ACZ Laboratories, Inc. 2773 Downhill Drive Steamboat Springs, CO 80487 (800) 334 -5493 Star Mine Operations LLC ACZ Project ID: L16199 L16199.11 WG357502 Beryllium, dissolved M200.8 ICP -MS MA Recovery for either the spike or spike duplicate was outside of the acceptance limits; the RPD was within the acceptance limits. WG357726 Copper, dissolved M200.8 ICP -MS M3 The spike recovery value is unusable since the analyte concentration in the sample is disproportionate to the spike level. The recovery of the associated control sample (LCS or LFB) was acceptable. WG357326 Iron, dissolved M200.7 ICP M3 The spike recovery value is unusable since the analyte concentration in the sample is disproportionate to the spike level. The recovery of the associated control sample (LCS or LFB) was acceptable. Manganese, dissolved M200.7 ICP M3 The spike recovery value is unusable since the analyte concentration in the sample is disproportionate to the spike level. The recovery of the associated control sample (LCS or LFB) was acceptable. WG357522 Silica, total M200.7 ICP ZS Digestion procedures have the potential to trigger silica polymerization and precipitation, leading to low biased results. Silica chemistry is complex and polymerization kinetics are unpredictable. Dissolved and/or acid soluble silica analyses may provide more accurate measurements. WG357326 Zinc, dissolved M200.7 ICP M3 The spike recovery value is unusable since the analyte concentration in the sample is disproportionate to the spike level. The recovery of the associated control sample (LCS or LFB) was acceptable. WG357541 Chloride SM4500CI -E RA Relative Percent Difference (RPD) was not used for data validation because the sample concentration is too low for accurate evaluation (< 1 Ox MDL). WG357353 Cyanide, total M335.4 - Colorimetric w/ RA Relative Percent Difference (RPD) was not used for data distillation validation because the sample concentration is too low for accurate evaluation (< 1 Ox MDL). WG357361 Cyanide, WAD SM4500 -CN I- Colorimetric w/ RA Relative Percent Difference (RPD) was not used for data distillation validation because the sample concentration is too low for accurate evaluation (< 10x MDL). WG357415 Fluoride SM450OF -C M2 Matrix spike recovery was low, the recovery of the associated control sample (LCS or LFB) was acceptable. SM450OF -C RA Relative Percent Difference (RPD) was not used for data validation because the sample concentration is too low for accurate evaluation (< 1 Ox MDL). WG357006 Phosphorus, ortho dissolved M365.1 - Automated Ascorbic RA Relative Percent Difference (RPD) was not used for data Acid validation because the sample concentration is too low for accurate evaluation (< 10x MDL). WG357040 Residue, Non - Filterable (TSS) @105C SM2540D Q1 Sample integrity was not maintained. See Case Narrative. SM2540D RA Relative Percent Difference (RPD) was not used for data validation because the sample concentration is too low for accurate evaluation (< 10x MDL). WG357482 Sulfate D516 -02 - Turbidimetric M3 The spike recovery value is unusable since the analyte concentration in the sample is disproportionate to the spike level. The recovery of the associated control sample (LCS or LFB) was acceptable. REPAD.15.06.05.01 Page 74 of 79
