What's it going to take ?, page-20

From the April 2017 Q report:

During the December Quarter, four 200mm cased boreholes were completed. Three of the holes appear to have intersected the 10 to 15 metre triable sand / sandstone horizon reported in earlier core holes drilled nearby (see Figure 2).
First round test pumping with a 75mm (3 litre/sec) submersible pump showed negligible drawdown of the water table in three of the holes supporting the observation of a transmissive horizon in the holes.
Follow up pumping trials using higher flow pumping equipment were planned for the March Quarter, however this has not been possible due to significant flooding of LD in January which has hampered this planned activity.

My comment: I assume the pump used is rated 3 L/sec and that 3L/s isn't the maximum potential of these bores. Clearly the performance of the aquifer bores is going to be a key factor in updating the PFS to a FS. Perhaps the most important factor.
