Cleveland Project – Tasmania
Cleveland Tin Project – Tasmania
The Cleveland Tin Project is located 80km southwest of Burnie in the mineral-rich northwest region of Tasmania, Australia. The Cleveland mine is a historic (previously operating) underground tin mine still boasting a large Mineral Resource and excellent access to electrical, water and transport infrastructure. Recent drilling has confirmed a large zone of Tungsten mineralisation and a suite of supporting Critical Minerals below the tin and copper Mineral Resources.
Site Location
Cleveland Mineral Resources
Tungsten Mineral Resource
Tungsten Mineral Resource (Foleys Zone, Inferred): 8.49Mt @ 0.24% WO3
Additional Tungsten Exploration Target*: 32Mt – 90Mt @ 0.24% – 0.17% WO3
*The potential quantity and grade of the Exploration Target are conceptual in nature. There has been insufficient exploration to estimate a Mineral Resource within the Exploration Target, and there is no certainty that further exploration will result in the estimation of a Mineral Resource.
Successful Exploration
Cleveland Tin-Tungsten Resource Growth Drilling
Elementos has received approval for a 3,600m diamond drilling program at Cleveland, scheduled to start in early November 2026. The program will test an undrilled tin-copper corridor between the historically productive Halls B and Battery Lodes, and the Foleys Zone tungsten target around the existing Inferred Mineral Resource of 8.49Mt at 0.24% WO3. The core will also feed geotechnical and metallurgical studies supporting a redevelopment pathway for Cleveland. Data from the 35 line-km airborne EM survey completed in July 2026 is being interpreted.

Cleveland Tin Project History
Cleveland Tin Project operated as an underground mine from 1908 – 1917 and more recently by Aberfoyle Resources from 1968 – 1986.
The total ore mined to date is 5.65mt @ 0.68% Sn & 0.28% Cu, producing 23,519t of Sn and 9,691t of Cu. The mine closed in 1986.
Historical workings extend more than 400m below the surface. Mechanised sub-level overhead benching mining method was used. The conventional cassiterite recovery process of gravity followed by flotation was engaged, and the mine benefited from underground and surface infrastructure rehabilitation in1990.
