A scoping study is under way into the self-generation of electricity for Assmang’s mines – but not its smelters, Assore CEO Charles Walters said on Friday, when the company reported interim results that were negatively affected by weaker chrome and manganese prices, and lower shipments of iron-ore in the six months to December 31. Assmang, which Assore owns jointly with Patrice Motsepe’s African Rainbow Minerals, provides three of Assore’s four commodities – iron-ore, manganese ore and manganese alloys – and Assore’s exposure to chrome ore is through its ownership of the Dwaarsrivier Chrome Mine.
