26 May 2004 First production of high grade ore from the underground mining operation
![Page 30: Welcome [] · KMF divided into HIGH GRADE and ...](https://reader031.fdocuments.us/reader031/viewer/2022020114/5b51e3dc7f8b9a6b118cad02/html5/thumbnails/30.jpg)
NCHWANING 3 PROJECT Contingency plan
l In order to offset the negative effects of the delayed project a temporary ore pass was introduced
l This allowed for 409 633 production tons since 26 May 2004
l All the production was specifically suited to Cato Ridge, resulting in improved efficiencies.

THE FUTURE THE FUTURE l ASSMANG have access to an excellent high grade orebody on the No 1 manganese seam.
l ASSMANG can relatively easily access and mine the No 2 medium grade orebody to supply blast and electric furnaces.
l ASSMANG has made significant capital investments to position for future demand.
l Sales volumes are increasing while operating costs are improving.
l ASSMANG is actively pursuing continuous improvement policies
![Page 35: Welcome [] · KMF divided into HIGH GRADE and ...](https://reader031.fdocuments.us/reader031/viewer/2022020114/5b51e3dc7f8b9a6b118cad02/html5/thumbnails/35.jpg)
FUTURE PLANS FUTURE PLANS l ASSMANG aims to be a reliable supplier of high grade ore for the next 30 years.
l ASSMANG aims to significantly grow market share in China by supplying medium grade to the blast and electric furnaces.
l This strategy could see a doubling of ore output within the next 6 to 8 years.
l ASSMANG is committed to optimising the available ore resources by constructing DMS and Sinter facilities by 2010.
l ASSMANG will remain aggressively involved in the logistics of ore transport and shipping to ensure the anticipated volume growth
