If you look at recent announcements the resource has improved quite a bit. That JORC "measured" area has even higher grade of Lithium
AVZ Drills 209.61m @1.73% Li2O & 954ppm Sn at the Roche Dure Pegmatite
The extra drilling extends the known Li2O% and adds a known quantity to the resource for JORC due in March.
Yes the CR is not great and is likely only happening due to extra drilling. If you look at the drilling performed as to allocated budget it appears to have blown out. Some of those holes are really deep which would require a larger budget. Not one lithium exploration company in Australia has had to drill to these depths with a DD drill. Just look at PLS and the DD holes they drilled. Total 6483m DD with 145,189m RC drilling performed. IMO Nigel's long term play here is to provide a better JORC resource where the real value comes into this.
