Updating the above post with some extra grid lines and site interpretations to 6/8.
This eastern extension was begun by 1/8 and is probably still a work in progress.
Why do it now before Emily which was "announced" as the next target last month?
- Rig on site nearby is one reason though not an obvious one for this level of activity. Likely to be more than this.
- Wide spaced lines with little obvious focus. Perhaps more detail at north end of 18 hole line and perhaps "infill" on the line "in progress". Overall pattern suggests exploration of "stratigraphy" with a drill rig.
- Some interesting observations in the McIlroy fence. Possible though the geophysics doesn't indicate strong E-W structures in the south.
- As with Steller a new target generated based on mag/gravity? If magnetics I suspect E-W lines would be more appropriate locally.
- Speculations only. Hopefully a positive announcement later this month....
- Assuming holes go to the bedrock interface then a lot of data can be gleaned from logging and lithogeochemistry from EOH near EOH samples. Maybe some goodies there or on the way down.
Magnetics
Detail of the recent interpreted drilling area - mag
[Different levels of resolution apparent plus exposes minor problem with georeferencing images]
Strong NS magnetics in the east.
Complex in the west with trends almost at right angles (near EW) plus linear mag lows (?faults)
Best to drill NS or EW fences? Perhaps a combination with EW in the east. Depends on targets with linear magnetics probably not related to carbonatites.
Gravity
Gravity supports NS drilling better than magnetics IMO. There is a weak correlation between mag and grav for a NS trend at the east end of interp drilling. The baseline extensions may be used to test here in the future.

Source imagery is not too clear but will add. Lines are subtle and barely visible on this. Individual site activity is often difficult to spot even with detail and time lapse.
With data as tricky as this I often take a screen shot and annotate before transposing to Google Earth.
If the hole spacing is uniform then sites can be scaled onto GE. Not really concerned to give perfect locations. Reasonable and schematic with ?marks to show where might be more problematic. These sites will not be very accurate but the line extents are good IMO.
