exploration update dso hematite and gold

The update confirms previous announcements by Gondwana about the commencement of drilling campaigns at Parker Range and Corunna Downs for gold and DSO iron-ore respectively.
New info' that is welcome includes a detailed gravity survey instead of an aero magnetic survey which indicates Gondwana is following the lead by Atlas at Pardoo.
The difference from what I can work out is that the detailed gravity survey advances the identification of the hematite as it is "terrain corrected", which I guess gives a better ability to interpret the data for the direct shipping iron-ore for the drilling targets and is more efficient in the data it provides.
I'll have a look at the Atlas Pardoo gravity survey for comparisons.
By the sounds of it, Gondwana appear pretty confident of success.
