Rockfire Resources plc announced that the Company's recent helicopter geophysical survey has doubled the footprint of potential copper mineralisation at its 100%-owned Copperhead porphyry project in North Queensland, Australia. A helicopter magnetic survey completed in December 2020 has doubled the copper target area at Copperhead. The copper target is now defined by a minimum area of 5 km east-west x 3 km north-south. Faults and fractures are clearly defined and correlate well with known copper mineralisation already discovered in streams, soils, and drilling completed by Carpentaria Exploration in 1972. The drilling in 1972 tested an area less than 0.6% of the expanded target area. The Copperhead target remains open in all directions. The price of copper has increased substantially from USD 4,617 per tonne in March 2020 to USD 7,964 per tonne in December 2020; an increase of 72.5% in the last 9 months. Planned work at Copperhead over the next six months includes detailed prospect-scale mapping and soil/rock sampling within the expanded target area, with subsequent drilling.
