7. MINDEV SUBSIDIARIES • Tollsort: with Mikrosort of Germany, to apply new optical sorting technology to improve recoveries in the southern African minerals industry; • Musuku: with Harmony and BEE company, to beneficiate gold bullion into pure (99.99%) gold and into value-added intermediate products such as salts, wire, alloys, bars and high purity gold for electronics, using Mintek technologies. Musuku is the Venda word for gold. • Mogale: with management, workers and BEE company, to treat Columbus stainless steel dusts to produce a valuable nickel alloy and to produce ferrochrome using Mintek’s new “Enviroplas” technology, but based on its early DC FeCr technology that was taken over by Samancor in 1993. • Atoll: with Bateman (outsourcing some operations to BEE companies), was established prior to Mindev’s formation to provide toll processing services to the ferro-alloys industry to recover valuable alloys from slag dumps

8. FEASIBILITY STUDIES INITIATED • A coastal Electrolytic Manganese Dioxide (EMD) plant based on SA’s abundant manganese ores. EMD is used in the manufacture of dry-cell batteries • A Hot Briquetted Iron (HBI) plant based on SA’s iron ore fines. HBI is used in steel making • A coastal ferro-nickel (FeNi) plant based on SA’s cheap electricity and imported laterite ores. FeNi is used in stainless steel production • A plant to recover platinum concentrate from chromite tailings dumps (the Platdumps project)

11. RESOURCE-BASED SUSTAINABLE DEVELOPMENT • The RBSD thesis has been incorporated into the National R&D Strategy • The overall objective and aim of the RBSD project is to identify the critical factors and necessary conditions (i.e. “lessons”) required for a resource-based economy such as South Africa to make the transition to a high-tech industrialised state • Study trip to Sweden and Finland to build a research network • Mining Inputs Cluster • Mintek has also been tasked with facilitating the development of a mineral processing inputs cluster (consumables, capital goods, services) • Mintek proceeded to initiate the resuscitation of the South African mining cluster and has received the commitment of various industry, government, science council, and organisational support for this endeavour • Defining the inputs cluster in terms of key product categories and the type of goods and services associated with them. • Putting together a database of leading South African and international firms associated with the domestic mining and mineral processing sector. • Funding proposal has been submitted to Fridge Mineral Economics and Strategy Unit

13. RURAL DEVELOPMENT & POVERTY ALLEVIATION • Kgabane Project • The Kgabane Jewellery and Craft Project was initiated by the Ministry of Minerals and Energy to alleviate poverty and create jobs through the creation of a vibrant and inclusive jewellery industry and taking advantage of existing resources • The project was formally launched in October 2002 during the Mining Week, with a jewellery show. The launch celebrated the Kgabane – Harmony range, which was realised through its partnership with Harmony Gold • A Production and Training Unit has been set up and is operational. The unit is tasked with the creating a range of jewellery products that will be inspired by rural - indigenous craft designs and will utilise a range of materials ranging from natural fibres, beads, ceramics, precious and semi-precious metals and stones • Through the Kgabane Rural Development Jewellery Project, seven groups of crafts-women from rural and urban impoverished areas have been set up and are receiving training according to the unit standards qualification set with the Mining Qualifications Authority Mineral Economics and Strategy Unit
