New copper-gold exploration targets have been successfully defined on South Australia’s Yorke Penninsula using technology that reduces exploration costs to a fraction of conventional sampling techniques.
Adelaide Resources Limited managing director Chris Drown said the new technology, referred to as ‘FPXRF’ , has been instrumental in the definition of new geological anomalies near the company’s Alford West copper gold prospect near Moonta.
Mr Drown said the new technology allowed Adelaide Resources to locate and completely delineate a new target zone, called ‘Blue Tongue’, in about one week during December 2013.
FPXRF stands for Field Portable X-Ray Fluorescence , which can be easily and quickly brought to the field to analyse surface soils for concentrations of metals without the need for costly soil sampling and assay processes.
“Our FPXRF survey around the Alford West prospect now comprises in excess of 10,400 samples sites, sampled in 55 man days, for a total cost of $35,000,” he said.
“If we did the survey using conventional soil sampling and assaying techniques, the cost for 10,400 samples would be in excess of $560,000 – and take over 300 days to complete.”
“In Adelaide Resources’ case, has added approximately 2000 strike metres of new drill targets to the FPXRF survey around Alford West, in addition to the 3500 metre long target zone originally defined in a 1970s auger geochemistry program.
Mr Drown said the potential of this new technology is being rapidly recognised by explorers and minerals project developers, as it allows for very detailed results for targeting mineral anomalies.
