Gray, it is context. Yes, the grades are on average 1.5%; that's not a lie and gives a good indication of how the source compares to what other producers are refining. But no one recovers 100% and the recovered content is generally referred to by absolute amount as that is what is sold and used to calculate revenue, not percentage of that available in the ore which is a pure measure of process efficiency which can be affected by so many things.
