Copper Hill Drilling Update

  • All assays are now available from GCHD469, the first hole in GCR’s current 5000 metre core drilling program
  • Intercepts include 178 metres at 0.26% copper and 0.24g/t gold and 30 metres at 0.26% copper and 0.70g/t gold
  • Encouraging gold values at depth
  • Mineralised breccia fragments indicate deeper porphyry source
  • Drill hole GCHD470 at central Copper Hill completed at 366 metres.

GCHD469 was completed at 894 metres and alteration, zones of brecciation with mineralised breccia clasts, abundant pyrite (potentially gold-bearing) and indications of
copper mineralisation continued almost to end-of-hole.

The hole targeted mineralisation at depth beneath Buckley’s Hill, 750 metres northwest of Copper Hill. It is the deepest hole ever drilled beneath the Copper Hill system and has provided additional information on the nature of the Copper Hill intrusions at depth. Abundant anhydrite veining, base metal-carbonate veining with pyrite and finely
disseminated and veined chalcopyrite were observed from within the mineralised intervals. This porphyry-style mineralisation, along with the additional brecciated quartzvein stockwork zones and the polymict hydrothermal breccia with higher grade gold zones indicates a porphyry source beneath GCHD469.

‘Target Zone’ core sample assays between 480 metres and 894 metres (end-of-hole) have been returned from the ALS laboratory in Orange and results, using a 0.2% copper cut-off grade and maximum internal waste intervals of 10 metres at +0.1% copper, are set out below:
