Kinterra expands its US copper platform by completing the acquisition of the Antler Copper Project
Initiates review of leaching technologies to supplement U.S. copper production
Kinterra Capital Corp. (“Kinterra”) today announced that it has expanded its US copper platform by completing the acquisition of 100% of the issued and outstanding shares of ASX-listed New World Resources Ltd (ASX: NWC,OTC:NWCBF) (“New World”) and its flagship Antler Copper Project (“Antler”) in Arizona.
“Including Antler, Kinterra now controls approximately 175,000 metric tons of annual copper production capacity across its U.S. portfolio – from Antler to Arizona, White pine in Michigan and into Pumpkin Hollow and the adjacent Southwest Open Pit Nevada,” said Cheryl Brandonco-managing partner at Kinterra. “This acquisition strengthens our role as a cornerstone of the U.S. copper industry. Our strategy expects to provide a secure source of copper supply to the electric grid, the clean energy industry and technology applications.”
Kinterra acquired the New World through a compulsory acquisition August 14, 2025after securing more than 90% of New World’s shares under its takeover bid, in accordance with Australia Corporations Act 2001 (Cth). The total amount for the transaction is approx $160 million.
New World owns Antler, a historically high-quality underground copper company in the West Arizonaas well as two copper exploration projects within Arizona And New Mexico. Located in one of the most established copper jurisdictions in the world, Antler benefits from a strong infrastructure, skilled mining workforce and supportive policy frameworks for the development of domestic critical minerals.
“With an average grade of 3.8% copper equivalent, Antler is among the highest quality underground copper development projects worldwide, almost six times the global development average,” said Kamal Toor, co-managing partner at Kinterra. “Its combination of exceptional quality, capital efficiency and strategic location positions it to make a material contribution to the U.S. copper supply in the near term.”
The U.S. government has made secure and diversified mineral supply chains a national priority. Independent analyzes from the IEA and S&P Global predict a structural copper shortage in the 2030s without accelerated mine development and new refining capacity. Today, the U.S. imports nearly one million tons of refined copper annually – roughly half of U.S. consumption – underscoring the strategic importance of developing high-quality domestic resources like Antler.
Kinterra launches a review of sulfide leaching technologies to advance domestic production of copper cathodes
Kinterra has also begun evaluating and developing sulfide leaching processing technologies aimed at enabling domestic copper cathode production across its U.S. portfolio. The initiative will evaluate the application of established methods capable of converting sulfide ores directly into refined copper United States buyer portfolio.
“Kinterra is working to help shape a balanced domestic processing strategy – one that aligns industrial policy with market competitiveness,” Mr Toor continued. “By assessing next-generation leaching technologies, we aim to unlock value from our resource base and retain a greater share of the U.S. copper value chain”
Collaboration with leading technology developers takes place at an early stage; the first tests and pilot plans are expected in early 2026.
