ALTIUS REPORTS FIRST QUARTER ATTRIBUTABLE ROYALTY REVENUE1 OF $15.7M

St. John's - TSX: ALS Altius Minerals Corporation ("Altius" or the "Corporation") reports that it will release financial results

for its first quarter of 2018 on May 14, 2018 after the close of market. The Q1 2018 results will be presented in comparison with the three month period ended April 30, 2017 as a result of the recent conversion to a calendar year end.

Altius expects to report attributable royalty revenue1 of approximately $15.7 million for the three month period ended March 31, 2018, which is 17% higher compared to $13.4 million reported in the quarter ended April 30, 2017. Previously updated royalty revenue guidance for the year remains at $64 - $69 million, reflecting a higher 91.3% interest in the potash royalties that became effective March 23, 2018 and that will more fully impact subsequent quarters.

The first quarter results experienced growth from all commodity segments on a year over year comparable quarter basis. Royalty revenues benefited particularly from stronger production results from Chapada during its typically slower rainy season, production volume and price growth at the Rocanville potash mine, and a return to higher royalties from the Sheerness coal operation as mine sequencing has migrated to higher royalty paying lands. The Labrador Iron Ore Royalty Corporation paid only a minimal dividend above its base rate, as the Iron Ore Company of Canada was impacted by labour disruption. Additional details relating to individual royalty performances will be provided with the release of full financial results.
