AVALON ANNOUNCES CLOSING OF BROKERED LIFE FINANCING OF APPROXIMATELY C$18.65 MILLION TO ADVANCE ITS RARE EARTH AND LITHIUM PROJECTS IN CANADA

Avalon Advanced Materials Inc. has closed its previously announced brokered private placement under the listed issuer financing exemption. Pursuant to the offering, the company issued an aggregate of 133,218,180 non-flow-through units of the company and an aggregate of 30,769,231 flow-through units of the company for aggregate gross proceeds of $18,653,999.83.

Each non-FT unit is composed of: (i) one common share of the company; and (ii) one common share purchase warrant of the company. Each FT unit is composed of: (i) one common share, each of which will qualify as a flow-through share within the meaning of Subsection 66(15) of the Income Tax Act (Canada); and (ii) one warrant, each of which will qualify as a flow-through share within the meaning of Subsection 66(15) of the tax act. Each warrant will entitle the holder to acquire one common share at an exercise price of 17 cents per warrant share for a period of 36 months from the closing date (as defined herein).

The net proceeds of the offering are expected to be used to finance, among other things:

• The preparation of an updated feasibility study for the Nechalacho rare earth and zirconium project to advance project readiness and support continuing strategic partnership discussions;
• The preparation of a feasibility study related to the company's planned Thunder Bay lithium refinery to advance project readiness and support continuing strategic partnership discussions;
• The repayment of outstanding convertible notes; and
• Working capital and general corporate purposes.

"This financing marks a transformative milestone for Avalon. With the $18.65-million in proceeds, we are poised to significantly accelerate the advancement of our rare earth and lithium assets, fortify our balance sheet, and position Avalon at the heart of the global shift toward establishing more secure critical minerals supply chains," said Scott Monteith, president and chief executive officer. "As nations increasingly prioritize resilience and independence in sourcing rare earths and lithium, Avalon is well positioned to emerge as a key North American partner and enabler on that journey."

The offering was led by Canaccord Genuity Corp., acting as lead agent and sole bookrunner, and SCP Resource Finance LP. In connection with the offering, the agents received aggregate cash commission equal to 6.0 per cent of the aggregate gross proceeds raised pursuant to the offering, financed through the non-flow-through capital resources of the company, and additional consideration in the form of broker warrants equal to 6.0 per cent of the number of non-FT units and FT units sold pursuant to the offering. Each broker warrant will entitle the holder thereof to acquire one common share of the company at a price of 11 cents per broker warrant share for a period commencing 61 days following the closing date and ending 36 months following the closing date.

The offering was completed pursuant to the listed issuer financing exemption (as defined in National Instrument 45-106 (Prospectus Exemptions)), as amended by Coordinated Blanket Order 45-935 (Exemptions from Certain Conditions of the Listed Issuer Financing Exemption), and the securities issued to purchasers in the offering are not subject to a hold period pursuant to applicable Canadian securities laws. The offering is subject to the final approval of the Toronto Stock Exchange.

The offering supports Avalon's strategy to advance its rare earth and lithium assets and play a meaningful role in strengthening the foundation of a resilient North American critical mineral supply chain.
