"But how is there a "smaller quantity of even better grades" ??

My comment was simply that most will look at the numbers and see less % only, and forget that it adds more overall ore."

There is a smaller quantity of high percentage vs. the much larger deposit of lower percentage. It's nice to have both. If individuals cannot add the two together then rudimentary math instruction is required.

What really matters is that the players that count, those majors that will ultimately drive the price higher from the own understanding of the value, will be our concern. Not those who are unable to do basic math.
