So if we assume the lithium brine is only below the surface expression of the Salar (extremely pessismistic and improbable).

Surface Area = 2800 hectares

We have depth of brine to at least 100m as per the TEM survey, not sure at full depth, but taking that as a minimum.

As per seimic it could be upto 250-400m.

Depth = 100m

Specific yield I'm going to assume a fairly low 10%, and anything more is upside.

Spec Yield = 10%

Finally, grades at surface were above 140/150 peaking at over 200... Assuming 150 mg/L Li then (with higher grades a bonus)..

Grade = 150 mg/L

Lithium contained estimate = 2800*10000*100*0.1*0.15/1000*5.33 = 223KT LCE

This is taking pretty conservative figures, a more blue sky estimate below:

Width of Aquifer from TEM - 4600M
Length of Aquifer from comments - 8000M (Greenwing noted the northern part of the salar is lower grade, and is affected by hotsprings and such diluting it)
Depth of Aquifer - 200M
Grade - As per TEM, surface resistivity is a bit more so there's some chance we might have higher grades below as these were all surface. 250mg/L
Specific Yield - Keep at 10%, Galan uses 12.5% SY for their sands, highest assumptions are 20% from LEL (which is just not realistic).

Lithium contained estimate = 4600*8000*200*0.1*0.25/1000*5.33 =980KT LCE

Just some napkin maths for when the drill finally begins (if the lifestylers can actually do what they promise). Fairly good potential, but a relatively smaller project, like an Anson, rather than a Galan.

Good effort on the estimate. Who knows until drilling starts.
My issue is with the team running this outfit. They have a long history of failing to deliver including a graphite mine that was never close profitable or near nameplate. Now they want to get into lithium? Better, much safer opportunities out there in lithium.
