Avalon Advanced Materials Inc. announced that it has secured a firm commitment to purchase petalite concentrates produced at the Company's Separation Rapids Lithium Project north of Kenora, Ontario. The off-take agreement is for a multiple number of years with a majornon-Chinese international glass ceramic manufacturer. The agreement is subject to a number of conditions precedent, including the delivery and acceptance of a larger commercial sample of thepetalite product.

The customer has agreed to initially pay the current market price for the petalite product for at least the first year after commercial shipment commences. There is now considerable interest from other major glass ceramic manufacturers in Europe and Asia as there is presently a global shortage of petalite supply after China took control of the traditional petalite supply sources in Zimbabwe. Avalon's Separation Rapids Project hosts one of the few significant resources of the rare high purity lithium aluminum silicate mineral, petalite (LiAlSi4O10) in the world.

Next steps involve processing the5,000 tonne bulk sample collected from the project site in 2021 to produce trial quantities of the petalite product for the many end-users that have expressed interest. While the Company has been planning to establish a DMS processing facility on the property to begin producing trial quantities of the petalite product, Avalon now has access to an alternative process facility that will allow the Company to accelerate the process work to create the larger product samples this year that have been requested by the off-taker and the other glass-ceramic manufacturers that have expressed interest.
