GLOBAL OPERATIONS

Western Australia


In Australia, AWAC operates as Alcoa of Australia (AofA), which runs an integrated aluminium business including mining, refining and smelting operations. In 2005, these operations produced approximately 8.1 million tonnes of alumina and 377,000 tonnes of aluminium metal.

In Western Australia, bauxite from the Huntly and Willowdale mines, supply AofA's three alumina refineries: Wagerup, Pinjarra and Kwinana. Together, these operations produce 15 per cent of the world's alumina. They are among the world's lowest cost alumina operations.

The alumina is shipped to AWAC's aluminium smelters in Victoria or to overseas customers in the United States, Canada, Europe, Middle East and South Africa.

AWAC owns 100% of the operations in Western Australia.

Victoria


In Australia, AWAC operates as Alcoa of Australia (AofA), which runs an integrated aluminium business including mining, refining and smelting operations. In 2005, the smelting operations produced 377,000 tonnes of aluminium metal.

In Victoria, AofA runs and operates the Point Henry aluminium smelter, which is 100% owned by AWAC. It also has a 55% controlling interest in the Portland aluminium smelter.

The smelters use the alumina feedstock produced by the Western Australian operations.

Alumina Limited Offices


Alumina Limited's offices are located in Southbank, Melbourne.

Huntly bauxite mine, Western Australia


AWAC sources bauxite from its 100% owned Huntly and Willowdale bauxite mines located in the Darling Range south of Perth. Former WMC Limited discovered bauxite in this region in the late 1950's which started the partnership with Alcoa.

Huntly produces bauxite that supplies AWAC's three alumina refineries in Western Australia. The mining leases provide access to bauxite to 2044.

Bauxite is transported from the mines by rail to Kwinana and by overland conveyor to Pinjarra and Wagerup. The close proximity of mine to refinery lowers operational costs.

Bauxite from Huntly is low in alumina grade and low in reactive silica. This results in low consumption of caustic soda, which further reduces production costs.

Willowdale bauxite mine, Western Australia


AWAC sources bauxite from its 100% owned Huntly and Willowdale bauxite mines located in the Darling Range south of Perth. Former WMC Limited discovered bauxite in this region in the late 1950's which started the partnership with Alcoa.

Willowdale produces bauxite that is supplied to AWAC's Wagerup alumina refinery in Western Australia. The mining leases provide access to bauxite to 2044.

Bauxite is transported from the mine by overland conveyor to Wagerup. The close proximity of mine to the refinery lowers operational costs.

Bauxite from the Darling Range is low in alumina grade and low in reactive silica. This results in low consumption of caustic soda, which further reduces production costs.

Wagerup alumina refinery, Western Australia (2.6mt)


Wagerup is the second largest alumina refinery in the AWAC global joint venture between Alumina Limited and Alcoa.

The Western Australian Government has granted approval for the planned capacity expansion of the Wagerup alumina refinery from 2.6 million tonnes per year to approximately 4.7 million tonnes per year.

Bauxite is transported from the nearby Willowdale mine by overland conveyor. The close proximity of mine to the refinery lowers operational costs and places these operations as amongst the world's lowest cost producers.

A storage and loading facility, which handles the majority of shipping for the refinery, is located at the nearby port of Bunbury.

Kwinana alumina refinery, Western Australia (2.0mt)


Kwinana alumina refinery has an annual capacity of 2.0 million tonnes.

Bauxite is transported from the nearby Huntly and Willowdale mines by rail. The close proximity of mine to refinery lowers operational costs and places this operation amongst the world's lowest cost producers.

A shipping facility is located close by to transport alumina production to AWAC's aluminium smelters in Victoria and overseas customers.

Pinjarra alumina refinery, Western Australia (4.1mt)


Pinjarra is AWAC's largest refinery. With production capacity of 4.1 million tonnes, it represents 7% of the world's alumina refining capacity. The 657,000 tonne efficiency upgrade will be fully commissioned by Q4 2006.

Bauxite is transported from the nearby Huntly mine by overland conveyor. The close proximity of mine to refinery lowers operational costs and places these operations amongst the world's lowest cost producers.

A storage and loading facility that handles the majority of shipping for the refinery is located at the port of Bunbury. Some Pinjarra production is transported through the shipping facility at Kwinana.

Point Henry aluminium smelter, Victoria (185kt)


Point Henry has an annual capacity of 185,000 tonnes of aluminium. Almost 50% of this aluminium is sold to the nearby Kaal Australia rolling mill which is not an asset of AWAC. Most of the electricity for the Point Henry smelter is supplied by Alcoa of Australia's generating station at Anglesea, with the balance required available under a 30-year electricity supply agreement that expires in 2014.

Portland aluminium smelter, Victoria (190kt - 55% owned)


The Portland smelter has an annual production capacity of 345,000 tonnes of aluminium and is 240 kilometres west of Geelong. AWAC has a 55% controlling interest in the smelter and manages its operations. Partners are CITIC (22.5% owners) and Marubeni (22.5% owners). Alcoa manages the smelter operations.

In 2003, Portland production increased 3% (AWAC's 55% beneficial interest in production).

Electricity for the Portland smelter is purchased under a 30-year electricity supply agreement that expires in 2016.

 

United States

Point Comfort, Texas (2.3mt)


Point Comfort alumina refinery in Texas is 100% AWAC owned. It has an annual capacity of 2.3 million tonnes.

In 2002, production was 1.4 million tonnes. Production rate increased to 2.0 million tonnes during 2003. Most of the refinery's smelter-grade alumina is sold to Alcoa's smelters in the United States.

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 is also purchased in the spot market from Jamaica and French Guyana.

 

Jamaica

Jamalco


Jamalco is a 50/50 joint venture between AWAC and a Jamaican Government business. Jamalco owns and manages bauxite mines, an alumina refinery and port facilities.

Bauxite mines are 40 kilometres to the north of the refinery in the Mocho Mountains and mining rights are owned by Jamalco. Bauxite operations are jointly undertaken by AWAC and Alpart, a joint venture owned by Kaiser Aluminium and Hydro Aluminium of Norway

Bauxite is transported to the refinery on a railway owned by Jamalco, which also manages a nearby port.

Clarendon refinery


Jamalco's Clarendon refinery, 70 kilometres west of Kingston, has an annual capacity of 1.25 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. In July 2005, plans were approved for AWAC to participate in a 1.5 million tonne expansion of the Jamalco refinery that will increase production capacity to 2.8 million tonnes. As part of the expansion project, AWAC's ownership in Jamalco will move from 50% to approximately 77%.

The 146,000mtpy first phase expansion of the Jamalco refinery is scheduled for mechanical comletion by end 2006.

The 1.35 million mtpy second phase expansion is subject to finalisation of an agreement to bring natural gas to the refinery and changes to the joint venture agreement.

Costs have reduced following the Jamaican government's removal of the 28-year bauxite levy, effective early 2003.

Oil-powered turbines provide energy to the refinery and surplus power produced is sold into the Jamaican public electricity grid.
