Nope, you're wrong. Lots of words, but you are wrong, and you continue to use a circular argument. It will be interesting to see if the geologists associated with the project insist on a correction in a PR. We'll see how much they value their reputations and credibility.
This much is very clear in your statement:
Think about this, using your logic of how you came up with the 40-fold factor (and not the actual 800-fold factor) for a 50 pound original sample :
If they had started with a 100 pound sample, and concentrated down to an ounce....you would use a 20 fold factor, using your logic.
If they had started with a 500 pound sample and concentrated down to an ounce....you would use a 4 fold factor, using your logic.
If they had started with a 2000 pound sample and concentrated down to an ounce, you would use a one fold factor. The concentrate result would equal the assay of the entire 1 ton original sample. A concentrate assay equals the assay of a one-ton original sample? Does that make any sense at all? Nope. Your logic on how they came up with the factor to divide into your concentrate assay........is completely wrong.
