Great Western is building a multi-asset platform across copper, gold, silver, and tungsten in Nevada’s world-renowned Walker Lane Belt, an area recognised as one of the world’s most prospective and mining-friendly jurisdictions. With a 100% interest in multiple claim groups in the state’s prolific Mineral County, the Company is advancing a diversified portfolio of base, precious, and critical minerals aligned with global priorities such as the clean energy transition and the drive for domestic mineral security.

Huntoon Copper Project

A Growing Multi-Mineral Discovery with Porphyry Scale

The Huntoon Copper Project is Great Western’s flagship copper asset, located within a richly mineralised valley system hosting multiple copper prospects within a 6 km radius.

Key Facts

  • West Huntoon: Emerging porphyry system centred on the Crowne Pointe granite

  • M2: Defined JORC-compliant resource: 4.3 Mt @ 0.45% Cu (~19,000 tonnes contained)

  • M4: Copper-oxide and sulphide-bearing breccia zone

  • Yellow Peak:  On trend with West Huntoon; Sierra Nevada staked adjacent claims post our activity

Exploration

Exploration activities are ongoing 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 cornerstone asset in 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.
