ALTIUS REPORTS Q3 2025 EXPECTED ATTRIBUTABLE REVENUE(1)

Altius Minerals Corp. expects Q3 (third quarter) 2025 attributable royalty revenue (1) of approximately $21.2-million.

Base and battery metals (primarily copper) revenue of $7.4-million for the quarter reflects higher realized prices and copper stream deliveries at Chapada.

The corporation's preliminary cost of sales for the Chapada copper stream, excluding any depletion, is $2.1-million for the quarter.

Potash portfolio revenue during the quarter was $5.5-million, reflecting higher realized prices and attributable volumes.

Iron ore royalty revenue in the form of dividends from Labrador Iron Ore Royalty Corp., which serves as a pass-through vehicle for royalty income and equity dividends related to the operations of Iron Ore Company of Canada, was $1.5-million for the quarter.

Renewable energy royalty revenue of $3.3-million reflects the continuing ramp-up of operational-stage portfolio projects and income related to the financing of interconnection deposits.

Interest and other revenue reflects $3.1-million of interest income on the corporation's increased cash balance following receipt of proceeds from the Orogen Royalties acquisition by Triple Flag Precious Metals and the sale of the corporation's 1.0-per-cent net smelter return (NSR) royalty on the Arthur project in Nevada.

(1) Non-GAAP (generally accepted accounting principles) financial measures

Management uses the following non-GAAP financial measures: attributable revenue, attributable royalty revenue, adjusted earnings before interest, taxes, depreciation and amortization (EBITDA), adjusted operating cash flow and adjusted net earnings (loss). Management uses these measures to monitor the financial performance of the corporation and its operating segments, and believes these measures enable investors and analysts to compare the corporation's financial performance with its competitors and/or evaluate the results of its underlying business. These measures are intended to provide additional information, not to replace international financial reporting standards (IFRS) measures, and do not have a standard definition under IFRS and should not be considered in isolation or as a substitute for measures of performance prepared in accordance with IFRS. As these measures do not have a standardized meaning, they may not be comparable with similar measures provided by other companies. Further information on the composition and usefulness of the non-GAAP financial measures, including reconciliation to their most directly comparable IFRS measures, is included in the non-GAAP financial measures section of the company's MD&A (management's discussion and analysis).

About Altius Minerals Corp.

Altius's strategy is to create per-share growth through a diversified portfolio of royalty assets that relate to long-life, high-margin operations. This strategy further provides shareholders with exposures that are well aligned with sustainability-related global growth trends, including the electricity generation transition from fossil fuel to renewables, transportation electrification, reduced emissions from steelmaking and increasing agricultural yield requirements. These macro trends each hold the potential to cause increased demand for many of Altius's commodity exposures, including copper, renewable based electricity, several key battery metals (lithium, nickel and cobalt), clean iron ore and potash. In addition, Altius runs a successful project generation business that originates mineral projects for sale to developers in exchange for equity positions and royalties. Altius has 46,276,054 common shares issued and outstanding that are listed on Canada's Toronto Stock Exchange. It is included in each of the S&P/TSX Small Cap, the S&P/TSX Global Mining and the S&P/TSX Canadian Dividend Aristocrats indices.
