Belararox Ltd (ASX: BRX) (Belararox or the Company), an advanced mineral explorer focused on high-value clean energy metals, has further characterised six (6) of eleven (11) prospective targets at the Toro- Malambo-Tambo (“TMT”) Project based on ASTER and Sentinenal-2 data and imagery processed by Fathom Geophysics. Independent Technical Consultant, Dr. Steve Garwin, completed the interpretation of the potential for high sulphidation epithermal and porphyry systems.
KEY HIGHLIGHTS
- Field work has commenced in the southern portion of the Toro target, with the mapping of breccias, other rock units, and key features such as mineralisation and alteration.
- Surface sampling has progressed in parallel with mapping activities. The initial focus has been the confirmation of earlier work completed by previous holders of the tenure.
- The preliminary results are under evaluation and appear to align with the geological observations made by previous tenure holders.
- Dr. Steve Garwin has travelled to Argentina to conduct mapping and sampling of specific high- priority targets, collaborating with a field team of local geologists experienced in porphyry exploration techniques.
- Six (6) of the eleven (11) targets generated at the TMT Project from Satellite Aster and Sentinel 2 analysis by Dr. Steve Garwin have undergone further review before heading to Argentina to visit the TMT Project to map and sample selected targets.
- The TMT Project’s targets: Tambo North, Tambo North 2, Tambo VI, Malambo 3, Malambo 4, and Lola Targets have now been characterised in additional detail.
- The targets are interpreted to represent surface expressions of high-sulphidation epithermal and/or porphyry-style mineral systems.
Dr. Steve Garwin arrived in Argentina on the 28th of October, mobilising to the TMT Project soon after arriving in the country. Dr. Steve Garwin will map and sample selected high-priority targets with a field team of in-country Geologists experienced in porphyry exploration methods.
Exploration Director - Argentina, Jason Ward, commented: “The commencement of field work at the TMT Project will focus on geological mapping and systematic geochemical sampling at the porphyry and breccia targets at Toro. This will allow us to have a better understanding of where we are in the system in order to vector in on our target. We shall also investigate some of the targets generated from our remote sensing studies and structural interpretation.”
Belararox’s Managing Director, Arvind Misra, commented: “At TMT Project, our current fieldwork is a major step forward. We’re actively mapping in the southern Toro target, examining breccias, rock formations, and key geological features related to mineralisation and alteration. Dr. Steve Garwin, along with a skilled local team, is spearheading the mapping and sampling efforts. The comprehensive analysis of targets, including Tambo North, Tambo North 2, Tambo VI, Malambo 3, Malambo 4, and Lola Targets, yields valuable insights as they represent surface indicators of high-sulphidation epithermal and porphyry-style mineral systems.”
The TMT project is located in an area where exploration activities have been closing an underexplored gap between [i] the El Indo Metallogenic Belt, which contains the Veladero and Pascua Lima deposits, and (ii] the [Maricunga Metallogenic Belt, which contains the Filo del Sol and Josemaria deposits [refer Figure 1].

ASTER AND SENTINEL-2 SATELLITE SPECTRAL STUDY
The completed remote sensing studies [ (Garwin, 2023.a), (Garwin, 2023.b)] utilised two (2) different multispectral spaceborne datasets [i] Advanced Spaceborne Thermal Emission and Reflection Radiometer (“ASTER”) and [ii] Sentinel-2. 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. 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. Fathom Geophysics (Core & Core, 2023) processed the ASTER and Sentinel-2 data for use in the interpretation of potential mineralisation.
Eleven (11) prospective targets were identified from the satellite spectral imagery with geological interpretation completed on the TMT project by Independent Hydrothermal Systems Specialist Dr Steve Garwin. The 11 prospective targets have been ranked for prospectivity based on spectral response and geological interpretation, resulting in the delineation of prospective targets that show potential for high- sulphidation epithermal mineral systems and/or porphyry-style mineral systems. The selected targets have been ranked for prospectivity across six (6) categories with the A-class category considered to be of higher potential than the B-class; the targets within each class are prioritised from 1 (highest) to 3 (lowest) [refer to Figure 2 on page 3].

Drilling Commenced at Viani in Fiji
HIGHLIGHTS
- The Phase 1, three-hole diamond drilling program has commenced at the Viani Project, Fiji and will test for extensions to the quartz vein gold mineralisation at depth.
- Phase 1 is expected to be completed in early 2025, with plans for additional drilling under the same program dependent on the initial results
- The Viani Project (SPL1513) covers an area of approximately 200km2 and is largely underexplored.
- At the Dakuniba prospect within Viani, low sulphidation epithermal high-grade gold mineralisation has been mapped over >3km strike length.
- Diamond drilling completed by Japan International Cooperation Agency (JICA) in 1995 to 1997 intersected high-grade gold in low sulphidation epithermal quartz veins, including 0.6m @ 27.6 g/t Au.
Alice Queen’s Managing Director, Andrew Buxton said,
With drilling underway, Alice Queen is positioned to test the epithermal gold-style mineralisation identified in historic drilling at the Viani Project. Weather permitting, we anticipate completing the Phase 1, three-hole diamond drilling program in early 2025. Following this, our exploration team will mobilise the drill rig to the Sabeto Project in Fiji to maintain the momentum of this campaign. To deliver timely results to shareholders, we intend to accelerate the analysis of the drill core at ALS Brisbane.”

Details
Geology
The geology of the Viani Project (SPL 1513) comprises olivine basalts and volcaniclastics of the Natewa Volcanic Group which are intruded by andesite sills and dykes. In the 1940s, gold mineralisation was found by local prospectors near the village of Dakuniba. At Dakuniba, low sulphidation style epithermal gold occurs in quartz veins, and silicified rocks along a 3km long NE trending zone.
In 1995-1997, Japan International Cooperation Agency (JICA) drilled six diamond holes at Dakuniba and intersected high-grade gold in chalcedonic, crustiform, colloform banded quartz veins at depths of 50m to 100m below surface (i.e. MJVFV-5 intersected 2.2m @ 11.3 g/t Au, incl 0.6m @ 27.6 g/t Au at 121m downhole). This high-grade gold mineralisation is open in all directions.
Proposed Drill program
The initial Phase 1 drill program at Viani (see Table 1) will comprise three diamond drillholes designed to test continuity to the epithermal gold mineralisation previously intersected in JICA drillhole MJVFV- 5 (2.2m @ 11.3 g/t Au) (see Figure 2). The drilling will test for extensions to the gold mineralisation at depth and along strike.

Maiden Drill Program Set to Commence at the High-Priority Cangallo Porphry Copper Project
- Maiden RC drill program to commence at Cangallo in mid-December
- Program will test a large-scale, undrilled porphyry copper target
- Assay results expected around the end of January 2025
- Permitting underway for drill programs across other high-priority, large-scale porphyry copper targets at Lantana and Playa Kali
Access and drill pad preparations have commenced with drilling scheduled to start around mid-December. The planned program, which comprises a minimum of eight drill-holes for a total of ~2,500m, will take 3 to 4 weeks to complete with assay results expected around the end of January 2025.

Geological mapping and rock-chip sampling has outlined a partially exposed potential copper (+/- gold) porphyry system, within a large-scale (3km x 2km) caldera-like structure containing extensive colluvial and younger sediment cover.
The initial drilling program will test areas containing relatively intense veining (quartz) and porphyritic dykes, where higher copper (up to 0.65% Cu) and gold (up to 0.3g/t Au) values have been found. The possibility of a buried porphyry copper system beneath the extensive cover within the interpreted caldera-like structure will also be tested.
Cangallo is located close to significant infrastructure and is approximately 25km from the town of Chala, and within 10km of the coast.
Commenting on the imminent commencement of drilling at Cangallo, AusQuest’s Managing Director, Graeme Drew, said:
“This is a very exciting time for the Company as we are about to commence the maiden drill program at this high-priority porphyry copper target in Peru which we have been working towards for over 12 months.
Cangallo has never been drilled before and demonstrates classic geochemical and alteration signatures which suggest there is significant potential to discover large-scale copper porphyry mineralisation.
Success at Cangallo has potential to create significant value for our shareholders and we look forward to keeping our shareholders updated as the results become available.”
