capacity of ingot, slab and billet of 740,000 mtpy; and a rolling mill with initial capacity of 380,000 mtpy. The mill
will produce sheet, end and tab stock for the manufacture of aluminum cans, as well as other products to serve the
automotive, construction, and other industries.
The refinery, smelter and rolling mill are located within the Ras Al Khair industrial zone on the east coast of the
Kingdom of Saudi Arabia. First hot metal from the smelter was produced on December 12, 2012. The smelter reached
production of 190,000 mtpy in 2013 and is expected to reach full capacity in 2014. The first hot coil from the rolling
mill was produced in the fourth quarter of 2013 and the first automotive coil is expected in the fourth quarter of 2014.
First production from the mine and refinery is expected in 2014.
Total capital investment is expected to be approximately $10.8 billion (SAR 40.5 billion). Ma’aden owns a 74.9% interest
in the joint venture. Alcoa owns a 25.1% interest in the smelter and rolling mill, with the AWAC group holding a 25.1%
interest in the mine and refinery. For additional information regarding the joint venture, see the Equity Investments section
