You are exactly right
@Pinkie38.
The pegmatite stringers are the branches of main pegmatite body. Therefore it is actually a good sign that we have found them. Now the new drill holes will try to find the main pegmatite body.
How come people expect to find the main pegmatite body in one drill hole I don't know.
Saprolite clay is not rubbish either. That is the high grade lithium found in the trenches where this drill hole is located.
More holes will be drilled and the pegmatite structure will be understood and the main body will come out.
See Pilbara Mineral's drill plan and outcomes below. When they drill the first hole (PLS-034 at the left upper corner) they only got 5m of pegmatite stringer with a low 0.88% lithium grade. After they drilled more holes to the right side the main pegmatite body came out.
