ASX-listed New World Resources has secured a key regulatory milestone for its Antler copper project in Arizona, with the US Bureau of Land Management (BLM) granting a determination of National Environmental Policy Act (NEPA) adequacy for its mine plan of operations (MPO).
The decision, New World says, sets the project on a clear 12-month timeline for full federal approval.
The MPO, submitted in January last year, is the only federal permit required for the project. The BLM has determined that the MPO will be assessed under an Environmental Assessment (EA), which will evaluate potential environmental, cultural, and social impacts under the NEPA.
“We couldn’t be more pleased with the progress of our permitting process to date. Receiving the determination of NEPA adequacy and confirmation that our mine plan of operations will be evaluated under an EA puts us on a clear 12-month path to achieving full federal approval,” said New World MD and CEO Nick Woolrych.
He further stated that with Arizona state permits expected to be issued progressively over 2025, the project remained on track for construction to begin in the second half of the year, with full operational permits expected in early 2026. The company aims to start shipping concentrate by 2027.
The permitting process aligns with recent US policy directives aimed at prioritising domestic critical minerals production. Executive orders from the White House have reinforced the importance of streamlined permitting for projects, creating a more predictable regulatory framework.
Located in northern Arizona, the Antler project is about 200 km south-east of Las Vegas and 350 km north-west of Phoenix. A prefeasibility study completed in July 2024 outlined plans for an underground mining operation, processing plant, pastefill plant, and a fully lined dry-stack tailings storage facility.
The project proposes the development of a 1.2-million-tonne-a-year underground operation with a 12.2-year life, comprising 13.6-million tonnes at 1.6% copper, 3.7% zinc, 0.6% lead, 24.5 g/t silver and 0.26 g/t gold.
About 341 100 t of copper-equivalent metal will be payable over the life-of-mine, or 30 100 t copper equivalent a year.
New World is progressing a definitive feasibility study and a financing strategy, which includes discussions with potential partners for project investment and funding through precious metals streaming and other financial structures.
“Beyond permitting, we remain fully committed to industry best practices in mine design, water management, and responsible resource development at the Antler copper project. Our development approach prioritises sustainable water use, environmental stewardship, and meaningful engagement with local communities and Tribal partners to ensure shared benefits," said Woolrych.
