"Implats and Aquarius Platinum confirm that a fire occurred at the jointly owned Mimosa operation in Zimbabwe during the night. This was caused when the conveyor belt in the main decline ignited. The fire has been contained," Implats said in a statement.
"All employees have been accounted for and no injuries have been reported. The majority of the workforce was evacuated following the incident. Initially 75 employees were accommodated in refuge bays due to low visibility. They are now in the process of being moved to surface."
Mimosa is wholly owned by Mimosa investments limited, a Mauritius based company held by Impats and Aquarius platinum limited in a 50:50 joint venture.
