Elementos (ASX:ELT) has secured approval for a 3,600m diamond drilling program at its 100%-owned Cleveland Tin Project in northwest Tasmania.
Scheduled to commence in early November 2026, the drilling will target extensions to historically mined tin-copper mineralisation, alongside the project’s tungsten and critical minerals potential.
The program will investigate a previously undrilled corridor between two historically productive tin-copper lenses — the Halls B and Battery lodes — while testing additional tungsten, molybdenum, bismuth, rubidium, and fluorite mineralisation within the Foleys zone tungsten exploration target.
Managing Director Joe David says Elementos’ objective is “to increase the geological confidence, and ultimately, increase the tonnage of our estimated tin, copper, and tungsten mineral resources already estimated at the project”.
“In addition, further confirmation of the previously intersected co-mineralised rubidium, molybdenum, bismuth, and fluorspar, from within the tungsten mineralisation, will go a long way to confirming the future direction of this multi-dimensional project,” David says.
He adds that Cleveland has already displayed “strong evidence of additional mineralisation”, which goes beyond what its mineral resources have estimated.
David also highlights the conceptual Foleys zone exploration target, which ranges from approximately 32 million tonnes (Mt) to 90Mt.
“This drilling program will test both tin and tungsten extensions, whilst also providing important technical data, including geotechnical and metallurgical, to support further technical studies and define the project’s broader development and economic potential,” David says.
The campaign comprises a single primary diamond drill hole extending approximately 1,200m. From this hole, five branched holes will be drilled at different orientations to reduce surface disturbance in the challenging terrain surrounding the historical mine.
The recovered core will support geotechnical assessments and metallurgical test work.
In parallel, the company is evaluating processed data from a 35 line-kilometre SkyTEM airborne electromagnetic survey completed in July 2026 to define prospective conductive anomalies.
The Cleveland Project currently holds an inferred mineral resource of 8.49Mt @ 0.24% tungsten trioxide (WO3) and an exploration target ranging from 32Mt @ 0.24% WO3 to 90Mt @ 0.17% WO3.
It also hosts tin and copper mineral resources of 7.47Mt @ 0.75% tin (Sn) and 0.30% copper (Cu), and tin and copper tailings ore reserves of 3.70Mt @ 0.29% Sn and 0.13% Cu.
Elementos is a tin and critical minerals developer with assets in Spain and Tasmania.
