J46oL Laboratories, Inc. <br />2773 Downhill Drive Steamboat Springs, CO 80487 (800) 334 -5493 <br />Peabody Sage Creek Mining, LLC August 01, 2014 <br />Project ID: 451288047 <br />ACZ Project ID: L19002 <br />ACZ Laboratories, Inc. (ACZ) received 10 miscellaneous samples from Peabody Sage Creek Mining, LLC on June 19, <br />2014. The samples were received in good condition. Upon receipt, the sample custodian removed the samples from the <br />cooler, inspected the contents, and logged the samples into ACZ's computerized Laboratory Information Management <br />System (LIMS). The samples were assigned ACZ LIMS project number L19002. The custodian verified the sample <br />information entered into the computer against the chain of custody (COC) forms and sample bottle labels. <br />Any analyses not performed within EPA recommended holding times have been qualified with an "H" flag. <br />R h Y <br />These samples were analyzed for inorganic parameters. The individual methods are referenced on both, the ACZ invoice <br />and the analytical reports. The extended qualifier reports may contain footnotes qualifying specific elements due to QC <br />failures. In addition the following has been noted with this specific project: <br />1. This project has had all Selenium analysis matrix spiked to determine potential matrix interference. All recoveries were <br />within ACZ's and method acceptance criteria of 70 -130 %. Please review the QC Summary for specific recovery <br />information. In general the total recoverable fraction is biased higher than the equivalent dissolved due to the samples <br />matrix. <br />2. This project has been revised to report a re- analysis of Total Dissolved Solids on L19002 -07. It appears that an incorrect <br />dilution factor was originally reported. <br />3.
