A gross overriding royalty is a contractual right that pays its holder a fixed percentage of revenue from the sale of produced minerals, oil, or gas, taken before the producing company deducts operating or capital costs. Think of it like a landlord who collects a slice of every sale from a shop on the property rather than sharing in the shop’s profits; it reduces the producer’s cash receipts on each unit sold without requiring the royalty holder to share costs or ownership. Investors care because it lowers future cash flow and project valuation per unit produced, can be transferable, and affects how attractive a resource or company appears compared with similar assets without such claims.
net smelter returns royaltyfinancial
A net smelter returns (NSR) royalty is a contractual right to receive a percentage of the revenue generated from mined minerals after the ore has been processed and sold, with common deductions for refining, smelting and transport costs. Think of it like a landlord taking a slice of a tenant’s monthly sales after the tenant pays basic operating bills. Investors care because an NSR affects the future cash flow and valuation of a mining project and shifts some upside and downside risk away from the operator to the royalty holder.
ni 43-101regulatory
A Canadian regulatory standard that sets the rules for how mining and exploration companies must report mineral resources and reserves, requiring technical reports prepared or signed off by an independent, certified expert. It matters to investors because it creates a consistent, transparent “inspection report” for mining projects, making it easier to compare prospects, judge the reliability of claims, and assess geological and financial risk before investing.
epithermal mineralizationtechnical
Epithermal mineralization is the concentration of metals and minerals deposited by hot, metal-bearing fluids at relatively shallow depths near the Earth's surface, typically forming veins, breccias and stockworks. It matters to investors because these deposits commonly host high-value metals like gold and silver in concentrated zones — similar to how minerals precipitate around a hot spring — so they are key targets in exploration and can affect a mining project's potential value and risk profile.
lithium carbonatetechnical
A white, crystalline compound containing lithium that is a key raw material for electric vehicle and grid-storage batteries and is also used as a medicine for certain mood disorders. Think of it as a concentrated ingredient — like flour for baking — where changes in its price, supply or purity directly affect makers of batteries, automakers, and mining companies, so investors watch it as a bellwether for demand and production costs.

Portfolio Highlights
Buffalo Potash Corp. (TSX.V: BUFF) ("Buffalo") is a Saskatchewan-based potash developer pursuing a modular approach to solution mining through its patented Horizontal Line‑Drive (HLD) technology. Altius participated in Buffalo's recent private placement (see announcement on June 29, 2026) in the amount of $3 million. Furthermore and separate from the financing, Altius and Buffalo have executed a non-binding memorandum of understanding to explore the potential development of royalty interests on Buffalo's Saskatchewan potash properties, including the facilitation of negotiations with private mineral rights holders and a right to participate in exclusive discussions regarding any future royalty or streaming financing on Buffalo's various land holdings. To that extent, Altius has also acquired from a private owner a 0.16% gross overriding royalty on Buffalo's greenfields stage Odessa Project.
Gilpas Resources Ltd. ("Gilpas") is private Canadian company which is advancing a series of iron oxide-copper-gold (IOCG) properties in northern Sweden, with a focus on the Kåivåive Project. Altius recently closed a $1.5 million private placement in Gilpas which gives Altius a 20% interest in Gilpas and a 0.5% net smelter returns royalty on all of Gilpas's Swedish properties, with certain additional royalty purchase rights on the Kåivåive project and further equity participation rights. Altius will work closely with Gilpas on technical matters related to the project advancement.
As part of its ongoing 50/50 gold exploration alliance in Nevada with Orogen Royalties Inc. (TSX-V: OGN) ("Orogen"), the Table Mountain project option agreement was closed with Toogood Gold Corp.

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, electricity, 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 55,748,220 common shares issued and outstanding that are listed on Canada’s Toronto Stock Exchange. It is a member of the S&P/TSX Composite and S&P/TSX Global Mining Indices and the S&P/TSX Canadian Dividend Aristocrats Index.
