Also, the drilling performed by the previous owners stopped at a max. depth of some 500m, while MQR will go much deeper - 1100m for drill hole two which is currently under way, or potentially already finished... (drill hole one was 880m, drill hole three ??m) - this is the depth where we hope to find supersaturated brine...
As I see it, we basically have two options:
1) Li in claystones at surface (this is a pretty sure thing as previous sampling identified good Li grades already) which can be cost effectively bulk mined
2) Li in brine which would be the cherry on the cake (see Albemarle Silver Peak mine just around the corner in Clayton Valley - they have approx 160ppm Li in brine for a 5 to 6kt production pa)
