Located in the Gascoyne region of Western Australia, the Yangibana Project contains one of the most highly valued deposits of NdPr in the world with an NdPr to Total Rare Earth Oxide ratio of up to 52% in some areas of the orebody. With an initial mine life of 17 years, the Yangibana Project is expected to become a globally significant source of NdPr, a critical component in the manufacture of permanent magnets used in advanced technology products including electric vehicles, renewable energy, humanoid robotics, and digital devices. The Yangibana Project is fully permitted for immediate development and is well-timed to meet the forecast supply gap for rare earth elements accelerated by the growth in electric vehicles and wind turbines, both vital for the global energy transition. It will be developed in two stages with an initial focus on the construction of the mine and beneficiation plant to produce 37,000 tonnes per annum1 of mixed rare earth concentrate. Hastings recognises in its geological model and mine plan the potential for a multi-commodity recovery process stream which underpins the economic recovery of rare earth minerals and associated critical minerals like ferro-columbite, and hafnium-enriched zircon.
