I think that Kumba's hand was forced somewhat as well. When the mining rights failed to convert, state took over and can resell them to any other supplier. If KIO did not act in this manner, it means that they tacitly accept the terms of the supply agreement. The risk for them is that whoever now takes over the mineral rights will have the ability to enforce the supply agreement terms on KIO as well (I think this is how it works, but I am just a layman). So from KIO's perspective, irrespective of how the ACL deal goes, they are at least protected from another party entering into this saga and claiming their share of the cost+3% agreement
