Ann: Brines Discovered in Maiden Drillhole, page-49

Looks like your on the right track to me. Nothings going to beat actually doing a flow test, But the type of conditions down hole from a diamond rig will be invaluable in getting a handle on this.  I think GXY is doing RC drill and they appear much slower than the diamond hole we drilled. Not what i would expect. . 

I wonder if they use the same experts  (drip under pressure),  I Recon they would all talk any way and with all the work being done in the area i bet they can now deduce more from less as i don't think conditions are going to change that much.

Word of warning - Im a crusty old arsed driller and expert at bugger all and never drilled for brine and i would hate drilling ground like this thou. 
I did like that color change at 273 meters Looks like the brine got a lot more dirty. Lets hope it means  3000ppm Li.  Remember old driller not geologist nor a brine expert. But us drillers recon we know more than a geologist anyway Haha.
