Silver Sandover Tivan

Latest results sharpen Tivan’s focus for Sandover drilling program

Tivan (ASX:TVN) says new results from a surface rock sampling program at the Sandover Project in the Northern Territory have sharpened the focus of an upcoming drilling program. 

A soil sampling program and geological investigations were conducted to further evaluate the distribution of lead-silver mineralisation across the Aileron Station prospect, within Sandover. 

Tivan, which has a market capitalisation of $111.92 million, reports assay results returned grades up to 23.8% lead, which is the highest result returned to date. 

The results have also better constrained the mineralisation footprint, defining a 1.75km by 750m lead-enriched zone, alongside a 2.3km by 300m silver-enriched zone. 

As a result, changes are being made in the previously designed drilling program, undertaken by Tivan and EARTH AI, that target the larger mineralised footprint to investigate the source at depth. 

EARTH AI plans to deploy its in-house diamond drilling team and prioritise the lead-silver-copper and lithium pegmatites across the project. Tivan will announce when drilling will begin in due course. 

Executive Chairman Grant Wilson says Sandover is taking shape, practically in real time, and shows the differentiated value proposition that EARTH AI brings through its AI technology and data skills. 

“We are excited to be in the final preparatory stages of what may be a historic drill campaign at Aileron,” he says.

“And we are pleased to be progressing across the entire project landscape, setting the stage for several years of discovery ahead.”

Tivan and Earth AI are working through planning processes with the Northern Territory Government and Central Land Council in respect of the changes being made. 

The company has also been granted five new exploration licences within Sandover, providing an additional 1,573km2 of ground, which expands the project to more than 5,000km2 of licenced area. 

Reconnaissance geological mapping of the new areas will include a preliminary study, involving EARTH AI deploying its proprietary AI software to locate potential areas of mineralisation. 

Field mapping will also be carried out to confirm the targets generated by the AI software, as well as soil and rock chip survey sampling and detailed geological mapping. 

Further, Tivan says a government co-funded geophysical induced polarisation survey will be conducted at Aileron to test the effectiveness of mapping a shallow source body, associated with surface lead-silver mineralisation.

The survey will also test the potential for uncovering a deeper feeder source. 

EARTH AI is planning to conduct further rock chip and soil surveys at the Dneiper prospect, focusing on the lithium prospect of differentiated pegmatites and copper mineralisation of a potential iron-oxide copper-gold prospect. 

The survey will be undertaken ahead of drilling to further constrain the target drill areas.
