Alcoa Update to Smelter Ramp-up at Ma’aden-Alcoa Joint Venture

October 16, 2013

Alcoa (NYSE: AA) today announced that the smelter at the Ma’aden-Alcoa
joint venture, which remains in initial start-up phase, has halted
production on one of two potlines.

The temporary shutdown was undertaken after a period of pot instability.
The joint venture is actively working to restore the potline, and it is
expected to be completed and back online between the first and second
quarter of 2014.

The ramp-up of the second potline was ongoing and will now be
accelerated.

There is not expected to be any impact to Alcoa’s customers.

There is no impact to any other part of the joint venture project,
including the mine, refinery and rolling mill, which all remain on
schedule.

About the Ma’aden Alcoa joint venture

In its initial phases, the joint venture will develop a fully integrated
industrial complex which will become the world’s preeminent and
lowest-cost producer of primary aluminum, alumina and aluminum products,
with access to the growing markets of the Middle East and beyond. The
complex comprises:

  • A bauxite mine with an initial capacity of 4,000,000 metric tons per
    year
  • An alumina refinery with an initial capacity of 1,800,000 metric tons
    per year
  • An aluminum smelter with an initial capacity of 740,000 metric tons
    per year
  • A rolling mill with initial capacity of 380,000 metric tonnes per year.

It will be the first in the Middle East capable of producing food grade
can sheet, as well as sheet for automotive, building and construction
applications. Upon completion, the mill will be one of the most
technically-advanced mills in the world.
