Good point Salvince.
The GBG/Ansteel JV only involves Karara. Any other deposits like Shine and Lodestone are 100% GBG.
Karara is the main game,but with all the infrastructure in place any new deposits are a bonus for GBG.
I can't see why Ansteel wouldn't take any extra ore that GBG can provide or enter JV's to develop large new deposits like Lodestone. They are one of the biggest steel producers in China after all.
