For what its worth I have some more research to show how AZS compares to PLS. I am interested in responses of a technical nature to the comparison.
The details of PLS comes mainly from quarterly reports. Readers can come to their own conclusions about AZS potential from this information. I chose PLS as its in the Pilbara like AZS.
My main observations relative to AZS are (the second last point is a very interesting observation to consider):
- PLS had lots of pegmatite outcrops but not as many as AZS and PLS were a lot thinner than AZS being up to only 20-30m wide compared to AZS of 100m+ (see 3rd image below)
- in the 13 AZS high priority areas the rock chips are comparable to PLS rock chip grades by grade and average grade (see below for PLS) and PLS did not have any over 4% unlike AZS (I think the maximum was 3.93%)
- The PLS drill intersections images below from 3/16, 9/16 and 12/6 show how the pegmatite spreads under the pegmatite outcrops (see mainly the last and 3rd last image) (PLS outcrops are relatively small in comparison to AZS) - the PLS pegmatites dip at 20 to 60 degrees compared to 10-20 degrees in AZS announcements but that may change as they drill more.
- The intersections (holes 201 to 204) shown by AZS are at depth and don't show how they work down from the surface but they are stacked (ie holes 102 to 204 show 3 stacks) just like those from PLS (see the PLS stacking below in the last 3 images).
- You should also note the width of the pegmatites for PLS under surface vary in width (e.g., from less than 10m to about 50m). PLS had a lot of drill results less than 15m. We don't yet know how that will compare to PLS until AZS drill more holes.
- in addition, in the PLS drill intersections you will notice the spodumene widths are spread across most of the pegmatites ie the spodumene thickness is similar or a bit less than the pegmatite thickness. We do not know yet if this will be the same for AZS but it is possible since outside the coarse spodumene parts of holes 201 to 204, AZS stated these was visible spodumene. If this does happen or AZS then the drill hole thickness will be comparable to PLS and adding the stacks together AZS holes may be thicker. However, given the width of the pegmatite outcrop widths for PLS extent to similar thickness at depth (some are a bit thicker and some less thick as shown in images below), then if the same happens to AZS, as some AZS pegmatite outcrops are much (ie 100m+) wider than PLS, then it is possible the AZS pegmatites from the drill holes will be much thicker than PLS (eg 2-3 times maybe more) - but note that the spodumene may not extend over the width of the pegmatites in the drill holes which is important to this observation. But we won't know until much more drilling is undertaken by AZS.
- can't yet compare drill hole grades with AZS as we don't really have any except the accidental one @1.5% over 7m.
PLS rock chip details - In their 9/14 quarterly they 485 historical rock chips taken from 2002 to 2013 by previous owners. In the northern zone (see image attached) 115 rock chips had an average grade 1.54% while central zone where there was 6+ pegmatite outcrops 104 rock chip (cut-off grade 0.7%) with 78 averaging 2.01% (see image).
