Zimplats, Zimbabwe

Zimplats’ focus this year remained on its ongoing expansion programme.

Output of platinum in matte increased marginally year-on-year as the operation geared itself for the ramp-up in production in the coming year. Open-pit mining, which had already been scaled back because of high costs, was finally halted in November 2008 in response to the slump in metal prices. Underground production from Portal 2 was ramped up to maintain production levels. The open-pit orebody continues to provide optionality should the market environment demand fast access to additional ore in the future.

The Phase 1 expansion, a $340 million project involving the development of two underground mines, Portal 1 and Portal 4, a new concentrator and other infrastructure, is on track. Portal 1 reached full production in December 2008 (1 million tonnes a year), and Portal 4 is scheduled to reach this milestone in 2011 (2 million tonnes a year). The concentrator, was commissioned in July 2009 and should reach its full production capacity of 2 million tonnes per annum in October 2009.

In the wake of the dramatic decline in metal prices and the dollarisation of the Zimbabwean economy, both operating costs and capital expenditure were reviewed during the period with a view to minimising debt and conserving cash. Unit costs were negatively impacted by the increase in overhead costs as the operation prepared for ramp-up to full production in the coming year. Once this is achieved, Zimplats will become one of the lowest-cost primary producers in the world.

The issue around the mobility and loss of skills has to a large extent been addressed and is less of a problem for the operation than a year ago. Zimplats is now focusing on training, particularly of new teams as the ramp-up takes effect. Food is also more freely available locally, whilst a pro-active approach to the health and well-being of employees has protected them from the recent cholera crisis in the country.

Outlook

In the coming year, the completion of the Phase 1 expansion will result in production increasing to approximately 4.2 million milled tonnes per annum. Steady-state output of 180 000 platinum ounces will be achieved during FY2010.

Unit costs are expected to decline on the back of the increased volumes (milling of tonne stockpiles). Thereafter, management will focus on mining efficiencies in order to contain cost increases.

Future growth at Zimplats depends on economic and political stability in Zimbabwe. Various expansion options in this regard are currently being investigated. A future expansion could involve the development of underground mines, another concentrator, a dam as well as a new smelter.

Given the right market conditions, Zimplats with its large reserves and easy underground access, has the potential to become a 1-million-ounce–per-annum platinum producer.
