Ultra High-Grade Fluorite assays returned at Sandover
-
Assay results from an extensive surface sampling program at the Sandover Fluorite Project conducted by Tivan in December have returned ultra high-grade fluorite grades with favourable mineralogy.
-
Results from 26 assays measured up to a high-grade of 94% CaF2 (calcium fluorite), with 8 assays from randomly sampled locations returning grades above 80% CaF2. Of importance, none of the 26 assays show incidence of deleterious elements, including arsenic and phosphorus.
-
The results are considered ultra high-grade when compared to global peer resources, as presented in Tivan’s Pre-Feasibility Study for the Speewah Fluorite Project in July 2024.
-
Fluorite is a critical mineral with strategic importance to the global semiconductor industry and rapidly growing use in energy transition sectors, including lithium-ion batteries.
-
Tivan acquired the Sandover Fluorite Project in November 2024 for consideration of $1.075 million, comprised of up-front cash payments, including an initial payment of $400k, and contingent cash payments subject to JORC Resource definition and mineral production. Acquisition completion is expected in February following tenement transfers and stamp duty assessment by the NT government.
-
Tivan has commenced a Sacred Site Clearance Certification process with the Central Land Council and negotiation toward a third Mineral Exploration Deed at the Sandover precinct. Executive Chairman, Mr Grant Wilson, will advance this pathway with the CLC in meetings scheduled for later this month in Alice Springs.
-
In parallel, Tivan will progress development planning through the first half of 2025, including further surface sampling and resource mapping, in support of a drilling campaign later this year.
The Board of Tivan Limited (ASX: TVN) (“Tivan” or the “Company”) is pleased to announce that outstanding assays have been returned from the Sandover Fluorite Project in the Northern Territory. The assays are consistent with the presence of a world-class fluorite deposit, characterised by extensive surface calcium fluorite (CaF2) mineralisation at ultra high-grade of up to 94% CaF2. The mineralogy is favourable for the production of acidgrade fluorspar, with no indication of typical deleterious elements, including arsenic and phosphorus.
The results are an early validation of Tivan’s acquisition of the Sandover Fluorite Project and provide the Company with an optimal pathway to a second fluorite project. Tivan’s extensive review of fluorite prospects in Australia conducted in Q3 2024 (see ASX announcement of 22 November 2024) suggests that Tivan has successfully secured the minerals rights to all of Australia’s known high-grade fluorite.
Surface sampling program and assay results
In late December 2024, Tivan undertook an extensive surface sampling campaign across the Sandover Fluorite Project. Sampling works were conducted via helicopter and entailed landing at several outcropping fluorite reefs where rock chip samples were taken. Sample locations were identified through available historical data and validated in the field by Tivan’s geologists.

==> picture [596 x 127] intentionally omitted <==
Field work confirmed the presence of multiple fluorite rich reefs which were confirmed via assay results from rock chip samples to be ultra-high grade. Samples were taken along a 10km strike length at multiple landing sites, including at the historical “Reef E” (see ASX Announcement of 22 November 2024).
Results from 26 assays returned grades of up to 94% CaF2, with 8 assays from randomly sampled locations returning grades exceeding 80% CaF2, with 10 assays returning grades exceeding 70% CaF2. Sampling techniques are detailed in the JORC Code, 2012 Edition: Table 1 Report enclosed with this announcement. Refer to Figure 1 and Table 1 below for further details on sampling locations and assay results.
The presence of ultra high-grade mineralisation across multiple reefs, observed along significant strike lengths, strongly reinforces the high prospectivity of the area for further fluorite mineralisation. The distribution highlights the potential for an extensive economically viable resource to be defined.
Further, the presence of multiple continuous mineralised zones within the project area provides an opportunity to target high-priority zones while exploring for further extensions of the known mineralisation. These findings not only confirm the significant exploration potential but also contribute to building a comprehensive understanding of the deposit.

Metallurgical findings
The Sandover fluorite rock chip samples display a similar chemical composition to the Speewah Fluorite resource.
In the Sandover samples, the major gangue component for processing is silica, which is typically separable with standard industry flowsheets. The samples have other favourable properties for producing acidgrade fluorspar, which include but are not limited to:
-
Low arsenic, at less than lower limit of 5 ppm
-
Low phosphorous
-
NORMS around or below background levels
-
Low calcite
-
Similar baryte levels to Speewah
The processing solution to recover an acid grade fluorspar product based on information from these rock chip samples is therefore anticipated to be similar to the process flowsheet for the Speewah Fluorite Project. To assess the viability of producing an acid grade fluorspar or metallurgical grade fluorspar from the deposit, metallurgical testwork is required. Tivan will investigate process options and metallurgical testwork programs on samples obtained from future exploration programs.

Pathways with Northern Territory Government
The completion of the acquisition of the Sandover Fluorite Project is currently progressing. Under the terms of the Binding Term Sheet, executed in November 2024, Tivan acquires:
-
Approximately 30% of EL22349 (by way of a new sub-divided tenement - refer to Figure 3).
-
100% of ML33904, MLS79, ML3905, ML33903 and MLS86, which are located within the area of the sub-divided tenement acquired by Tivan.
The new sub-divided Exploration Licence has been defined by the NT Government as EL34050. Stamp duty payable to the Northern Territory Government is $53,212 (4.95% of the total consideration of the acquisition).
Tivan expects to complete the acquisition by late February 2025, including payment of A$100,000 to Thor Energy and Investigator Resources Limited (A$50,000 each) at the completion of title transfer, per the Binding Term Sheet.
In March 2025, Tivan will also apply for the Northern Territory's Geophysics and Drilling Collaborations (GDC) program (Round 18), a competitive grants program funded by the NT Government, to progress exploration activities at the Sandover Fluorite Project. Tivan was awarded two grants in Round 17 of the program in 2024.
Following the completion of resource mapping, Tivan will apply for an Environmental (Mining) Licence in conjunction with progressing all other relevant regulatory processes.

Pathway with Traditional Owners & Native Title Holders
Tivan has commenced engagement with the Central Land Council (“CLC”) regarding the tenement area and exploration scheduling for the year ahead. Executive Chairman, Mr Grant Wilson, will attend planning meetings at the CLC's head office in Alice Springs in late January.
Tivan will work toward securing a Mineral Exploration Deed and Sacred Site Clearance Certificate at the tenement area, building on agreements that were reached with Traditional Owners and Native Title Holders at the nearby Dneiper tenement in November 2024 (see ASX announcement of 21 November 2024).
Tivan remains committed on a firmwide basis to the early inclusion of Traditional Owners and Native Title Holders in project development and to best practices in respect of cultural heritage.
Next Steps - Exploration
Tivan will continue the mapping and surface sampling program during the first half of 2025, with the aim of identifying further new areas of mineralisation. This program will assist in preliminary targeting of prospective areas in the northern belt, estimated at 21kms long, and in the southern belt, estimated at 8kms long. Further infill sampling will be undertaken on prospective areas identified from the results in this announcement, with the aim of refining potential targets for a maiden drilling program during the second half of 2025.
Tivan will keep shareholders informed as the resource definition pathway takes shape.
Comment from Tivan Executive Chairman
Mr Grant Wilson commented:
“The assay results from the Sandover Fluorite Project have far exceeded the bullish expectations Tivan held during our due diligence for the acquisition last year. The extent of the surface mineralisation, the ultra-high grades and the absence of deleterious elements indicate a genuinely Tier 1 global deposit, highly amenable to project development.
Tivan will now leverage the project development capabilities we are building at the Speewah Fluorite Project and the good standing we have achieved with Traditional Owners and Native Title Holders over the past two years to develop a low-risk pathway to resource definition and project delivery. In doing so, we will sequence our entry into offtake markets in Asia in close collaboration with our proposed joint venture partner, Sumitomo Corporation.
With the valuation framework recently achieved at Speewah, and the structural scarcity and criticality of high-grade Fluorspar in Asia, Tivan is now in a commanding position to build a company of strategic importance across northern Australia.”

| • | The reefs are exposed in two southeasterly trending belts | |||
| on the northern and southern side of the Elyuah Range. | ||||
| These belts contain several reefs striking in an easterly to | ||||
| east-southeasterly direction. The distance between the | ||||
| two belts at the western end is 4 km, increasing gradually | ||||
| in an easterly direction. The Elyuah Range consists of | ||||
| Upper Proterozoic to Lower Cambrian sediments | ||||
| synclincally folded (limbs dipping 20o) and pitching gently | ||||
| south eastward. • The northern belt of fluorite | ||||
| mineralisation is 21 km in length. It contains the Narbarloo | ||||
| stockworks at the western end together with at least 16 | ||||
| separate veins of various sizes, including reefs A to H | ||||
| some 10 km to the eastward. Strike directions vary | ||||
| between north-west, north-east and east-southeasterly. | ||||
| • | The southern belt is 8 km in length, trends east-south- | |||
| easterly and contains five known separate quartz fluorite | ||||
| reeds or stockworks confined to a zone less than 600 m | ||||
| wide. Strike of the individual veins is irregular. • The | ||||
| dimensions and grades of the reefs vary between quartz | ||||
| and fluorite reefs from 3 to 1800 m in length and from 0.1 | ||||
| to 8 m in width. The granite host passes beneath the | ||||
| surface drift and alluvium of Thring Creek in an easterly | ||||
| direction. • The fluorite-quartz reefs in the Narbarloo | ||||
| locality are situated 1.6 km north-west and 3 km south of | ||||
| Grant Bluff. The Narbarloo Reefs form the western-most | ||||
| mineralisation of the northern mineralised belt where the | ||||
| vein structure of these reefs could be classed as multiple | ||||
| cymoid loops which in the vicinity of the reef intersections | ||||
| tend to form open stockworks approximately 8 m across. | ||||
