Belararox Advances Toro South with MT/IP Surveys, Drilling Imminent
Belararox Limited has initiated advanced geophysical surveys at its Toro South target in Argentina, setting the stage for drilling in late 2025. Age dating confirms geological similarities to major copper systems, enhancing the project's appeal.
- MT/IP geophysical surveys underway to refine drill targets
- Drill contract negotiations nearing completion with mobilisation planned for November
- Age dating confirms magmatic ages consistent with major copper porphyry systems
- Surface sampling and 3D modelling support significant copper porphyry and epithermal potential
- Project located near major regional faults and close to ATEX Resources’ Valeriano deposit
Exploration Momentum Builds at Toro South
Belararox Limited has taken a significant step forward in its exploration program at the Toro South target, part of the broader Toro-Malambo-Tambo (TMT) project in Argentina’s San Juan Province. The company has commenced combined magnetotellurics (MT) and induced polarisation (IP) geophysical surveys designed to image subsurface resistivity anomalies down to depths exceeding 2,000 metres. These surveys are critical for honing in on high-priority drill targets ahead of planned drilling in the fourth quarter of 2025.
The use of MT/IP surveys is a proven technique in copper porphyry exploration globally, with notable success at nearby projects such as ATEX Resources’ Valeriano deposit, which boasts a substantial mineral resource estimate. By deploying these advanced geophysical tools, Belararox aims to delineate the most prospective zones within what it believes to be a large, fertile mineralised system.
Geological Foundations Strengthened by Age Dating
Complementing the geophysical work, recent age dating of intrusive rocks from Toro and Tambo South has confirmed magmatic ages between approximately 25 and 19 million years. These ages align closely with those of major copper porphyry systems in the Vicuña Belt, including the Josemaria and Filo del Sol deposits. This temporal correlation bolsters confidence in the prospectivity of the Toro South target to host significant copper mineralisation.
Surface rock sampling has yielded encouraging assay results, with copper grades reaching up to 1.41%, alongside notable gold, silver, zinc, and lead values. Three-dimensional geochemical modelling further supports the presence of a substantial copper porphyry system at depth, with indications of an overlying epithermal mineralisation zone. These findings provide a compelling geological framework for the upcoming drilling campaign.
Drilling Plans and Strategic Positioning
Belararox is in the final stages of securing a drilling contract with a global industry leader, with mobilisation to site scheduled for late November 2025. This readiness underscores the company’s commitment to advancing exploration efficiently and capitalising on the project’s potential.
Strategically, the TMT project occupies a prime location at the intersection of major regional faults and lies just 20 kilometres southeast of ATEX Resources’ Valeriano project, which recently attracted a US$40 million strategic investment from Agnico Eagle Mines Limited. This proximity to established copper resources and infrastructure adds an additional layer of appeal to Belararox’s exploration efforts.
Looking Ahead
As the MT/IP surveys progress and drilling approaches, the market will be watching closely for results that could validate the geological promise of Toro South. The combination of advanced geophysical data, robust geochronological evidence, and encouraging surface geochemistry positions Belararox to potentially unlock a significant copper discovery in one of Argentina’s most exciting copper provinces.
Bottom Line?
With drilling imminent and geophysical data shaping targets, Belararox’s next moves could redefine its standing in Argentina’s copper landscape.
Questions in the middle?
- How will MT/IP survey results influence final drill hole locations and priorities?
- What scale and grade might initial drilling at Toro South reveal about the deposit’s potential?
- Could the proximity to Valeriano and similar magmatic ages translate into comparable resource size or quality?
