The initial analysis by Core Labs of the cyanide sample for <br />the lower pond (930203 BMG 03) showed a CN-wad value <br />(0.27 ppm) greater than the CN-total value (0.24 ppm). <br />Also, as noted above the holding time for the initial total <br />cyanide analysis was exceeded. The sample was re- <br />analyzed;the results of the re-analysis were 0.08 ppm CN-wad <br />and 0.16 ppm CN-total. Both reports are attached. <br />Core Labs reported values of 0.03 ppm CN-total for the RS-5 <br />station (930203 BMG O1) and a CN-wad value (0.03 ppm) <br />greater than the CN-total value (<0.02 ppm) for well M-9. <br />An insufficient volume of sample remained for re-analysis. <br />Both values are believed to be lab error as the practical <br />quantitative limit of detection for cyanide is 0.04 ppm. <br />These locations will be re-checked during future bi-weekly <br />sampling events. <br />If you have any questions, please call. <br />Sincerely, <br />f-1Yc+na~' ~~ <br />Alana L.
