Strategic Minerals
Dart Mining tenements have demonstrated good propsectivity for several of the strategic minerals (e.g., lithium, tantalum, tungsten, antimony, REEs as outlined in Australia’s Critical Minerals Strategy here
Dart Mining is has a focus on the Dorchap and Glen Wills pegmatite dyke swarms, where intrusions demonstrate Lithium-Caesium-Tantalum (LCT)-style and associated Sn and W mineralisation. Pegmatite dykes are hosted by metamorphosed supracrustal rocks and are typically emplaced during late orogeny along pre-existing structures. Lithium, Cs, Ta, and several other economically important elements and rare earth elements (REEs), including F, Sn, Be, Nb, Rb, and Y, are concentrated in LCT-style pegmatites through fractional crystallisation.
Dart is also focussing on the Walwa and Mt Alfred tinfields, including the McHargs tungsten prospect. Based on the complex structural and intrusive history of this region, the Walwa area is prospective for reduced intrusive related precious–base metal (RIRG) potential comprising tin, gold and tungsten mineralisation, Lithium-Caesium-Tantalum (LCT), and rare earth element (REE) bearing pegmatites.
