Tembo Capital initially acquired the 2.5% NSR as part of a 3.18% NSR financing with Resource Capital Funds in 2020. The remaining portion is now held by Elemental Altus Royalties.

ASCU president CEO and director George Ogilvie said: “We are pleased to see the royalty move to a top calibre royalty and streaming company, with a history of participating in project financing packages and a positive prior experience with our management team.

“We believe that Royal Gold, as the acquirer, is yet another strong endorsement and recognition of the Cactus Project and its go-forward plan, by a sophisticated mining financier. Our team has dedicated itself to growing the asset to a significant size, securing water, permits, community support and, as reflected in our 2024 PEA [preliminary economic assessment], demonstrating a capital efficient project with robust forecast economics.

“We will continue to de-risk and advance Cactus as we move forward with various technical studies, through pre‑feasibility to definitive feasibility study, to an eventual final investment decision.”
