The Huntoon Copper Project

The Huntoon Copper Project is a group of five copper prospects at various stages of the exploration pipeline that all lie within a 6 km radius circle centred on the northeastern end of the Huntoon Valley, in Mineral County, Nevada.

The prospects include:

  • M2 – an established resource of 4.3 Mt @ 0.45 % Cu in a skarn setting of diorites and granites/aplites intruding carbonates. M2 is open along strike and down dip, with various defined exploration targets.
  • West Huntoon – 3km2 copper anomaly in soils, with abundant surface showings of copper oxide, overlapping magnetic and chargeability anomalies around a centrally positioned granite cupola outcrop, never recorded before 2023, containing classic porphyry-related fluid release textures. A single drillhole has been drilled at West Huntoon returning 45.7 m @ 0.27% Cu from 35.1 m in hole and 7.62 m @ 0.29% Cu from 138.7 m in hole. This hole was not primarily targeted on copper.
  • M4 – a 2km long zone of anomalous copper in soils above a chargeability anomaly, with surface copper showings at the western end. One of three drillholes under these showings intercepted a mineralised breccia pipe (42.9 m @ 0.23% Cu from 106.22 m). The chargeability anomaly remains undrilled.
  • M5 – a polymetallic system with a large area of anomalous gold, silver and copper in soils which exhibits chalcopyrite stringers at surface, and peak selective grab grades of 1246 g/t Ag and 5.14 g/t Au.
  • Smith Mine – a felsic dyke intruding limestones with a copper oxide halo, with indications of a continuing trend over 1km long.

Key Facts

  • The north end of the Huntoon Valley features a strong concentration of copper prospects.
  • Each of the prospects has features suggesting a large scale magmatic hydrothermal system at work.
  • Porphyry, skarn and epithermal indicators occur at various location accross the prospects.

Exploration

Please refer to the individual pages for details of exploration at each prospect.

The overarching HCP concept was developed in 2023 after the discovery of the Crowne Point granite at the heart of the West Huntoon project. The large intrusions of the area, the Whiskey Flat Granite and the Huntoon Valley Granodiorite were geochemically fingerprinted and found to be fertile for porphyry style mineralisation.

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.
