Avalon Closes $1,300,000 Lind Financing and

Advances Analcime Test Work Project

Toronto, Ontario--(Newsfile Corp. - July 25, 2025) -

Avalon Advanced Materials Inc.

(TSX: AVL)

(OTCQB: AVLNF) ("Avalon" or the "Company") is pleased to announce that it has closed the

$1,300,000 second drawdown of its up to $15,000,000 convertible security funding agreement (the

"Funding Agreement") with Lind Global Fund II, LP, an entity managed by The Lind Partners, a New York

based institutional fund manager (together "Lind").

The details of the Funding Agreement are contained

in the Company's

news release dated July 21, 2025

.

With the second drawdown now complete, Avalon will allocate the funds toward advancing its strategic

projects - including byproduct innovation through its subsidiary Lake Superior Lithium Inc., as well as

supporting general corporate initiatives.

Analcime Research Project Update

Avalon is pleased to provide an update on its ongoing Analcime Utilization Project, part of a broader

initiative to enhance the value of byproducts generated from lithium processing. This initiative is being

advanced by Avalon's wholly owned subsidiary, Lake Superior Lithium Inc. ("LSLi"), and is supported by

Ontario's Critical Minerals Innovation Fund ("CMIF"), which recently released the second tranche of a

$500,000 funding commitment.

The project is focused on developing innovative solutions for analcime - the byproduct from lithium

hydroxide production at the future LSLi Facility. Initial research suggests that analcime's pozzolanic

properties - its ability to react with calcium hydroxide in cement - may help improve the durability and

carbon profile of concrete. These findings align with the Ontario Ministry of Transportation's broader

efforts to adopt low-carbon construction materials and sustainable construction techniques.

Hydrometallurgical test work is currently underway by Metso Finland Oy to produce analcime samples

from spodumene concentrate. Additional funding will support ongoing research and development into its

use as a sustainable supplementary cementitious material for low-carbon infrastructure applications.

"This innovative project promises sustainability benefits through reduced carbon emissions, opens new

revenue opportunities, and represents an opportunity for Avalon to contribute to the repair and expansion

of provincial highways," said Scott Monteith, President and CEO of Avalon.

The analcime project helps Avalon unlock additional value through the establishment of its LSLi Facility

by repurposing a key byproduct of lithium processing. Avalon is proud to play a strategic role in securing

Ontario's economic future and positioning both the province and the company as leaders in the global

critical mineral's economy and among the most competitive in the G7.
