Castillo Copper Ltd. ( (AU:NFM) ) has provided an announcement.
New Frontier Minerals has secured technical assessment approval for the Mining Lease Application at its Big One Copper Deposit in North-West Queensland, a key step toward potential near-term open-cut copper production using Austral Resources’ nearby Mt Kelly processing plant. The project hosts a JORC-compliant resource of 2.1Mt at 1.1% copper, including near-surface stockpiles that support a low-strip development concept, and the company is considering further drilling to extend high-grade mineralisation.
Alongside advancing Big One, New Frontier is progressing evaluation of tungsten potential and untested heavy rare earth targets at its Harts Range Project, and planning low-cost metallurgical test work on Pomme core, including trials with proprietary Flash Joule Heating technology. Backed by about A$2.62 million in working capital and expected grant and R&D rebate inflows, the company highlights a strengthening macro backdrop for copper that underscores the strategic importance of its Mt Isa–region copper portfolio for investors and potential offtake partners.
