Ann: Drilling at the Sinclair Caesium Deposit commences, page-37

This is where PIO were in March 2020 re. their pollucite/caesium exploration strategy :

"So while Pioneer is not prioritizing pollucite exploration beyond the Sinclair Mine, the technical team are highly aware of the pathfinders to look for and remain vigilant for further pollucite discoveries as they continue to explore the Pioneer Dome for further LCT pegmatites.".

And now we have ESS stating :

" A separate pegmatite, PEG007, that lies approximately 1km north of the Sinclair Caesium Deposit has also been identified as a target for caesium and will be drill tested in this programme."

PEG 007 was previously unloved, a very low priority (Cat 1) for lithium exploration.
