A Multi-Mineral Discovery with Porphyry Scale
The Huntoon Copper Project comprises a portfolio of copper prospects across Mineral County, Nevada, centred on the Company's JORC-compliant M2 copper resource. Exploration has identified multiple additional targets, supporting the potential for a larger district-scale mineral system. The combination of an existing resource and further exploration upside positions Huntoon as a key long-term asset within Great Western's Nevada portfolio.
Geology
The geology of the Huntoon Copper Project is that of late paleozoic-mesozoic host rocks (Permian Mina Formation and Jurassic Dunlap Formation) intruded by a dismembered Cretaceous igneous suite comprising weakly peraluminous and weakly adakitic granites, granodiorites and diorites. The most recent phases involve substantial post mineral cover of Tertiary (Cainozoic) volcanic sequences, and recent sediments collecting in tectonic basins. The latter structures have formed as a result of movements on the Mina Deflection, a left lateral transtensional belt which crosses the Walker Lane at a high angle. Tilting relating to these movements have affected the mineralised unit.
Exploration
Exploration activities are designed to refine the geological model and unlock the full scale of the system. With strong copper fundamentals and a compelling geological setting, the Huntoon Copper Project is positioned as a key asset in Great Western’s Nevada portfolio.
