RE: XTR: Racecourse Hole 3, Australia17 Feb 2021 10:13
So what is the current depth of drill 3?
Let's look back:
Drill 1 ( through continuous mineralisation): 213m on Jan7th and 1089m on Jan 20th = 876m in 13 days = 67m per day.
Drill2 ( through continuous mineralisation, with one day lost for mechanical problems): 405m on Jan 28 and 846m on Feb 4th = 441m in 6 drilling days = 73m par day.
So average drill speed for both holes is pretty consistent.
It would therefore be reasonable to take an average of these two figures, i.e. 70m per day ( and we can be pretty sure that there has been no mechanical breakdown on this drill as we were told that this would be immediately reported). So we can say, with some confidence, that over the last 5 days, since mineralisation was encountered, we will now have drilled about 350m through continuing mineralisation.
As has previously been discussed the existing model of the porphyry shows a maximum width of around 250m of mineralisation.
It would seem, therefore, that we have currently found the porphyry to be about 40% wider than previously estimated?
Happy to hear any corrections to my calcs/assumptions, but it certainly looks good from where I am sitting...
