Ann: Drilling Delivers Further High Grade Lithium at Burmeister, page-60

Counter-intuitively, I'm hoping its not done next week.
Started - yes, but not done.

Seismic requires some effort to place and then retrieve the sensors but in doing this, it gives you an idea what's happening below ground before you choose drilling targets. I have the impression its not like the aerial magnetics where the plane flys over a preset grid and its all done quickly its more akin to soils. You might do an area with a low coverage ratio and then come back with a higher density coverage if it shows promise. I'm guessing here, but a closer sensor grid array may provide a better image of the ground to work with.

If seismic does work well, that would mean TG6 are using it for a while as it is effective in identifying good drill targets. TG6 isn't really going to know how well its working until they complete the loop of putting drill holes into top targets and either hit what they now expect (or hit dusters).
