Ann: PFS Confirms LD as a Globally Significant SOP Project, page-142

Sorry, this is not a smart a/rhetorical question...I just don't get it....

From the 31st December 2017 quarterly the company states that it has completed 33 days of trench pump testing. At a rate of 8 L/s it drew down 20cm over 33 days. After this test the company increases the pump rate to 10.7 litres per second which results in a drawdown of 33cm and measurable drawdown up to 220m away from the trench edge.

My question is how and why does the PFS refer to 15L/s???

The only place where I can find reference to a rate of 15L/s is in the process water bore field?

At 10.7 litres per second the 2m deep 1km long trench dropped by 33cm. So in five months it's been pumped dry (yes, it will refill of course but at what rate). At 15L/s you could say it will pump dry in no time. Pumping wells/trenches dry can damage them; it's not a good idea.

Anyway, answer me that one with a good simple factual answer please!
