Orbite Aluminae Inc. (TSX:ORT) ("Orbite" or the "Company") is proud to announce it produced its first commercial samples of high-purity alumina (HPA) at purity levels of 99.999% (5N). This achievement follows the production of 99.99% (4N) purity HPA that that the Company previously achieved in 2011 while the market is transitioning to higher purity levels. Consequently, Orbite continues to upgrade its technical capabilities to produce not only 4N and 5N HPA but also to achieve 99.9999% (6N) purity level. The 5N samples were pre-tested by independent laboratory Evans Analytical Group (EAG), which confirmed their compliance with the Company's and market purity specifications. These samples will shortly be sent to selected collaborators, designated based on their HPA needs, their intent to increase consumption of this type of alumina and the potential for strategic partnerships with the Company in regards to HPA marketing activities. To date, more than a dozen prospective clients have requests samples of high-purity alumina.

"The significant anticipated growth in HPA annual worldwide demand, which according to Mackie Research will rise from 9,000 tons in 2012 to over 15,000 tons in 2015, will lead to a substantial supply deficit of about 6,000 tonnes per year caused notably by the global increase of light emitting diodes (LED) demand. I'm very pleased that a large number of first-rate, internationally renowned companies are interested in our HPA and are prepared to evaluate our materials. The quality and purity of our alumina provides an opportunity for Orbite to fill a pressing and growing market need," stated Yves Noel, Vice President of Sales and Marketing at Orbite.

United States public listing

Orbite is pleased to announce its intention to pursue, in the coming months, the listing of its class A shares on the OTCQX, a U.S. based securities market. OTCQX is the premier tier of the over the counter market, and offers international companies a visible presence in the United States of America without the duplicative regulatory burdens of a traditional U.S. exchange listing. Orbite's planned application to the International OTCQX is by no means assured, and all required listing requirements must first be met before a listing may be granted. This listing would lead to an increased fluidity and a broader market for Orbite's shares.

Pursuant to its press release issued on June 26, 2012, the Company confirms that with its patented rare earth and rare metal extraction and separation process, and the collaboration of its two European partners, CMI-UVK and MEAB, it has established the process parameters and final design of the rare earth and rare metal separation technology, This work enabled the successful extraction and separation of commercial samples of other rare earth oxides and rare metals, such as neodymium, dysprosium (both 99.9% pure), cerium (99.5% pure), as well as gallium oxide (99.99% pure).

Neodymium and dysprosium are used in the manufacturing of permanent magnets, and both appear on the list of short and medium-term critical materials as a consequence for their significant importance for green energies and their high supply risk, as stated in the latest Critical Materials Strategy report issued by the U.S. Department of Energy in December 2011.

Gallium is widely used in the semiconductors industry, which in the past has relied heavily on silicon. Today, however, gallium arsenide is a semiconductor that is particularly sought after for the manufacturing of light emitting diodes (LED) and high electron mobility transistors considering its optical and electronic properties. Furthermore, gallium nitride's properties are particularly well suited for high power, high temperature and high frequency electronic applications.

Cerium, for its part, has extensive applications in the manufacturing of polishing products used in particular in the glass and electronics industries. Cerium is also used to make catalytic converters, which serve to reduce carbon monoxide emissions. Finally, the inclusion of cerium-based additives in diesel fosters a more efficient combustion, resulting in less air pollution.

Basic engineering phase for the smelter grade alumina plant over 90% completed

In addition, Orbite is updating the progression status of its smelter grade alumina (SGA) plant. The basic engineering was commissioned to international industry leaders, qualified to establish the foundation required for the next phase, namely detail engineering leading up to the construction of the SGA plant. To date, the basic engineering is 100% completed for the following sectors: ALP (semi-continuous acid leaching plant) by Johnston Vermette and Genivar; ACP (crystallization plant) by SMS Siemag; CP (calcination and associated acid recovery) by Outotec; HARP (hematite production and associated acid recovery) by SMS Siemag; MgO (magnesium oxide production and associated acid recovery) by CMI-UVK; alkali (alkali conversion and associated acid recovery) by CMI-UVK; and REEP (individual rare earths and rare metals extraction plant) by CMI-UVK. The acid purification unit, the clay crushing unit and the integration of sub-systems are on the verge of being completed. Overall, the SGA project basic engineering is more than 90% complete.

"The basic engineering was entrusted to international leaders qualified to establish the fundamental parameters for the construction of the smelter grade alumina plant," added Denis Primeau, Eng., MBA, Chief Engineer at Orbite. "The feasibility study is expected to enable the integration of these elements during the final phase by the end of 2012. The energy aspect is properly controlled; a usage matrix by combustible type has been implemented and covers all required parameters (cost, availability, specific energy, etc.) and provides a plurality of appealing energy options to Orbite. The Orbite project is and remains an entirely chemical and non-metallurgical based process, which considerably reduces complexity."

Accelerating time to market

In response to widespread interest in its technology and range of products, the Company has decided to invest in the production of commercial samples and its ability to conduct technical tests at its Laval facilities to assist in the production and commercialization of high-purity alumina (HPA). The size of its facilities has therefore doubled to accommodate new leading-edge equipment, including additional 20 and 50-litre reactors. In addition, a reduced-scale HPA production unit with a nominal 5 kg/hr output, precisely modelling the future HPA manufacturing process at Orbite's HPA plant, is being installed as part of this expansion.

"I am very pleased to confirm that our commercial samples are consistently meeting and indeed exceeding the specifications of our future potential customers," stated Dr. Hubert Dumont, Technical Director at Orbite. "We are already planning process improvements to enable us to attain the highest purity standards and offer a more extensive line of products."

This investment will enable the Company to increase its high end commercial sample production capacity and will support ongoing efforts at the Cap-Chat production plant by providing HPA and conduct tests and analyses in a shorter time frame. The initiative will also accelerate Orbite's commercialization of its HPA and therefore hasten the generation of positive cash flow.

Annual General Meeting

The Company will hold its annual and special shareholders' meeting today at 2:00 p.m., at the Courtyard Montreal Airport, 7000 Place Robert-Joncas, Montreal.
