Queensland coal production for the quarter ended 30 June 2000 was lower compared
with the corresponding quarter last year, primarily due to the sale of Moura
mine effective August 1999. Lower production at Peak Downs and Saraji was due to
wet weather and maintenance shutdowns. Lower production at Riverside reflects
the timing of shipments during the quarter. Production at Illawarra collieries
was higher than for the corresponding quarter last year due to the timing of
longwall change-outs. Increased coal production at USA mines for the fourth
quarter reflects customer demand.

WA iron ore production and shipments for the fourth quarter were significantly
higher than for the corresponding quarter last year, capitalising on strong
market demand. BHP WA operations shipped a record 6.172m dry tonnes (6.57m wet
tonnes) through its Nelson Point and Finucane Island berths at Port Hedland in
June. This was a significant milestone in capturing value from recent capacity
expansion and business improvement initiatives.

BHP's WA HBI plant is continuing to produce briquettes while undertaking trials
to determine the technical feasibility of production processes.

Production of copper in concentrate for the quarter ended 30 June was lower than
for the corresponding quarter last year largely due to the cessation of
production at BHP's North American copper operations in June 1999. Production of
copper in concentrate at Escondida was lower due to significantly lower average
head grade. Increased Tintaya production of copper in concentrate was due to
higher head grade and mill recovery.

Ekati diamond mine is at full production following commissioning of the mine
operations in October 1998.

Cannington silver production and shipments were higher for the fourth quarter
compared to the same quarter last year due to higher grade ore and increased
plant feed.

Raw steel production (core steel operations) for the quarter ended 30 June was
lower than for the corresponding quarter last year due to industrial disputation
at the Glenbrook Steelworks in New Zealand. Higher domestic despatches from
offshore core steel operations were due to increased customer demand. 

Raw steel production (discontinuing steel operations) was lower for the fourth
quarter compared to the corresponding period last year due to the closure of
Newcastle primary steel operations in September 1999. Sydney Steel Mill is
continuing to operate at peak levels and production from Whyalla Steelworks was
also higher compared to the corresponding quarter last year. Higher output from
Delta, Ohio, is due to the plant operating at rated capacity. Lower export
despatches from Newcastle and Whyalla was due to the cessation of export billet
production following the closure of the Newcastle operations.

Oil and condensate production for the fourth quarter was higher compared to the
corresponding quarter last year largely due to new production from the
Laminaria/Corallina and Buffalo fields. Production from Buffalo was lower in May
and June than for previous months due to the onset of water production and
maintenance shutdown. As at mid-July Griffin production had increased to 60 000
bopd (gross) from its previous level of around 36 000 bopd as a result of the
tie-in of the Griffin 8 and Scindian 3 infill wells. Production from Liverpool
Bay was considerably higher compared to the previous year, as production was
curtailed for much of the corresponding period in 1999 due to a minor oil spill.
Production from Bruce for this quarter was lower compared to fourth quarter last
year due to a planned shutdown of the facility.
