Tivan Validates Premium Acidgrade Fluorspar for Speewah with Strong Asian End-User Support

Speewah Product Meets High-Tech Industry Standards

Tivan Limited (ASX:TVN) has taken a significant step forward in its Speewah Fluorite Project by confirming that its acidgrade fluorspar product meets the demanding specifications required for hydrofluoric acid production. Independent assessments by potential end-users in Asia have validated the product's premium quality, highlighting its low impurities such as arsenic, phosphorus, and sulfides; critical for producing ultra-pure hydrofluoric acid used in semiconductor manufacturing and other advanced technologies.

This technical milestone was achieved after sending initial product samples from Speewah to three Asian customers for evaluation. Feedback gathered during meetings in March 2026 was unanimously positive, confirming the product's suitability and enhancing confidence in the project's market potential.

Pilot Program and Marketing Efforts Intensify

Building on this momentum, Tivan is now executing a “mini-pilot” program at ALS Metallurgy in Perth to produce a larger batch of acidgrade fluorspar. This initiative aims to refine the product specification further and support Sumitomo Corporation’s ongoing marketing efforts with potential buyers. The pilot and accompanying variability testwork will underpin the finalisation of the product’s technical parameters ahead of commercialisation.

Tivan’s partnership with Sumitomo Corporation and the Japan Organization for Metals and Energy Security (JOGMEC) remains central to the project’s progress. Together, they operate through Japan Fluorite Corporation (JFC), which holds a term sheet to acquire up to 100% of Speewah’s production, with 80% of that on a take-or-pay basis. The parties are targeting a binding offtake agreement by Q3 2026, which will be a key commercial milestone for the project.

Strategic Partnerships Drive Project Development

Executive Chairman Grant Wilson emphasised the importance of the technical validation and the collaborative relationship with Sumitomo. He noted that the project represents an Australian-first in producing acidgrade fluorspar and could strengthen vital supply chains in Asia. The trust and iterative feedback loop with Sumitomo over the past two years have been instrumental in optimising the project design and product quality.

The Speewah progress complements Tivan’s broader strategic efforts, including recent advances in joint venture talks and exploration activities at other projects. For example, the company is simultaneously advancing its Molyhil Tungsten Project with Sumitomo under an extended Memorandum of Understanding, aiming for a Scoping Study completion by April 2026 and early-stage marketing targeting product delivery in Q3 2026. These parallel developments underscore Tivan’s commitment to expanding its portfolio of critical minerals assets and partnerships.
