Alcoa Announces Cooperation Agreement with Vietnam on Development of Bauxite Mining and Alumina Refineries

WASHINGTON—(BUSINESS WIRE)—Alcoa (NYSE:AA) today announced the signing of a Cooperation Agreement with Vietnam’s premier minerals development company, Vietnam National Coal-Mineral Industries Group (Vinacomin), for cooperation in development of the aluminum industry in Vietnam.

Under the agreement, Alcoa World Alumina and Chemicals (AWAC) – a global alliance between Alcoa and Alumina Ltd, with Alcoa holding 60 percent — will conduct due diligence, on the acquisition of a 40 percent interest in the 600,000 metric tons per year Nhan Co alumina refinery that is to be constructed in Dak Nong Province in Vietnam’s Central Highlands, based on access to extensive reserves of high quality bauxite. If the transaction proceeds, the shareholding in the Joint Stock Company that owns the Nhan Co bauxite mine and alumina refinery will be Vinacomin 51%, AWAC 40% and other investors 9%.

In addition the parties have agreed to conduct a joint feasibility study on the Gia Nghia bauxite mine and alumina refinery project, also located in Dak Nong province, with first stage capacity expected to be between 1.0 and 1.5 million metric tons of alumina per year.

The agreement follows the recent permission granted to Vinacomin by the Government of Vietnam to establish Joint Stock Companies with foreign partners holding a maximum of 40 percent. Vinacomin is a state-owned company with a leading role in the development of Vietnam’s mineral resources.

In signing the Cooperation Agreement in presence of Vietnamese Prime Minister, His Excellency Mr Nguyen Tan Dung and US Secretary of Commerce Carlos Guiterrez, Alcoa Executive Vice President and President Alcoa Global Primary Products, Bernt Reitan, paid tribute to the role played by the governments of Vietnam and the United States in creating an environment of friendly cooperation between the two countries, and facilitating the engagement between the two companies, which began in 2006.

“Alcoa is delighted to be invited to participate in the development of the Vietnamese economy and particularly to be engaged in prospective development within the Central Highlands,” said Alcoa’s Reitan.

“Combining Vinacomin’s local knowledge and proven capacity for successful development of Vietnam’s mineral resources with Alcoa’s world-best alumina refining technology, operating practices, and sustainable development philosophy, and our firm commitment to education, training, and recruitment of local employees, creates an exceptionally strong partnership, capable of serving the interests of the Vietnamese people and those of Alcoa for generations to come,” Reitan added.

AWAC and Vinacomin will now embark on detailed studies with a view to completing definitive costs and definitive investment agreements as quickly as possible.

Alcoa is the world leader in the production and management of primary aluminum, fabricated aluminum and alumina combined, through its active and growing participation in all major aspects of the industry. Alcoa serves the aerospace, automotive, packaging, building and construction, commercial transportation and industrial markets, bringing design, engineering, production and other capabilities of Alcoa’s businesses to customers. In addition to aluminum products and components including flat-rolled products, hard alloy extrusions, and forgings, Alcoa also markets Alcoa^® wheels, fastening systems, precision and investment castings, and building systems. The Company has 97,000 employees in 34 countries and has been named one of the top most sustainable corporations in the world at the World Economic Forum in Davos, Switzerland.

Public Announcement 2008 – 31AWC

Alumina Limited previously advised on 11 June 2008 the financial impact to Alumina Limited’s underlying earnings for June 2008 arising from the shutdown of the Varanus Island gas supplies, was estimated to be A$12-17 million (after tax). The Company now confirms that the actual impact from the gas supply disruption on underlying earnings for June 2008 was A$7 million (after tax).

The impact for Alumina Limited’s underlying earnings for the third quarter of 2008 is now estimated to be A$31 million after tax. This estimate is dependent on gas supplies being restored by mid August 2008 and excludes a future insurance reimbursement for the increased costs and lost revenues. Alcoa World Alumina & Chemicals is working with its insurers to determine the recoverable amounts for the increased costs and lost revenues, and will net these reimbursements against any costs in future quarters.

Alumina Limited’s 2008 half year results will be released on 31 July.

For media enquiries, please contact Ken Dean on 0400 131 937.

Public Announcement 2008 – 32AWC

Alumina Limited today announced Alcoa World Alumina and Chemicals’ ( AWAC ) revision to the current estimate for the AWAC Joint Venture’s investment in the expansion of the Alumar alumina refinery at Sao Luis, and development of the AWAC bauxite mine at Juruti, both in Brazil. Alumina Limited has a 40% interest in AWAC.

Alumar Refinery

AWAC has a 54% interest in the 2.1 million tonne per year (mtpy) expansion of the Alumar refinery which will increase the refinery’s total capacity to approximately 3.5 mtpy.

The estimated cost of AWAC’s 54% investment in the expansion of the refinery is expected to increase from the USD 1.3 billion previously advised in January 2008 to USD 1.62 billion, reflecting the continuing appreciation of the Brazilian Real against the US Dollar, price pressures and additional materials and contractor costs. The Alumar refinery expansion is expected to reach mechanical completion by mid 2009.

The Alumar refinery is expected, on the completion of the expansion, to be a very competitive world scale alumina refinery.

Juruti Bauxite Mine

The cost of the Juruti bauxite mine development is expected to increase from USD 1.2 billion estimated in January 2008. It is now estimated to be approximately USD 2 billion with first shipment of bauxite expected in Q3 2009.

The increase is primarily a result of a delay in the construction schedule due to unseasonal wet weather and low contractor productivity, the appreciation of the Brazilian Real and increased infrastructure costs. Major projects in Brazil are experiencing substantial increases in construction and labour costs.

Juruti is a long life, high quality bauxite deposit, and the mine will initially supply 2.6 mtpy of bauxite for AWAC’s needs at the Alumar expansion. It will provide a strategic addition to AWAC’s long term bauxite resource base.

Mr John Bevan, Alumina Limited CEO, said: “ We are very disappointed with the increases in estimated cost of these projects to a total AWAC share of up to USD 3.7 billion. However these projects represent investment in long life strategic assets which are important for the long term growth of AWAC.”

The Company has committed undrawn debt facilities of approximately USD 400 million and will review during the second half of 2008 the most appropriate form for funding its share of this increased capital expenditure. When evaluating funding options, the Company intends to ensure it retains a conservative financial structure.

Alumina Limited will announce its financial results for the 6 months to 30 June 2008 on 31 July 2008. Alumina Limited expects underlying earnings for the half year to 30 June 2008 to be consistent pro-rata with a full year underlying earnings result based on previous guidance.

The Company’s Underlying Earnings are calculated as net profit after tax before the impact of certain non-cash accounting entries not related to the year’s operating performance. These non-cash entries relate to mark-to-market valuations of AWAC embedded derivatives, which reflect future aluminium prices based on the forward market at the end of the period, and certain employee benefit obligations.

For media enquiries, please contact Ken Dean on (03) 8699 2603 or 0400 131 937.
