Toronto, Ontario--(Newsfile Corp. - November 18, 2024) - Avalon Advanced Materials Inc. (TSX: AVL) (OTCQB: AVLNF) ("Avalon" or the "Company") is pleased to announce that it has completed CAD $3,500,000 in convertible debenture financing from its significant shareholder, SCR-Sibelco NV ("Sibelco"), a global leader in material solutions and a leader in the mining and processing of high purity quartz. The proceeds will be used to fund the advancement of its Lake Superior Lithium Project in Thunder Bay, the Nechalacho REE and Zirconium Project in the Northwest Territories, and for working capital and general and administrative expenses.

Sibelco has provided an additional funding of CAD $3.5 million to Avalon by way of an amended and restated debenture (the "Debenture"). The Debenture replaced the Company's existing CAD $3.0 million convertible secured debenture (dated 14 June 2023 and amended on 9 November 2023) and have a principal amount of CAD $6.5 million.

Scott Monteith, CEO and Director of Avalon commented, "We are very pleased to have secured this new $3.5 million financing from our JV partner Sibelco. We are preparing our new Mineral Resource Estimate at the Separation Rapids JV project, and this new funding will enable us to accelerate the technical studies on our Lake Superior Lithium Project."

Avalon has applied for both provincial and federal funding in support of the Lake Superior Lithium Project in Thunder Bay. Avalon also recently published the results of a Preliminary Economic Assessment (PEA) on September 3, 2024 showing positive results, including an after-tax net present value (NPV) of CAD $4.1 billion at an 8% discount rate and Capex of CAD $1.3 billion.

The Debenture bears interest at 7.5% per annum, with the principal and accrued interest payable on maturity, which will be November 18, 2026. Should the Debenture not be repaid by Avalon at maturity, Sibelco has the right to (a) convert the outstanding principal and accrued interest into additional common shares of Avalon at a price equal to the greater of (i) the 15-day volume-weighted average price of the Company's common shares on the TSX immediately prior to the exercise of this right and (ii) the minimum price allowed by the Toronto Stock Exchange ("TSX") or (b) convert the outstanding principal and interest into additional common shares of the Avalon-Sibelco joint venture company, Separation Rapids Ltd. ("SRL"), based on a pro-rated formula.

If the entire amount of the Debenture and accrued interest is converted at maturity, then Sibelco's JV interest in SRL will be increased by 30%. This would result in a change in the participating interests of Sibelco and Avalon in SRL to 90% and 10%, respectively. Sibelco will also have the right to exercise its conversion rights prior to maturity if Avalon does not make certain reductions in its corporate and administrative costs. The Debenture will continue to be secured by a pledge of Avalon's shares in SRL.
