Avalon Advanced Materials Inc. - AVL.t

Avalon Advanced Materials Inc. - AVL.t (formerly Avalon Rare Metals) is advancing the flagship Separation Rapids Lithium Project near Kenora, Ontario and the East Kemptville Tin-Indium Project in Yarmouth, Nova Scotia.

On April 5, 2016 the company released News

Avalon Advanced Materials Inc. 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 (www.avalonadvancedmaterials.com/news_media/display/index.php?id=17578)).
