A picture tells a thousand words...The second image is drill holes over 50m depth, the third over 100m, bottom over 200m.
Look at all that crapy old school RAB drilling. (This is an older exploration drilling method no longer commonly used. Sample quality is less accurate than Air-Core due to the use of a single tube. This means that samples have the risk of contamination through contact with the geology of the drill hole. This is because the sample recovery is outside the drill-string. Air Core drilling is different as the sample is isolated from the geology of the drill hole by the sample tube.)
It was shallow drilling looking for oxide deposits close to the surface. Very little RC or even AC drilling since 2004 and 1999. Almost no DD holes ever.
Given Sandstone is an Orogenic Gold System, one could conclude that the sandstone greenstone belt is almost untouched and vastly under-explored given its geological setting and likely total gold endowment.
