Third
quarter production was strong across all the major products. New projects
in iron ore (Eastern Range), coking coal (Hail Creek), and diamonds (Diavik)
all increased volumes.
•
There
were no significant operational developments in the quarter.
•
Hamersley
produced record volumes of iron ore in what is traditionally the strongest
quarter of the year. August shipments through Dampier and Cape Lambert were
also at record levels.
•
The
first bauxite was fed into the Comalco Alumina Refinery in the third quarter
and continuous alumina production is expected in the fourth quarter of 2004.

Demand remained strong across the full product range, with most markets showing continued strength.
New long-term agreements were finalised with Sumitomo Metal Industries securing ten million tonnes per annum of iron ore sales from Hamersley and Robe over a ten year period, commencing in 2005.
This, together with other long term arrangements announced in the first half of the year, further underpins the current expansion programme due for completion at the end of 2005.
Australian operations achieved record production this quarter. Although less than anticipated, this was consistent with the traditional strength of third quarter performance. Shipments also
reached record levels at both Dampier and Cape Lambert in August.
Hamersley
Hamersley’s
production in the third quarter reflects the commissioning of the Eastern Range
mine and the completion of the first stage of expansion work at Yandicoogina.
Robe
River
Increased production and
sales from West Angelas were in line with the expansion programme.
Production from Pannawonica was affected by planned maintenance, but strong sales volumes underlined the recovery from the effects of tropical cyclone Monty.
Iron
Ore Company of Canada
Output was severely curtailed
at IOC due to industrial action for most of the third quarter. Operations recommenced
on a staged basis late in September, with ramp up to normal levels expected
early in the fourth quarter.

Production
from the new Hail Creek coking coal mine continued to ramp-up. Third quarter
shipments were above the initial capacity rate of 5.5 million tonnes per year
and a capacity expansion to eight million tonnes per year by 2006 was approved
by the joint venture in July 2004. The proportion of hard coking coal from the
Kestrel mine has increased in 2004, since mining has commenced in the new 300
series area.
Blair Athol production was in line with the previous three quarters.

Production of borates reflects some improvement in end use markets. Demand for boric acid remains strong. Although production at Richards Bay Minerals was interrupted in September due to a
furnace run-out, titanium dioxide feedstock sales volumes will not be affected. Demand for Rio Tinto Iron & Titanium's iron, steel, rutile and zircon co-products remained strong.
Production was strong at all smelters and refineries. Eurallumina refinery production was a quarterly record while production at Queensland Alumina Limited refinery was also above the second
quarter of 2004 and the corresponding period of 2003. Bauxite production has increased in 2004, in anticipation of the commissioning of the Comalco Alumina Refinery. The new refinery remains on track for continuous production in the fourth quarter
of 2004.

Kennecott Utah Copper
Third quarter and year to date mined copper production at Kennecott Utah Copper was below the corresponding periods of 2003, reflecting lower copper grades. By-product production volumes have
been affected by poor mineralogy for about two years, but gold and molybdenum grades improved in the third quarter.
Escondida
Third quarter copper production from Escondida reflected lower copper grades due to mine sequencing. Production in the first nine months reflects the return to the normal mine plan from the
beginning of the year and the ramp up of the Laguna Seca throughput.
Grasberg
Production from the Grasberg mine continued to ramp-up. Mining rates are gradually improving as bench development in the higher grade areas enables more efficient ore access.
Rio Tinto’s share of production is based on a preliminary allocation of volumes between the joint venture partners, Rio Tinto and Freeport McMoRan.
Other copper operations
Copper production from the Palabora underground mine has improved, due to higher volumes hoisted and improved grades, but remains below design capacity. Production from the new Lift 2 at
Northparkes commenced in the quarter.

Although still affected by tight mining conditions, output from the Argyle open pit began to improve in the third quarter. Ore processed continued to consist of lower grade ore from the open pit
supplemented by ore from stockpiles.
Diavik
Diavik continued to perform well. The process plant comfortably exceeded design capacity on a consistent basis.
Murowa
First diamonds were recovered from the small scale operation at Murowa.
EXPLORATION AND EVALUATION
Total pre-tax expenditure on exploration charged to the profit and loss account up to the end of the third quarter of 2004 was $126 million compared with $97 million in 2003.
Exploration drilling continued on copper targets in Peru, Chile, Mexico, and Alaska. Diamond exploration continued in India, Canada, Botswana, South Africa and Brazil. Iron ore exploration
continued in the Hamersley Basin (Western Australia) and the order of magnitude study for Simandou (iron ore, Guinea) was completed and the project handed over to Rio Tinto Iron Ore. Bauxite, coking coal, and nickel exploration was carried out in a
number of regions.
Evaluation work continued at Eagle (nickel/copper, US), Sari Gunay (gold, Iran), Resolution (copper/gold, US) and at Potasio Rio Colorado (potash, Argentina) where pilot solution mining began in
the third quarter. An agreement for the sale of a copper resource at Marcona in Peru to Chariot Resources was signed on 6 August 2004. The sale is expected to be completed by early 2005.
ASSET DISPOSALS
The restructuring of Rio Tinto Zimbabwe, as a result of which Rio Tinto will hold its interest in the Murowa diamond project directly but cease to be an ordinary shareholder of Rio Tinto Zimbabwe,
was completed on 8 July 2004.
