ACZ Laboratories, Inc. 2773 Downhill Drive Steamboat Springs, CO 80487 (800) 334 -5493 Silver Star Resources, LLC ACZ Project ID: L92784 ACZ 10 WORKNUM PARAMETER METHOD QUAL DESCRIPTION L92784-06 WG317347 Silver, dissolved M200.8 ICP -MS M2 Matrix spike recovery was low, the recovery of the associated control sample (LCS or LFB) was acceptable. M200.8 ICP -MS ZA Poor recovery for Silver quality control is accepted due to low Silver solubility in samples, digestates, or extracts that do not contain sufficient Hydrochloric add. WG317213 Chloride SM4500CI -E M2 Matrix spike recovery was low, the recovery of the associated control sample (LCS or LFB) was acceptable. WG317290 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 (< 10x MDL). WG317287 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 MOL). WG317248 Fluoride SM4500F -C RA Relative Percent Difference (RPD) was not used for data validation because the sample concentration is too low for accurate evaluation (< 10x MDL). WG317374 Nitrate/Nitrite as N M353.2 - H2SO4 preserved RA Relative Percent Difference (RPD) was not used for data validation because the sample concentration is too low for accurate evaluation (< 10x MDL), WG316982 Phosphorus, ortho dissolved M365.1 - Automated Ascorbic HE Analysis performed past holding time. Method holding time Add is less than or equal to 7 days and sample was received with less than half of the holding time remaining (refer to item C5 of ACZs Terms & Conditions). M365.1 - Automated Ascorbic RA Relative Percent Difference (RPD) was not used for data Add validation because the sample concentration is too low for accurate evaluation (< 10x MDL). WG317096 Residue, Non Filterable (TSS) @105C SM2540D RA Relative Percent Difference (RPD) was not used for data validation because the sample concentration is too low for accurate evaluation (< 10x MDL). WG317343 Sulfate D516 -02 - Turbddimetric 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.

ZA Poor recovery for Silver quality control is accepted due to low Silver solubility in samples, digestates, or extracts that do not contain sufficient Hydrochloric add. RA Relative Percent Difference (RPD) was not used for data validation because the sample concentration is too low for accurate evaluation (< 1 Ox MDL). RA Relative Percent Difference (RPD) was not used for data validation because the sample concentration is too low for accurate evaluation (< IOx MDL). RA Relative Percent Difference (RPD) was not used for data validation because the sample concentration is too low for accurate evaluation (< 1 Ox MDL). RA Relative Percent Difference (RPD) was not used for data validation because the sample concentration is too low for accurate evaluation (< 10x MDL). HE Analysis performed past holding time. Method holding time is less than or equal to 7 days and sample was received with less than half of the holding time remaining (refer to item C5 of ACZs Terms & Conditions). RA Relative Percent Difference (RPD) was not used for data validation because the sample concentration is too low for accurate evaluation (< 10x MOIL). RA Relative Percent Difference (RPD) was not used for data validation because the sample concentration is too low for accurate evaluation (< 10x MDL). M3 The spike recovery value is unusable since the analyte concentration in the sample is disproportionate to the spike level.
