Significance of folds is firstly the physical repeat of a unit. A planar horizon which is folded will occupy a greater proportion of the same volume. A single fold (syncline or anticline) within the same volume would contain double the amount of mineralized horizon and therefore a more favorable ore:waste ratio .


Additionally folds happen at all scales, so if its folding with a 500m wavelength there will be a series of much smaller scale folds on each limb (parasitic folds). Each repeat means more ore:waste.


In certain types of fold dilation will occur at the hinge (imagine folding a book in half, at the hinge of the fold there will be gaps between the pages, but the limbs will have no space). This is good so mineralising fluids can move through the strata and ideally deposit metals. Depending on rock rheology there can be a mechanical squeezing of softer units into the hinge as well, if the softer units are what you want they can be good targets.



That is why i like the area to the far west of the EPL. From CLA releases it seem the DOF is a positive topographic feature and highlights the folds well. There may be very good reason why they've not pursued. I went back through the releases and saw one planned hole in this area but couldn't find whether they drilled it and what the results were.



I dont believe there is a single feeder zone due to the consistency of grade/width along strike. There may be multiple zones of increased fluid flow. Personally i believe this is a structural geology solution. Underground sounds expensive. If you can get enough repeats of the DOF into an open pit it might make the numbers better.
