Zambezi: A third Aussie-in-Africa for risk-takers, with the added excitement of being in the exploration phase. Originally listed in London, Zambezi got an ASX listing earlier this month with its 45c shares opening on July 5 at 52.5c and climbing to around 55c now. Interest in the stock will grow as a five-rig drilling program bites into a series of targets in northern Zambia.
