This collection of assays is arranged by test location and includes photos of the ore samples from each location. Each assay is marked with the depth the sample was retrieved from. The assays include sophisticated assays from Advanced Analytical and XRF assays of the untreated ore. These two methods can be used to more or less bookend the recoveries possible from each sample, with XRF showing the minimum and the sophisticated showing the maximum.
