“These results from our maiden soil and rock sampling program at Copper Dome have exceeded our expectations” states Rockfire CEO, David Price.
Summary:
- Rock samples returned maximum grades of 23.4% Cu, 3.2 g/t Au and 952 g/t Ag;
- 23% of all rock samples assay above 0.5 g/t Au, above 5 g/t Ag and above 0.1% Cu;
- High-grade copper, gold and silver rock samples define ridges radiating from the mapped centre of the porphyry system, with potential for high-grade, vein-hosted mineralisation in addition to porphyry-hosted mineralisation;
- Elevated copper-in-soil occurs over a coherent area approximately 500m x 300m, suggesting potential for large tonnage;
- Copper has been found in soils at a new, undrilled location to the north of previous drilling;
- Soil program will be extended to the south to cover second mapped porphyry.
Rockfire Resources plc (LON: ROCK), the London-based, Australia-focused copper and gold resource company, has announced that soil and rock samples collected from the Copper Dome Porphyry Copper Project in Central Queensland have returned rock samples up to 23.4% Cu and significantly elevated copper-in-soil values up to 779 ppm Cu. As announced on 26 November 2018, Rockfire has an option to acquire Copper Dome, which expires on 23 May 2019.
David Price, CEO of Rockfire stated: “The coherent distribution of the copper-in-soil is encouraging for tonnage potential, whilst the copper grades in the soils are almost 80 times background levels.”
“The rock samples have returned extremely high-grade copper and strongly elevated gold and silver in an area to the west of previous drilling. The correlation with topographic ridges provides potential for very high-grade, vein-hosted mineralization, as well as porphyry-style copper/gold targeted by the soil sampling. Previous drilling at Copper Dome was very shallow (some holes only 15m deep), whilst deeper holes intersected 4.58m @ 2.28 % Cu (from 161m) and 3.05m @ 1.24 % Cu (from 54m). These holes were drilled vertically, which may not be the most appropriate orientation if structures are found to be important as fluid pathways and ultimate concentration of copper.”
Commenting on future plans, Price said:
“Our plan is to continue soil sampling towards the south to determine the extent of the copper-in-soil anomalism, which remains open towards the south and east. We will also expand our soil sampling towards the west, to explore the new western areas identified by rock sampling and geological mapping. This expansion of the original program will occur after the field crews have completed ground magnetics at Double Event within the Lighthouse tenement.”
