A small area covering part of the Meadows Fault scarp and part of the adjoining Tertiary-Recent Meadows Basin has been explored for inferred sediment-hosted primary gold mineralisation that may have formed in favourable Neoproterozoic bedrock stratigraphic and structural settings. The licensee's exploration model was based mainly on the published results of CODES research conducted at the University of Tasmania, which used demonstrable country rock increases of gold-in-pyrite concentrations as a vector towards economic gold occurrences. Certain stratigraphic units of the Adelaide Fold Belt with elevated gold levels had been identified by the CODES research, and therefore Yandan targeted these units in areas containing anticlinal folds, kinks or dilational zones. Priority was assigned to those areas close to known significant gold occurrences such as the Bird-in-Hand deposit. During the first licence year, Yandan conducted an interpretation of regional TMI data imagery to detect possible structural anomalies, and one priority sediment hosted gold target was identified within EL 5946 in its north-eastern corner, where the Neoproterozoic bedrock had been folded during a geological period (Sturtian to Marinoan epochs) when there was elevated gold input to the orogen. This small anticlinal structure lies in the same stratigraphic position as the host unit of the Bird in Hand gold deposit located ~30 km to the north. During licence Year 2, 3 soil geochemical samples were collected from the tenement in September 2018 and assayed using Mobile Metal Ion (MMI) partial leach methods for assorted ions. A single rock chip sample of an iron stained quartz vein from near a fault in the Ulupa Siltstone bedrock was also collected and assayed. Although the results of the soil and rock chip sampling were sufficiently positive to warrant further work, Yandan later decided to relinquish tenure, due to what the company considered to be insurmountable issues with gaining land access.
