Ann: GL1-Manna Drilling Intercepts Significant Lithium Pegmatites, page-9

I asked Tom on May 3rd and he said they'd had a lack of Geo's and a rig break down so not much drilling (1 rig) at the beginning of the year. More deep drilling was planned and some RC exploration targets once the staff issues were resolved (Geo's).
They did say there's a rig on standby near Ullarring awaiting the final permit of 8 which was frustrating them with a delay as they have targets ready to drill.
Should be fully cranking by now imo.
