Orbite Releases Positive Preliminary Economic Assessment for Its Planned Metallurgical Grade Alumina Plant With the Capacity to Extract Value-Added Oxides, Rare Metals and Rare Earth Oxides

MONTREAL, QUEBEC--(Marketwire - Nov. 29, 2011) - Orbite Aluminae Inc. (TSX:ORT) ("Orbite") is pleased to announce the results of the Preliminary Economic Assessment ("PEA") prepared by Genivar Inc. on its planned commercial metallurgical grade alumina (SGA) production plant (the "Plant"). Orbite plans to produce an estimated 539,700 tonnes per year of alumina, 189,000 tonnes of pure hematite, 1.2 million tonnes of high purity silica, 28,000 tonnes of magnesium oxides, 104,000 tonnes of other value-added oxides, and 820 tonnes of rare metal and rare earth oxides, including, among others, dysprosium, erbium, europium, yttrium, cerium, neodymium, praseodymium, and terbium, and rare metals such as gallium and scandium.

All figures are in Canadian dollars except where noted.

Highlights

• Indicated resource of approximately 1 billion metric tonnes of homogeneous aluminous clay (23.13% average concentration alumina) as per NI 43-101.
• Based on conservative metal oxides selling prices (August 2011) and a 5% discount rate, the PEA reveals a pre-tax net present value (NPV) of $7.7 billion, generating an internal rate of return ("IRR") of 114% and a payback of under one year.
• Average production cost:
  • $44.53 / tonne of clay for all foreseen products;
  • $42.71 / tonne of clay for alumina and hematite alone.
• Feasibility Study underway with contract awarded to Genivar Inc. and expected to be completed during the first half of 2012, with planned commissioning in late 2013.

"The operations outlined in this PEA for Orbite's metallurgical grade alumina plant forecasted for initial production through the end of 2013 confirms the potential for high-value, low net production cost alumina and other value-added products. The projected high NPV, net cash flows, and relatively low unit cost compared to standard existing alumina processes provide strategic positioning for Orbite and its planned SGA production plant," said Richard Boudreault, Orbite's President and CEO. "Aluminum is the second most used metal after iron. We are therefore establishing the basis of our unique alumina extraction process and paving the way for the production of metallurgical alumina to meet growing demand from the global aluminium industry. This PEA also explains the net advantages of using an eco-friendly process while extracting high purity value-added products.

"We are pleased with the level of expertise and rigor of all of the parties involved in the Preliminary Economic Assessment of the planned metallurgical alumina production plant," continued Mr. Boudreault. "The exercise has also provided us with considerable insight into potential opportunities for further improvement of the already attractive economics. These include adapting existing technologies (i.e. calcination and acid recovery) and finding new ways to extract high purity products in addition to the alumina, while gaining considerable energy efficiency and thus greatly simplifying the process flow sheet. These opportunities will be validated during the Feasibility Study phase, which is ongoing at Genivar. The relatively low operating unit cost of production coupled with a much lower capital cost requirement than standard alumina greenfield projects using existing processes mean that this operation has the potential to be highly profitable in rapid time due to our unique alumina extraction process."

The table below summarizes the highlights of the PEA (all currency is CAN$, pre-tax):

NPV at 5% discount rate	$7.7 billion
IRR	114%
Total Estimated CAPEX	$498.5 million
Estimated OPEX (All products): (Alumina and hematite):	$44.53/t of clay $42.71/t of clay
Average annual EBITDA	$571.7 million
Estimated open pit mine life at present estimated production rate (Reference for one plant)	> 100 years
In-pit indicated resources (at 23.13% Al2O3):	> 800 M - 1 billion tonnes
Revenues to be generated by	2013-2014
Payback	11.0 months

"We are impressed by Orbite's visionary process, which is capable of refining alumina while at the same time extracting other high purity oxides, silica and hematite as well as certain high-value rare elements and metals from a local Gaspesian source of clay," said André-Martin Bouchard, Eng., Vice President at Genivar. "In addition, the process deploys technologies that will ensure that the local environment will be preserved, compared to current alumina refining processes, thus ensuring the sustainable development of the Gaspé region. We have also looked at the economics of producing and marketing only alumina and hematite, to validate the robustness of the project. In this case, the IRR was 33%, with an NPV of 1.7 B$ and a payback of 3.1 years at a 5% discount rate, demonstrating a strong business case."

Patented technology

Orbite owns the intellectual property rights to a unique Canada and U.S. patented process, a radical innovation aimed at extracting alumina from aluminous ores and for which international patents are also pending in many other countries, such as Brazil, Russia, Australia and Japan as well as in Europe. The patented Orbite process has the potential to become a viable alternative to the industry standard Bayer and other alumina processes, resulting in significant revenues when the technology is licensed to qualified alumina producers. Orbite is planning on marketing smelter grade alumina (SGA), high purity hematite, magnesium oxide, and silica, as well as producing rare earths oxides. Orbite also has several other patents pending related to various processes for producing such products.

Based on the chemical and metallurgical work completed at Orbite's production pilot plant facility and taking advantage of adaptable technologies for the acid recovery systems, the PEA estimated that the process is expected to yield an average of 93% weight recovery of Al₂O₃, higher than 90% on hematite, magnesium oxides, and high purity silica, and a conservative 75% for the extraction of rare earths, namely dysprosium, erbium, europium, yttrium, cerium, neodymium, praseodymium, and terbium, and rare metals such as gallium and scandium.

Details and assumptions

Total initial capital expenditures (including contingency) are estimated at $498.5 million to produce alumina and other value-added products. The initial capital cost estimate excludes mine closure costs and sustaining capital. Costs for mining equipment and all required infrastructures are included in the capital expenditure costs. The initial assessment of the preferred port facility suggests that sufficient capacity currently exists for the planned initial production. Energy supply represents one of the key elements of the Orbite project, as with all mining, chemical and hydrometallurgical projects. For the purpose of this study, electrical power and natural gas, which is known to be present but not readily available in the mining site vicinity, have been used as the reference energy source. The Henry Hub Index (September 2011) is used as the reference for natural gas prices. A $4.00/GJ has been used for the PEA evaluation.

CAPEX preliminary evaluation:
Summary of estimated initial capital costs	Million $
Mining, environmental, tailings	33.8
Major buildings and process equipment	335.0
Plant infrastructure	24.2
Other infrastructures	45.0
Contingency	60.5
TOTAL	498.5

Consistent with industry practices, this PEA has been prepared with an accuracy of +/-30%. As the project progresses through the ongoing feasibility stage, advancement in the basic engineering will improve the accuracy to approximately +/-15%.

The Feasibility Study scope of work involves a comprehensive review of all project characteristics-from process validation to capital costs, operational costs, and basic engineering leading to the detailed engineering, marketing, environmental, health & safety, and other considerations-in order to further validate and integrate the various technical aspects of the project. The Feasibility Study report is expected to be published during the first half of 2012.

About Orbite

Orbite owns 100% of the mining rights on approximately 6,441 hectares of a Grande-Vallée property, the site of an aluminous clay deposit located 23 km to the south of Grande-Vallée, and a 2 600 sq. m. full scale pilot plant in Cap Chat, in the Gaspé region. The NI 43-101 report issued in August 2011 has identified an Indicated Resource of about 1 Billion tonnes of aluminous clay in part of the deposit. The Company also owns the intellectual property rights to a unique Canada and U.S.-patented process for extracting alumina from aluminous ores and for which patents are also pending in other countries. www.orbitealuminae.com

The PEA is preliminary in nature and it includes Indicated mineral resources of aluminous clay that are considered too speculative geologically to have the economic considerations applied to them that would enable them to be categorized as mineral reserves. There is no certainty that the conclusions reached in the PEA will be realized. Mineral resources that are not mineral reserves do not have demonstrated economic viability.
