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.
