Leach Tank Incident Update

Mwana Africa today provides an update to the Leach Tank Incident at Freda Rebecca Gold Mine (FRGM) reported on Thursday 14 February.

Mwana is pleased to report that all five employees involved in the incident have been discharged from hospital. Four have returned to normal duties, whilst the fifth who was treated for a fractured ankle is reporting as an out patient at the mine clinic.

As a consequence of the incident, effluent discharged into the mine's drainage canal resulted in elevated cyanide levels from normal yellow discharge permit levels to red permit levels. As a result of the swift action taken by mine management under the guidance of General Manager Toindepi Muganyi, discharge levels have subsequently returned to normal operating limits.

Containment of the leach tank contents has been completed and Freda Rebecca management, working in conjunction with the local Environmental Management Agency ("EMA"), continues to monitor discharge levels in the mine drainage canal. The EMA has levied a fine of US$5,000 on Freda Rebecca Gold Mine for discharge of material in breach of its permits. Mine management expects to complete clean up of spillage from the drainage canal by the end of Wednesday 20 February.

The Mines Inspectorate has completed its site investigation and has given permission to start work to remove damaged structures associated with the failure of tank 3. This will then allow mine personnel to commence modifications leading to the recommissioning of leach tank 1 and commencement of repairs to leach tank 2. FRGM is investigating the cause of the tank collapse and assessing the integrity of the other tanks and steelworks.

Production has recommenced on a reduced throughput basis. Production is expected to increase further as tank 1 is brought back on line. Management expect to restore 50% of production levels by the end of February and to maintain this level through March and at present are targeting restoration of full production by the end of March.

It is expected that the incident will in the short term affect production levels and in the medium term affect gold recovery. Management guidance for gold production for the 12 months ending March 2013 is set at 63,000 ozs.

Kalaa Mpinga, Chief Executive Officer of Mwana, commented: "We express our appreciation of the work done by local management in collaboration with Government authorities at the national and local level in dealing quickly and efficiently with the situation. Mwana remains focused on completing the repairs at Freda Rebecca and building on the successes achieved to date at Freda Rebecca."
