Zimbabwean authorities are expected to start retrieving trapped illegal gold miners on Friday but none are expected to have survived flooding in the shafts and the number of casualties could be about 50, State media reported. The accident in Battlefields, 175 km (109 miles) west of Harare, has highlighted the safety issues in illegal gold miners, who last year contributed significantly to the record bullion output of 33 t in the Southern African nation.
