NEWS RELEASE

Avalon Publishes Ninth Annual Sustainability Report

Toronto, ON - Avalon Advanced Materials Inc. **** (TSX: AVL and OTCQB: AVLNF) ("Avalon" or "the Company") is pleased to announce that the Company has released its ninth annual comprehensive sustainability report, along with its 2020 annual filings including the audited financial statements. The Company also reports that its recent news release on the the signing of a Letter of Intent with Rock Tech Lithium Inc. generated considerable media coverage for which links are provided below.

The 2020 Sustainability Report focuses on health and safety, social, environmental and economic matters that are material to Avalon. The report was prepared in accordance with the Global Reporting Initiative Standards, core option. It includes a self-assessment of the Company's 2020 fiscal year sustainability performance and sets targets for 2021 against the Mining Association of Canada's Toward Sustainable Mining indicators.

In 2019, Avalon began integrating the United Nations' 17 Sustainable Development Goals ("SDGs") into its sustainability reporting. 17 SDGs were set by the United Nations in 2015 and are the world's shared plan to end extreme poverty, reduce inequality and protect the planet by 2030. Avalon has aligned its sustainability progress and goals with the SDGs to measure and manage its contributions towards these global goals.

Comments Avalon President and CEO, Don Bubar, "Avalon is very much on the forefront of sustainable best practices in mineral development, with a strong track record and a forward-thinking management team that makes sustainability a priority. For some time, Avalon has envisioned the opportunities that sustainable development of critical minerals supply chains offer Canada, but getting these types of projects started has been very challenging. However, our time has now come, with the recent recognition that the transition to a low carbon future cannot happen without adequate supply chains of the many critical minerals needed in clean technologies."

Avalon's 2020 Sustainability Report is available from the Company's website at http://www.avalonadvancedmaterials.com/sustainability/2020-sustainability-report.

The Company has also completed the filings of its 2020 Consolidated Financial Statements, Management's Discussion and Analysis and Annual Information Form with Canadian security regulators, as well as its Annual Report on Form 20-F with the U.S. Securities and Exchange Commission for the Company's fiscal year ended August 31, 2020. Copies of these filings are available through SEDAR at http://www.sedar.com; through EDGAR at http://www.sec.gov; or on the Company's website at http://www.avalonadvancedmaterials.com/investors/regulatory_filings.
