Porphyry Prospectivity Confirmed With Additional TMT Targets Identified

Belararox Ltd (ASX: BRX)(Belararox or the Company), an advanced mineral explorer focused on high-value clean energy metals, has identified 11 prospective targets based on satellite spectral imagery processed by Fathom Geophysics and the geological interpretation completed on the Toro- Malambo-Tambo (“TMT”) project by Independent Hydrothermal Systems Specialist, Dr Steve Garwin.


Key Highlights

  • A Satellite Aster and Sentinel 2 study at the Toro, Malambo and Tambo project confirms hydrothermal alteration.
  • Eleven prospective targets have been identified.
  • The targets are likely to represent surface expressions of high-sulphidation epithermal and/or porphyry-style mineral systems.
  • Targets have been ranked for prospectivity based on spectral imagery and geological interpretation.
  • The high-priority targets show similar spectral characteristics to observed hydrothermal alteration and silicification at Filo del Sol.
  • Additional targets are being considered for an expanded exploration program for the TMT project.

The TMT project is located in an area where exploration activities have been closing the underexplored gap between the [i] El Indo Metallogenic Belt, which contains the Veladero and Pascua Lima deposits, and the [ii] Maricunga Metallogenic Belt, which contains the Filo del Sol and Josemaria deposits [refer to Figure 1]. Hydrothermal alteration has been used as a vector for deposits in the region [refer to Figure 15 on page 17].

Chief Technical Consultant - Argentina, Jason Ward, commented:

“This satellite spectral study has confirmed the presence of hydrothermal alteration at the three main targets at Toro, Malambo and Tambo, and also identified eight additional target areas. We look forward to following up these targets with geological mapping and sampling once our Environmental Permits are granted”.

Belararox’s Managing Director, Arvind Misra, commented:

“When we first acquired the TMT Project, I said how delighted I was as we expected it to enable BRX to pursue exploration activities in a highly prospective region in Argentina. While we still have a way to go, the identification of 11 prospective targets with surface expressions is a strong first step in the TMT Project meeting our expectations”.

ASTER and Sentinel-2 Satellite Spectral Study – Rationale for Targeting

The study (Garwin, 2023) 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 study.

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].

Australian Organisations Make Case for Natural Capital Accounting in Resource Sector

Two organisations have collaborated on the release of a new suite of resources geared at helping companies in the Australian mining industry implement natural capital accounting (NCA).

The Cooperative Research Centre for Transformations in Mining Economies (CRC TiME) and CSIRO, Australia’s national science agency, announced the news in a press release on Monday (July 15).

NCA is a means of “accounting for impacts on nature over the life of projects.” Mining companies of all stages are increasingly being asked to show how they affect the environment and mitigate their impact accordingly.
