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.  The ESIA technical approval from the government of Ecuador was received in Q4 2021, with final environmental approvals now expected in the second half of 2023 as per the project update announcement from Adventus dated September 12, 2022. 


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 the Curipamba project can be found here.
