HAD084 Nerdy satellite moment29 Oct 2020 21:37
Brace yourselves / get a drink:
Went to the Greatland website to get the JORC PDF. Page 25 of 26 had the info I wanted - the starting point of the current family favourite - core HAD084.
Did the geodetic conversion to eastings and northerns to get it identified on the Sentinel images and then went through the short history of HAD084 since it first appeared in daylight and radar images, recording when I thought I could see a drill (daylight) or had a radar echo and created this:
Pad prep works 24th June 2020
Drill rig on pad 29th June
No drill 4th July
Drill back 9th July
12th July radar signal (faint)
Drill on pad 14th July
Cloudy image 19th July
24th July radar signal (faint)
Drill on pad 24th July, 29th July, 3rd Aug (faint)
5th Aug radar signal (faint)
Drill gone 8th Aug,
Drill back 13th Aug (faint)
17th Aug radar signal
Drill 18th Aug
Drill gone 23rd Aug, 28th Aug,
29th Aug no radar signal
Drill still gone 2nd Sept, 7th Sept,
10th Sept no radar signal
Drill still gone 12th Sept
Drill back 17th Sept,
22nd Sept radar signal *
Drill on pad 22nd Sept, 27th Sept (double drill?),
4th Oct no radar signal ^
Drill on pad 12th Oct,
16th Oct no radar signal
Drill on pad 17th Oct, 22nd Oct, 27th Oct
28th Oct no radar signal
So, basically it is hard to tell from daylight images if you are seeing a drill at any particular HAV hole or remnants from previous drilling activities - the radar signal is more conclusive. HAD084 they were still definitely drilling on 22nd Sept (* item above) but was gone by the 4th Oct (^ marked item).
So it would seem Newcrest, presumably with all their onsite technology, can get results from cores and into a news release within 5 weeks?
Or they stopped drilling it at its 1876m reported depth in mid-August (17th /18th) before returning to do more a month later (return date the 17th Sept to do another 3 weeks of drilling) in order to go deeper yet? Or to drill a side hole on a different angle?
Phew!
Beer time.
