Avalon Reports on Separation Rapids Lithium

Project Progress as Lithium Prices Continue

to Rise

Toronto, Ontario--(Newsfile Corp. - May 10, 2021) -

Avalon Advanced Materials Inc.

(TSX: AVL)

(OTCQB: AVLNF) ("Avalon" or the "Company") is pleased to provide an update on recent developments

on its 100% owned Separation Rapids Lithium Project located near Kenora, ON and on lithium markets

generally. As recently reported by Benchmark Minerals Intelligence, Lithium prices are continuing to rise

in China, with both technical and battery-grade carbonate prices having doubled year-to-date. The price

of technical grade lithium carbonate was up 114.3% and battery-grade material was up 103.4% since

the start of 2021 with technical grade selling at US$12,700/tonne and battery-grade at $13,625/tonne.

With the overall lithium market expected to be in deficit, industry sources were predicting prices to rise

above $15,300/tonne in 2021, according to Benchmark.

To accelerate its lithium battery materials market development work, Avalon recently retained the

services of Mr. Joseph Plut as its new Director, Sales and Marketing. Mr. Plut has over 40 years of

experience in sales and marketing and most recently served as Sales Director for Nemaska Lithium,

where he was responsible for generating sales of their lithium hydroxide battery material product and is

now very knowledgeable in these markets. With the Company now progressing its plans to establish a

lithium battery materials refinery in Thunder Bay, ON, in collaboration with Rock Tech Lithium Inc., there

is considerable market interest in a new North American supply source, particularly in Europe and Asia.

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

February 1,

2021

was completed in mid-April and the 5,000 tonne sample is now in temporary storage in Kenora

before commencing crushing and shipping for processing. The bulk sample will be used to finalize the

process flow sheets for the lithium hydroxide product and for making petalite product samples for glass-

ceramic industry customers that have expressed interest. Potential markets for the by-products of

feldspar, high purity silica and aluminium silicate will also be explored.

Recent process testwork using dense media separation ("DMS") technology has proven successful at

producing a high quality petalite lithium mineral concentrate (4.0% - 4.2% Li

2

O) that can efficiently meet

the needs of specialty glass-ceramic end-users. The absence of froth flotation in the production process

results in a clean petalite product that is free of chemical residues. The next step is to produce larger

samples of this product for confirmation of its utility by glass-ceramic customers that have recently

expressed interest. With relatively few service providers having the scale of DMS equipment to efficiently

process larger bulk samples, the Company is now looking at acquiring its own DMS equipment so it can

more quickly meet the needs of the many end-users that have expressed interest over the years in

petalite product samples.

The Company is also now planning to resume exploration work this summer on the western part of the

Separation Rapids property where there are several other known lithium pegmatite occurrences that

have never been drilled and potential for further discoveries. The plan is to define a number of drill

targets to prepare for a drilling program in the fall. This will include drilling the new Snowbank petalite

pegmatite discovered in 2018, that is highly enriched in coarse grained petalite assaying up to 2.51%

Li

2

O in a 1.1m channel sample. This pegmatite has excellent potential to become a second source of

petalite to serve end-users in the glass-ceramic market.

The technical information included in this news release has been reviewed and approved by the

Company's President, Donald S. Bubar, P.Geo., and Dave Marsh, FAusIMM (CP), Consulting

Metallurgist, both Qualified Persons under NI 43-101.
