Newmont Starts Up at Boddington
One of three electric rope shovels currently in service at Newmont Mining’s million-oz-per-year
Newmont Mining produced the first gold
and copper concentrate at its Boddington
mine in Western Australia in mid-August
2009, following start of operations in late
July. Ramp-up to design capacity is
expected to take about 12 months.
Production over the first five years of
operation will average about 1 million oz/y
of gold and 30,000 mt/y of copper in concentrate.
Costs applicable to sales, net of
by-product credits, are expected to average
$300/oz of gold over the same period.
Capital costs are expected to come in at
between $2.8 billion and $2.9 billion.

OIn addition to its gold production, Boddington will provide Newmont with approximately 30,000 mt/y
of copper in
concentrate. Project cost is estimated at $2.8-$2.9 billion.
Boddington has been developed as a
large open-pit about 130 km southeast of
Perth and at full capacity will be
Australia’s largest gold mine. Proven and
probable gold reserves total 20 million
oz, and mine life is estimated at more
than 24 years.
The Boddington deposit is located
within the Saddleback greenstone belt, a
fault-bounded sliver of Achaean volcanic
and shallow intrusive rocks surrounded
by granitic and gneissic rocks. Pit dimensions
will reach 1,000 x 4,000 m at the
surface and an ultimate depth of 700 m.
Mining equipment includes more than
30 Cat 793 haul trucks, three electric
rope shovels, and one hydraulic shovel. A
2.2-km-long overland conveyor delivers
ore to the mill.
Mill equipment includes two 60 x 110
primary crushers; four high-pressure
grinding rolls; five MP 1000 secondary
crushers; and four 26-ft x 44-ft ball mills,
which are equipped with the largest twinpinion
drives produced to date.
