SnapshotThe Henty Gold Mine in Tasmania is a high grade, underground gold-silver mine with established infrastructure and significant exploration upside in the mineral rich Mt Read Volcanic belt in West Coast Tasmania, proximate to world class deposits.

At the Henty Gold Mine, performance improved throughout the 2024 year driven by investments in equipment and learnings from the Plutonic turnaround. Henty ended 2024 achieving its highest quarterly production under Catalyst’s ownership and the processing plant operating at its 300,000tpa nameplate capacity for the first time since 2008.

In January 2021, Catalyst acquired 100% of the shares and voting rights in Unity Mining Mining Pty Ltd and its 100% owned subsidiary, Henty Gold Mine Pty Ltd (the entity that owned the Henty Gold Mine asset).

On May 19, 2025, Catalyst Metals Limited announced that it has completed the previously announced disposal of the Henty gold mine in Tasmania to Kaiser Reef Limited.

Summary:

Henty is a narrow vein deposit and the mineralised zones of interest occur at depth in fresh rock. The mineralisation generally strikes N-S and has been divided into twelve mining areas. The mineralisation consists of a series of small high-grade lenses of gold mineralisation hosted in quartz-sericite altered volcaniclastic and volcanic rocks that occupy a large sub-vertical quartz-sericite alteration shear zone. Gold is present as both free gold and as gold-rich electrum associated with chalcopyrite and galena in the main mineralised zone. The mineralisation has a shallow plunge to the south.

Henty Mine is a structurally controlled deposit. The Henty Fault is a major structure running NE-SW. Minor multiple faults have been intersected by drilling and underground development.

Mineralization
Mineralisation occurs in the form of pyrite, chalcopyrite, galena, sphalerite, and minor tellurides and bismuth sulpho-salts. High gold grades are associated with intense silicification.

Deposit Style
The oldest rocks in the Red Hills area are rhyodacitic lavas of the MRV, with intercalated black siltstone and shale (correlated with the Central Volcanic Sequence). These volcanic and volcaniclastic sequences are exposed on the eastern limb of an interpreted south - plunging syncline. Massive, quartz-phyric lavas (Mt Julia Rhyolite) and quartz-phyric volcaniclastic sediments, correlated with the Tyndall Group, occur stratigraphically above the CVC rocks in the keel of the interpreted synclinal structure. These younger rocks are also exposed along the overturned western limb of the syncline, truncated by the Henty Fault in proximity to the Henty Mine.

Three deposit types have been identified in the area within the Project.

Stratabound base metal sulphides + gold + silver VMS mineralisation hosted by Central Volcanic Complex (CVC) mass flow units (Lower Mineralised Horizon).

Vein and disseminated copper+gold+magnetite mineralisation associated with chlorite+feldspar alteration of the Red Hills lava. Earliest prospecting and small-scale mining activity concentrated on this type of mineralisation, as at the Northern Adits area.

Structurally controlled, Intrusion-Related Gold (IRG) mineralisation along the Henty Fault at Sterling Valley and Lakeside. This mineralisation has a very strong association with arsenopyrite, with arsenic concentrations above 1% in some instances. IRG mineralization also exhibits a strong correlation with pyrrhotite. Fluids related to an underlying Devonian granite appears to have more influence on the style of mineralisation than at Henty Gold Mine.
