09:14 AM EDT, 04/21/2026 (MT Newswires) -- Altius Minerals ( ATUSF ) said Tuesday that it expects a year-on-year increase in attributable royalty revenue for the first quarter.

The company estimated its ARR to reach C$26.4 million in the three months ended March 31, rising from $15.0 million in the year-ago period.

This includes base metals revenue jumping to $9.1 million from $6.8 million a year earlier, reflecting higher realized copper prices and timing of copper stream deliveries from the Chapada mine, as well as higher revenue from the Voisey's Bay operation. Its preliminary cost of sales for the Chapada copper stream, excluding any depletion, was $2.5 million for Q1 2026.

It also includes potash revenue increasing to $4.5 million from $3.9 million due to higher realized prices and lithium revenue surging to $5.4 million from $51,000 following its acquisition of Lithium Royalty.

ALS cited iron ore royalty revenue in the form of dividends from Labrador Iron Ore Royalty ( LIFZF ) of $1.6 million for the quarter, down from $1.9 million last year, but also said electricity royalty revenue totaled $3.6 million, increasing from $1.6 million.

Shares in ALS were down $0.52 or 1% to $51.25 in Canada yesterday.
