I thought Evans mentioned Reno yesterday. The audio wasn't that great (I couldn't listen with earbuds since I was doing something else at the time), but it sounded like he was saying that they not only figured out how to extract the lithium from clay (to sulfate) but also how to scale this process up. And that they were showing their engineering advances to potential partners but that they were not ready to publicly publish those until mid next year after they have a partnership secured. 

That, particularly the word "scale," sounded like news to me. Or am I just making that entire portion of the webcast up in my wishful-thinking head? :-)
