View Disclaimers about the project here


  • Significant copper belt – 26 km trend of copper in soil anomalies and numerous outcropping gossans
  • No systematic exploration between 1990s to 2022 – historical work by Newmont, BHP, MIM; Historical drilling (inc. 20.7m at 0.34% Cu)
  • Overlooked sediment hosted copper system with steeply-dipping, stratiform copper mineralisation (26 km long)
  • 2022 exploration defined three drill ready prospects
  • Several large soil anomalies detected; soil assays up to 1.68% Cu
  • Repeatable rock chip assays ranging 3% to 19% Cu
  • ~1000 km2 land package 360 km from Townville via sealed roads


  • Located in the southern Georgetown Inlier in Northeast Qld
  • Nearby deposits:
    Kidston (5 Moz Au),
    Woolgar (1.9 Moz Au),
    Mount Hogan (Au),
    Kaiser Bill (Cu-Au),
    Balcooma (Cu-Zn),
    Thalanga (Zn-Cu-Pb)
  • Access across tenure via good roads and station tracks (25km from bitumen road)
  • 120km via sealed road to established rail infrastructure
  • Within Yarraman Metals’ 3-tenement ‘Juntala Project’ - PROJ0190
  • Exploration leases granted to Yarraman Metals Late-2021 for 5 years

Geological Setting

  • Numerous copper-rich gossans and outcrops of disseminated chalcopyrite, bornite, chalcocite and malachite within steeply dipping calcsilicate diopside gneiss
  • Mineralisation occurs near the contact with overlying pelitic biotite-sillimanite gneiss
  • Strong copper anomalies (up to 400m wide) detected in soils (up to 0.69% Cu; portable XRF) and termite mound samples (up to 1.68% Cu; Ultrafine) coincident with a 26 km magnetic feature
  • Paleoproterozoic-aged (~1750 Ma) mineral system
  • Sediment-hosted copper system geological similarities to world class provinces (e.g. Zambian Copper Belt, Kupferschiefer)

Extensive 2022 field season defined three drill-ready targets from 2038 XRF analyses, 1195 ultra fine assays, 83 rock chip assays and extensive mapping.

Snake Gossan

  • Identical costean assays, confirming mineralisation continuity at depth
Battle Ridge (discovered in 2022)
  • 300m x 30m soil anomaly (up to 0.69% Cu in soil)
  • Rock chip assays: up to 5.3% Cu, up to 5.33g/t Au, up to 15.2 g/t Ag
Underwood (discovered in 2022)
  • Quartz-baryte gossan containing up 22% chalcocite

➊ Snake Gossan

  • Found by Newmont, 1976
  • Historical drill interval of 20.7 m at 0.34% Cu(including 10.5 m at 0.55% Cu) from 40 m (Newmont, 1978). Identical costean assays
  • Fieldwork in 2022 identified >400 m zone of soils/termite mounds with highly elevated copper values over more than 1.5 km of strike
  • Ultrafine assays identified up to 1.68% copper in the clay fraction from termite mounds
  • Multielement Ultrafine assays confirm and extend historical soil copper and Zinc anomalies
Snake Gossan: Limonitic gossan with boxwork texture after sulphides

➋ Battle Ridge Prospect

  • Discovered in 2022
  • 300 m x 30 m soil anomaly (up to 0.69% Cu in soil)
  • Rock chip assays: up to 5.3% Cu, up to 5.33g/t Au, up to 15.2 g/t Ag
  • Broad area of oxidized calcsilicate gneiss
  • Extensive, disseminated malachite and azurite mineralisation
Oxidised calcsilicate gneiss - 5.3 wt% Cu, 1.35 g/t Au, 3.15 g/t Ag

➌ Underwood Prospect

  • Discovered in 2022
  • Baryte-quartz gossan containing up 22% chalcocite
  • Multiple rock chip assays: 16.3-18.7% Cu, 0.38-0.62g/t Au, 30-34 g/t Ag, 22-32 g/t In
  • Surrounded by a significant soil/termite mound copper anomaly which sits on the regional copper trend
18 wt% Cu (as chalcocite & malachite)
