- Business
- New Frontier Minerals Limited is an exploration and development company focused on identifying and advancing mineral assets with potential for economic mining operations across Australia and Zambia. The group concentrates on copper, cobalt, rare earth elements (including heavy rare earths), niobium, uranium, and related metals, deploying a disciplined exploration and development program to convert prospects into commercially viable projects. Headquartered in Perth, Western Australia, the company operates project sites in Australia’s Northern Territory, Queensland, and New South Wales, as well as exploring opportunities in Zambia and Canada, under a diversified commodity mandate. Founded in 2010, the company rebranded from Castillo Copper Limited in 2024 to reflect a broadened portfolio and strategic shift toward multi-commodity mineral exploration and near-term development.
