..... and our geo's explanation of this hole, specifically, is...

"Top of hole will be cased (30-60m or whatever can be managed, will be drilling HQ (big core for around 300m), then NQ (medium core size) below this. HQ rods don't bend much so should get down to target depth pretty damn straight. HQ rods act as casing for NQ rods which reduces friction for deeper drilling."

There you go mate.... if you ask the experts you get the right answers!

Cheers, Tony.
