Mt Isa East

A district-scale exploration portfolio targeting IOCG and shear-hosted copper and gold systems in one of Australia’s premier mineral provinces.

Large-Scale Copper + Gold Exploration in the Mt Isa Inlier

The Mt Isa East Project comprises approximately 1,300 km² of granted tenure located within the world-class Mt Isa Inlier of northwest Queensland.

The project targets iron oxide copper-gold (IOCG) and shear-hosted Cu ± Au mineral systems across multiple underexplored structural corridors.

Five granted tenements (~1,300 km²), ~30 km SE of Mt Isa, northwest Queensland

Key Prospects

The Mt Isa East Project sits within one of Australia’s most productive base metal provinces, hosting significant copper-gold deposits and operating mines.

Nearby analogues demonstrate strong geological potential for large-scale discovery.

Ardmore North
1,000-1500m RC Drill Program
  • Located near the Fountain Range Fault, a major NE-trending structure prominent in geology and geophysics
  • Coherent surface Cu-Au anomaly over 1.5 km of strike with widespread high-grade rock chips up to 4.49 g/t Au and 14.45% Cu
  • Heritage survey completed (2025)
  • Ground conditions improving; surface works scheduled for June, drill testing July 2026
  • Planned 1,000–1,500m RC drilling program
Grasswren
A compelling geophysical and geochemical target
  • 400×100m Cu-in-soil anomaly overlying a 340m-long steeply dipping VTEM conductor (top of plate at 25m depth, extending ~400m below surface) — geometry consistent with a sulphide body target
  • Environmental approvals for drilling obtained
  • Further mapping underway to refine target with access being determined as a potential drill test in 2026 (results dependent)
Attina
High-grade surface expression with district-scale structural setting
  • Located 5.5 km NE of Carnaby Resources (ASX: CNB) Mt Hope Resource (11.2 Mt @ 1.5% Cu) — same structural corridor
  • Shear-hosted Cu-Au target at the Corella Formation–Overlander Granite contact
  • Two coherent Cu-in-soil anomalies (~300m long each) with coincident high-grade Cu-Au rock chip sampling
  • Best rock chip result across the entire Mt Isa East portfolio: 52.8 g/t Au and 12.35% Cu (sample MER386)
  • Additional gossanous rock chip sample MER163 returned 7.47% Cu; peak soil anomaly 0.4% Cu
  • Further mapping and sampling underway to refine drill targets
  • Reviewing access options for drilling in 2026
