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
“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
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.
