ST. JOHN'S, Newfoundland and Labrador - Altius Minerals Corporation (ALS:TSX) (ATUSF: OTCQX) ('Altius' or the 'Corporation') expects to report Q2 2022 annual attributable royalty revenue of $28.2 million, which compares to $21.9 million of attributable royalty revenue recorded in Q2 2021 and represents a new quarterly record for the Corporation.

Potash portfolio revenue during the quarter was $11.5 million, which compares to $4.5 million in the comparable quarter of 2021, reflecting significantly higher average realized prices as well as price reconciliation adjustments of $0.9 million related to 2021 sales. On a year-to-date basis, potash revenue of $21.4 million exceeds the $19.3 million revenue reported for the full year 2021.

During the quarter both operators of the mines comprising the Corporation's potash royalty portfolio signalled intentions to incrementally increase production rates over the next few years through debottlenecking and growth investments in response to projected global supply deficits for the key fertilizer component.

Base and battery metal (primarily copper) revenue of $8.4 million for the quarter compares to $9.4 million reported for the second quarter of 2021 due to reduced attributable production volumes.

Mine production at the 777 mine ended during the quarter upon the depletion of reserves, with small royalty payments expected for the balance of this year related to residual processing and sales. Adventus Mining and Salazar Resources reported during the quarter that they have received technical approval of their Environmental and Social Impact Assessment, a Certificate of Technical Feasibility for the construction of tailings and waste rock facilities, and a preliminary commitment with regard to an Investment Protection Agreement for the Curipamba - El Domo copper-gold project in Ecuador, which is subject to an Altius NSR royalty. Lundin Mining reported that it continues to aggressively advance its new high-grade Sauva discovery, which is located 15 km north of current mining operations at Chapada on lands subject to Altius's copper streaming agreement. Vale also announced that it continues to advance development of the Eastern Deeps nickel-copper cobalt mine at Voisey's Bay with initial production targeted for later this year.

Iron ore revenue in the form of dividends from Labrador Iron Ore Royalty Corp. (LIORC) was $2.9 million compared to $5.0 million in Q2 2021 due to higher sustaining and growth capital spending and lower declared dividends by the Iron Ore Company of Canada (IOC). LIORC serves as a pass-through vehicle for IOC production-based royalty revenues and equity dividends. In the second quarter of 2022, Altius purchased additional shares of LIORC to hold approximately 3.2 million shares at the dividend record date.

Thermal (electrical) coal revenue of $4.5 million during the current quarter compared to $2.1 million during the second quarter of last year. The current quarter revenue included approximately $1.6 million as an adjustment to royalties received during 2021 and Q1 2022 that mainly relates to inflation-based rate escalation provisions of the Genesee royalty agreement.

Renewable energy and other royalty revenue included approximately $0.8 million related to the Corporation's 59% interest in Altius Renewable Royalties Corp. (ARR:TSX), compared to $0.06 million in the same quarter last year.

AngloGold Ashanti continued an aggressive delineation and exploration focussed program at its new Silicon Project gold discovery in Nevada, while Altius indicated during the quarter that it is considering various strategic alternatives for its NSR royalty interest in the project.

About Altius

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 47,764,588 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.
