total revenue for rocklands $us17.8 billion, page-52

Janti, we are not talking about a cubic metre, we are talking about 1 Tonne, which weighs 1000kgs, regardless of the SG.

Therefore there maybe less volume in the 1 tonne with an SG of 2.6, but unfortunately it will still only weigh 1 Tonne.

As the grade percentages we are talking about are as a percentage per Tonne, the SG is irrelevant, 1 tonne will still = 1000kg, unless the world has changed recently and I missed something,

cheers
