Butcherbird Copper

Butcherbird Copper


The copper mineralisation at Butcherbird is the focus of early stage exploration with drilling having intersected significant primary sulphide copper mineralisation beneath the historic Butcherbird Copper Mine which produced 8.46 tonnes production grading 30% Cu between 1916 and 1918.

Drilling highlights include:

  • 61m @ 1.96% Cu and 228ppm Co from 113m, including 6m @ 6.08% Cu and 631ppm Co
  • 83m @ 0.43% Cu from 118m including 3m @ 4.15% Cu

The copper mineralisation identified to date is associated with disseminated sulphides including chalcopyrite, primary chalcocite and tetrahedrite associated with a regional scale shear zone to the south of the Yanneri Ridge manganese resource. The mineralisation is open along strike and at depth. The shear is interpreted to be over 10 km in strike.

Geophysical surveys including aeromagnetics and airbourne EM clearly map the shear zone and a ground IP survey has highlighted a number of priority resistivity and chargeability anomalies along and to the north of the target corridor which are targets for first pass RC drilling.
