My theory is the fault has caused the northern block to be thrusted down off-setting the displacement of AP12. The AP12 pegmatite extrapolation to surface (2nd image) shows a dip of 38.89° which Azure have specified the dip is closer to 10-20°. Combined with the knowledge of the low dip angles and how the modelled surface (white) coincides with the actual surface (red) (image 1), and that there is a fault present, one theory is that AP12 (labelled pegmatite 1) has been sheared and faulted down to the north and still retains below surface at the expected 10-20° dip in the southern block. With the main mineralised pegmatite labelled as 2 could be the down-dip extension of AP11, and so the main pegmatites (labelled pegmatites 2 & 3) of interest intercepted is potentially AP11 (image 3) and maybe a second stacked pegmatite sheet, or AP11 forks into two pegmatites at depth. Again, just one of many theories.
