Ann: Sinclair Mine Complete, First Caesium Shipment Scheduled, page-104

I suspect that the guidance/insights provided by a combination of soil geochemistry,  ternary radiometrics, an improved understanding of the geology of the Dome pegmatites (from Sinclair) and expert advice from Cabot could make the location of the next pollucite deposit much easier.  The reward for finding a TANCO-sized pollucite deposit would  justify some exploration expenditure in 2019, particularly as the existence of the small Sinclair bleb just mined seems to indicate that the Dome's geological setting was in the Goldilocks zone for pollucite creation. TANCO had some small elongated blebs in the vicinity of the Main Pollucite Zone.
