Avalon Files Quarterly Financial Statements and Provides Progress Report on Current Work Programs

19 July 2021

Toronto, Ontario--(Newsfile Corp. - July 19, 2021) - Avalon Advanced Materials Inc. (TSX: AVL) (OTCQB: AVLNF) ("Avalon" or the "Company") has filed its Quarterly Financial Statements along with the Management Discussion and Analysis for the period ended on May 31, 2021, which are now available on-line.

Management is pleased to report that the Company continues to make steady progress on all of its active projects. Following the closing of the recent flow-through financing, an exploration work program was initiated in June on its 100% owned Lilypad Cesium-Tantalum Project involving re-establishing a field camp and new grid on the property in preparation for detailed mapping and geochemical sampling to commence later this month. Additional cesium mineralized rock was collected from the Pollucite Dyke for continued process research on techniques to efficiently concentrate the rare cesium mineral pollucite, which continues to be in high demand. Drilling is planned for later this year.

On the Separation Rapids Lithium Project, processing of the bulk sample collected earlier this year has not yet commenced due to a lack of availability of suitably-equipped process facilities. However, the Company is now looking at several options for purchasing a demonstration scale Dense Media Separation ("DMS") plant that can be set up near the site to begin producing petalite product samples for the glass-ceramic companies that have expressed strong interest in the product. The Company intends to make the decision on the DMS purchase within the next few weeks.
