Abstract from Paydirth CCC presentation(Page 2 first paragraph, attachment provided at the bottom )
"As mining picked up, Eskom?s on-site sampling programme began identifying problems with the quality of the stockpiles"
"CCC started picking up problems in the last six months. Vlakvarkfontein is low quality anyway ? we need 20% volatiles, 20% CV, 30% ash and 1.2% sulphur to meet Eskom?s needs ? but as Eskom came to sample our stockpiles we were getting REJECTIONS."
"Continental and Trollope returned to geological work to gain a more effective understanding of where in the two, 5m coal seams, the rejections were coming from.
In 4 Seam the top 1.8m was of very low quality, bringing down the averages towards rejection"
