Gramercy, Louisiana – May 19, 2017 – Noranda is pleased to announce that it has approved more
than $35 million of capital improvements at its Gramercy, LA refinery, the majority of which is
designated for the expansion of its chemical grade alumina (CGA) production and increasing its capacity
to manage residual bauxite at the site. For its CGA expansion, Noranda will undertake the design and
installation of an additional hydrate filter, dryer, and related production, storage and shipping
infrastructure at the facility. That capital project is expected to increase Noranda’s annualized CGA
production by greater than 200,000 metric tons within the first half of 2018. Noranda will also
undertake the design, construction, and installation of two filter presses and related infrastructure that
are expected to be in full operation by the end of the first quarter of 2018. With the addition of this
state of the art filter press technology, Noranda will not only expand its capacity to store and effectively
manage its ongoing residual bauxite, but also will be able to significantly reduce the volume of its
existing residual bauxite lakes and extend the life of the facility. To assist Noranda with these
modernization and expansion projects, which are expected to add a large number of new jobs in
Gramercy, Louisiana Economic Development (LED) and the state of Louisiana is providing a package of
significant incentives and tax credits to the company.

David D'Addario, CEO of Noranda, commented, "These capital improvements represent the largest
capital expenditure at Gramercy in more than a decade. The projects will not only expand the
production capacity for our valued CGA customers and create new jobs for our community, they will
help ensure the continuation of this business and its 400 plus jobs by enabling us to operate more
efficiently and effectively and with even greater environmental responsibility. We are grateful to
Louisiana Economic Development and Governor Edwards for the confidence they have shown in the
success of our business as demonstrated by LED’s significant financial support.”

“This is a great opportunity to create new good-paying jobs and to secure hundreds of existing jobs at an
industrial mainstay in our River Parishes,” Gov. John Bel Edwards said. “Noranda’s new ownership team
is committed to the success of its business, and we are pleased to provide strategic assistance to their
efforts to modernize and expand their operation in Gramercy.”
