PJ083 - Plant Control System (PCS) Hardware - Nolans Project

Overview Arafura Rare Earths Limited is seeking Expressions of Interest (EOI) for the supply of Plant Control System (PCS) Hardware for the Nolans Project in the Northern Territory. About Arafura Rare Earths Limited is an Australian, ASX-listed company (ASX:ARU) focused on the responsible future production of the rare earths elements Neodymium and Praseodymium (NdPr) and heavy rare earths from its Nolans Project in the Northern Territory. The Nolans Project, 135 kilometres north of Alice Springs, is a fully permitted, construction-ready, single site ore-to-oxide project with an anticipated mine life of 38 years. As a fully integrated operation, Nolans will encompass a mine, process plant (comprising beneficiation, extraction and separation plants) and related infrastructure. The Project is strategically located in the Northern Territory and is recognised as a globally significant and strategic NdPr project which, once developed, will become a major supplier of these critical minerals to the high-performance NdFeB permanent magnet market. The Nolans Project has made strong progress during the first half of FY2026 and remains on track towards a Final Investment Decision (FID), subject to completion of funding and offtake arrangements. Hatch has been appointed as EPCM contractor for the Nolans Project. Arafura is transitioning execution management of the Project to Hatch, and as the execution plan and procurement packaging are finalised, Hatch will be the primary contact for procurement and contracting engagement.
