Operational review

Marula, Limpopo

Challenging operating environment

Marula location [map]
  • Two on-reef decline shafts and one off-reef conventional decline
  • Concentrator plant
  • Reserves: 1.7 million attributable ounces of platinum
  • Resources (including reserves): 8.2 million attributable ounces of platinum
  • Production: 74 000 ounces of platinum in concentrate
  • Labour complement (including contractors): 3 510

Marula had a difficult year characterised by an unsatisfactory safety performance, a slower-than-expected ramp-up in production, reduced productivity and persistent labour issues. This operation has been affected by the economic slowdown, and the steep decline in the rhodium price in particular.

Sadly, one of our employees lost his life at work during the year, whilst the lost-time injury frequency rate (LTIFR) more than trebled from the previous year. Strict disciplinary action is being taken to ensure compliance with standards and procedures. However, it is visible, felt leadership that remains the key to a safer working environment.

The 1.57 million tonnes milled, though slightly up on the previous year, was well short of the operation’s internal target as the production ramp-up once again fell behind schedule. This failure can be attributed to a lack of adequate on-reef development, which resulted in a lack of face availability and, consequently, limited mining flexibility.

Grade fell slightly as production from the higher-grade Driekop shaft declined, and on-reef development at the Clapham shaft increased. Team efficiencies and productivity were of concern, and were impacted by the introduction of new teams to the conventional section as well as safety stoppages and industrial action during the year. As a consequence, platinum production rose only a disappointing 5% to 74 000 ounces in concentrate.

Unit costs (excluding share-based payments) escalated 30% on the back of the high inflationary environment and lower throughput and efficiencies. Including share-based payments, unit costs increased by 14% to R11 243 per platinum ounce. Increased volumes and higher efficiencies should contain costs going forward. The retention of skills remained an issue, especially in terms of personnel to maintain the trackless equipment.

Outlook

Marula has a difficult year ahead as it focuses on continuing its ramp-up to full production and ensuring profitability. The ongoing viability of the operation will be determined not only by higher metal prices and more favourable exchange rates, but also by a safer working environment, good cost management and improved operational performance — all of which are receiving concerted management attention.

Production at Driekop will cease in 2010 as mining reaches the property boundary. This could, however, be extended if a mineral reserve agreement is concluded with neighbouring Modikwa mine, an option that is currently being explored. Increased production from Clapham, and in particular the rise in conventional mining, will improve the grade by around 15%. The ongoing development to a more conventional mine layout at Marula is anticipated to achieve full production of 125 000 ounces per annum within a five-year window.

The feasibility study on the exploitation of the Merensky Reef at Marula was completed during the year, but has been put on hold until market conditions improve.

Marula chrome initiative to benefit local communities

In line with our commitment to social upliftment, a joint venture, Makgomo Chrome, between Implats, Marula and Marula Community Chrome, has been established to extract and market the chrome contained in the current UG2 tailings produced by the Marula operation. The benefits of this business will flow through to six local communities. Implats will fund the design, engineering, construction and commissioning of the plant. Full production is anticipated to be 125 000 tonnesof chrome per annum.
