ACZ Laboratories, Inc. Inorganic Extended
2773 Downhill Drive Steamboat Springs, CO 80487 [phone] Qualifier Report
Thorin Resources ACZ Project ID: L86570
ACZ ID WORKNUM PARAMETER METHOD QUAL DESCRIPTION
L86570-01 VVG586211 Aluminum(1312) M6010D ICP RA Relative Percent Difference(RPD)was not used for data
validation because the concentration of the duplicated
sample is too low for accurate evaluation(<10x MDL).
M60100 ICP ZG The ICP or ICP-MS Serial Dilution was not used for data
validation because the sample concentration was less than
50 times the MDL.
WG586576 Beryllium(1312) M6020B ICP-MS RA Relative Percent Difference(RPD)was not used for data
validation because the concentration of the duplicated
sample is too low for accurate evaluation(<10x MDL).
WG586499 Bicarbonate as CaCO3 SM 2320 B-2011 06 Sample was received above recommended temperature.
WG586211 Boron(1312) M6010D ICP RA Relative Percent Difference(RPD)was not used for data
validation because the concentration of the duplicated
sample is too low for accurate evaluation(<10x MDL).
WG586304 Bromide(1312-DI) M300.0-Ion Chromatography M2 Matrix spike recovery was low,the recovery of the
associated control sample(LCS or LFB)was acceptable.
M300.0-Ion Chromatography RA Relative Percent Difference(RPD)was not used for data
validation because the concentration of the duplicated
sample is too low for accurate evaluation(<10x MDL).
WG586576 Cadmium(1312) M6020B ICP-MS RA Relative Percent Difference(RPD)was not used for data
validation because the concentration of the duplicated
sample is too low for accurate evaluation(<10x MDL).
WG586623 Carbon,total organic(TOC)(1312-DI) SM 5310 B-2011/2014 HD Analysis is outside the intended scope of the method,which
does not provide hold time information for soil extracts. No
hold time is observed for collection to extraction. The
referenced method hold time is observed for extraction-to-
analysis.
SM 5310 13-2011/2014 06 Sample was received above recommended temperature.
SM 5310 B-2011/2014 RA Relative Percent Difference(RPD)was not used for data
validation because the concentration of the duplicated
sample is too low for accurate evaluation(<10x MDL).
WG586499 Carbonate as CaCO3 SM 2320 B-2011 06 Sample was received above recommended temperature.
WG586304 Chloride(1312-DI) M300.0•Ion Chromatography HD Analysis is outside the intended scope of the method,which
does not provide hold time information for soil extracts. No
hold time is observed for collection to extraction. The
referenced method hold time is observed for extraction-to-
analysis.
M300.0-Ion Chromatography RA Relative Percent Difference(RPD)was not used for data
validation because the concentration of the duplicated
sample is too low for accurate evaluation(<10x MDL).
WG586576 Chromium(1312) M60208 ICP-MS RA Relative Percent Difference(RPD)was not used for data
validation because the concentration of the duplicated
sample is too low for accurate evaluation(<10x MDL).
Cobalt(1312) M60208 ICP-MS RA Relative Percent Difference(RPD)was not used for data
validation because the concentration of the duplicated
sample is too low for accurate evaluation(<10x MDL).
WG586499 Conductivity©25C(1312-DI) SM 2510 B-2011 Q6 Sample was received above recommended temperature.
WG586646 Copper(1312) M6020B ICP-MS RD For a solid matrix,the duplicate RPD(spike or matrix)
exceeded the control limit,which is attributable to the non-
homogeneity of the sample.
W0586467 Fluoride(1312 DI) SM 4500-F C-2011 RA Relative Percent Difference(RPD)was not used for data
validation because the concentration of the duplicated
sample is too low for accurate evaluation(<10x MDL).
WG586499 Hydroxide as CaCO3 SM 2320 B-2011 Q6 Sample was received above recommended temperature.
WG586211 Iron(1312) M60100 ICP RA Relative Percent Difference(RPD)was not used for data
validation because the concentration of the duplicated
sample is too low for accurate evaluation(<10x MDL).
Lithium(1312) M6010D ICP RA Relative Percent Difference(RPD)was not used for data
validation because the concentration of the duplicated
sample is too low for accurate evaluation(<10x MDL).
Magnesium(1312) M6010D ICP RA Relative Percent Difference(RPD)was not used for data
validation because the concentration of the duplicated
sample is too low for accurate evaluation(<10x MDL).
WG586206 Mercury(1312) M7470A CVAA Q6 Sample was received above recommended temperature.
M7470A CVAA RA Relative Percent Difference(RPD)was not used for data
validation because the concentration of the duplicated
