Outlook for Aluminium

John Marlay, CEO, Alumina Limited 22 August 2007

THE MELBOURNEMINING CLUB

ALUMINA

LIMITED

Aluminium Industry Dynamics

Rapid growth in global consumption

China – self sufficiency accelerating

Brazil, India, Russia – consumption growing

New capacity growth – capital cost escalation

Energy – higher long term costs, plus carbon

Alumina and aluminium cost curves have moved up

Outlook for long term prices

Bauxite supply capacity – now stretched

Industry consolidation – continuing

ALUMINA

LIMITED

Aluminium Industry Dynamics

The massive escalation in prices, as well as costs of building new capacity, has rendered previous assumptions about long run prices embarrassingly redundant. The mining industry (and the investment banking community) is floundering with respect to what the appropriate basis to forecast long run prices should be

Jamalco Refinery Remains Closed; Assessing Damage From Hurricane Dean; Company Declares Force Majeure

NEW YORK—(BUSINESS WIRE)—Alcoa (NYSE:AA) announced today that production at the 1.4 million metric ton Jamalco alumina refinery in Clarendon, Jamaica remains halted while the company assesses damage caused by Hurricane Dean. Alcoa temporarily curtailed production at the refinery last Saturday as a safety measure in advance of the hurricane.

Preliminary reports indicate that the port from which Jamalco ships alumina did sustain substantial damage in the storm. The bauxite mine and refinery suffered less damage, but are not operational due to loss of power. A more complete assessment of the damages and the duration of the stoppage are being conducted.

In light of the temporary shutdown of the facility, damage to the port, and likely resulting delays in shipments, the company has declared force majeure to its customers.

Re-start schedule, production lost and financial impact will be reported after a comprehensive assessment can be safely concluded.

Jamalco is 55 percent owned by Alcoa World Alumina and Chemicals and 45 percent owned by the Government of Jamaica. Alcoa World Alumina and Chemicals is a global alliance between Alcoa and Alumina Ltd., with Alcoa holding 60 percent.
