Yep....thats right...the drill holes are predominantly at 55deg...correct...and perpendicular...or close to...the DOF....SO doesn't that then make the dip of the DOF actually 35deg....going by my cutting edge maths anyhow???
I used 40 deg to be slightly more conservative...BUT...if you used 35deg dip for the DOF...then its length over the 200m vertical depth is 348.7???
Using your above...
6500×5×348.7×2.8 =31.7 mt
As I said..in excess of 30mt...PLUS.
I stand by my previous calcs.
