AUZ Laboratories, Inc. <br />2773 Downhill Drive Steamboat Springs, CO 80487 (800) 334-5493 <br />Fortune Revenue Silver Mines Inc ACZ Project ID: L24100 <br />10 WORKNUM PARAMETER <br />METHODACZ 1, <br />��QUAL <br />DESCRIPTION <br />L24100-01 WG383271 Total Hot Plate Digestion <br />M200.2 ICP -MS <br />DJ <br />Sample dilution required due to insufficient sample. <br />WG383269 Total Recoverable Digestion <br />M200.2 ICP -MS <br />DJ <br />Sample dilution required due to insufficient sample. <br />WG383316 Lead, total <br />M200.8 ICP -MS <br />M3 <br />The spike recovery value is unusable since the analyte <br />concentration in the sample is disproportionate to the spike <br />level. The recovery of the associated control sample (LCS <br />or LFB) was acceptable. <br />WG383286 Mercury, total <br />M245.1 CVAA <br />DJ <br />Sample dilution required due to insufficient sample. <br />WG383246 Chloride <br />SM4500CI-E <br />M2 <br />Matrix spike recovery was low, the recovery of the <br />associated control sample (LCS or LFB) was acceptable. <br />SM4500CI-E <br />RA <br />Relative Percent Difference (RPD) was not used for data <br />validation because the sample concentration is too low for <br />accurate evaluation (< 10x MDL). <br />WG383204 Cyanide, total <br />M335.4 - Colorimetric w/ <br />M1 <br />Matrix spike recovery was high, the recovery of the <br />distillation <br />associated control sample (LCS or LFB) was acceptable. <br />M335.4 - Colorimetric w/ <br />RA <br />Relative Percent Difference (RPD) was not used for data <br />distillation <br />validation because the sample concentration is too low for <br />accurate evaluation (< 10x MDL). <br />WG383201 Cyanide, WAD <br />SM4500-CN I,E-Colorimetric w/ <br />RA <br />Relative Percent Difference (RPD) was not used for data <br />distillation <br />validation because the sample concentration is too low for <br />accurate evaluation (< 10x MDL). <br />WG382887 Dissolved Chromium, Hexavalent <br />SM3500Cr-B <br />H3 <br />Sample was received and analyzed past holding time. <br />SM3500Cr-B <br />CD <br />Reported value is the background -corrected concentration, <br />as described by the method. <br />SM3500Cr-B <br />RA <br />Relative Percent Difference (RPD) was not used for data <br />validation because the sample concentration is too low for <br />accurate evaluation (< 10x MDL). <br />WG383300 Fluoride <br />SM450OF-C <br />M2 <br />Matrix spike recovery was low, the recovery of the <br />associated control sample (LCS or LFB) was acceptable. <br />SM450OF-C <br />RA <br />Relative Percent Difference (RPD) was not used for data <br />validation because the sample concentration is too low for <br />accurate evaluation (< 10x MDL). <br />WG382891 Phosphorus, ortho dissolved <br />M365.1 - Automated Ascorbic <br />QP <br />The sample was filtered at the laboratory more than 15 <br />Acid <br />minutes after sample collection. For Orthophosphate, 40 <br />CFR Part 136.3 requires filtration within 15 minutes of <br />collection. <br />M365.1 -Automated Ascorbic <br />RA <br />Relative Percent Difference (RPD) was not used for data <br />Acid <br />validation because the sample concentration is too low for <br />accurate evaluation (< 10x MDL). <br />M365.1 -Automated Ascorbic <br />ZU <br />Analysis date/time preceeds filter date/time. A portion of <br />Acid <br />sample was filtered and analyzed prior to the creation of a <br />Filter workgroup. <br />WG382936 Residue, Filterable (TDS) @180C <br />SM2540C <br />RA <br />Relative Percent Difference (RPD) was not used for data <br />validation because the sample concentration is too low for <br />accurate evaluation (< 10x MDL). <br />WG382941 Residue, Non -Filterable (TSS) @105C <br />SM2540D <br />RA <br />Relative Percent Difference (RPD) was not used for data <br />validation because the sample concentration is too low for <br />accurate evaluation (< 10x MDL). <br />WG383198 Sulfate <br />D516-02/-07 - Turbidimetric <br />M3 <br />The spike recovery value is unusable since the analyte <br />concentration in the sample is disproportionate to the spike <br />level. The recovery of the associated control sample (LCS <br />or LFB) was acceptable. <br />REPAD.15.06.05.01 <br />L24100-1505151408 Page 21 of 31 <br />
