Ann: Exploration update - Nevada Lithium Brine Drilling, page-30

Well I through a few bob in on the punt, and got pretty much as I expected.
I would hate to suggest, but after drilling many thousands of metres, I wouldn't be surprised if they stopped drilling because there is nothing left in the purse. Even with some bad test results surly you would still go for the target.
The whole model was to hit the high conductivity at 850m. If the geology changed at 401m then I doubt there is any geological understanding of the project.

As I posted sometime earlier (before they drilled), its all about the permeability. I asked RCL how they were going to drill, as drill muds can be a killer on permeability testing. I got no clear answer, but was assured Boart Longyear know what they are doing.

The winner here is that Boart may stay solvent a little while longer.
