Well as we know Albemarle have upped the offer to $3, crazy IMHO, but it's their money.
Word is they and IGO are hoping Tianqi keeps having issues so the Chinese will sell cheap. When the Chinese toe cutters came in Feb, they undid all the work to fix their original design and said that perseverance would win. Probably will...eventually...but Albemarle and IGO will be hoping for a cheap deal if they give up on the processing arm.
So for anyone thinking Lithium is on the want....U$4.5bn says otherwise.
