AGO hold 40% of SRR and are not intersted in a take-over.
However,Manganese is an element that is important to steel production,so their investment grows in value.
Recently,SRR surrended all of their non-iron ore interests in the Pilbara to AGO for a poultry sum.
If SRR find significant Commercial quantities of Manganese then AGO,by virtue of their 40% holding, will profit accordingly....no need to buy SRR.
