Orbite Confirms Choice Regarding Hydrothermal Process for its Green Smelter Grade Alumina Plant

MONTRÉAL, QUÉBEC--(Marketwire - April 10, 2012) - Orbite Aluminae Inc. ("Orbite" or the "Company") (TSX:ORT) confirms its choice for hydrochloric acid ("HCl") recovery technology for its smelter grade alumina ("SGA") plant operations based on data from SMS Siemag and ThyssenKrupp supporting the hydrothermal process efficiency and recovery rates. Part of the design of the SGA plant implies the recovery and the regeneration of hydrochloric acid. Key decision factors in selecting this technology include the high yield recovery of acid, economic viability, as well as environmental friendliness.

Orbite's engineers conducted a thorough technical due diligence of the technologies available including spray roasting, fluidized beds and hydrothermal process. The selection process included sites visits of such commercial scale operations.

As a result of the technical due diligence, the Company has selected the hydrothermal process from SMS Siemag as the technology of choice. This decision was based on the technology's ability to respond to large commercial scale requirements including high recovery yield, low energy consumption with regard to lower operating temperatures, product quality (HCl concentration and hematite quality) and very low atmosphere emissions.

"The Hydrothermal Acid Regeneration Plant at ThyssenKrupp Steel USA located in Calvert, Alabama is continuing its operations. SMS Siemag is pursuing the commissioning and utilization of the Hydrothermal Acid Regeneration Plant. Demonstration of energy consumption, recovery rates as well as product and by-product quality targets have already been achieved" said a senior executive at SMS Siemag Process Technologies GmbH.

"We have great confidence in the Hydrothermal Acid Regeneration technology for our planned SGA plant, as well as in SMS Siemag's expertise in that field. Our Chief Scientific and Chief Engineer performed a due diligence at the ThyssenKrupp Steel USA, and their conclusions reinforced our choice to choose the Hydrothermal Acid Regeneration technology rather than more conventional ones, and this, in order to achieve a clean technology and a low energy consumption Smelter Grade Alumina plant", said Richard Boudreault, President and CEO of Orbite Aluminae.

As planned, Orbite will be generating revenues by the end of 2012 and beyond with its High Purity Alumina Plant, while looking to licence its patented technologies. The first SGA plant is planned for the end of 2013 or beginning of 2014 with the active cooperation of Rusal, the world's largest aluminum producer.
