properly operating for the next bi-weekly sampling event on <br />March 19-20. Also, during the time of this sampling event, <br />maintenance activities on the leach deck prevented the <br />collection of the pre-detox process point sample. <br />The initial analysis by Core Labs of the cyanide samples for <br />the upper pond (930304 BMG 04), the lower pond (930309 BMG <br />OS), and the collection pond (930305 BMG O1) showed CN-wad <br />values greater than CN-total values. The unfiltered initial <br />results for the upper pond were 0.18 ppm CN-wad and o.14 ppm <br />CN-total, for the lower pond were 0.30 ppm CN-wad and <br />0.17 ppm CN-total, and for the collection pond were 0.63 ppm <br />CN-wad and 0.58 ppm CN-total. The samples were re-analyzed. <br />The collection pond sample re-analysis showed 0.68 ppm <br />CN-wad and 0.73 ppm CN-total. However, the upper and lower <br />pond samples continued to show higher CN-wad than CN-total <br />values. The unfiltered re-analysis results for the upper <br />pond were 0.15 ppm CN-wad and o.04 ppm CN-total and for the <br />lower pond were 0.26 ppm CN-wad and 0.03 ppm CN-total. Core <br />Labs is investigating the cyanide analysis results and will <br />be in contact with Dr. Adrian Smith to discuss the andlysis <br />results. It should be noted that all cyanide values <br />reported for the upper, lower, and collection ponds were <br />below permit limits. <br />If you have any questions, please call. <br />Sincerely, <br />~~,na ~~ <br />Alana L.
