You are correct. Sorry I made a mistake. Too many numbers floating around on my calcs sheet 3.11g/cc is spodumene weight. Lithium weight is 534kg/m3. Therefore the in ground value is $3.365 USD Billion for 210m of Roche Dure.
I think
total volume Pegmatite x Li % = A
A x weight per m3 = total weight of lithium in t
t of lithium x price/t = In ground Value

(A) being the % of lithium in the pegmatite.
Need to do spread sheet of drill results to work it out accurately.
Ultimately the company will have some 3D computer program to work it out precisely which is far more accurate than my ramblings. But gives us an idea which is better than flying blind!
