Montreal, Quebec. – Orbite Aluminae Inc. (TSX:ORT) (the “Company”) is proud to announce that an independent analysis of samples of individual rare earth oxides (REO) and rare metal oxides (RMO) has confirmed a 23% increase in recovery rates over the figures published in the Revised Preliminary Economic Assessment Technical Report dated May 31, 2012, thereby increasing value of its smelter grade alumina (SGA) production project. Orbite also reanalyzed results of the various drilling campaigns carried out in recent years, confirming previously disclosed results.
Analysis of oxide extraction
The Company recently mandated European-based CMI-UVK GmbH to evaluate the extraction and separation of rare earth oxides and rare metal oxides from the Company’s Grande-Vallée deposit. The tests were independently carried out at MEAB’S pilot plant in Germany.
The recovery results of the pilot assays attest to the individual extraction rates of the following elements: Gallium (99.8% – pH-controlled), Scandium (99.0% – pH-controlled) and Yttrium (93.0% – pH-controlled). As such, and taking into account the 95% concentration factor obtained in the front end acid recovery portion of the extraction process and a calcination loss of less than 1%, the Orbite process is expected to generate the following overall minimum oxide yields: Gallium at 93.86%, Scandium at 93.11%, and Yttrium at 87.47%. This represents a 23% increase in recovery rate over the figures published in the Revised Preliminary Economic Assessment Technical Report (“Revised PEA”) dated May 31, 2012. Product samples representative of the final commercial phase are now available, and pilot phase assays for the other heavy elements (REO and RMO) are currently underway. The data obtained following the pilot assays has served as the basis for the design of the rare earths processing segment of the Company’s smelter grade alumina (SGA) production plant and are being incorporated into the feasibility study relating thereto.
“The success of Orbite’s technological innovation begins with its patented process. It has now been demonstrated that Gallium, Yttrium and particularly Scandium produced using the Orbite process should position the Company favourably in the market for these elements, with alumina remaining our principal product,” explained Richard Boudreault, President and CEO of Orbite.
“Given the positive results reported at the German pilot plant, we can now confirm that in addition to planning the overall recovery of acid and rare earths from the aluminous clay, the Orbite process shows major potential for the individual extraction of certain elements such as Scandium and other heavy rare earths as SGA by-products.”
Additional testing analyses confirm added value of oxides
As part of its program to evaluate rare earth oxides and rare metal oxides, the Company announces the results of REO and RMO concentrations in the drilling samples from its 2008 to 2010 drilling campaigns. Following the release of the Revised PEA, the Company conducted additional analyses of Grande-Vallée samples from previous drilling campaigns. The ensuing study focused on more than 1,088 analysis results from 34 drill holes covering an area of approximately 3,000 metres east-to-west and 1,200 metres north-to-south.
The results of this second analysis confirm and reinforce the conclusions of the Revised PEA and clearly indicate that the REO and RMO values will add economic value to the Company’s project, given the individual extraction and separation results obtained for heavy REO and RMO.
The results of this supplementary analysis are presented below:
For comparative purposes, the REO and RMO results published in Orbite’s April 18, 2012 press release, and obtained from the limited sampling of its 2011 drilling campaigns are reproduced below.
All of the values in the two tables above represent the arithmetic means of the analytical results for each clay and mudstone horizon. All analyses have been based on samples with concentrations higher than 18% Al2O3, i.e. the cut-off grade used in the evaluation of the resources in the Revised PEA. The samples were assayed according to the ME-MS81 protocols for rare earth elements and Ga and according to the ME-4ACD81 protocols for Sc at the ALS Minerals laboratory in Vancouver, British Columbia, with the detailed procedures available at www.alsglobal.com/minerals.aspx. In addition to the quality control program using duplicates and reference standards provided by the laboratory ALS Minerals, Orbite has adopted its own QA/QC program that adheres to best industry practices. Out of the samples analyzed, a 7.5% sub-group was randomly chosen and sent to a separate laboratory for comparative analysis. The results of this verification indicate that the average content of the total REO and RMO of the sub-group varies by less than 1% compared to the average REO and RMO content of all samples combined.
For all of the groups discussed, the percentage of heavy REO compared to the total REO (heavy REO/REO) varies from 21% to 22% for groups in the clay horizon and is 23.1% for those in the mudstone horizon. The heavy REO are defined by elements Eu, Gd, Tb, Dy, Ho, Er, Tm, Yb, Lu, and Y, without taking into consideration the 0.5% of Sc content.
A comparison between the average oxide values in the tables above show considerable similarities, further demonstrating the strong chemical homogeneity of the Grande-Vallée aluminous clay deposit. Whether part of the limited 2011 drilling campaigns in the Marin sector, the more widespread drilling campaigns conducted between 2008 and 2010, or the drilling samples from the Simoneau sector more than 13 km west of Marin, the total REO values and the RMO values are virtually identical.
The plotting of the combined REO values, the individual REO values, and the RMO values based on Al2O3 demonstrates the strong correlation of these oxides with the alumina values in both the clay and mudstone horizons. The single exception is Sc2O3, which reveals a consistent value in most samples without, however, correlating to the alumina values.
Strategic Elements Symposium
Orbite Aluminae, was invited to make a formal presentation on critical elements at the Strategic Elements Symposium in New York City on June 19, 2012. The event was hosted by Murdock Capital Partners, an American firm specializing in private banking services, and over sixty American institutional investors interested in strategic metals were in attendance. The keynote presentation from Jack Lifton, co-founder of Technology Metals Research, along with all other presentations, are available at www.murdockcapital.com .
Natural Resources Canada holds rare earths workshop
On June 26, 2012, Mr. Richard Boudreault, President and CEO of Orbite Aluminae, Dr. Joël Fournier, Chief Scientific Officer and Mr. Yves Noël, Vice-President, Business Development, Sales and Marketing, will participate in a one-day rare earths workshop in Ottawa held by Natural Resources Canada. Targeting research and development as well as polices surrounding rare earths and bringing together Canadian experts, employees of Natural Resources Canada, and representatives from the US, European and Japanese governments, the event will enable the Company to raise awareness about its potential to produce rare earths in the short-term from its Grande-Vallée resources.
