Oi F. ^:.:'1 -(~ 9:i%E.~il~li~,i <br />Our December 22 cyanide analysis are complete and so this will <br />be our 1985 yearly summary. <br />We presently have over eig:it (8) feet of freeboard in our pond <br />and our last samples were taken through twelve (12) inches of ice. <br />I will tabulate the analyses below: <br />PONll SEDIMENT <br />DATE TOTAL CYANIDE <br />8/2/85 31.3 ppm <br />12/22/85 30.3 ppm <br />POND LIQUOR <br />DATE ~N TOTAL CYANIDE <br />8/2/85 8.5 4.01 ppm <br />12/22/85 7.5 0.28 ppm <br />CYANIDE AMEN. '1'0 C1 <br />26.0 ppm <br />30.3 ppm <br />CYANIDE AMEN. TO C1 <br />3.96 ppm <br />0."28 ppm <br />WAD <br />0.746 ppm <br />3.8 ppm <br />WAll <br />2.63 ppm <br />0.16 ppm <br />As you recall my free cyanide analysis of the liquor of 8/2/85 was <br />2.5 ppm by electrode which compares quite well with Hazen's 2.63 ppm. <br />On the sample of 12/22/85 I obtained 0.134 ppm free cyanide which again <br />compares well with Nazen's .16 ppm. The effect of Cot absorption and <br />low air pressure appears to cause rapid depletion of cyanide in our <br />pond. <br />Regards, <br />~a~ ~ ~~n <br />Mike Klein <br />Mill Superinte~ident <br />MK/fg <br />cc: File <br />Enclosures: Lab Reports <br />
