Point Comfort alumina refinery, Texas
Point Comfort alumina refinery in Texas is 100% AWAC owned and has a nominal annual capacity of 2.3 million tonnes of alumina. The refinery produces smelter-grade alumina and alumina hydrates (chemical –grade alumina). Point Comfort uses gas-fired cogeneration facilities to supply process heat and power to the refinery. In late 2008, 550,000 mtpy of alumina production was curtailed as a result of the global market conditions. Point Comfort is 210 kilometres south of Houston on Port Lavaca Bay. Port facilities are linked to the Gulf of Mexico through a 35-kilometre channel. Bauxite is sourced from AWAC's affiliate in Guinea and from MRN in Brazil. |

Clarendon alumina refinery, Jamaica
Jamalco's Clarendon refinery, 70 kilometres west of Kingston, has an annual capacity of 1.4 million tonnes. The joint-venture partners are responsible for marketing their own share of production. During 2003 annual production capacity was increased by 250,000 tonnes to 1.25 million tonnes following a US$115 million expansion. A 146,000 mtpy further expansion of the Jamalco refinery was completed in 2007. Oil-powered turbines provide energy to the refinery and surplus power produced is sold into the Jamaican public electricity grid. |

Moengo bauxite mine, Suriname
Located in north-east Suriname, the Moengo mine is 100% owned by Suralco. Bauxite is barged 200 kilometres to the refinery at Paranam. With respect to the Paranam refinery, at current rates of production it is likely that the supply of bauxite from existing sources in eastern Suriname will be exhausted in the next several years. Other alternative sources of bauxite are being evaluated in eastern Suriname, for potential development over the period 2011 to 2013. |

Paranam alumina refinery, Suriname
The 2.2 million tonnes-per-annum alumina refinery at Paranam sources bauxite from the Moengo mine. AWAC wholly owns the bauxite mining and alumina refining operations in Suriname following the July 2009 acquisition on the BHP Billiton subsidiary that was 45 per cent joint venture partner. In May 2009, the Suralco alumina refinery announced a curtailment of 870,000 metric tonnes per year. The curtailment was aimed at deferring further bauxite extraction until additional in-country bauxite resources are developed and market conditions for alumina improve. |

Juruti bauxite mine, Brasil
The Juruti operations, which are part of the Alcoa World Alumina and Chemicals (AWAC) joint venture with Alcoa consists of a port facility, a mine and a 50 kilometre rail system to the port. Initial output at the mine will ramp up to 2.6 million metric tons per year (mtpy). Bauxite from Juruti will be shipped to the Alumar alumina refinery in Sao Luis, Brazil which has undergone a 2.1 million mtpy expansion program that will bring total production there to 3.5 million mtpy. Following the expansion, Alcoa Aluminio and AWAC combined hold a 54 percent share of the refinery. The remaining share is held by BHP Billiton (36 percent) and Rio Tinto Alcan (10 percent). |

Alcoa Steamship Inc.
AWAC owns and operates a shipping operation that provides transport for AWAC's alumina business and to third parties, including Alcoa. Operating seven owned and other chartered vessels, this business transports bauxite, alumina, caustic soda, fuel oil, petroleum, coke and limestone. Two large carriers operate between Australia and the United States, carrying alumina to smelters on the west coast of the United States and backfilling with raw materials such as petroleum, coke and caustic soda for the Australian alumina operations. Three smaller vessels operate in the Caribbean carrying alumina from Suriname and Jamaica to the south and north coasts of the United States. These ships are also backfilled with raw materials for the Suriname and Jamaican operations. AWAC operates two 30,000-tonne-vessels that transport alumina from the West Australian refineries to the Victorian aluminium smelters. AWAC also charters carriers to transport bauxite, alumina and aluminium between its various global operations. |
