An old but still very informative article ... sorry, but most of us have not yet recognized the real potential of the sinclair mine:
....The Caesium Formate market is quite unique- so much so that it is difficult to get a complete handle on pricing, however there is some thought that a price of around $25,000 per tonne is not out of the question. That makes the caesium market an extremely boutique market that could be very profitable for an exploration company looking to fund future activities. Should Pioneer be able to work up a modest Resource of say, around 10,000 tonnes of high-grade pollucite, which could yield upwards of 3,000t of Caesium Formate, that could become a very worthwhile project to develop into, what could potentially be, a highly profitable revenue stream.
