Sandover Drilling to Test Fluorite Veins with Assays up to 94% CaF2

Tivan Limited has received regulatory clearance to begin drilling at its Sandover Fluorite Project, aiming to unlock high-grade fluorite deposits with assays reaching 94% CaF2. The staged drilling program marks a significant step toward defining a commercially viable resource.

  • Regulatory approval secured for maiden drilling at Sandover Fluorite Project
  • High-grade fluorite assays up to 94% CaF2 from recent surface sampling
  • Stage 1 drilling to commence November with 11 diamond core holes planned
  • Partnership with Sumitomo Corporation to advance project development
  • Additional sampling at Molyhil Project pending assay results in November

Regulatory Green Light for Drilling

Tivan Limited has achieved a critical milestone by securing final regulatory approval from the Northern Territory Department of Lands, Planning and Environment to commence its maiden drilling campaign at the Sandover Fluorite Project. This approval follows the signing of a Mineral Exploration Deed with the Central Land Council, ensuring Traditional Owner consent for site works. The project, located roughly 230km northeast of Alice Springs, is now poised to move from surface exploration to subsurface evaluation.

High-Grade Fluorite Targets Identified

Recent surface sampling and mapping programs have revealed exceptionally high-grade fluorite veins, with calcium fluoride (CaF2) assays reaching up to 94%. These results underscore the potential for a significant fluorite deposit, which Tivan aims to delineate through a carefully staged drilling program. The initial phase will focus on 11 diamond core holes totaling 855 metres, targeting the highest priority veins to assess mineralisation extent and quality.

Strategic Staged Drilling Approach

The drilling program is divided into two stages. Stage 1, commencing in early November, will deliver core samples critical for preliminary metallurgical testing and resource definition. Stage 2, planned for early 2026, will involve reverse circulation drilling to expand the understanding of the deposit based on Stage 1 results. This methodical approach aims to efficiently allocate resources and refine geological models ahead of potential development.

Partnership and Project Development

Tivan’s collaboration with Sumitomo Corporation, a major Japanese trading house and joint venture partner at the Speewah Fluorite Project, adds strategic weight to the Sandover initiative. The companies have signed a Memorandum of Understanding to explore development pathways, including the production of metspar and acid-grade fluorspar. This partnership could accelerate the project’s advancement toward commercial viability.

Broader Exploration and Future Outlook

Alongside Sandover, Tivan has completed additional sampling at the recently acquired Molyhil Tungsten-Molybdenum Project, with assay results expected shortly. These efforts reflect a broader strategy to build a diversified portfolio of critical mineral assets. The upcoming drilling results and metallurgical assessments at Sandover will be pivotal in shaping the company’s next steps and investment appeal.

Bottom Line?

With drilling underway, Tivan is set to transform promising surface results into a defined resource, setting the stage for critical project milestones in 2026.

Questions in the middle?

  • Will the drilling confirm the high-grade fluorite continuity needed for a viable resource?
  • How will metallurgical test results influence the choice between metspar and acid-grade production pathways?
  • What impact will the partnership with Sumitomo have on financing and project development timelines?
