An interpretation of recent activity by LNR at Lyon based on Sentinel satellite observations.
Transposed sites to Google earth and then to QGIS where multiple possibilities exist for overlaying data.
QGIS image with sites on the LNR plan for the EIS holes.
Some comments about 8 locations 1-8 above.
1 Not certain why this would be drilled. No obvious magnetic or Thorium anomalies. Clearing the area for drilling implies a definite reason for the hole. The Magnetic feature is more a low than a high??
2 The northern site plots on the location of Th anomaly number 8. Part of a peripheral magnetic anomaly.
3 Marginal testing of the Crown anomaly LI-01 in an area of higher magnetics. Multiple RC holes with a central DDH.
The two holes to the NE are centered on local magnetic highs with a (peripheral?) Thorium anomaly
4 and 5 are also on local magnetic highs. 5 is on a possible semi continuous mag high. Possibly drilled at 5 - green triangles.
6 Is in a similar structural position to 1 above. Also shares a subdued magnetic pattern except along the western margin. [Just notice my magnetic anomalies are from earlier work or there is a new interpretation. - only minor for current purposes]. Drilling linear magnetic features and/or testing the 'core' of the mag interp??
To the NE of 6 is the margin of an area of recent ?outwash material that covers the underlying older rocks. This would probably mask any thorium bedrock anomalies and ironstones.
7 Southern EIS hole. Targets southern magnetic margin of LI-03 interp. DDH in centre of an 6 hole RC pattern. Another 4 holes to the east.
Azimuth and dip of hole from this photo - could be 180 degrees out as well.
Hole locations and signs of drilling at all but one site from this time lapse image.
Site prep begins post 15/4 and drilling early May?.
8 Holes to east of LI-03 DDH. Not especially magnetic with tests along the southern margins of interpreted magnetic features.
=========================================
The boring stuff of methods and accuracy.
Access and site prep began in mid April.
Haven't been able to tell which sites are already drilled.
Some "sites" may not be for drilling and the locations of a majority have been eyeballed onto Google Earth when there are good features nearby.
Accuracy hopefully +-100m for all and better than 25m for DDH's and some RC sites.
May not be all sites but those shown are in areas 'cleared' for drilling except a large site to the east which may be the camp.

latest satellite pass 21 May. Link for DYOR if interested.
========================================
LNR are testing a hypothesis and other anomalies with some 10000m of drilling.
WA1 has been mentioned as an example where testing geophysical anomalies has led to SP appreciation.
There are carbonatites in the Lyon River/Gifford creek area.
Not all magnetic features interpreted as carbonatites will be such.
DRE's C6 target and WA1 drilling a Pachapadra (P1, 2 and 4) are two examples where it is back to the drawing board.
High risk High reward as shown by WA1 and CHN among others that 'got lucky' with first holes.
