So, the fact that the worlds largest producer/supplier of CsFB Cabot, could only manage $11mill profit 2017 FY from their entire specialty fluids division seems to have been dismissed by some .... which is strange considering CsFB is by far the main game in the CS market .... if the main player can only make $11m from finished product .. then don't expect too much from raw IMO



And its another year on, with the U.S. Geological Survey, Mineral Commodity Summaries for 2018 released in January but it, like those of 2017,16,15 ect ect  ... still paints a rather flaccid picture of the market for CS and CsFB for that mater, and I don't know how anyone can seriously say "a novel and extremely rare commodity" or "the only supply of pollucite in the world" or "PIO have damm near a monopoly" ... that is just pure garbage ....  ramping on steroids as the USGS shows
