Had to miss the call, but wondered if they discussed if tests are still ongoing with their resin, or if 4 curie level was the highest they could attain? Sounds like 4 curies is sufficient to exceed industry requirements in emerging markets, but that 5 curies + may be needed to demonstrate superiority over traditional processes in the US / Europe.
I was hoping they'd push the envelope even further since they mentioned a couple of months ago that they had plans to scale up even further past the 4 curie level...
