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.
Filo del Sol deposit - Geological Analogue (Ausenco Engineering Canada Inc, 2023) (Filo Mining Corp., 2020):
The Filo del Sol deposit has an estimated Total Mineral Resource of 644Mt @ an average grade of 0.31% Cu,
0.32g/t Au, & 10.1 g/t Ag with cut-off grade varying for elements, oxide, sulphide, and AuEq, refer to source
document for the cut-off grade (Ausenco Engineering Canada Inc, 2023). The Filo del Sol deposit is associated with
oxide & sulphide ores that are strongly associated with siliceous alteration (mapped silica and residual quartz),
surrounded by quartz-alunite alteration [refer to Figure 11 of Belararox Limited (ASX: BRX) ASX Release "Porphyry
Prospectivity Confirmed with additional TMT targets identified" dated 18-May-2023].
•The Filo del Sol Cu-Au-Ag deposit has been used as a geological analogue since it shows a similar response to the
siliceous alteration (silica and residual quartz) and similar regional structural features, with N-S major lineament
crosscut by a NW-SE structure [refer to Figure 12 on page 11 of Belararox Limited (ASX: BRX) ASX Release "Porphyry
Prospectivity Confirmed with additional TMT targets identified" dated 18-May-2023].
Valadero Geological Analogue (Holley, 2012)
The Veladero deposit displayed clear links between the ASTER thermal image and the surface-mapped silica /
residual quartz alteration with the final pit predominantly targeting the surface ASTER interpreted Jarosite &
Pyrophyllite [refer to Figure 13 on page 11 Belararox Limited (ASX: BRX) ASX Release "Porphyry Prospectivity
Confirmed with additional TMT targets identified" dated 18-May-2023].
The Veladero surface alteration and mineralisation mapping presented against the final pit design by Holley
(2012) includes silicification, quartz-kaolinite-sulphur, quartz-alunite, quartz-illite, chlorite-epidote, & chlorite-
epidote.
