StockMarketWire.com - Mining group Rockfire Resources said a helicopter-supported geophysical survey had returned a much larger target than originally thought at its Copper Dome porphyry copper project in Queensland, Australia.
A recent geophysical magnetic survey had resulted in high resolution images, with the magnetic data offering a detailed insight into the geology and structure beneath the dome, the company said.
A revised target, based on the new aeromagnetic signature, had increased significantly in area 4 kilometres times 3.5 kilometres, from 1 kilometre times 2 kilometres previously.
Rockfire said at least three separate intrusions were evident. With one intrusion having been historically drilled and copper found, this adds significant potential for the discovery of copper and gold associated with the additional two intrusions, it added.
IN BRIEF: Rockfire survey returns larger target at Copper Dome project

Rockfire Resources PLC - Australia-focused gold and base metal exploration company - Helicopter-supported geophysical survey returns much larger target than originally thought at the Copper Dome porphyry copper project in North Queensland, Australia. Says the revised target, based on the new aeromagnetic signature, has increased significantly in area to 4 kilometres by 3.5 kilometres from 1 kilometre by 2 kilometres. What is particularly exciting is the identification of what appears to be multiple plumes intruding upwards towards the surface, with only one of these having been drill tested to date. Importantly, the surface geochemistry shows copper anomalism above or proximal to all three intrusions. This provides potential for a much larger mineralised system to be discovered, says Chief Executive David Price.
