"If assays replicate the (PARTIAL) extraction values, then it confirms the accuracy of both"???

If assays replicate the extraction values, then there's been a major screw up.

The assays purpose is to measure the true grade.  100% of it. The PARTIAL extraction results measure what might be regarded as an metallurgically extractable portion of the true grade. Less than 100%. It's a proxy for a commercial extraction method.

Also the extraction results are from TESTWORK, so a lot of them will have failed and will be a long, long way from being anywhere near 100% the true grade.

....which is why the assay results will potentially show a massive increase in the grades compared to the extraction results to date.
