Corunna Down new application
Fortescue group of rocks I’m looking at to the SE that long orange zone with the tan colour in between.
This is the new licence Corunna Down following this NE-SE trend of Fortescue Group of rocks.

FG rocks are sedimentary lava flows on top of granite archean greenstone.
Blobs of granite come up through the FG and form pillow lava.
These blobs are full of different minerals.
The tan area Gorge Creek sediments is also formed from volcanic flows and has come up through the FG and folded in a long fold.
FG can contain some gold but mainly zinc, lead and silver.
Copper cobalt nickel and fluoride can be found in quartz veins.
Aluminium and iron can also be found in FG but looks like not this type.
