Data spacing and distribution
Orientation of data in relation to
geological structure
•
Data spacing for reporting of Exploration Results.
Whether the data spacing and distribution is sufficient to
establish the degree of geological and grade continuity
appropriate for the Mineral Resource and Ore Reserve
estimation procedure(s) and classifications applied.
Whether sample compositing has been applied.
Whether the orientation of sampling achieves unbiased ⚫
sampling of possible structures and the extent to which
this is known, considering the deposit type.
If the relationship between the drilling orientation and the
orientation of key mineralised structures is considered to
have introduced a sampling bias, this should be assessed
and reported if material.
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.
Multispectral image sensors simultaneously capture image data within multiple wavelength ranges (bands)
across the electromagnetic spectrum. Each band is commonly described by the band number and the band
wavelength centre position.
The ASTER processed datasets of a resolution of 15m for Visible Near Infrared ("VNIR) or 30m for Short
Wavelength Infrared ("SWIR").
The Sentinel-2 resolution ranges from 10m to 60m dependent on bandwidth.
The survey control and data resolution 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.

The interpretation of the regional geological structures, based on a number of sources and datasets (e.g.
porphyry potential [Ford, et al, (2015) & USGS (2008)], crustal lineaments [Chernicoff, et. al, (2002)], regional
gravity, regional magnetics, regional and local geology [SegemAR (2023) & Servicio Nacional de Geologia y
Minera (2023)] had been utilised to confirm if the interpretation of alteration and/or mineralisation from the
processed ASTER and Sentinel-2 datasets.
Geological interpretation is then based on the responses displayed in the imagery against known surface
hydrothermal alteration and/or surface geology associated with key mineral deposits. Geological analogues are a
useful tool to delineate similar surface expressions of mineralisation.
Follow-up on the ground exploration activities will be required to confirm the remote sensing interpretation of
the geology.
Sample security
Audits or reviews
•
The measures taken to ensure sample security.
•
Not Applicable for the current ASX Release.
•
The results of any audits or reviews of sampling
techniques and data.
•
No audits or reviews have occurred for either the (i) the processed ASTER and Sentinel-2 datasets or the (ii)
interpretation of the processed ASTER and Sentinel-2 datasets.
