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 Li ........

Conventional open pit dry mining in free-dig sand using D11 dozers feeding mobile Dozer Mining Units (DMUs), with in pit tailings deposition and progressive backfill and rehabilitation.

Seeds will be collected from vegetation across the orebody prior to the vegetation being removed by heavy mobile equipment. Collected seeds will be used in the mine rehabilitation process.

Topsoil and Subsoil material will be stripped by dozer or scraper and will be either placed in stockpiles in the vicinity of the pit or placed directly on top of recontoured tails areas. Both topsoil and subsoil will be managed to minimize stockpile duration.

Overburden, where present, will be removed by large capacity bulldozers and placed in the pit void immediately behind the mined-out ore. Interburden removal is carried out by an excavator and the EMU (Excavator Mining Unit). No drill and blast is required.

Ore is pushed by a fleet of D11 manned carry dozers to DMUs (dozer trap), oversize material is wet screened separated from the slurry undersize which is subsequently pumped to the ore processing facilities. The DMU’s are skid mounted and moved on average every 6 days during the LOM.The EMU alternates between overburden removal and ore processing during periods of DMU movement.

Grade control of the ore has been defined through the mine optimisation and scheduling process to achieve the target feed head grade to the plant. Operation efficiency of t ........
