Diavik Diamond Mine - 2008 third quarter update


    YELLOWKNIFE, Nov. 18 /CNW/ - Diavik Diamond Mines Inc. (DDMI), the
operator of the Diavik Diamond Mine is pleased to provide this report for the
third quarter 2008.
    During the quarter, crews mined from both ore bodies contained in the
ever deepening and maturing A154 open pit. Progress in the new, adjacent open
pit contributed over half of mining production from Diavik's third ore body,
the A418 kimberlite pipe. Diamond production in the quarter reached 2.321
million carats, bringing annual production to the end of September to 6.628
million carats.
    At quarter's end, there were 799 workers operating the mine. As per
Diavik's commitments to local communities, approximately two thirds were
northern residents, and of these, over half were of Aboriginal descent.
    Steady progress continues to be made in the new underground mine.
Approximately 10 kilometres of tunnelling have been completed underground, and
work continues to progress on maintenance shops, water pumping stations, and
ventilation facilities. On surface, work continues on the new crusher and past
backfill plants, expanded electrical generating and water treatment
facilities, and on mine change rooms and additional permanent accommodations.
Underground mining is currently scheduled to begin in 2009. It is estimated to
replace open pit mining by 2012, and will support Diavik's mine life beyond
2020.
    Diavik operates with the highest regards to safety and all who work at
Diavik contribute to its safety statistics. In a quarter of significant
construction activity related to the underground mine, there were seven lost
time injuries and six medical treatments. Year to date, there have been nine
lost time injuries and 10 medical treatments bringing the Lost Time Injury
Frequency Rate to 0.53 and the All Incident Frequency Rate to 1.12.
    Exploration continues in earnest on the Diavik property, marked by a
variety of geophysical and geochemical surveys and diamond drilling. A
highlight was the discovery of two new kimberlites, bringing the total number
discovered on the Diavik claims to 70. More follow-up work will be required to
test their economic potential.
    The Diavik Diamond Mine is located 300 kilometres northeast of
Yellowknife, Northwest Territories and is an unincorporated joint venture
between DDMI (60%) and Harry Winston Diamond Mines Ltd. (40%). Both companies
are headquartered in Yellowknife, Canada. DDMI is a wholly owned subsidiary of
Rio Tinto plc of London, England, and Harry Winston Diamond Mines Ltd. is
wholly owned by Harry Winston Diamond Corporation of Toronto, Canada. DDMI is
the operator of the project. For further information contact Tom Hoefer,
