I think you are confusing Ivanhoe Australia with Ivanhoe Mines.
The article is about Ivanhoe Australia appointing 2 new directors and whether that is a sign they want to split from Ivanhoe Mines.
It has nothing to do with what Ivanhoe Australia plan to do with their stake in EXS. In fact, the article actually mentions that Ivanhoe Mines are still keen to keep a hold on the Cloncurry assets of Ivanhoe Australia.
