The mineralisation style most prevalent across the Projects is heavy mineral sands containing valuable heavy mineral (VHM) concentrate of zircon, rutile, leucoxene, ilmenite, and monazite (which contain Rare Earth Elements – REE).
The Douglas Project’s deposits are characterised by being coarse grained with mean diameter grain size ranging from 130 µm to 160 µm, and the Goschen Central Project and the Watchem Project are fine grained.
These deposits are of two principal types, which are the coarser-grained “strand-style” occurrences and the finer-grained accumulations known locally as Wimmera Industrial Mineral (WIM) style.
The Goschen Central Project areas have wide zones of mineralisation and high-grade cores (>10 % heavy minerals (HM)), low stripping ratios, and a heavy mineral suite comprising 60 % to 80 % of VHM concentrate. The Watchem Project is a WIM style mineral sands project located in a region being developed for this style of deposit.
The Projects are located in western and northern Victoria (Figure 1), which is favourable for access and infrastructure. The Tenements are mostly freehold title and not subject to Native Title (except for EL7544 and ELA7642, which are subject to a Native Title determination), and road, rail access, and grid power are already well provided in the region. The area is almost totally cleared and used for dry land farming.
The Projects are located in the Murray Basin of south-eastern Australia, which is a low-lying, saucer-shaped intra-cratonic depression containing thin, flat-lying Cainozoic sediments. It extends approximately 850 km from east to west and 750 km from north to south, covering an area of 300,000 km2 of south-western New South Wales, north-western Victoria and south-eastern South Australia.
