Ann: Strong Flow Rates from Test Production Bores, page-6

That's very good test pump results over that period of time.

Very confident going forward with these pump results. Seems they are confident that they can even improve on them as well.

Australian Potash Executive Chairman Matt Shackleton said the strong flow test results
meant the Company had now ticked another box on the path to demonstrating the
project’s economic and technical viability.
“We were looking for these test-production sites to produce 14 – 18 litres per second,
which is in line with what the current available research indicates was possible for
palaeochannel systems in the Northern Goldfields. Major Chinese and South American
brine pumping operations achieve flow rates of between 10l/s and 18l/s,” Mr
Shackleton said. These first test-production bores were designed to achieve this rate.
“We were naturally very surprised with the air-lift development yields, which were
achieved using air-injection at pressures of c.2,500kpa (vs. downhole pumps at
pressures of c.1,250kpa). However, by the time the test-production bores were airlifted
as part of their development, the bores’ dimensions (bore diameter, size of the pumps,
screens) were fixed. With the information from this first test-production programme, the
production bore designs will be upgraded in future programs.”
