I emailed ASN early yesterday regarding the Arrowhead report, no reply as yet. Some of the numbers I think Sir Humpfrey Appleby would call courageous.
EG....On page 4 the lithium grade is 100-500ppm, on page 11 lithium product grade is 500ppm.

A product grade of 500ppm with a recovery of 70% gives you a head grade of approx. 700ppm, for 17 years at a reserve of 622million barrels or approx. 90% of the entire site for classic31.

Also a plant throughput of 100,000 barrels per day is 15,900 tonnes of brine per day, a pilot plant is yet to be built so where did that figure come from?

I would certainly like the numbers to be right but I think Sir Humpfrey may be correct.
