Putting the proposed holes onto the plan view.
Locations scaled from sections look reasonable but won't be super accurate. DYOR
Example of scaling
All holes are planned to be drilled grid S at around -60 degrees and be some 4-500m long (RC with DD tails?). HOles spun around from previous -sometimes works wonders
Additional DDIP lines 1-3 (dashed) and one at the Surprise gravity anomaly.
Some folks have called this a rubbish announcement without giving much, if any reason. Certainly represents a lot of effort in the field and a not insignificant cash outlay. Some of the survey lines were probably visible on satellite imagery so this has been in the works for awhile.
I am not very convinced by the DDIP trend presented. It is parallel to foliation and perhaps bedding but not a very continuous trend.
DDIP03 is on 2 lines and probably extends to the east as a weaker anomaly. Infill line 2 will be interesting to show continuity (or not) in the western Dune area and along the weaker Pokali E IP trend. Dune gravity is partially coincident with Mag distal and deep. The northern planned hole (3N) is sub parallel to 24DD02 and will test a slightly weaker IP high with marginally coincident mag/grav.
DDIP02 is possibly more of a NS anomaly than along the "main" trend. Further north the IP low may reflect some NS structure.
DDIP01 is almost a point anomaly but better supported by deep magnetics and gravity than DDIP2.
IP tests for disseminated sulphides. Higher chargeability higher sulphides. Sulphides can be non economic Pyrite and pyrrhotite (less likely as these tend to be strongly magnetic and that is not the indication for shallow depths). Chalcopyrite (Cpy) combined with pyrite is a likely mix.
3% Chalcopyrite equates to ~1% Cu hence the assays mentioned in the announcement suggest up to 5% sulphides the form of Cpy.
There are more historic holes than those highlighted in the announcement, plus recent holes with pending assays (lime green diamonds).
Focus on the high grade holes in the Ann, plus a "continuous' DDIP trend need to be examined closely to see exactly what they mean.
The IP low at Pokali north has some historic holes with OK grades. Low chargeability (IP low) may mean high resistivity and hence alteration which combined with the gravity high may be a better target than the high IP. Both could be good. Not a geophysicist with access to all data that would help me too much anyway.
I try to remove artificial trend interpretations to see if there are any patterns beyond what is presented. Looks like a broad area with patchy medium chargeability highs including two (to three) very high zones surrounded by lows. Hint of extension to the SE. Line 1 infill will show if the trend in the SW of Pokali extends NW any further,
Is this an arcuate IP anomaly? Faulted in the middle?
Interesting target that hopefully gives some joy to holders.
