The document examines the concept of 'metal companionship,' where critical metals are often produced as co-products or by-products of major 'host' metals rather than as primary targets. This dependency creates significant supply inelasticity, price volatility, and risks of material loss in tailings. The author argues that understanding these associations can help identify new sources of metals, such as reprocessing mine waste, and inform national development strategies for producer countries.

The report finds that the Bargny-Sendou area already suffers from severe air pollution, with PM10 levels exceeding national standards by 193% to 540% before the full operation of new industrial projects. It argues that the cumulative impact of the coal plant, mineral port, and steel plant will exacerbate health risks and degrade local resources, including the livelihoods of 1,000 women processing fish at the Khelcom site. The study recommends a strategic environmental assessment of the zone and the conversion of the coal plant to gas.

The document details South Africa's coal landscape, identifying the Highveld and Witbank coalfields as the largest by reserves. It provides a comprehensive inventory of mines, their ownership (including major entities like Anglo Coal, Exxaro, and BHP Billiton), and their production outputs for domestic power (primarily Eskom) and export markets. The report also analyzes the logistics chain, focusing on the Richards Bay Coal Terminal (RBCT) as the primary export hub, and provides detailed cost breakdowns for opencast mining and rail transport.
