The first concrete pour for the new mining plant at Namdebs Elizabeth
Bay diamond mine was recently officially celebrated and the project
is on track for commissioning in the first half of 2004.
BATEMAN was awarded the EPCM (engineering, procurement,
construction and management) contract in April 2003 to upgrade the treatment
plant at Namdebs Elizabeth Bay mine, near the Atlantic port of
Luderitz in Namibia, as part of the Elizabeth Bay Liberation Project.
The contract was awarded under a unique partnering arrangement with
a shared risk / shared reward incentive scheme. The extension project
will extend the life of the mine by 10 years and will more than double
the mines annual production in the first three years of operation,
and will remain 56 % above current levels for the remainder of the mines
lifespan.
Construction of the new plant commenced in May this
year and includes the installation of primary-, secondary- and tertiary-crushing
plants, two stages of primary screening and a ball-milling process.
An important feature is the installation of a wet-crushing system, the
first of its kind in the De Beers Group, as the current treatment plant
cannot process all ore types, making it impossible to treat all potentially
viable deposits. With the new system, the plant will be able to handle
clay-rich material and very hard, almost cemented layers that were previously
not treatable, as well as including ore from wet areas.
Sections of the mine are expected to be commissioned
between February and June 2004, while the ramp-up period will last from
July 2004 to April 2005.
Presently 650 workers are involved in the construction,
approximately 90 % of whom are Namibian, with a small percentage of
technical staff being drawn from South Africa.
The Elizabeth Bay mine contributes about 8 % of Namdebs
annual production (currently 1,3 million carats for 2003) and the extension
project should see the mine increase its contribution by 25 % in the
first three years and then by 12 % for the remainder of the mines
lifespan. By extending the life of the mine, 170 permanent jobs have
been secured and this, with a three-shift operation, will extend to
240 by mid 2004. With continuous operation scheduled for 2005, employment
will increase by an additional 47 employees.
