Let's flip the question around.
How would you not know a good guess estimate based on their last couple of drilling announcements.
Even an intellectually lacking person like me would have a good clue based on last couple of announcements.
I really wasn't going to be bothered but in my opinion I think you need some help, SO let me assist you @Taurus65 because you have a habit of low content flaming posts for more than 1 year
Genuine goodwill from myself
From 16th April Announcement:
(1) They started drilling on Saturday 14th April
From 20th April Announcement
(2) Drill hole TD 001 was completed on Wednesday 18th April
It took about 4 days to complete
(3) TD-002 - "Drilling is expected to commence on Thursday 19th April."
I would expect it to finish around 23rd April/ 24th April [4 days to finish second hole]
From 23rd April Announcement.
(4) Oh wait HELLO, the company has stated Drill Hole TD 002 commenced and expected to be completed overnight.
Considering it was public holiday yesterday then YES one would have expected an announcement of some sort today or tomorrow and we received an announcement!
Have a nice day
