Not Applicable for the current ASX Release.
The data discussed in the current ASX Release deals with two (2) different multispectral spaceborne datasets:
o [i] Advanced Spaceborne Thermal Emission and Reflection Radiometer ("ASTER"); and
o [ii] Sentinel-2.
The data is initially recorded by satellites and the processing and interpretation were delivered in the coordinate
system of WGS84 Zone 19S.
The survey control is appropriate for interpretation of the processed ASTER and Sentinel-2 to deliver regional
targets as surface expressions that are likely to represent surface expressions of high-sulphidation epithermal
and/or porphyry-style mineral systems.
Follow-up on the ground exploration activities will be required to confirm the remote sensing interpretation of
the geology.
