David Price, chief executive of Rockfire Resources PLC (LON:ROCK), talks Proactive London's Andrew Scott through their recent discovery of high-grade copper in samples at the Copper Dome Porphyry project in Central Queensland.
Price says they've seen grades of up to 23.4% copper, as well as 3.2 grams per tonne gold and 952 grams per tonne silver.
He says sampling will now be extended to the south, to explore a second mapped porphyry.
