Note that one of the Authors of this paper is John Downs who posts here from time to time as manfromgwelo.  The paper is now dated (2007) but is nevertheless valuable and confirms that pollucite is a valuable commodity, and now PIO have the only commercially operating mine in the world with the potential to prove up a lot more.  Many thanks cammo. This is a valuable contribution to the information available.
