Tivan and EARTH AI ready drill program at Sandover

  • Further high-grade surface mineralisation discovered at Aileron Station (EL33099) with grades up to 23.8% lead (Pb) returned from surface rock sampling assays, the highest to date.

  • New sampling results have constrained the extent of the mineralised area, supporting a revised drill program plan designed to assess the potential for a polymetallic mineral deposit in the area.

  • Agreement in principle reached with the Central Land Council in respect of a Mineral Exploration Deed, with drill program expected to commence in Q3 2024.

  • New Exploration Licences granted at the Sandover Project.

The Board of Tivan Limited (ASX: TVN) (“Tivan” or the “Company”) is pleased to provide an update of the Company’s 100% owned Sandover Project. Sandover is located 100km north of Alice Springs and covers an area of approximately 8,000km[2] across two contiguous blocks of Exploration Licences and Exploration Licence Applications (14 tenements in total) in the Northern Arunta Pegmatite Province. In March, the Sandover Project was upgraded to a strategic priority at Tivan (see ASX announcement of 27 March 2024).

Galena at Sandover, within improved mineralisation constraints

In recent months, activity at the Sandover Project has largely focused on advancing the high-grade lead and silver prospect at Aileron Station. A soil sample campaign and geological investigation was undertaken to further evaluate the distribution of Pb-Ag mineralisation across the prospect. Assay results have better constrained the mineralisation footprint, defining a 1.75 km x 750 m lead-enriched zone (Figure 2).

==> picture [404 x 272] intentionally omitted <==

Figure 2: Map of soil samples showing improved constraints of lead mineralisation

Primary Pb sulphides (galena) were identified as a result of petrographical studies on rock chips in the area (Figure 3).

Assay results have also better constrained the mineralisation footprint for silver, defining a 2.3 km x 300 m enriched zone (Figure 4).

==> picture [404 x 277] intentionally omitted <==

New highest grade achieved for lead

The on-going geological investigation at Aileron has returned new rock samples depicting a mineralised zone with grades up to 23.8% Pb. This new rock chip assay almost doubles previous known enrichment concentration. The sample was taken within the north-south striking mineralised zone on the western flank of the prospect. The location of the sample is displayed in Figure 5 , in proximity to the prior highest grade results for lead and silver.

A table of new rock chip assay results is provided in Appendix 1 .

Revised drill program

Tivan and EARTH AI had previously designed a drill program to test both the high-grade lead and silver zones at Aileron Station. The new results have sharpened the focus of the program, resulting in changes that target the larger mineralised footprint to investigate the source at depth. Tivan and EARTH AI are working through planning processes with the NT Government and Central Land Council (“CLC”) in respect of these changes.

The revised drill program is shown in Figure 5 .

New Exploration Licences granted

Tivan is also pleased to advise that new Exploration Licences within the Sandover Project have been granted: EL33106, EL33095, EL33096, EL33097 and EL33594.

EL33106 is in close proximity to the Molyhil Tungsten deposit, while licences EL33095, EL33096 and EL33097 are close to the Nolans REE deposit (see Figure 6 ). The location of EL33594 is shown in Figure 1 . The newly granted licenses provide an additional 1,573 km[2] in ground, expanding the Sandover Project to over 5000 km[2] of licensed area under grant.

Reconnaissance geological mapping of the new tenement areas will include a preliminary study involving the deployment of EARTH AI’s proprietary artificial intelligence software to locate potential areas of mineralisation. Field mapping will entail validating the targets generated by the AI software, alongside soil and rock chip survey sampling and detailed geological mapping undertaken by the team at EARTH AI.

This progression of newly prospective exploration areas reflects Tivan’s commitment to the Sandover Project as a strategic priority.

Engagement with Traditional Owners and Native Title Holders

Executive Chairman, Mr Grant Wilson, met with Traditional Owners near Dneiper (EL33105) in June, as part of Tivan’s ongoing commitment to early inclusive engagement with Traditional Owners and Native Title Holders. Further in person meetings are being scheduled for July and August for Dneiper (EL33105) and Aileron (EL33099).

Mr Wilson also met with the CLC in Alice Springs in June. Tivan has reached in principle agreement with the CLC in respect of a Minerals Exploration Deed for the Sandover Project, noting that different forms of land tenure are present across the Project. This deed is the basis for Tivan’s long-term engagement in central Australia and aims to achieve best practices on country.

Upcoming drill campaign and further works

For the upcoming drill campaign EARTH AI will deploy its in-house diamond drill team, prioritising the lead-silver, copper and lithium pegmatite targets across the Sandover Project. Tivan will announce via the ASX platform when the drill campaign commences.

==> picture [596 x 68] intentionally omitted <==

==> picture [596 x 128] intentionally omitted <==

Meanwhile, EARTH AI continues to undertake soil and rock chip surveys to better constrain extents of the surface mineralisation at Aileron. Further soil sampling campaigns aim to constrain areas of lead and silver mineralisation that remain unconstrained, as shown in Figure 7.

==> picture [469 x 332] intentionally omitted <==

Figure 7. Future soil sampling campaigns are designed to further constrain unconstrained areas of lead and silver anomalies

A government co-funded geophysical Induced Polarisation survey will also be undertaken at Aileron (EL33099).

This survey will test the effectiveness of mapping a shallow source body associated with surface lead-silver mineralisation and the potential for identifying a deeper feeder source. The design includes a 50 m station dipoledipole and a 150 m station pole-dipole across the primary target. A single line of 100 m dipole-dipole has also been included over the northern magnetic anomaly.

The design of this survey is shown in Figure 8 .

EARTH AI also plans to conduct additional rock chip and soil surveys at Dneiper (EL33105) focusing on the Li-prospect of highly differentiated pegmatites and Cu-mineralisation of a potential IOCG prospect for the drill program survey to further constrain the target drill areas before commencement.

Comment from Tivan Executive Chairman

Mr Grant Wilson commented:

“Our update today shows the Sandover Project taking shape in practically real time and highlights the differentiated value proposition that EARTH AI has brought through its AI technology and data skills. We are excited to be in the final preparatory stage of what may be a historic drill campaign at Aileron. And we are pleased to be progressing across the entire Project landscape, setting the stage for several years of discovery ahead”.

This announcement has been approved by the Board of the Company.

Geology Deposit type, geological setting, and style of mineralisation. The project is located in the Arunta
Pegmatite Province, in southern-central
Northern Territory, Australia. The
Arunta Pegmatite province is situated
within the Archean to Paleoproterozoic-
aged Arunta Block of the North
Australian Craton. During this time the
Arunta Block experienced multiple
episodes of orogenic deformation and
the formation of granitic intrusions. In
the Mesoproterozoic the Arunta Block
was intruded by a pegmatite swarm
which emplaced into the granitic and
metamorphic hosts. This was followed
by further deformation and
metamorphism during the
Neoproterozoic to Palaeozoic periods
which formed a series of schists,
gneisses, and migmatites. An
extensional tectonic regime in the
Mesozoic caused basins to form,
resulting in the deposition of
sedimentary units. The Arunta Block
was uplifted and exhumed in the
Cenozoic resulting in the formation of
numerous REE rich alluvial deposits.
