Ann: Gold Extraction Results from Ema and Tres Estados, page-124

From the ANN: "As the extraction methodology is still in the developmental phase it may represent only a partial recovery method for gold and other precious metals."

Hydro- vs pyrometallurgical techniques yield different results for different metals.

That method didn't pick up the PGMs, or it could be variability in the metal ratios between samples. There'll be some zonation within the orebody although everything is super insane high grade.
