Avalon and Fort William First Nation Sign

Letter of Intent to Collaborate on Development

of Thunder Bay Lithium Refinery

Toronto, Ontario--(Newsfile Corp. - March 31, 2021) -

Avalon Advanced Materials Inc.

(TSX: AVL)

and (OTCQB: AVLND) ("Avalon") is pleased to announce it has entered into a Letter of Intent ("LOI") with

Fort William First Nation ("FWFN") to collaborate on the development of a lithium battery materials

refinery located on industrial lands owned by FWFN in Thunder Bay, Ontario. This facility would be

designed to accept lithium mineral concentrates from Avalon's Separation Rapids Lithium Project (70

km north of Kenora) and Rock Tech's Georgia Lake Lithium Project (145 km northeast of Thunder Bay),

as well as potentially other emerging, new lithium mining operations in northern Ontario, to produce

lithium hydroxide and other lithium battery materials.

Avalon and FWFN have determined the next steps would be as follows:

Identification of a specific location for the refinery on the waterfront with access to transportation

infrastructure, hydro-power and natural gas.

Conduct the necessary engineering, site preparation and construction design studies to prepare

for initiation of refinery construction in 2022, once all necessary permits and authorizations are in

place.

Finalize the initial design capacity facility of the refinery once firm off-take commitments have been

secured from interested battery manufacturers and design the facility to accommodate future

expansion as demand for the products increases. The anticipated initial design capacity will be to

produce at least 15,000 tonnes per year of lithium hydroxide and/or lithium carbonate as well as

lithium sulphate, the precursor chemical for making either the carbonate or hydroxide.

Secure the necessary capital required to proceed with construction in 2022.

Avalon's President and CEO, Don Bubar commented, "We are delighted to have the opportunity to

create a new precedent for collaboration with Indigenous Business toward establishing a lithium battery

materials supply chain in Northern Ontario. I share FWFN Chief Peter Collins' vision for how this

operation can inspire other Indigenous Businesses to become future suppliers of lithium mineral

concentrates for the refinery and how FWFN can become the Hub of the North for all First Nation

communities in Northwestern Ontario."

Separation Rapids Project Update

The bulk sampling program on Avalon's 100% owned Separation Rapids lithium deposit announced on

February 1, 2021

is progressing well with roughly 80% of the total 5,000 tonne sample having been

trucked to Kenora for temporary storage before crushing and shipping for processing. The balance of

the 5,000 tonnes is expcted to be trucked to Kenora over the next week, depending on weather

conditions. The bulk sample will be used to finalize the process flow sheets for both the lithium hydroxide

product and for making petalite product samples for glass-ceramic industry customers that have

expressed interest. Near term plans also include resuming exploration work on the western part of the

property for other lithium pegmatites including drilling the new Snowbank petalite pegmatite discovered

in 2018, that is highly enriched in petalite assaying up to 2.51% Li

2

O in a 1.1m channel sample.

Corporate Update: Filing of SEC Form 15F

In its continuing efforts to reduce financial reporting complexity and administrative costs, Avalon will

voluntarily file a Form 15F with the United States Securities and Exchange Commission (the "SEC")

today for the purpose of deregistering and terminating its reporting obligations under Section 13(a) and

Section 15(d) of the Securities Exchange Act of 1934, as amended (the "Exchange Act"), with respect to

its common shares.

The filing of Form 15F will immediately suspend the Company's reporting obligations under the

Exchange Act, and the deregistration will become effective 90 days from today.

The Company's shares

will continue to trade on the TSX and the OTCQB.

The Company will continue to comply with its

Canadian continuous disclosure obligations by continuing to make filings with the applicable Canadian

securities regulators, and which will continue to be available on SEDAR at

www.sedar.com
