Sentinel 1 August and DDH drilling mentioned in quarterly

Sentinel
The "stratigraphic" fence of drilling at McIlroy was extended a further 1.9 Kms to the north. 6 sites at a nominal 320m spacing.
No other evidence of aircore activity in cloud free areas - Emily visible but most of Luni and Green/Joyce are not.
What I assumed to be the DD camp is no longer visible. Probably because the DD rig is soon to be replaced with an RC one.

Link to DYOR - Note there is a tech issue with coverage at Luni/Green.

McIlroy
Gravity

Testing the gravity low and going into the margins. Will give an idea of what lithologies underlie the fence if penetration was sufficient.
37 holes over 10+- days. 31 sites "appearing" in previous 5 days with 6 in the last 5. Which were visited, and when, is a moot point if all have been drilled.
Spacing 160m in south and 320m in north.

Magnetics

Magnetics.
The gravity low is partially reflected in the magnetics which have a little more texture. Marginal features show some linearity not readily visible in gravity.
The 160m spaced drilling was probably designed to test extensions and possible splays of the Elephant Island Fault. Further north are the lows of mag/grav plus some interesting magnetic features.


Couldn't get this image into QGIS accurately enough so the red line is schematic for the fence.

=====================
EIF Stromness drilling.

The quarterly says two holes drilled for 1117m. Sequence not clear but suspect the north hole drilled first. No idea of the length or detail of each hole so shown as 50/50 split drilling north at -60 degrees. There will be some deviation.


Updated schematic image - highly interpretive for Hurley

DYOR as so many assumptions involved in developing this.
