Earl Grey to start mining lithium in 2017, page-15

...But how thick is the resource across this 500x 500m area of initial mining for years 1-10 ?

For that we need a cross section of the deposit.   The most recent north/south cross section published recently is shown below and its location represented on the diagram above as a light green line which runs up the middle of the deposit and intersects KGR028 through KGR081.


So given the cross sections location in the deposit its fairly representative of what will be encountered. You would think.
