Snapshot	The Coburn project is one of the largest new mineral sands development projects in the world, underpinned by an attractive high-value product suite, conventional design and low-cost operation. Construction at the Coburn project commenced in May 2021 and was completed in two stages with contractor handover of the WCP (ready for ore commissioning) in November 2022 and the downstream MSP in late March 2023. Coburn Project Expansion Opportunity During the 2023 year, Strandline Resources progressed a scoping study on the potential to increase Coburn’s production rate by up to 50%. Preliminary investigations highlight the potential strong capital and operating cost efficiencies of scaling up Coburn. The study is targeting to increase total HMC production to +320,000 tonnes per annum. A fourth Dozer Mining Unit and additional WCP modules are being contemplated for the expansion.

Deposit type

• Mineral sands

Summary:

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% lmenite

-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
