Avalon Signs MOU with Metso, a World Leader

in Critical Minerals Technology, to Advance

the Development of Ontario's First Lithium

Processing Facility

Toronto, Ontario--(Newsfile Corp. - July 10, 2023) - Consistent with its strategy to become a leading

North American vertically integrated lithium producer,

Avalon Advanced Materials Inc.

(TSX: AVL)

(OTCQB: AVLNF) ("Avalon" or the "Company") is pleased to announce it has signed a memorandum of

understanding to create a strategic partnership with

Metso Corporation

("Metso"), a global leader in

clean, sustainable critical-mineral processing technology.

The agreement, signed at Canada House in London UK, will immediately see the parties seek to

establish terms to develop a lithium hydroxide production facility to process lithium mineral concentrates

that are essential for the North American electric vehicle (EV) battery value chain.

Avalon intends to deploy Metso's world-leading technology to construct and operationalize a full-service

lithium processing facility at the Company's recently acquired Thunder Bay, ON. industrial site. Upon

completion of the project, Avalon will be the first vertically integrated lithium producer in Ontario, while

ensuring Canada's EV battery manufacturing base has a stable, proximate and long-term supply of this

strategically vital resource.

"Metso's platform and technological solutions perfectly complement Avalon's vision to complete an

integrated lithium value chain in Ontario, predicated on innovative process solutions," said Zeeshan

Syed, President of Avalon. "We view Metso as an integral part of this rapidly growing sector, and a

foundational partner in developing internationally best-in-class processing capabilities that are

environmentally sustainable, allowing Avalon to meet the soaring demand for battery-grade lithium."

The Non-Binding Memorandum of Understanding stipulates:

The pursuit of a definitive agreement to establish a lithium hydroxide processing facility in Thunder

Bay, Ont.

Avalon to license Metso technology and solutions to produce lithium hydroxide cathode materials

to serve the EV market.

Allow Metso to conduct testing and engineering work across Avalon's portfolio of critical-mineral

projects, including the Company's flagship deposit at Separation Rapids near Kenora, ON.

The parties anticipate reaching a definitive agreement on or before Sept. 1, 2023.

Metso's sustainable next-generation production and processing technologies are being deployed

internationally by governments and clean-energy producers in order to address and deliver the

necessary supply required by the emerging EV battery industry. Avalon's strategic partnership with

Metso is a first in Canada, and is a significant step towards helping the Company execute on its

vertically-integrated business strategy-and in turn, entrench Ontario's position as an advanced

manufacturing hub serving not only North America, but the world.

"Metso is looking forward to partnering with Avalon and be part of its long-term vision to be a mid-stream

supplier in the lithium hydroxide space. We are aligned with Avalon's vision of the future and proud to

play a key role in technology supply and advancement into clean energy solutions," said Mikko

Rantaharju, Head of Hydrometallurgy at Metso. "We are also extremely excited to be partnering with the

first Ontario conversion facility with Metso's technology. The innovation advantages of the alkaline

process allow for elimination of the use of potentially harmful chemicals such as sulfuric acid and

comparatively reduces overall solid waste and emissions, making it environmentally friendlier and

overall, safer for workers and local surrounding communities."

Canada's Critical Minerals Strategy

This partnership complements Avalon's strategic business objectives, while also providing direct support

to the federal government's Critical Minerals Strategy to increase the supply of responsibly sourced

critical minerals and develop domestic supply chains for the green and digital economy, as announced

by Natural Resources Minister, the Honourable Jonathan Wilkinson, as well as the Honourable Francois-

Phillippe Champagne, Minister of Innovation, Science and Industry.

The planned Thunder Bay processing facility and upstream lithium project in the Kenora region will

create an estimated 500 jobs. It will also enable broader development of northwestern Ontario's regional

lithium assets by other producers seeking to utilize the proximity of Avalon's processing capacity. The

facility will also help foster new economic development opportunities for local and regional First Nations

communities.

"We're honoured to play a role in securing Canada's clean-energy future, and understand the important

work that's still required across both the public and private sectors to deliver on the Province of Ontario

and Ottawa's stated goals," Mr. Syed added.
