Avalon Announces the Commencement of

Feasibility Study at Lake Superior Lithium

Project, Ontario

Toronto, Ontario--(Newsfile Corp. - January 19, 2026) -

Avalon Advanced Materials Inc.

(TSX: AVL)

(OTCQB: AVLNF) ("

Avalon

" or the "

Company

") is pleased to announce the commencement of

Feasibility Study ("FS") engineering for its Lake Superior Lithium Inc. ("LSLi") lithium hydroxide

processing project in Thunder Bay, Ontario, Canada.

Following the successful completion of a Preliminary Economic Assessment ("PEA") in September

2024, Avalon has assembled a highly experienced and integrated engineering team to advance the

project through the FS phase. The contracting process included a comprehensive review of proposals

from multiple qualified firms, culminating in the selection of the most technically aligned and cost-

effective partners for the next stage of project development.

Nordmin Engineering Ltd. ("

Nordmin

") has been engaged as the lead FS consultant, responsible for the

overall project coordination as well as design of the processing plant and site infrastructure in

collaboration with Primero Americas Inc and Krech Ojard & Associates. Complementing Nordmin's role,

Avalon has retained

Metso Corporation,

which previously engaged during the PEA phase and is

already deeply familiar with the project's data and design basis.

Each discipline within the Feasibility Study will be overseen by Qualified Persons under NI 43-101,

ensuring technical continuity and regulatory rigor throughout the FS process. These firms were selected

following a rigorous evaluation and competitive review process, based on their demonstrated technical

excellence, team integration, and relevant experience on the Project. Together, they form a cohesive and

high-caliber engineering consortium with proven success delivering complex lithium projects.

"We are excited to move into the feasibility engineering phase for the Lake Superior Lithium, Project,"

stated Scott Monteith, President & CEO of Avalon. "The Feasibility Study builds on the technical and

commercial groundwork established in the PEA as the project advances toward partnership

engagement and financing readiness. With a strong technical foundation, a highly experienced and

capable in-house Owner's team and a solid funding position, Avalon is well-positioned to deliver the

Feasibility Study in the first half of 2027 and move decisively toward construction readiness. The LSLi

processing facility will position Avalon to play a key role in the emerging North American lithium supply

chain serving EV and energy-storage markets."

"Nordmin Engineering is very pleased to support Avalon in advancing the Feasibility Study for the LSLi

project," said Kurt Boyko, Director, Consulting Engineering of Nordmin Engineering. "This study

represents an important step in demonstrating the potential of a significant project at LSLi, and we're

proud to contribute our technical expertise to its development. We look forward to working closely with

Avalon's team to deliver a high-quality and comprehensive study."

North American electrification and energy-storage markets remain reliant on offshore lithium conversion

capacity, as commercial-scale refining of battery-grade lithium currently occurs largely outside of North

America. Avalon's decision to advance toward a feasibility study marks a meaningful step forward in

positioning LSLi as one of the first lithium refineries in Canada and a prospective contributor to a more

secure North American battery supply chain.

Notably, the feasibility study will include trade-off studies with a comprehensive evaluation of whether

battery-grade lithium hydroxide and/or lithium carbonate represents the optimal final product for the

facility, based on evolving market demand, customer qualification requirements, and downstream

engagement.

In October 2025 the Company closed a C$18.65 million financing and committed to advancing its core

rare earth and lithium assets through updating technical and economic studies. The initiation of a

Feasibility Study for its planned lithium refinery demonstrates the Company's execution on those

commitments, advancing project readiness and supporting ongoing strategic partnership and financing

discussions.

2024 PEA Demonstrated Strong Project Economics

The September 2024 PEA was prepared by DRA Americas Inc. and demonstrated the Project's

compelling economic viability. The PEA considered a design capacity for the annual production of

30,000 tonnes of battery-grade lithium hydroxide (LiOH).

All dollar values in this news release are expressed in Canadian Dollars unless indicated. (USD:CAD =

1.36)

Key Highlights of PEA include:

After-tax Net Present Value ("NPV") of $4.1 billion at 8% discount rate

After-tax Internal Rate of Return ("IRR") of 48% for the 30-year period

Initial Capital Cost $1.2 billion and Total Capital Cost $1.3 billion

All-in Life-of-Project Operating Costs of $13,029/tonne (includes spod. purchased)

Innovative Metso Technology provides an environmentally clean process over conventional lithium

hydroxide processes

Strategically located in historical industrial land with well-established infrastructure

The basis of the PEA is built on the utilization of the innovative Metso lithium hydroxide conversion

technology that is currently being tested. This technology allows for a clean zero-discharge process with

no acid roasting and the production of a by-product that can be used as an industrial building material.

LAKE SUPERIOR LITHIUM HYDROXIDE FACILITY OVERVIEW

Avalon Advanced Materials Inc. owns 100% of the property situated on the north shore of Lake Superior

approximately 13 km northeast of Thunder Bay, at 965 Strathcona Avenue. It was formerly a pulp and

paper facility last owned by Smurfit-Stone.

METSO PROCESS DESIGN

The plant will utilize Metso's proprietary technologies, which includes calcination, pressure leaching,

conversion, purification through ion exchange (IX), and crystallization before the drying and packaging

processes to ensure the production of high-quality lithium hydroxide monohydrate. Metso's technologies

will enable the creation of a compact, energy-efficient lithium hydroxide production plant with minimal

chemical usage, aiming to produce 30,000 tpa of battery-grade lithium hydroxide monohydrate (LHM).

Infrastructure

The Project benefits from having significant existing infrastructure, enabling accelerated development of

the project.

Roads

The property is accessed via Shipyard Road which intersects Strathcona Avenue. Strathcona Avenue is

linked to the Trans-Canada Highway (Highway 11 / 17) by Spruce River Road just East of the property.

Internal roads for the property will be developed to access all buildings for personnel movement and

commercial deliveries.

Port

An existing deep-water port will provide access to the property via Lake Superior, enabling the products

to reach customers in Ontario and beyond. Plans are in place to refurbish the existing port. An existing

warehouse adjacent to the deep-water port will be utilized for offloading spodumene concentrate from

the Great Lakes freighters. The warehouse will be refurbished and retrofitted with material handling

equipment to receive the spodumene concentrate.

Rail

A CN Rail line runs along the property dead ending just east of the property. A spur from the rail line

currently enters from the northeast corner. The rail spur splits into multiple spurs and enters the existing

warehouse adjacent to the deep-water port. Additional spurs will be added to allow for spodumene

concentrate offload and analcime load out. The existing spurs entering the warehouse will require

refurbishment. Rail will be the primary method used for the delivery of spodumene concentrate when the

lithium mines in the region come online in the years to come. Rail will also be utilized to transport

reagents to site and byproducts from site.

Spodumene Concentrate Storage

After being offloaded the spodumene concentrate will be conveyed from the rail and deep water port

facilities to a spodumene concentrate storage building. The facility will provide dry storage feed buffering

for management of feed material and inventories, ensuring stable continuous operation of the process.

Fresh Water

Fresh water is required for the process, a freshwater intake is envisioned in Lake Superior.

Potable Water and Sewage

The property is serviced by Thunder Bay municipal sewage and potable water utilities.

Other Utilities

Two 115kVA power lines run adjacent to the property to the north. An electrical substation will be

installed to connect to the grid power and provide electricity to the process. Natural gas is available on

site and will be primarily used for heating in the calciner process, and for building area heating.

Analcime Storage

A by-product, mix of Analcime and calcium carbonate will be produced from the process. The by-product

material will be dried and conveyed to the analcime storage building. The Analcime material can be

loaded onto railcars and shipped externally to customers to be used in industrial applications and

construction material such as concrete additive.
