I don't currently hold but have been keeping an eye on BGS and waiting for the JORC reporting to come in. Basically Li is a difficult commodity to model historically as grade and width are difficult to estimate and several deposits i have studied vary probably more than any other commodity.
Most JORC reporting from other companies in this space use to estimate block grade with software in a single pass utilising a three dimensional ordinary kriging approach. Geometry modelling employs variography analysis to identify direction of mineralisation continuity and require a drill hole spacing in the range of 30 x 30m to 80m x 40m for proven and probable. Going from this BGS has a bit more drilling and lab work before a JORC yet to date the lode looks ok IMO.
Have a great weekend all P
