August 14, 2025 | St. John’s, Newfoundland

Altius Minerals Corporation (TSX: ALS) (OTCQX: ATUSF) Altius Minerals Corporation (“Altius”) has

received a final award decision by an arbitration tribunal relating to the extents of its royalty interests within

the emerging Silicon gold district (Arthur Gold district) in Nevada.

The tribunal has determined that the lands that are subject to the Altius 0.5% NSR royalty under the royalty

agreement between the parties dated Feb. 20, 2015 include the entirety of those encompassed within the

26.8 km 2 base area of interest (base AOI) described in the royalty agreement and also additional areas

around the base AOI that total approximately 168.8 km2, for a combined royalty area within the district that

totals approximately 195.6 km2.

The final award meets the royalty area requirement set out in the recent sales agreement between Altius

and Franco -Nevada Corporation for a 1.0% NSR royalty that is to cause an additional US$25 million

contingent payment to Altius, following the expiry of any relevant appeal or challenge periods.

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 global growth trends including increasing electricity based market share within energy usage,

global infrastructure build and refurbishment growth, increased EAF based steelmaking, steadily

increasing agricultural fertilizer requirements and the enhanced appetite for financial asset diversification

through precious metals ownership. These macro-trends each hold the potential to cause higher demand

for many of Altius’s commodity exposures including potash, high purity iron ore, renewable energy, base

metals, and gold. In addition, Altius runs a successful Project Generation business that originates mineral

projects for sale to developers in exchange for royalties and that has a demonstrated track record of

driving outsized direct returns from its overall royalty investment portfolio. Altius has 46,315,304 common

shares issued and outstanding that are listed on Canada’s Toronto Stock Exchange. It is a member of

both the S&P/TSX Small Cap and S&P/TSX Global Mining Indices and the S&P/TSX Canadian Dividend

Aristocrats Index.
