Milestone marks commencement of fully integrated operations from mine to metal at Ma’aden Aluminium
      The Saudi Arabian Mining Company (Ma’aden) and lightweight metals leader
      Alcoa (NYSE:AA) today announced that the alumina refinery at their joint
      venture aluminum complex in Saudi Arabia has successfully produced its
      first alumina from Saudi Arabian bauxite. The alumina refinery at Ras Al
      Khair is the first ever refinery to be constructed and operated in the
      region.
    
      The milestone marks the commencement of the final link in the supply
      chain of this fully integrated aluminum facility. The alumina refinery
      will refine Saudi Arabian bauxite, supplied from Ma’aden Aluminium’s
      mine at Al Ba’itha and transported by 600 km rail to Ras Al Khair. The
      alumina from this refinery will feed into the Ma’aden Aluminium Smelter
      which produces the aluminum needed for the Ma’aden Aluminium Rolling
      Mill. This fully integrated chain delivers operational efficiency and
      creates the most competitive aluminum complex in the world.
    
      Once fully operational the refinery will produce 1.8 million mtpy of
      alumina. The alumina will be transported by conveyor to the adjacent
      smelter to produce 740,000 mtpy of high quality aluminum products for
      customers in the Gulf region and in international markets.
    
      “We are building a minerals and metals industry in Saudi Arabia that
      maximizes the value of the nation’s mineral resources; contributes to
      sustainable economic diversification and shareholder value; provides
      high value job opportunities for Saudis and a reliable supply of quality
      products to our global customers. This milestone marks a significant
      moment for our industry in Saudi Arabia and the broader GCC region,”
      said Khalid Mudaifer, President and CEO of Ma’aden.
    
      “As the lowest cost aluminum complex in the world, the Ma’aden Alcoa
      joint venture is an important plank of Alcoa’s strategy to create a
      globally competitive commodity business,” said Klaus Kleinfeld, Alcoa
      Chairman and Chief Executive Officer. “The first alumina milestone is
      another demonstration of our disciplined execution as we transform Alcoa
      to create sustainable shareholder value.”
