Ann: Quarterly Activities and Cashflow Report, page-61

"I believe that John Downes, the leading world expert on pollucite and all things caesium generally, is currently working for PIO in some capacity, so they will have the best available advice on marketing. "

I totally agree on that, and I believe John would be fully capable of marketing our cesium himself. I would prefer that to getting into bed with some unknown Chinese entity or someone else.
John has been/is marketing Cesium Formate in his own right. He has hundreds of metric tons available for sale right now on his website:
http://formatebrine.com/
So why would we need to go elsewhere if he can do it? Seriously.
