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].

Unconformity Uranium Drill Targets Identified from 2024 Geophysical Data
Key Highlights
- Final data received and interpretation completed for the ground electromagnetic geophysical surveys from the winter 2024 program at the Marshall and North Millennium projects.
- Several conductive anomalies identified at Marshall, located above and below the unconformity, consistent with regional exploration model.
- Stacked anomalies concurrently with multigenerational geophysical data provides a base to assess the exploration targets and refine drillhole targets.
- The projects are located 15 kilometres from the majority Cameco owned Millennium deposit, and just 40km from the world class McArthur River mine.
- Basin remains funded for the next round of field exploration.
The ground electromagnetic successfully identified 3 main targets which confirms the geological and exploration model. Of note is Target 1 (Figure 1), where modelled EM plates below the unconformity align with a sandstone ZTEM anomaly, which is interpreted to be alteration within sandstone. The identification of these targets is encouraging and consistent with regional trends in the southeastern Athabasca and provides increased confidence in drill hole targeting. Basin is currently reviewing options and priorities of how to progress exploration of these confirmed targets.
Basin’s Managing Director, Pete Moorhouse, commented:
“Conducting ground geophysical surveys on Marshall and North Millennium was a milestone in advancing these underexplored projects in Basin’s uranium portfolio. The form of these anomalies is highly encouraging given the proximity to some of the world’s largest uranium deposits.”
Key results
Following the encouraging conductive anomalism highlighted by the 2023 3D inversion of two historic airborne Electromagnetics (Z‐Tipper Axis) (“ZTEM”) datasets partially covering the current North Millennium and Marshall projects3,4, Basin contracted Discovery International Geophysics5 to carry out ground Stepwise Moving Loop Transient Electromagnetic (‘Ground EM’) surveys on areas of immediate interest within the Projects.
Figure 1 Three main anomalies shown from 2024 ground EM, in plan view (top diagrams) and cross- section looking northeast (bottom diagram). The ground EM anomalies are displayed with the modelled plates against the historical ZTEM data.
The 2024 Ground EM survey data returned six conductive anomaly picks producing three main target areas (Figure 1). The anomalies correlate strongly with the southern edge of the circular ZTEM conductive anomaly at Marshall and the interpreted northern edge of the circular anomaly identified in the historic data. A weaker EM pick was also interpreted centred between the two prominent ZTEM conductivity anomalies.
Three-dimensional modelling using Maxwell produced six electromagnetic conductive plates within the basement stratigraphy, all below the unconformity (Figure 1). The two southeastern plates are clearly aligning with a conductive sandstone ZTEM anomaly identified from the historic data, which is above the interpreted unconformity. This is interpreted as potential basal sandstone alteration proximal to the EM anomalies and constitutes a high-priority drill target area, refer figure 2.

Airborne EM over Multiple Targets on Ti-Tree Project
- Augustus Minerals has contracted UTS Geophysics to conduct a VTEM Max survey over several Copper, Cu-Ni-PGE, Zn-Pb-Ag and Uranium targets along the money Intrusion and within proximity of the prospective 85k long Ti-Tree Shear.
- The surveys will cover:
- The Money Intrusion, prospective for Cu-Ni-PGE mineralisation.
- Copper Ridge and Nics Bore over anomalous Copper Drilling results
- The Coo Creek prospect where drilling by Augustus in 2023 identified strongly anomalous Zn-Pb-Ag mineralisation.
- The Munaballya Well North area which shows potential for economic Uranium mineralisation.
- The surveys will help to advance the untapped potential of the Ti-Tree project to host economic mineralisation of multiple commodities.
Andrew Ford, GM Exploration
“The VTEM survey will provide key targeting data over three highly prospective and different prospects with potential for multiple commodities. Whilst the high prospectivity for copper mineralisation has been well documented, the addition of uranium and Broken Hill base metal style mineralisation highlights the quality of the underexplored Ti-Tree project”.
VTEM
UTS Geophysics has been engaged to conduct a helicopter borne VTEM Max survey comprising 646-line km over three separate survey areas. The system is excellent for locating discrete conductive anomalies as well as mapping lateral and vertical variations in resistivity which helps map structure, alteration and rock type. The system also collects magnetic data through a caesium magnetometer. The transmitter/receiver loop is suspended on a cable approximately 40m below the helicopter (Figure 1).

Figure 2 Prospects and VTEM Survey areas.
Money Intrusion
The Money Intrusion, which has proven potential to host Ni-Cu-Co-PGE (platinum group elements), is part of the regional Mundine Well Dolerite Suite, a regionally extensive dolerite (strike length >80km). This extensive mafic intrusion, which is comprised of a variety of lithologies, including gabbro in the core, olivine dolerite on the chilled lower contact or keel and fine-grained dolerite on the outer edges. Mapping, aeromagnetics and multi-spectral imagery show that the Money Intrusion within the Ti-Tree Project covers a strike length greater than 16km, reaching widths >600m in the north of E09/23241.
