Yeah...all the mills around the world doing PARTIAL extractions are massively undercalling things by your logic.

Partial extraction could be any amount. Your long running suggestion than anything less than around 5oz is due to partial extraction is very unlikely, especially in a homogeneous distribution through the host rock.

“If”, “might”, “potentially”.....lots of uncertainty in each of your bold statements. Potentially the extraction results are going to be >90% vs true.
