Oyu Tolgoi
China
Mongolia
India
• The Oyu Tolgoi copper deposit was discovered in the 1980’s.
• It is located 550km south of Ulaanbaatar and 80km north of the Mongolia-China border.
• It represents a broader industry trend of copper being extracted from deposits in emerging
regions.
• It is a significant development for the Mongolian people, requiring engagement with
governments and communities.

Demand is driven by consumption needed to achieve
China’s phenomenal growth
GDP per capita in China still only 14 per cent of that in the United States.
There are only 33 automotive vehicles for every 1,000 people in China
compared to 800 in the United States.
By 2025, it’s estimated that 221 Chinese cities will have a population of at
least a million people. Of these, 23 will have over 5 million people.
China will build between four and five million new buildings between
2005 and 2025: Roughly equal to 50,000 skyscrapers or the
equivalent of up to ten cities the size of New York.

Copper is essential to everyday life
Properties of copper Importance to everyday life
• Ductile, corrosion-resistant, malleable,
recyclable and also a highly efficient
electrical conductor, second only to silver.
• Alloys have additional characteristics like
hardness, tensile strength and greater
corrosion-resistance.
• Used in heating, architecture, plumbing,
transport, communications as well as
conventional and renewable energy.
• The average home today contains about
200 kilograms of copper.
• Around 25 kilograms of the average
family car is copper and copper alloys.

7. 6
New applications for copper
Hybrid electric vehicles Antimicrobial benefits
• Electric and hybrid electric vehicles have
a much higher copper content than
conventional vehicles.
• ICA predicts that the full adoption of the
IE2 standard will increase copper use by
an average 0.56kg/kW.
• Copper has antimicrobial properties.
• It is proven to inactivate and limit the
spread of various influenza and bacteria
strains.
• It can continuously kill bacteria and
remains effective even after repeated wet
& dry abrasion and re-contamination.

8. 7
Copper – A sustainable metal
• Unlike many other raw materials, copper is
100% recyclable.
• In 2007, recycled copper accounted for
35% of consumption.
• Copper recycling involves reclaiming
‘secondary copper’ from products that have
reached the end of their life.

• There is a trend towards greater supply
from developing countries.
• Currently 60% of production comes from
the top five copper mining nations
– Chile, Peru, USA, China & Indonesia.
• 10% is sourced from OECD member
countries and the remaining 30% sourced
from non-OECD countries.
• 44% of the potential new capacity to
be added before 2020 will come from
non-OECD countries.

The mining industry can serve as a foundation for
developing economies
Escondida still represents the largest foreign investment in Chile
China
• Escondida has made significant contributions to the
economy of Chile.
• In 2008 Escondida accounted for 8% of global copper
production and 24% of Chile’s national production.
• Accumulated investment in the project over the past
20 years has been US$7 billion.
• Tax contributions to the Chilean treasury from
Escondida and its owners since 1991 amount to
US$10 billion.1
• In 2006, company exports accounted for 10% of the
country’s total export revenues.
• The company represented more than 4% of the
Chilean GDP in 2006.2
Note: 1. Tax contributions comprise of First Category Income Tax, Additional Withholding Tax Paid On Owners’ Dividends and Royalties as at December 31st 2008.
2. Value includes both direct and indirect effects.

Chile has successfully developed its economy
through revenue derived from natural resources
A well-planned framework has allowed Chile to take advantage of revenues
• Responsible & predictable fiscal policy
• Independent monetary policy
• Control undesirable externalities
• Develop strategic industries
• Allow diversification of imports and exports
• Competitive and well capitalised banks
• Prudent regulation and supervision
The copper industry contributed to 14% of GDP in 2009.
It also represented 51% of all exports which were valued
at US$27.5 billion.
