Infinity Mining has discovered a 350m magnetic anomaly beneath historical copper workings at its Coppermine project near Leonora in WA’s Goldfields that the company has identified as a high priority for follow-up RC drilling.
The prospect was highlighted during a recent drone magnetic survey after rock chip sampling earlier this year.
One sample returned 2.06 per cent copper, 3791 parts per million zinc and small traces of gold at 0.33 ppm.
A second adjacent sample recorded 1.56 per cent copper and 1404 ppm zinc.
The company says the anomaly could be associated with buried volcanogenic massive sulphide-style, or “VMS” copper mineralisation, making it a compelling potential target.
The new data provides us with a better picture of what lies beneath the surface at Coppermine. We look forward to drill testing the Coppermine magnetic high target later in 2022.
The Coppermine project is about 5km south-west of Red 5’s four-million-ounce King of the Hills gold mine in an area that contains Archean greenstones.
Archean greenstone belts are known for being one of the more productive sources of gold.
VMS deposits often form in clusters or camps and can be a major source of metals such as copper, lead and zinc and can also produce economic amounts of gold and silver.
Historical rock chip sampling completed by former explorer Pacmin returned results up to 4.6 per cent copper and up to 1969 ppm zinc.
Whilst limited drilling has been carried out on the site, Infinity says two air-core holes previously drilled by Orion were too short and failed to test depth extensions. However, the recently discovered magnetic anomaly has not been tested by any prior drilling.
The Coppermine project is one of eight Infinity holds in its Central Goldfields portfolio within the Leonora gold district.
The company’s recent use of drone technology appears to be paying off after a recent survey revealed multiple targets at its Victor Bore project including some adjacent to historical workings at the site.
The highest-priority magnetic targets at Victor Bore have been selected for further exploration work including auger soil sampling, air-core and RC drilling.
Infinity also has four projects in WA’s Pilbara region — Hillside, Panorama, Tambourah and Noreena Downs — where it is currently testing for gold, copper, nickel and lithium potential.
In June the company confirmed mineralisation of up to 2700-parts-per-million lithium in rock chip assays from pegmatites at its South Tambourah project in the east Pilbara region.
The pegmatites were discovered after a helicopter-supported reconnaissance program in April identified visible spodumene and lepidolite in the southern area of the project.
