Geophysical Surveys Could Redefine Tivan’s Critical Minerals Prospects in Northern Territory

Strategic Geophysical Survey Launch

Tivan Limited (ASX, TVN) has announced the commencement of an extensive geophysical survey program at its 100% owned Molyhil Tungsten and Sandover Fluorite Projects in the Northern Territory. The company has appointed Mitre Geophysics, a specialist independent consultancy, to design and oversee the delivery of high-resolution airborne magnetics, radiometric, and ground gravity surveys. This initiative marks a significant step forward in Tivan’s exploration strategy, aiming to sharpen the focus on existing mineralisation and uncover new targets across these critical mineral precincts.

Survey Scope and Technical Approach

The airborne surveys will cover the entire project tenements, including the Walshy’s Wall manganese-barite gossan discovered recently at Sandover. Flying at a low altitude with tight line spacing, the magnetics and radiometric surveys will provide detailed mapping of magnetic susceptibility variations and radiometric signatures, crucial for delineating skarn mineralisation and hydrothermal vein systems. Complementing this, a ground gravity survey at Molyhil will build on a successful 2023 program, exploiting the deposit’s distinct gravity and magnetic anomalies to identify additional tungsten skarn targets.

Project Highlights and Mineral Potential

The Molyhil Tungsten Project boasts a JORC-compliant resource of approximately 4.65 million tonnes grading 0.26% tungsten trioxide, alongside molybdenum credits. Tivan is advancing a scoping study for potential mining and processing operations, with exploration drilling planned to test high-priority targets identified from previous gravity surveys. Meanwhile, the Sandover Fluorite Project has delivered ultra high-grade fluorite intersections, with assays up to 71.7% CaF2, and hosts a newly discovered manganese-barite gossan exhibiting polymetallic signatures including copper, tungsten, and beryllium. These findings underscore the projects’ strategic importance within Australia’s critical minerals landscape.

Implications for Exploration and Development

Results from the surveys are anticipated by mid-Q2 2026 and will directly inform Tivan’s work programs and drilling priorities in the latter half of the year. The enhanced geophysical datasets are expected to improve structural and lithological understanding, enabling more precise drill targeting beneath surface cover. This integrated approach reflects a methodical progression from resource definition to potential development, with due consideration for regulatory approvals and engagement with Traditional Owners and Native Title holders.

Leadership Perspective

Executive Chairman Grant Wilson emphasised the significance of the upcoming field season, noting that the geophysical surveys will be foundational to understanding the region’s mineral systems. He highlighted the abundance of high-quality prospects in close proximity and reaffirmed the company’s commitment to advancing drilling activities starting in March 2026. The strategic focus on critical minerals aligns with broader market demand and Australia’s positioning as a key supplier.
