Latest Developments
Kinterra Capital has completed the acquisition of Australia’s New World Resources, gaining control of the high-grade Antler copper project and announcing a review of new processing technologies to bolster domestic copper output.

“Including Antler, Kinterra now controls approximately 175 000 tonnes of annual copper production capacity across its US portfolio – from Antler in Arizona, White Pine, in Michigan, and Pumpkin Hollow and the adjacent Southwest openpit, in Nevada,” according to Kinterra co-managing partner Cheryl Brandon.

“With an average grade of 3.8% copper equivalent, Antler ranks among the highest-grade underground copper development projects globally,” said Kinterra co-managing partner Kamal Toor. 

“[Antler’s] combination of exceptional grade, capital efficiency and strategic location makes it capable of materially contributing to near-term US copper supply.”
