The share prices of Australian-listed miners with operations in Zimbabwe received a boost on reports that Zimbabwean president Robert Mugabe had been defeated in the country's recent elections. Platinum producer Zimplats, which has operations in the country rose to its highest point in more than six months. Even the impact of higher platinum prices through the first quarter of this calendar year prompted less of a price spike. But management has wised to this, issuing a statement to the ASX that there appeared to be speculation in the company's share price based on the election results. Zimplats advises shareholders to continue to exercise caution in share dealings due the uncertain conditions prevailing in Zimbabwe. In the wake of the election, followers of Mr Mugabe have begun an intimidation campaign in rural areas against opposition supporters.
