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.

Successful Exploration

Drilling of Shallow Copper, Gold & Silver Drill Target The company identified a significant and shallow gold, copper, silver and zinc target at Cleveland from an electromagnetic downhole (DHEM) survey which followed the 2024 drilling program in December. On 14 March 2025, the company announced that it had commenced drilling of the shallow copper, gold, silver target.

The drilling program is underway and plans for three ~200m drill holes that will test for extensions to the high-grade copper-gold intersection recovered in hole C2123 in 2024.

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.
