Operational review

Mimosa had another good year as production remained consistent with steady-state throughput.

The lost-time injury frequency rate deteriorated from 0.26 million man-hours worked in 2013 to 0.38 in 2014. However, it remains a strong performance.

Tonnes milled improved by 3% compared to the previous year to 2.5 million mainly as a result of a 5% improvement in fleet productivities. Both head grade and concentrator recoveries were maintained at 3.92g/t and 77.3% respectively. The operation produced 110 200 ounces of platinum in concentrate, marginally higher than the previous year.

Unit costs decreased by 4% from US$1 782 per platinum ounce in concentrate to US$1 713. In rand terms unit costs increased by 13% to R17 768 as a result of the higher dollar cost and weaker rand/dollar exchange rate.

Discussions with the Government of Zimbabwe with respect to the proposed indigenisation implementation plan are ongoing.

Outlook

Production at Mimosa over the medium term will be determined by the exploitation of the South Hill ore resource through the Wedza Shaft and the existing plant. It is expected that steady-state platinum in concentrate production will be maintained at around 100 000 ounces per annum.
