down dip down structure, page-24

Tas...

Look at the cross-section again...the granite breccia is up to 100m true width in places...they know this from the 5 drills from the west.

Clearly this carries a low grade Cu halo, possibly similar to the apparently parrallel running Dart Fault zone (about 120m further West again), which the same previous 5 holes also intersected.

Now, drilling from the west, whilst intersecting the granite breccia at a reasonable shift from perpendicular, it does not in fact intersect the interpreted high grade zones at an optimum angle...in effect, drilling these lenses almost down-dip.

This for mine is the key to why they would have drillied down dip here.

To gain a decent handle here, they would have needed to drill say 20 or so holes from the west...and even then would likely miss most of the high grade lenses for the simple fact, they would be drilling close to down dip!

I am only postulating here, but it appears to me we have post brecciation slip faulting, which dips to the east, oposite to the actual dip of the main granite breccia...it is these post event slip faults that are likely to be carrying the high grade Cu. The nature of such falting could well see thousands of micro-fractures, all dipping generally to the east...the best way to determine their average impact on grade, wiithin this structurally controlled Cu halo, is to drill down-dip in order to intersect them all with greater meaning.

The alternative would be say 20-50 holes (lol), drilled at say 50 degrees dip, from the east (opposite to the previous 5 diamond holes)...and keep peppering the ore-zone hoping we hit all the high-grade lenses.

So...whilst you might like to scoff at them drilling "down dip" through the low grade halo, in actual fact they are drilling across the high grade zones...and obviously picking up numerous micro-fractures all the way down given the result of the "18" hole, especially after they removed the high-grade Cu lenses from the results.

So, we can now surmise they have a multitude of easterly dipping micro (macro?) fractures, likely minerlised, within a generally westerly dipping granite breccia host.

As I said...this drill makes perfect sense to me...but only as part of a more involved drilling program...a program than can now be more acurately targeted at the zones in question.

Cheers!
