Amsterdam, 16 June 2008 --- AMG Advanced Metallurgical Group N.V.
("AMG", EURONEXT AMSTERDAM: "AMG") announced that its 50.5%
subsidiary Timminco Limited ("Timminco"; TSX: TIM) and CaliSolar,
Inc., a privately held business based in Sunnyvale, CA ("CaliSolar"),
today jointly announced that Timminco's wholly-owned subsidiary,
Bécancour Silicon Inc. ("BSI"), has signed an agreement to supply
solar grade silicon, or upgraded metallurgical silicon ("UMG Si"), to
CaliSolar. The agreement provides for shipments of approximately
1,700 metric tons through December 2012. Initial shipments will
begin in the third quarter of 2008.

"CaliSolar, using BSI's UMG Si, has made a major breakthrough in
photovoltaic (PV) technology," said Dr. Eicke Weber, a CaliSolar
founder and Director of the Fraunhofer Institute for Solar Energy
Systems ISE in Freiburg, Germany. "The impact of UMG Si in this
important, rapidly expanding market can hardly be overstated. By
2015, half of the world's PV production could be based on the use of
UMG Si."

"In their search for a solar grade silicon supplier, CaliSolar has
done extensive tests with materials from many UMG Si producers and
obtained cell efficiencies over 15% with our product." said Mr. René
Boisvert, President and CEO of BSI. "This agreement to supply
CaliSolar is consistent with our strategy of supplying solar grade
silicon to companies with the capability to produce solar cells with
our material with efficiencies similar to cells produced with
polysilicon."

"When CaliSolar was founded two years ago, the mission of the company
was to develop specific technologies to make highly efficient solar
cells using 100% UMG Si," said Roy Johnson, CEO of CaliSolar. "This
contract with BSI allows CaliSolar to introduce a very competitive
product during the third quarter of this year."

"We are thrilled to this expansion of our relationship with Becancour
and look forward to continuing to work together to build a very large
UMG Si industry," said Dr. Kamel Ounadjela, COO of CaliSolar.

has two operating divisions of businesses, Advanced Materials and
Engineering Systems, and owns a majority interest in publicly-listed
Timminco Limited (TSX: "TIM").

The Advanced Materials Division develops and produces niche specialty
metals and complex metals products, many of which are used in
demanding, safety-critical, high-stress environments. AMG is one of
a limited number of significant producers globally of niche specialty
metals, such as ferrovanadium, ferronickel-molybdenum, aluminum
master alloys and additives, chromium metal and ferrotitanium, used
by steel, aluminum, chemical and superalloy producers for aerospace,
automotive, energy, electronics, optics, chemicals, construction and
other applications. Other key products produced by AMG include
specialty alloys for titanium and superalloys, coating materials,
tantalum and niobium oxides, vanadium chemicals and antimony
trioxide.

The Engineering Systems Division designs, engineers and produces
advanced vacuum furnace systems and operates vacuum heat treatment
facilities. AMG is a global leader in supplying
technologically-advanced vacuum furnace systems to customers in the
aerospace, energy (including solar and nuclear), transportation,
electronics, superalloys and specialty steel industries. Examples of
furnace systems produced by AMG include vacuum remelting, solar
silicon melting and crystallization, vacuum induction melting, vacuum
heat treatment and high pressure gas quenching, vacuum precision
casting, turbine blade coating and sintering. AMG also provides
vacuum case-hardening heat treatment services on a tolling basis to
customers through facilities equipped with vacuum heat treatment
furnaces.

Timminco Limited is a majority controlled, publicly-listed subsidiary
of AMG. Timminco is a leader in the production of upgraded
metallurgical silicon for the rapidly growing solar photovoltaic
energy industry. Timminco also produces silicon metal and magnesium
products for use in a broad range of industrial applications.

AMG operates globally with production facilities in Germany, the
United Kingdom, France, the United States, Canada, Mexico, Brazil and
Australia and also has sales and customer service offices in Belgium,
Russia, China and Japan (website: www.amg-nv.com).
