Caesium Pollucite Value ?

This is some information i have been digging up on what the Pollucite is worth,
seems pretty hard to get hard data but we have this

Cabot Corp own and operate Bernic lake which accounts for 80% + of the worlds Pollucite ore
The Caesium is used to make formate brines which are endorsed by companies such as
Chevron, Statoil, Shell, BP, TOTAL, ConocoPhillips, ExxonMobil, Marathon, AgipKCO, Petrobras, Petronas and ONGC
more data at http://www.cabotcorp.com/solutions/products-plus/cesium-formate-brines
and http://www.cabotcorp.nl/solutions/p...e-brines/resources/frequently-asked-questions

Structural integrity of the mining operation at Bernic Lake may be questionable

So if more than 80% of the worlds supply of Pollucite disappears
that remaining 20% isn't going to stretch too far

plenty of talk about it being in demand

Hope some of you can expand on whats here
be good to get some dialog started on this stuff !
