In early 2022 Adventus announced a US$235.5 million stream/offtake project finance package for Curipamba with Wheaton Precious Metals and Trafigura - The package consists of $180 million in precious metal stream financing from Wheaton and a $55 million loan and offtake agreement with Trafigura.  This financial commitment is a major milestone for the project, and secures the ability of Adventus/Salzaar to further optimize and begin construction of the Curipamba project.


In December 2016, Altius effectively founded Adventus through an IPO process to liberate an extensive portfolio of zinc exploration projects in Ireland and Eastern Canada that was opportunistically assembled over 4 years. Altius received shares of Adventus and underlying project-based royalties on projects it vended in Ireland and Newfoundland.

Altius later acquired the Curipamba project royalty from Resource Capital Fund (RCF) in 2019 for US$10 million to secure royalty exposure on this high caliber asset. This also aligned Altius founding equity stake in Adventus with a royalty covering its Ecuador focus. Further details on Curipamba project can be found here.
