Ann: Sinclair Mine Complete, First Caesium Shipment Scheduled, page-87

Historically Chinese companies have been unable to meet my requests for the 300 cubic metre (660 metric tonne) volumes of 80% cesium formate brine typically required for use in deep oil/gas well drilling and completion operations (which require heavy clear fluids). If PIO can find a TANCO-sized pollucite deposit then I would imagine that the Chinese owner of JDP and CSF will be banging their door down to tie it up because,  as PIO often note, cesium ore supplies are "constrained"  and oilfield operations are thirsty for cesium formate brine. Drilling with cesium formate brine brings many (many) advantages but there are always brine losses that need to be replaced. So..... come on PIO... get that next round of pollucite exploration underway and become the world's # 1 source of cesium  ore in 2019 and beyond.
