Id., <br /> at Appendix 1 B. <br />Table C-2, Whole Rock Analysis Table 1 (Whole Rock Analysis) Mine <br /> Rock Analysis. Id. <br />Table C-3, USGS Field Leach Test No field leach test undertaken. See SPLP <br /> analysis. Id., Table 3, Appendix 113. <br />Table C-4, SPLP Metal Analysis Table 3 (Synthetic Precipitation Leachate <br /> Precipitation), Mine Rock Analysis. Id. <br />Table C-7, Water Analysis - Mine Adits The Lower Idaho Adit Seep has been re- <br /> interpreted as the Idaho Seep. See Tables <br /> 2 (Dissolved Metal Concentrations), <br /> 3(Total Metal Concentrations) and 4 <br /> (Surface Water Chemistry), Surface <br /> Water Analysis. Id., Appendix 1A. <br />28-3. Total Quant is regarded as a semi-quantitative method with accuracy of 150%. <br />Therefore, DBMS will add 50% to each analytical result in evaluations of potential <br />impacts. The operator has the option of providing more quantitative analyses. <br />Response to Adequacy Issue No. 28-3: The results from a composite mine rock <br />sample collected from a stockpile located on the bench near the May Day Portal No. 1 was <br />summarized in a letter dated June 24, 2010. Id., at Appendix 1B. Whole rock analyses was <br />undertaken by X-ray fluorescence and reported in Table 1 of Appendix 1 B. <br />28-4. Section 63.3(1)(i). The descriptions ofsamples for the FLT and whole rock <br />analyses are inadequate. DRMS needs to know precisely what rock was sampled <br />and where, supplemented with photographs of the sampled material and location(s) <br />on the ground from where they were sampled. <br />Response to Adequacy Issue No. 28-4: A composite mine rock sample collected <br />from a stockpile located on the bench near the May Day Portal No. 1 as reported to Wildcat <br />Mining in a letter dated June 24, 2010. Id. This report includes sample location and <br />photographs. Whole rock analyses was undertaken by X-ray fluorescence and reported in <br />Table 1 of Appendix 1B.
