29Metals has reported new drilling results at its Golden Grove operations in Western Australia, confirming further high‑grade copper–zinc–gold mineralisation at the Oizon deposit within the Gossan Hill project. Resource extension and resource conversion drilling both intersected additional ore-grade material, supporting Oizon’s progression as a key emerging underground ore source for the site’s existing processing plant. The results indicate scope to grow mine life and re-optimise stope sequencing, with geotechnical and ventilation planning likely to focus increasingly on Oizon as drilling tightens the resource model.

American Ocean Minerals has completed its three‑week Expedition 7 in the Cook Islands’ EEZ, using the 196‑foot research vessel Anuanua Moana to survey 53 sites and collect 60 box cores, 62 multicores and 4,059 physical samples over Moana Minerals’ EL3 polymetallic nodule licence. The campaign integrates sediment physico‑chemistry, macrofaunal and meiofaunal counts, foraminiferal studies, eDNA, bathymetry and water‑column biomass data to define baseline ecological conditions and resource variability. Results will feed directly into Moana Minerals’ Environmental Impact Statement due H1 2027 and a pre‑feasibility study targeted for H2 2026.

REalloys is raising US$100 million via a securities purchase agreement to fund a vertically integrated mine-to-magnet rare earth supply chain centred on its Hoidas Lake project in Saskatchewan and downstream magnet manufacturing in Euclid, Ohio. The company is partnering with the Saskatchewan Research Council to scale heavy rare earth separation, refining and metallisation, and has a 15-year offtake for concentrates from Critical Metals’ Tanbreez project in Greenland. Bloomberg reports REalloys may also build a rare earth separation plant at the US Army’s Tooele Army Depot in Utah, pending government approval.
