimated 10% to approximately
The expected increase in cost of sales for fiscal 2010 is specific to the Company’s mining segment and is not indicative of the trend in operating costs at the Diavik Diamond Mine. On a Canadian dollar basis cash operating costs at the mine are expected to be slightly lower in calendar 2009 compared with calendar 2008.
During the next three years, the Company’s portion of the planned capital expenditure is expected to be approximately U.S.
The Diavik Diamond Mine is one of the highest operating margin diamond mines in the world. Even in these distressed and uncertain times it delivers a significant cash margin as a producer of a premium diamond product in a secure political environment. It has a reserve and resource base to take it well into a future of improved demand as world economic recovery meets a fundamentally undersupplied diamond market.
