Timminco and CaliSolar Jointly Announce Solar Grade Silicon Supply Agreement

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, Becancour 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. Rene 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 announce 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.
