Consider this:

These are 60 deg holes from surface which is covered with 2.5m of rubble they say.

Do the high school trig-math and I think you'll find that a 60deg from ground level is 30deg into the ore (assuming its 90deg to surface = perpendicular which it was elsewhere). so, 55m x cos30 =86.6% of 55 = 47m width.

More to the point, if the hole STARTED in mineralisation IT COULDN'T TEST THE WHOLE WIDTH !!.....it needs to start well outside the mineralisation to do that.....

There's more to this yet IMO.
