Elementos (ASX:ELT) has outlined a potential two-stage development pathway for its Cleveland Tin Project in Tasmania, combining its established tin–copper inventory with tungsten and other critical minerals.
At the 2026 Tasmanian Minerals, Manufacturing, and Energy Council Annual Conference, Managing Director Joe David described separate development opportunities based on tin and copper, followed by tungsten and associated minerals.
Cleveland hosts a tin-copper mineral resource estimate of 7.47 million tonnes (Mt) @ 0.75% tin (Sn) and 0.30% copper (Cu). This comprises 6.23Mt classified as indicated and 1.24Mt as inferred.
The project also has a probable ore reserve comprising 3.7Mt of historical tailings @ 0.29% Sn and 0.13% Cu.
The Foleys zone hosts an inferred resource of 8.49Mt @ 0.24% tungsten trioxide (WO₃). Elementos has also defined a conceptual exploration target ranging from 32Mt @ 0.24% WO₃ to 90Mt @ 0.17% WO₃, depending on the cut-off grade applied.
The company cautions that insufficient exploration has been completed to estimate a mineral resource across the exploration target, and further work may not result in one.
Elementos says seven commodities identified at Cleveland appear on at least one critical or strategic minerals list maintained by Australia or allied nations. These comprise tin, copper, tungsten, molybdenum, bismuth, rubidium, and fluorite, also known as fluorspar.
Drilling completed in 2024 identified tungsten, molybdenum, bismuth, rubidium, and fluorine within the same mineralised system. The company says metallurgical programs across laboratories in the UK, Tasmania, and Germany are assessing potential recovery routes for tungsten, molybdenum, bismuth, rubidium, and fluorspar.
Cleveland remains under an exploration licence after the former mining lease was rehabilitated and relinquished around 1991.
The company notes data from a 50 line-kilometre airborne electromagnetic survey completed in June is being processed. The survey covered extensions to the Cleveland stratigraphy and the historical Godkin lead-zinc-silver trend.
Elementos says it plans to compare development scenarios encompassing hard-rock tin and copper mining, tailings reprocessing, the Foleys zone resource, rubidium production, and fluorspar recovery.
Cleveland operated as an underground tin and copper mine over two periods until 1986, producing 23,519 tonnes of tin and 9,691 tonnes of copper from 5.65Mt of ore. Elementos owns 100% of the project.
Elementos is a mining and exploration company focused on developing mature tin and critical mineral assets in Spain and Australia.
