We know it is homogenous. We know where it starts. All drill holes in this area have proven the same thing. They need to define the boundary or extent of the deposit. It is not like PLS,AJM,GXY,KDR etc... You don't need to drill it like swiss cheese to identify the veins, depths, widths within a set area. Homogenous was a huge bonus beyond all others and what they dream of. It is one huge near solid block of pegmatite. Chinese are well aware of what AVZ has. The rest of the world needs to wake up!
P4, P11 AVZ Announcement:
"Drill-holes MO18DD006, MO18DD010 and MO18DD011 are located on section line 6900mN and confirm the continuation of thick pegmatite, see Figure 3, 100m southwest of the intersections achieved by drill-holes situated on section line 7000mN."
"Massive LCT pegmatite" = Massive Lithium-Cesium-Tantalum
