A lot depends on the ground,the depth of the holes, and the type of drill they use. ,how much air pressure they have.. if the ground is broken or hard.... quiet a lot in it really... but i would assume they will use an RC drill (reverse circulation)type which would mean they will get aprox 200m per day depending on rod changes and hole depth perhaps - that is all going good. (might be out here as i have little knowledge on drilling IO ground - only base metals which is generally softer) Anyone else got info or thoughts on this?

Will be nice to see the results... perhaps Chimmy99 can take some photos of the holes as this will give you an indication on what they have passed through (refer earlier presentation which shows material after drilling on the ground)
