A large area of the northern Murray Basin lying adjacent to the SA-NSW state border and also immediately north of the Danggali Wilderness Area of South Australia has been explored for possible economic buried marine placer deposits of Tertiary heavy mineral sands (HMS). The licensee took up this extensive acreage to enable it to realise a business model which envisaged mining high-grade HMS strandline mineralisation with mobile plant equipment capable of being sequentially deployed through multiple deposits across a broad project area. This approach differs from the large-scale operations employed to date by major companies in the basin, as it would allow for the development of discrete HMS discoveries that might not have the tonnages required to sustain such traditional operations. At the time of granting, the subject EL 6139 augmented MBM’s existing large HMS exploration lease holdings in the Tararra and Central Para districts of south-western NSW. During the first licence year, activity consisted of an office-based compilation of drillhole data from open-file historical reports, and performing a preliminary analysis of it in GIS. EL 6139 contains the Oakbank, Boxwood Dam and Johnsons Dam strandline HMS deposits, which were found in the early 2000s and have had preliminary (non-JORC) resource estimates undertaken by Iluka Resources Ltd: • Oakbank 6,000 kt @ 3.6% THM • Johnsons Dam 5,000 kt @ 4.2% THM • Boxwood Dam 24,000 kt @ 2% THM Additional significant HMS mineralisation had been identified at Brookes Bore, which occurrence was believed to share many features in common with the Massidon WIM deposit. Strandline type HMS mineralisation previously encountered at this deposit was considered to warrant further follow-up drilling. During licence Year 2, due to there being a change in the management direction of the parent company, it was decided not to renew the licence.
