[{"type":"text","content":"\n \n \n \n RNS Number : 4189V\n Rockfire Resources PLC\n 14 April 2021\n \n \n \n 14 April 2021\n Rockfire Resources plc\n (\"Rockfire\" or the \"Company\")Geophysical survey significantly increases Copper Dome target\n \n \n Rockfire Resources plc (LON: ROCK), the gold and base metal exploration company, is pleased to announce that a helicopter-supported geophysical survey has returned a much larger target than originally thought at the Company's 100%-owned Copper Dome porphyry copper project (\"Copper Dome\") in North Queensland, Australia.\n \n Highlights:\n \n \n · A recent geophysical magnetic survey has resulted in high resolution images, with the magnetic data offering a detailed insight into the geology and structure beneath the dome, which had previously not been possible at Copper Dome.\n \n \n · The revised target, based on the new aeromagnetic signature, has increased significantly in area from 1 km x 2 km to a much larger area of 4 km x 3.5 km.\n \n \n · At least three separate intrusions are 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.\n \n \n · Previous drilling had focussed on only one of the three intrusions. Shallow, historical drilling results include 15 m @ 0.9 % Cu, 12 m @ 0.6 % Cu and 24 m @ 0.3 % Cu. Only sporadic gold analysis was done, with a peak gold value of 1.86 g/t Au in drilling.\n \n \n · Abundant structures, including faults (and possibly veins) have been identified, providing a greater understanding of the structural setting for the emplacement of the porphyries.\n \n \n · A three-dimensional interpretation has been commissioned to determine the characteristics of the magnetic response at depth.\n \n \n · Reverse circulation drilling is planned for Copper Dome and quotes are currently being obtained to establish access tracks and for drilling.\n \n \n The following link is a composite image showing the original government aeromagnetic image, the new Reduced to Pole (RTP) image and the new First Vertical Derivative (1VD) image. \n \n http://www.rns-pdf.londonstockexchange.com/rns/4189V_1-2021-4-14.pdf\n \n \n \n \n \n David Price, Chief Executive Officer of Rockfire, comments:\n \n \n \n \"...
