Twitter, page-2996

Speaking of Twitter, some recent posts there mention Rincon magnesium at uneconomical levels, based on an article which includes the following:

"A common industry axiom says that the ratio of Mg to Li in brines must be below the range of 9:1 or 10:1 to be economical. "

A bit of digging shows that this article is originally from 2010 or earlier:

Now, we all know that the economics of the lithium landscape have changed SIGNIFICANTLY since 2010.
The BG LC price back then was under USD6000/t.

Is it not blatantly obvious that the current pricing landscape renders such old assessments absolutely meaningless?  
It is clear that much higher prices now generally provide for much higher processing costs while maintaining economic viability, in comparison to 8 years ago!   

Perhaps someone with a twitter account could make this concise point to those spouting this nonsense and stating that our economics don't stack up...?
Using an 8-year old generalised economic viability comment as relevant to today's lithium landscape is laughable -  absolutely laughable.
