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 atleast 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.

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.

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.

Rio Tinto’s robust pipeline of greenfield projects

Notes: 1. Copper assets include those in Pre-Production or Feasibility and the ten largest assets with Active Reserves Development as defined by MEG.2. Rio Tinto’s owns 100% of La Granja, 55% of Resolution, has a 22.4% interest in Ivanhoe Mines Limited (with the option to increase to 44%) who own 66% of Oyu Tolgoi and a 19.8% interest in Northern Dynasty Minerals Limited who own 50% of Pebble. Deposit data for La Granja, Resolution and Oyu Tolgoi is from the JORC compliant ore reserves and resources statement outlined in the 2009 Annual Report, pp. 68-77. Pebble deposit data is 43-101 compliant, derived from the “Updates Mineral Resource Estimate…” news release dated 01/02/2010.

• 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

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.
