I spoke to S.M, who is difficult to communicate with.
But re-reading, it appears the 300M tonnes announced is 43% of Waterburg 1.
So there is another 400M tonnes possibly there.
Then W3 & W3 plus Ledjadja, which appears to have a better resource, both in terms of quantity and quality.
So it appears tonnage of saleable coal will easily be 1.5 billion tonnes.
