"As a result of the discounting of Inferred Resources previously published, the
overall resource result is significantly lower at 639,400 oz, down from 4,188,932 oz."

I am totally puzzled. How can a JORC resource be downgraded so much? Can anyone with a bit of geological knowledge explain that to me. I understand that when they state the size of a resource, it is only a estimation, but surely such a large reduction is not normal? After all, isn't that what a JORC is all about - giving some sort of certainty?
