This is a very serious issue, and is not generally being covered by the main stream news.
I have colleagues from the South African mining industry. The above decision, if carried out, will effectively spell the end of inwards investment into South Africa. Last century demonstrated the economic outcomes of decisions just like this, where economic collapse is the outcome. More recent examples include Zimbabwe and Venezuela. More countries at the periphery seem to want to take the same path, which is effectively Marxism, where property is expropriated by the State. The constitution becomes a meaningless document. Free speech is frowned up and then outlawed. Sound familiar?
Bottom line: Any mining or exploration companies in South Africa, including all the South African Gold miners, get out while you still can, and do not think about buying into any company with business interests in South Africa. Last man turn out the lights. They may manage to destroy the country within a few years, if they really try hard enough. Civil war is a likely outcome, based on history.
The only small positive that will come out of this future catastrophe, is metals price increases, via supply destruction. But this will be insignificant, compared to the humanitarian tragedy and future famine, about to unfold. Do not expect much coverage from the main stream media in the West though….what does that tell you?
None of the rocks I hold, have jurisdictional exposure there.
