Established as a coal-mining venture in Thailand in the early 1980s, Banpu has since expanded into
Indonesia and China. In 2008 Banpu sold around 18.5 million tonnes of coal from existing assets and plan
to sell approximately 20.5 million tonnes of coal this year from Indonesian coal mines. At the end of 2008,
the Company had total attributable coal resources of 2,140.62 million tonnes, while its coal reserves were
approximately 600 million tonnes. Banpu is one of the leading coal producers in Asia.

Thailand
Mining operations in Thailand have been closed since the end of 2008 due to depletion of their coal reserves. These coal mines are now under rehabilitation stage.

Indonesia Banpu was quick to establish a local presence in Indonesia in 1991 and by 1998 had successfully developed and commissioned its first greenfield open-pit operation at Jorong in Kalimantan. In 2001 and 2002 Banpu became one of Indonesia’s leading coal producers through the two-staged acquisition of the Indocoal group with coal assets in Kalimantan and Sumatra.

In the year prior to acquisition, the operational Indocoal mines at Indominco and Kitadin had combined
production of only 4 million tonnes per annum but through rationalization and investment by 2009 the
acquired assets generated around 20.5 million tonnes of coal.

Currently, Banpu manages five coal mines in East Kalimantan namely Indominco, Jorong, Kitadin, Trubaindo
and Bharinto via its 73.72% owned subsidiary, PT. Indo Tambangraya Megah Tbk or ITM. (See more details
at http://www.itmg.co.id) Banpu's Indonesian mines produce a range of bituminous and sub-bitunous thermal
coals suitable for both export and domestic consumption. The Company supplies coal to utilities and
commercial users in the 'premium' East Asian markets (Japan, Hong Kong, South Korea and Taiwan) as well
as customers in India, Europe and South-East Asia including Indonesia, Malaysia and Thailand.

China
In 2003, Banpu took its first step into the Chinese coal industry by acquiring 21.6% stake in Asian American
Coal Inc. (AACI).  The Company later in June 2008 increased its shares in AACI to 100% by acquiring an
additional 78.4% shareholding from AACI’s major shareholders.  AACI is currently engaged in the investment and development of coal mining business in the People’s Republic of China by holding 56% stakes in Shanxi Asian American – Daning Energy Co., Ltd. (DANING) and 45% in Shanxi Gaohe Energy Company Ltd. (GAOHE).  DANING and GAOHE have been granted a 25 years and 30 years concession respectively, to undertake the development and production of coal mines in Shanxi Province. The DANING mine uses the underground longwall mining technology, a sophisticated and highly efficient underground coal mining technique. The DANING mine has its current production of 4 million tonnes of anthracite coal per annum while the GAOHE mine is now under construction expected to commence coal production in the year 2010, with designed capacity of 6 million tonnes per annum.

In 2005, Banpu and Hebi Coal and Electricity Co., Ltd. (HCEC) formed a new joint venture company –
Hebi Zhong Tai Mining Co., Ltd. (HZTM) to operate HEBI mine in Henan Province. Banpu holds 40% stake
in HEBI mine which has its current production capacity at 1.4 million tonnes per annum.

Banpu expects further growth potential in the Chinese coal sector through existing partnerships and other
new ventures.
