Operations Review (Part 1) - Anglo Platinum

Operations Review (continued)Overview: ProjectsModikwa Platinum Mine; joint venture with African Rainbow Minerals (ARM)Safety: Modikwa recorded a safety performance better than planned for both lost-timeand reportable injuries. This was achieved with mainly a novice workforce sourced from thelocal community. From inception, Modikwa’s safety effort hasbeen based on the BBS initiative. One fatality was recorded.Mining: The concentrator was commissioned in the second halfof the year and achieved the design throughput of 200 000 tonsper month in September 2002. Recoveries were better thanplanned. The initial stoping performance has been pleasing, andthe build-up in ounces produced is in line with the very hightargets set for this project.Modikwa has been successful in employing mainly localpersonnel where possible.A view of the new robotequipped laboratory on trial atAnglo Platinum’s Research Centrebefore being moved to theModikwa Platinum Mine.

The concentrator was successfullycommissioned as planned in February 2002 and performed well,achieving designed recoveries. The production build-up from theWaterval mine has been steep, but was slower than expecteddue to delays in development caused by congestionunderground. Stoping widths in the UG2 areas of the Brakspruit,Bleskop and Paardekraal shafts were increased toinclude the leader seam and reduce the risk offalls of ground, causing a reduction in headgrade. Test work has been done to provemethods of improving the mill feed grade, withimplementation to take place during 2003.The project added R451,4 million to the Group’soperating contribution for the year under review.Recently, the Group announced Phase 2 of theRustenburg UG2 project being a replacementproject for existing production rather than anexpansion.
