only

those

mineral

deposits

that

the

company

can

economically

and

legally

extract.

Certain

terms

in

this

presentation,

including

“resource”,

“mineralisation”

and

“potential

mineralisation”,

would

not

generally

be

permitted

in

an

SEC

filing.

The

material

denoted

by

such

terms

is

not

proven

or

probable

Reserves

as

such

terms

are

used

in

the

SEC's

Industry

Guide

and

there

can

be

no

assurance

that

BHP

Billiton

will

be

able

to

convert

such

material

to

proven

or

probable

Reserves

or

extract

such

material

economically.

for

you

to

Blast Furnace Production Inputs

Slide 9

Blast furnace steel production is continuing to increase

•

66% of global crude steel is currently

generated via blast furnaces

•

Blast furnace production and

share is

continuing to rise

•

Trend is to larger, higher productivity

furnaces

•

China’s steel policy is supportive of this

move and the shift towards blast furnace

•

Shift in size and efficiency demands will

require high-quality raw materials

BHP Billiton’s businesses are leaders in their own right

•

BHP Billiton is the only mining

company with a top three marketing

position in all three steel raw material

groups

•

Australian based operations have a

significant location advantage with

close proximity to Asian growth

market

•

Expected mineralisation base will

support metallurgical coal and iron

ore production lives of >50 years

•

We are aggressively expanding

Three large, low cost, high quality and expandable businesses

•

Production is expected to triple between 2007 and 2015 –

benefits of

operational scale and simplicity

•

High quality resources, and low costs of production

•

Large resource base in close proximity to key growth markets

Iron Ore

Metallurgical

Coal

Manganese

•

Bowen Basin produces ~64% of the global seaborne metallurgical coal

•

Large, low cost operations, supplying extremely high quality products to

customers

•

Resource base and infrastructure provides growth optionality

•

Unique high grade ore position

•

High value in use is being reflected in price

High grade ore has significant value in use benefits

Source: BHP Billiton estimates.

a) Assumed ore inputs for example of 40% domestic ore (25% Mn), 20% imported ore (44% Mn) and 40% rich slag (33% Mn).

•

Low grade ore performance in alloy

production is substantially inferior

•

Using low grade ores:

–

Increases input costs

–

Produces a greater amount of

slag output

–

Decreases volume of saleable

product

–

Decreases quality of final

product

•

High grade ore therefore has a

higher value in use
