Ann: Exceptional Airlift Flow Rates-GPH.AX, page-5

its a good announcement

i have written previously GPH needs to flow at 25 to 30 l/s to produce 100,000tpa

today's announcement states: "airlift yields are strongly indicative but also typically lower than production yields".

GPH have tested during the worst of the dry season (unlike SO4)

SO4 did a change of plan due to flow rates; now planning to also dig trenches

for me, GPH sound conservative (similar to RWD) while AMN and So4 seem to be pushing the envelope

i would say 1/3 production of the others rather than 1/5

smaller land holding; smaller project

nothing wrong with 125,000tpa, imo
