Avalon Completes Pilot Plant Processing of Bulk Sample from Separation Rapids Lithium Project, Kenora, Ontario

05.04.2016  |  GlobeNewswire

TORONTO, April 05, 2016 (GLOBE NEWSWIRE) -- Avalon Advanced Materials Inc. (TSX:AVL) and (OTCQX:AVLNF) (“Avalon” or the “Company”) is pleased to provide a progress report on process development work for its Separation Rapids Lithium Project, Kenora Ontario (the “Project”). Pilot processing of a bulk sample of the ore has successfully produced one tonne of high purity lithium mineral concentrate (petalite) that meets target specifications. Approximately 300kg will be used for further process development work toward defining a flowsheet for production of a high purity lithium chemical for battery applications. Preliminary work is already underway and scheduled for completion in June, 2016 with further piloting of the process planned for later in 2016. The remainder of the concentrate will be shipped to potential customers in the glass industry who have requested product samples for evaluation in glass-ceramic applications.

The bulk sample pilot plant was conducted at metallurgical facilities in Germany under the direction of Dorfner Anzaplan GmbH, Germany (“Anzaplan”), a specialist in industrial minerals process development. The flow sheet employs magnetic separation and froth flotation processes that are a significant improvement on the process originally developed and patented by Avalon in 1998-99 to produce a petalite concentrate for glass-ceramics. The concentrate produced meets customer expectations on lithium content and purity, assaying 4.0% Li2O and less than 0.01% Fe2O3. The work was supervised by Avalon’s Senior Vice President, Metallurgy and Technology Development, Mr. David Marsh.

The lithium chemical process development work will test a hydrometallurgical flowsheet conceived by Avalon for the production of battery grade lithium hydroxide, (the product now preferred by many battery manufacturers) directly from petalite. The proposed process results in efficient use of reagents through re-cycling and generates minimal waste material. The results from this work will be used to generate a Preliminary Economic Assessment (“PEA”) scheduled for completion this summer. The ability to produce battery grade lithium carbonate was previously demonstrated during initial testwork carried out in 2015 (See the Company’s News Release dated October 8, 2015).

Future Plans
The PEA is currently being compiled based on the resource as defined during the original drilling programs conducted by Avalon in 1997-2001. At currently anticipated production rates this would provide sufficient resources for a minimum 10 year operating life. The resource remains open to depth and along strike for expansion and a summer exploration drilling program is currently being planned to delineate additional lithium resources.

Following the completion of the PEA this summer, Avalon intends to proceed into a full feasibility study along with environmental assessment work with a target date for completion in Q2 2017.

In the meantime, the Company is studying alternatives for delivery of clean, low-cost power to the project site and alternative locations for the hydrometallurgical plant to produce the proposed lithium hydroxide product for the battery industry.

Potential By-Products
Because of the unique composition of the Project’s lithium ore, the deposit has the potential for recovery of several valuable by-products including high purity silica, feldspar and tantalum. Testwork at Anzaplan to define precise by-product specifications and the required process flowsheets to produce them is ongoing. By-product recovery has the potential to significantly increase revenues and decrease the amount of waste material produced.

Recent work has resulted in the discovery that a high quality silica product can be recovered from the petalite flotation tailings. Investigations are currently underway to determine the viability of upgrading such a product to potential semi-conductor applications, telecommunications and microelectronics, with a current market price in the range of US$4,000 to $8,000 per tonne. Results of these investigations are expected by late June.

Further, the feldspars in the ore, when finely ground, exhibits similar properties to nepheline syenite which is widely used as paint filler, a flux in the glass making industry, ceramic glazes and as an anti-block agent in clear waste disposal bags. Initial testwork has yielded a feldspar product that compares favourably to nepheline syenite products currently available in the market. Lastly, the magnetics fraction offers potential for further treatment to recover tantalum, niobium and additional lithium for the hydrometallurgical plant, which is also being investigated.

The technical information included in this news release has been reviewed and approved by the Company’s Senior Vice President, Metallurgy and Technology Development, Mr. David Marsh, FAusIMM (CP), who is a Qualified Person under NI 43-101.
