Strandline Resources entered voluntary administration on 21 February 2025, with McGrathNicol appointed as receivers and Cor Cordis as administrators for both Strandline and its subsidiary Coburn Resources Pty Ltd. The receivers assumed control to maintain operations while pursuing a sale or recapitalization.
Iwatani Corporation has offered about A$15 million to acquire the Coburn mine, which remains under receivership and care-and-maintenance. No binding completion of the transfer to Iwatani has been publicly confirmed.
Coburn is a world-scale mineral sands deposit, containing a rich zircon-titanium HM assemblage, with 20Mt of in-situ HM, low slimes, low oversize and strong geological continuity across and along strike.Coburn’s Amy deposit was discovered in 2000 after prospectors identified that the ancient coastline at Coburn was an ideal trap-site for heavy mineral sands with its characteristic hook shape.Mineralisation consists of an accumulation of mainly aeolian sands deposited over a Cretaceous basement of clays, clayey sands and limestone. A total of 3 dune sequences containing heavy mineral are recognised across the project area.The Amy South mineralisation has a strike length of approximately 27 km, a width up to 3 km and a maximum thickness of approximately 50 metres. Amy North adds a further 6km in strike length.IHC Robbins issued (November-2018) JORC compliant Global Mineral Resource estimate of 1.6Bt HM at 1.2% THM (cut-off grade of 0.8%).Measured-Indicated resources of 726Mt at 1.3% THM contained in the Amy South deposit (doesn’t include Amy North) have been evaluated as part of the DFS and updated Ore Reserve. Amy South deposit comprises an exceptionally rich heavy mineral assemblage of 22% zircon, 12% rutile-leucoxene and 48% ilmenite.Indicated-Inferred resources extending north and along strike of the Ore Reserve, totals 709Mt at 1.2% THM which have been evaluated in the Mine Life “Extension Case” Scoping Study.
