Mr Chung,
You are absolutely correct. The main similarity between our "coal" and the thermal coal talked about is the colour. But just pointing out that there is still a lot of interest in "coal" and as we will be producing higher value and much rarer Anthracite[Met. coal] there will be a shortage from 2015 and we can only expect even greater demand and prices wether it is pulled from Mbila or Kangwane
Cheers Chooky
