A comprehensive gravity survey across large parts of the will be carried out alongside passive seismic technique at the most promising targets.
One reason is the size of the licence, which is 1,000 sq km, and the large number of prospective targets it contains.
Gervaise Heddle, chief executive said: “In order to best prioritise exploration across multiple attractive targets, we believe that it is important for Greatland to invest in a comprehensive gravity survey of large portions of the Ernest Giles greenstone belt.
Both gravity and passive seismic surveys are relatively inexpensive compared to full-scale drilling campaigns, he added.
Callum Baxter, chief technical officer, added: “Gravity information combined with passive seismic, airborne magnetics and deep sensing geochemistry will enhance our ability to 'see through' the cover sequences and better direct our drilling efforts.
“Our view remains that the Ernest Giles project has the potential to host several major gold camps and we hope that these surveys will further demonstrate the potential of this vast and virtually unexplored greenstone belt.”
Greatland has so far identified a Western Zone 6km in length and 1.5km in width and an Eastern zone 2km by 1.5km at Ernest Giles.
Several of the zones were up to 60m thick and reasonably shallow.
