looking at the drilling reports, prior to the stratigraphic depth changes on the 24th-25th, the stokes siltstone was assumed to be only approx 100m in depth.
current drill reports have changed the stokes to 300m.
could it be that because they are 50-60m into the stokes, going by the old drill reports, they may only be 40-50m from the top of the stairway?
they may well just be taking it cautiously and 'searching' for the top of the stairway so they can change the drilling technique to suit.
from the last jh presentation, there is potentially $135m riding on this hole, they don't want to mess it up. what's a week or two when you have to get it right?
hardness of the rock has caused drilling issues in the mereenie, but this far into the siltstone, a much softer rock, shouldn't cause the drilling issues previously encountered - unless the silicification has migrated down through the siltstone.
hopefully find out in tomorrows' drill report.
