SnapshotThe Speewah Fluorite Project hosts one of the largest high-grade fluorite resources globally. Tivan is also evaluating metallurgical grade fluorspar (metspar) (CaF2 content between 85-97%) as a by-product opportunity.

Tivan aims to operate with a low or zero carbon footprint, leveraging hydropower to establish the world’s first fluorite mine powered by renewable energy.

The Environmental Approvals Scoping Study was completed and informed the baseline and technical studies required to support the Environmental Impact Statement for Speewah.

On 9 Dec 2024, Tivan announced the Speewah had been awarded Major Project Status by the Federal government.

Tivan has defined a multi-year pathway to resource expansion at Speewah, that will provide uplift at FS and DFS.

In March 2025, Tivan successfully completed a phase of flotation optimisation testwork for the project.

In May 2025, the Tivan announced it had executed binding agreements with Sumitomo Corp and its subsidiary Japan Fluorite Corporation ("JFC") to establish the incorporated joint venture (IJV) of the project. In parallel, Tivan undertook a corporate restructure, to transfer the project to the joint venture company Fluorite SPV Pty Ltd.

Under the terms of the binding IJV agreements, JFC may invest up to A$60.3M via three tranches for an equity interest of up to 22.5% in the IJV.

In July 2025, Sumitomo reached agreement with JOGMEC under which JOGMEC has become a strategic equity partner in the project through its acquisition of a 49% equity interest in JFC.

In July 2025, JFC made an initial $5.3M equity investment in the IJV for an initial 7.5% equity interest.

17 Nov 2025 - Tivan and ETFS Capital have signed binding agreements. ETFSC is to invest up to $51.3M as an equity interest in Fluorite Holding SPV Pty Ltd, a 100% subsidiary of Tivan, for a 17.5% share of the Project.

Summary:

The Speewah fluorite deposit occurs on the western edge of the Halls Creek Mobile Zone and on the southeast side of the Speewah Dome (folded Early Proterozoic units of the Kimberly Block). The King River Fault forms the eastern margin of the Kimberly Block and consists of a series of intersecting faults. Fluorite mineralisation is predominantly hosted by northnortheast and northeast trending faults within the King River Fault, with minor occurrences along north-trending normal faults within the Speewah Dome.

The Early Proterozoic Valentine Siltstone and Lansdowne Arkose of the Speewah Group host most of the mineralisation and outcrop as linear north-northeast trending ridges. These sediments dip 10 to 20 degrees to the southeast.

Fluorite veins have been mapped in three areas known as the Main Zone, West Zone and Central Zone. In the Main Zone, at least nine vein sets have been mapped over a strike length of 8 km. These contain the strike-continuous A-B-C veins, and the less understood D-E-F-G veins, Cross and South vein sets.

The predominantly white-fluorite mineralisation occurs mainly within tabular steeply dipping veins showing very good strike continuity. The veins range in thickness from 1 to 10 m, often flanked by lower grade stockwork and stringer veins, forming an envelope up to 50 m wide.

Fluorite is associated with quartz-feldspar veining but is younger. It occurs in the various settings previously discussed and listed below:
• Large, persistent veins occupying the main north and northeast trending structures
• Fault breccias and brecciated veins occupying the main structures
• Stockworks and breccias hosted preferentially by the sandstone and to a lesser extent by the dolerites adjacent to the main structures
• En echelon vein sets trending northwest between structures
• En echelon vein sets trending northeast (rare)
• Thin, persistent veinlets following jointing mainly in the siltstones (rare)
• Thin, persistent veinlets following bedding planes in the siltstones (rare)

The larger veins range in true thicknesses of up to 15m and are up to 800m long. They have similar persistence occurrence down dip within the faults and have been intersected in several holes as deep as 400m below the surface, but are only approximately 0.5 m wide at that depth. The stockworks tend to occur adjacent to the main faults and are predominantly hosted by the brittle sandstone unit, although reasonable stockwork veining sometimes occurs in the dolerites. Best fluorite intersections occur where the main north trending faults contain fluorite in the form of veins and breccias, and the adjoining wall rocks (usually hanging wall) contain sandstone-hosted stockwork veining. The en echelon vein systems usually have a lower density of veining than the stockwork and hence a lower fluorite grade globally.

The fluorite veins are younger and crosscut the earlier quartz-feldspar veins. They often form co-axially in the center of the quartz-feldspar veins and as vug fill within them and in the matrix of quartz-feldspar vein breccia. Later carbonate veins crosscut all earlier features. Carbonate and quartz also infill voids in the fluorite veins, and occasionally quartz veinlets cut across fluorite veins.

The fluorite is predominantly green to white in colour, with less common purple-coloured fluorite. In outcrop, it weathers to a grey-white colour. It is generally coarsely crystalline, often with euhedral crystals infilling open spaces. The green-coloured fluorite appears to be younger than the purple variety.
